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.

2TB lost to parity, and nobody bats an eyelash.

I remember when I had to get a 120MB HDD to get 100MB of actual storage. Wasn't all that long ago (to me anyway). Wow. I feel old now.

When you remember 8" floppies, storing programs on casette tapes, and editorials claiming that 64 Kbytes (not MBytes or GB) of RAM was all computers would ever need....then you can feel old :)

Actually it was Bill himself saying that 640KB would be enough for a PC :)

No, I'm talking about an editorial in DDJ that was actually *angry* in tone over PCs with 64K (not 640K) RAM. The statement was made that all possible programs could be written smaller than that, so that more memory would just encourage "code bloat".

I don't recall the author...but I wonder what he'd think of some of today's programs.
