Seagate has rolled out a new line of hard drives for network attached storage applications or NAS. There are multiple HDDs in the new family and the highest capacity drive is an 8TB unit. That 8TB HDD is the first of its capacity in the industry that is targeted at small and medium business and home use in NAS units with 1-8 bays.
The HDD is a standard 3.5-inch form factor drive that uses six perpendicular magnetic recording platters. Each of the platters inside the drive has 1.33TB of storage capacity. Those platters spin at 7,200 rpm and the drive has a 256MB DRAM cache.
All of the drives in the series connect with a SATA interface and promise 216 MB/s maximum sustainable media to cache transfer rate. Seagate says that is much faster than previous drives for the same application.
Power consumption for the drives is on average 9W with an average idle power consumption of 7.2W. In addition to the 8TB capacity HDD, the series also has 6TB, 4TB, 3TB, 2TB, and 1TB offerings. Only the 8TB and 6TB drives have 7,200 rpm speed, all others are 5,400 rpm drives. All of the drives have a mean time between failure rating of 1,000,000 hours. The 8TB drive will sell for $385 and will ship later this quarter.
