I think the chassis costs about the same, if not cheaper, than Dell or HP. I just bought a 2.5" 5400 rpm 1TB drive from Fry's for $90 last Tuesday. So yeah, its more $/TB/drive , since a 3.5" 1TB drive at the same rpm costs about $70. But I got 2 more spindles per machine compared to a 4-drive unit, so its 50% better I/O perf (both xfer rate and disk-ops) for about $220 more ( = 2 x $90 + 4 x ($90 - $70)) more. > > > > Date: Sat, 6 Nov 2010 07:25:04 -0700 > > Subject: Re: Where do you get your hardware? > > From: [email protected] > > To: [email protected] > > > > Supermicro also sells 4 nodes in a 2U, with 24 2.5" drives.
