High density RAID takes on a whole new definition

Unknown to few outside of the high-density storage industry, 2.5" drives began to overtake several enterprise markets almost overnight with the advent of perpendicular recording.  The high densities, low costs and low power requirements for 2.5" drives make the drives perfect for corporate environments where reliability and density are the focus.

At Computex Taipei, DailyTech got a nice shot of a standard PC tower with fifty Fujitsu 200GB 2.5" drives in a RAID configuration.  The total storage of the array is 10TB, but 2TB are lost to parity for the array. The MHV2200BT hard drives featured in the array, announced by Fujitsu in March of this year, use SATA 1.5Gbps and a mere 4200RPM rotation speed.  Each drive has a peak power usage of 1.6W during a read/write operation, giving the whole array a peak power usage of just 80W.

Furthermore, each drive can be hot swapped in the event of a failure, and Fujitsu representatives had no problem removing drives during the live demonstration.  Fujitsu employees had no estimate on price of such a setup, but the MHV2200BT hard drives are expected to ship this summer.

Earlier this year, Fujitsu employees gave DailyTech the scoop on the migration of the enterprise market from 3.5" drives to 2.5",  and the company is already forcasting 1.8" drives to start packing a punch in the high density market.   Fujitsu already holds the world commercial storage record of 1.3PB.

custom cooling

by using all the front bays there are no front fans blowing on the hdd's??

probably just have a custom cooling device behind the array; 2x120mm fans should do it?

couldnt you also arrange to use 3.5" drives in a 5.25 bay by placing the drives vertically; eg. 4 3.5" drives vertically takes 2 5.25 bays?

using the 750gb drives, wouldnt you get a better performance/reliability setup?

The article states 80W maximum power consumption for the whole array. With that low of power density, it is possible that they could get away with having no fans at all.

Ditto. from my experience no 2.5@ drive needs fans, they simply don't get that hot.
