Iomega StorCenter ix2 NAS Review – 1TB Edition

Iomega StorCenter ix2 NAS Review – 1TB Edition

Backup isn't generally seen as glamorous, and the Iomega StorCenter ix2 is unlikely to change that perception. A sober gray box, the ix2 is as compact as dual 3.5-inch SATA-II hard-drives will let it be. However inside there lurks an iTunes-compatible media server, printer sharing facility and optional CCTV recording and Bluetooth file transfers, all for a competitive entry price. Can the StorCenter ix2's hidden charms change our mind about the unbearable dullness of archiving?

Quantenna 1Gbps WiFi chipset promised for 2009

Quantenna 1Gbps WiFi chipset promised for 2009

Startup wireless networking firm Quantenna are claiming to be able to dramatically increase WiFi throughput and signal coverage with their upcoming range of draft-N chips.  Taking advantage of existing aspects of the 802.11n specification that, the company suggests, are currently being under-appreciated, the Quantenna approach is to use multiple concurrent radio channels.  These can either double up on data transmission, increasing reliability and range, or be used discretely to layer transmissions up to the quoted 1Gbps rate.

Linksys WRT610N router for simultaneous dual-band WiFi N

Linksys have released their latest WiFi router, the WRT610N, the claim to fame of which is its ability to simultaneously maintain WiFi band-N connections on both 2.4GHz and 5GHz.  The benefit is in being able to use each band for separate, bandwidth intensive applications; 5GHz has a shorter range but higher throughput, while 2.4GHz is backward compatible with earlier WiFi versions that would usually slow the whole network down.
