mSATA connector promises smaller netbooks; Toshiba launch first mSATA SSDs

Chris Davies — Tue, 22 Sep 2009 08:16:58 +0000

If there’s one thing we’re crying out for, it’s another netbook connector standard. Happily the SATA-IO working group have delivered just that in the shape of mini-SATA (or mSATA), a new low-profile connector supporting 1.5Gb/s and 3.0Gb/s transfer rates but with a slightly smaller plug. To celebrate, Toshiba have outed two new mSATA SSDs, offer 30GB and 62GB capacity

Each of the Toshiba mSATA SSDs boasts up to 180MBps sequential read speeds and up to 70MBps sequential write speeds; they also have clever power management tech which reduces consumption to less than half of read power levels when in idle, standby or sleep modes. Toshiba have also released the same modules but in more traditional half-slim SATA II format, which are a little larger (but can at least be used with a desktop SATA II interface, unlike mSATA).

To be honest, while there are size benefits to the new interface – though not huge ones, if you look at the two modules pictured above – we’re not sure whether we’d actually prefer to keep desktop/mobile compatibility instead. Still, time and tides wait for no man, least of all us, so mSATA is likely here to stay.

Seagate Barracuda XT 2TB SATA 6.0Gbps hard-drive is world’s first

Chris Davies — Mon, 21 Sep 2009 14:55:41 +0000

Seagate have announced the world’s first SATA 6Gbps hard-drive, the Barracuda XT, a huge chunk of 2TB capacity aimed at high-performance workstations. The Barracuda XT 2TB spins at 7,200rpm and is the first to feature the faster-speed SATA interface, though it’s also backward compatible with SATA 3.0Gbps and 1.5Gbps.

That’s useful, as right now there’s limited choice for motherboards with 6.0Gbps SATA interfaces. Currently you’re looking at a clutch of models from ASUS and Gigabyte, whom Seagate are seemingly promoting alongside the Barracuda XT. After all, what good is all that performance if you’re not going to take advantage of it.

The drive also has 64MB of cache, and uses four platters in order to squeeze all those bytes inside. Official pricing is expected to come in somewhere around $299.

Press Release:

Seagate Ships World’s Fastest Desktop Hard Drive; First Drive to Feature Serial ATA 6Gbit/Second Technology

Seagate Teams With Technology Leaders to Bring SATA 6Gbit/s Complete Solutions to Market

SCOTTS VALLEY, Calif. – September 21, 2009 -

Seagate Barracuda XT, the world’s fastest desktop hard drive featuring the blazing fast Serial ATA 6Gb/s interface. Seagate Technology (NASDAQ:STX) today began global shipments of the world’s fastest, largest-capacity mainstream desktop hard drive – Barracuda® XT, a 7200RPM product featuring 2TB of storage capacity and a blazing fast Serial ATA (SATA) 6Gb/second interface. The 3.5-inch desktop drive, the industry’s first to feature a SATA 6Gb/s interface, meets the capacity demands of gaming, digital video-environments and other storage-hungry desktop computing applications while delivering the highest performance in its class.
The introduction of the Barracuda XT drive marks the shift to the next generation of desktop computing speed as Seagate doubles the storage bandwidth of current computers.

“Capacity and performance remain the defining attributes of hard drives for PC gamers, digital multimedia content developers and many other customers requiring high-end systems at home and in the office,” said Dave Mosley, executive vice president of Sales and Marketing at Seagate. “Seagate is meeting these requirements with the first 7200RPM desktop hard drive to combine 2TB of storage capacity with the fastest Serial ATA interface to date.”

The Barracuda XT product, a four-platter drive featuring an areal density of 368 Gigabits per square inch, delivers the highest performance – burst speeds of up to 6 Gigabits per second – for all PC applications, maintains backward compatibility with the SATA 3Gb/second and SATA 1.5Gb/second interfaces, and uses the same cables and connectors as previous SATA generations to ease integration. The hard drive’s SATA 6Gb/s interface enables system builders using SATA 6Gb/s drive controllers to build high-performance desktop PCs, full-tilt gaming rigs, and home and small business servers, and its 64MB cache optimizes burst performance and data transfer speeds.

“Marvell is pleased to be announcing the industry’s first commercially available SATA 6Gb/s solution and working with Seagate to introduce this technology,” said Dr. Alan J. Armstrong, vice president of Marketing, Business Storage Group at Marvell. “Marvell has been working with a broad group of partners and customers to bring this solution to market. As early adopters of Marvell’s SATA 6Gb/s technology, both ASUS and GIGABYTE offer motherboards to complement SATA 6Gb/s hard drives.”

The Serial ATA 6Gb/s Solution: Barracuda XT Drives and Motherboards from ASUS and GIGABYTE

With Barracuda XT drives and SATA 6Gb/s motherboards from ASUS and Gigabyte, computer makers can build the highest-performance PCs, workstations and entry-level servers. ASUS was first to market with a SATA 6Gb/s motherboard; the company’s P7P55D Premium began shipping in August. The new GIGABYTE P55 series GA-P55-Extreme motherboards are also now shipping .

“At ASUS, we are once again at the forefront of innovation by being the first to launch a native SATA 6Gb/s interface on a motherboard,” said Joe Hsieh, corporate vice president & general manager, Motherboard Business Unit & Desktop Business Unit, ASUS. “An expansion bridge integrated into the P7P55D Premium helps achieve real SATA 6Gb/s throughput to support bandwidth-hungry applications. The ASUS solution eliminates transmission bottlenecks in current technology and ensures users truly enjoy faster data speeds and double the storage bandwidth. For other P7P55D Series models, ASUS also provides an expansion card to achieve the same results.”

Elecom nanoSSD slots straight into SATA port

Chris Davies — Tue, 25 Aug 2009 09:44:15 +0000

Elecom have announced two new solid-state drives, the 8GB and 16GB nanoSSD ESD-IDSAA Series, which are designed to slot directly into a SATA motherboard slot. Measuring 25 x 39 x 6.5 mm, the nanoSSDs can be used as startup drives on a main system or, Elecom suggest, the primary drive on a compact Mini-ITX setup.

Despite the diminuative scale, the data transfer speeds are still fair. The Elecom SSDs manage 75MB/s read rates and 30MB/s write-rates, and of course there’s no noise and cooling requirements are minimal.

An auxiliary power cable – which gets its juice from a molex pass-through – is also supplied in case the Vcc pin from the SATA port isn’t sufficient to power the nanoSSD. No word on pricing, but pre-orders should apparently already have started in Japan.

ASUS P6X58 Premium motherboard with USB 3.0 and SATA 6Gb/s

Chris Davies — Tue, 21 Jul 2009 08:51:37 +0000

In case you can’t read the helpful legends in the image below, you’re looking eye-to-port at what promises to be the first motherboard with dual SuperSpeed USB 3.0. The ASUS P6X58 Premium is designed for Intel’s Core i7 CPU range, and has six DDR3 memory slots, three PCI Express 2.0 slots and the usual bevy of USB 2.0 ports and headers; however, ASUS have also thrown in a pair of USB 3.0 ports capable of a theoretical 4.8Gbps transfer rate.

There’s also a SATA 6 Gb/s interface, Firewire, optical and coaxial digital audio outputs and the usual 5.1 analog surround sound connectors. ASUS also throw in dual ethernet (likely to be gigabit) and a couple of PS/2 ports for you legacy keyboard lovers out there.

The USB 3.0 ports – which use the NEC µPD720200 host controller - are blue, whereas the standard USB 2.0 ports are black; of course, they’re also backward compatible, so you don’t miss out on any connectivity. No news on release date or pricing for the ASUS P6X58 Premium, nor benchmarking, but we’d expect it to be – as the “premium” name suggests – an expensive ‘board.

MacBook Pro 3.0Gbps SATA upgrade breaking third-party drives?

Chris Davies — Fri, 26 Jun 2009 10:17:46 +0000

The recently-released MacBook Pro firmware that promises to enable 3.0Gbps SATA connectivity has ironically been causing problems in third-party drives. Apple released the upgrade earlier this week, after users of the new 13- and 15-inch MacBook Pro models reported that the notebooks were limited to 1.5Gbps SATA; this did not affect the speed of standard-fit hard-drives, but may have limited future performance should the user upgrade to a faster HDD or SSD. Now, some users with third-party drives already installed are reporting frequent pauses, usage spikes and data errors with the new firmware.

Both traditional hard-drives and solid-state storage are presenting problems. One user found his Western Digital Scorpio Blue HDD now suffers intermittent data errors and that the whole machine freezes randomly. Meanwhile another user who has upgraded to an Intel X25-M SSD found his drive no longer works at all following the firmware update. Some have found that re-installing the original SATA 1.5Gbps drive supplied by Apple restores the machine to working order, while others have had no luck.

Apple distanced themselves from aftermarket upgrades when they first released the firmware, warning users that they had “not qualified or offered these drives for Mac notebooks” and that “their use is unsupported.” That seems to mean they won’t fix the issue under warranty: many who have contacted Apple Stores or technical support regarding the firmware issues have been told that “Apple is not responsible for maintaining compatibility with third-party aftermarket hardware with their firmware updates.” However there is also talk that Apple Store “Geniuses” can roll back the firmware if there was a problem during the upgrade itself, though not otherwise.

Samsung mini-PCIe SSD: up to 64GB of super-compact storage

Chris Davies — Tue, 23 Jun 2009 10:15:48 +0000

Samsung have announced a solid-state drive (SSD) that fits onto a mini-PCIe card, offering up to 64GB capacity in a form-factor nearly 80-percent smaller than a 2.5-inch drive. The SATA 3.0 Gbps drive is not only intended for compact devices, such as MIDs and netbooks, but as a secondary or complementary drive for regular notebooks.

In that way, users would no longer have to choose between the speed of SSD and the low price of traditional hard-drives, but instead have both. The mini-PCIe card weighs up to 8.5g and boasts 200MB/s read rates and 100MB/s write rates.

It also supports full-drive encryption and the usual shock-resistance of an SSD. Samsung are currently sampling the SATA mini-card SSD to its hardware partners, while pushing for standardization on its mechanical form-factor and pin-layout. That’s expected to be completed by Q3 2009; there’s no word on when we could see the drives reach the market.

Press Release:

Samsung Develops Solid State Drive with SATA Mini-card Design

Seoul (Korea Newswire) June 23, 2009 11:17 AM — Samsung Electronics Co., Ltd., the world leader in advanced semiconductor technology, announced today that it is now sampling a SATA-interface mini-card solid state drive (SSD) with some of its customers, for use in the expanding netbook marketplace. The Samsung SATA mini-card SSD expands the use of SSDs from not only being a primary storage medium, but also as a complementary drive to boost the performance of PCs with dual drive capabilities.

Samsung’s new mini-card form factor, with a highly robust interface, makes an already rugged SSD even less susceptible to damage from jarring, jostling and dropping.

“The market is beginning to embrace a smaller SSD for the nascent netbook sector,” said Jim Elliott, vice president, memory marketing, Samsung Semiconductor, Inc. “The cost-efficiency and reliability of lower-density, highly compact Samsung SSDs are perfectly suited as the storage medium for the rapidly growing netbook marketplace,” he added.

Featuring a mini-PCI Express (PCIe) form factor with a SATA 3.0Gb/s interface, the highly cost-efficient mini-card SSD is nearly 80 percent smaller than the conventional 2.5-inch hard disk drive, making it ideal for the tighter constraints of most netbooks. In addition, it can be used in printers and various handheld terminals including ruggedized mobile devices.

Moreover, the SATA mini-card SSD form factor can be used in a combination comprised of the SSD as main memory and HDD as supporting storage space. This new approach is expected to increase the adoption of SSDs in a broader range of applications.

Samsung is working to standardize the new mechanical form factor and its pin layout specifications at JEDEC (Joint Electron Device Engineering Council). With possible revisions by OEM manufacturers, standardization could be expected as early as the third quarter of this year.

Available in 16GB, 32GB and 64GB densities, the new SSD drive will be produced using 40-nanometer-class process technology. The SATA mini-card SSD provides strong performance levels with a sequential read rate of 200MB/s (megabytes per second) and writes data sequentially at 100MB/s.

Samsung’s mini-card SSD is only 30 millimeters (mm) wide and 51mm high. The drive weighs up to 8.5g and measures up to 3.75 millimeters thick. Also offering a high degree of energy efficiency, the new drive consumes 0.3 watts of power.

Samsung’s new netbook-targeted SSD is available with optional full disk encryption to thwart theft or any unwanted access to a netbook or other device.

Apple address slow MacBook Pro SATA with firmware update

Chris Davies — Tue, 23 Jun 2009 08:32:41 +0000

Apple have released a firmware update for their latest MacBook Pro notebooks that fully enables their SATA 3.0 Gbps interface. The move comes in response to vocal complaints from MacBook Pro 13- and 15-inch buyers who discovered Apple had seemingly limited their new unibody machines to the older 1.5 Gbps SATA. However the company has distanced itself from drives that actually use the faster interface, reminding users that “Apple has not qualified or offered these drives for Mac notebooks and their use is unsupported.”

According to users, only those who had ordered the factory-fit SSD option had the faster SATA-II enabled. Those with traditional hard-drives would not have noticed issues with the reduced transfer rate, but had they chosen to upgrade to an SSD at a later date the 1.5 Gbps interface could have presented a bottleneck.

The update itself, “MacBook Pro EFI Firmware Update 1.7″, is a 3.35MB download and requires that the user is running Mac OS X 10.5.7. The company has made no comment on why it chose to limit the new notebooks to the older SATA version.

MacBook Pro 13- and 15-inch limited to SATA not SATA-II?

Chris Davies — Mon, 15 Jun 2009 10:21:49 +0000

MacBook Pro confusion this weekend, as some owners of the new unibody 13- and 15-inch notebooks are reporting that their machines are apparently limited to 1.5Gb/s SATA connections rather than the faster 3.0Gb/s SATA-II. Full details are unclear, but it seems that Apple have either switched to SATA hardware or used firmware for the newest MacBook Pros that limits hard-drive connections to the slower speed.

The move has the most impact on those who upgraded to the SSD option in their new MacBook Pro. Regular hard-drives, which the notebooks are both fitted with as standard, will prove unaffected, as the read/write speeds of the drive are slower than SATA. However SSDs, which can manage higher sustained read rates, are clocking in with lower speeds compared to previous-generation MacBooks and MacBook Pros.

Any impact on real-world performance, however, is unknown. Transferring files to external drives would be limited by the USB/Firewire connection rather than the choice of SATA or SATA-II. It’s possible that a new firmware update could “unlock” the faster connectivity, but so far Apple have not publicly commented.

VIA NSD7200 desktop NAS emerges

Chris Davies — Fri, 03 Apr 2009 11:03:23 +0000

Images of a so-far unannounced VIA NAS have emerged, the VIA NSD7200. A compact desktop unit with three USB ports and what’s likely to be a gigabit ethernet connection, the NSD7200 was promised for launch at the Embedded World 2009 conference back in March, but nothing has been heard regarding it since.

Judging by the model number, the VIA NSD7200 slots in under the NSD7800, a tower-format NAS with room for up to eight 3.5-inch SATA drives. Going by the case similarities, we’re presuming the NSD7200 is similar to the VIA ARTiGO A2000 barebone storage server we reviewed back in February; that has room for two 3.5-inch SATA-II hard-drives, but has more connectivity options than the NSD7200.

Like the NSD7800 and ARTiGO A2000 the VIA NSD7200 probably uses a 1.5GHz C7-D processor with between 1GB and 2GB of RAM. We’re expecting to hear full details from VIA soon, and will update when we know more.

Update: According to VIA, the NSD7200 is an OEM product and will go on sale under another brand(s). It’s apparently available now, but VIA don’t have pricing for any of the third-parties.

AMD & Seagate demo SATA 6Gbps HDD

Chris Davies — Mon, 09 Mar 2009 15:15:59 +0000

Seagate and AMD will be demonstrating the world’s first SATA 6Gbps hard-drive today, theoretically offering twice the throughput of the existing SATA 3Gbps standard. The demo will compare an existing Barracuda 7200.12 HDD and a SATA 6Gbps HDD that uses a prototype AMD chipset to offer 5.5Gigabits per second performance.

The companies are hoping to provoke interest in the new SATA 6Gbps standard, which will begin showing up in hard-drives before the end of 2009. It uses the same cables and connectors as previous 3Gbps and 1.5Gbps SATA, but introduces new power-efficiency technology among other things.

New drives will be backward compatible with motherboards that only support the existing SATA speeds, so we’re hoping to see them hit the market sooner rather than later. No word from Seagate as to when a commercial version of the current prototype will be launched.

Press Release:

Seagate and AMD Unveil World’s First Demonstration of Serial ATA 6Gigabit/Second Technology for High-Speed PC Applications

Seagate (Nasdaq: STX), teaming with microprocessor manufacturing leader Advanced Micro Devices (AMD) at the Everything Channel Xchange Conference in New Orleans this week, today unveiled the world’s first public demonstration of next-generation high-speed data transfer – Serial ATA 6Gigabit/second – for bandwidth-hungry desktop and laptop PC applications including gaming, streaming video and graphics multimedia.

The Serial ATA (SATA) 6Gb/second storage interface will deliver the highest performance – burst speeds of up to 6Gigabits per second – for all PC applications, maintain backward compatibility with the SATA 3Gb/second and SATA 1.5Gb/second interfaces, and use the same cables and connectors as previous SATA generations to ease integration. The third generation of the mainstream storage interface for desktop and notebook computers also enhances power efficiency and improves Native Command Queuing, a SATA feature, to increase overall system performance and data transfer speeds of mainstream PC applications but especially applications with heavily transactional workloads such as scientific modeling and forecasting, and engineering design and simulation.

“The increasing reliance of consumers and businesses worldwide on digital information is giving rise to gaming, digital video and audio, streaming video, graphics and other applications that require even more bandwidth, driving demand for PC interfaces that can carry even more digital content,” said Joan Motsinger, Seagate vice president of Personal Systems Marketing and Strategy. “The SATA 6Gb/second storage interface will meet this demand for higher-bandwidth PCs. Seagate has a long history of being first to market with new technologies such as Serial ATA, perpendicular recording and self-encrypting drives, and is pleased to be teaming with AMD to stage the world’s first public demonstration of SATA 6Gb/second storage.”

“AMD strives to deliver platform technology that our technology partners can use to create high- performance desktop and laptop PCs,” said Leslie Sobon, vice president of Product Marketing, AMD. “The new SATA 6Gb/second technology not only incorporates the best features of previous SATA generations but also includes new enhancements. This innovation enables AMD to continue to evolve its technology platforms and to develop low-cost designs that our technology partners can use to improve their own PC and laptop products.”

The Seagate and AMD demonstration features two Seagate SATA disk drives – one a shipping Barracuda(R) 7200.12 3Gb/second hard drive and the other a prototype Barracuda 6Gb/second drive – in a desktop PC to show the performance difference between the two generations. The PC is powered by an AMD prototype SATA 6Gb/second chipset. The Seagate SATA 3Gb/second drive runs at more than 2.5Gigabits per second and the SATA 6Gb/second drive at 5.5Gigabits per second, with the performance of each storage interface displayed on the PC monitor.

Serial ATA 6Gb/second – Blazing speed for next-generation personal computing

Serial ATA (SATA), the mainstream storage interface for desktop and notebook disk drives, is currently available in two speeds – 3Gb/second and 1.5Gb/second. SATA 6Gb/second was developed by the Serial ATA International Organization (SATA-IO) under the Serial ATA Revision 3.0 specification.

In keeping with SATA-IO objectives for designing a low-cost interface for desktop and notebook PCs, SATA 6Gb/second maintains the low cost and low-power design requirements of previous SATA generations, and is designed to be backward compatible with SATA 3Gb/second connectors, cables and other hardware.
