Robin Harris talks about capacity growth in 2.5″ notebook drives, and wonders what it portends for the enterprise. No doubt that 1 TB ‘mobile’ drives, available from Seagate later this quarter, are interesting. But the enterprise is affected in a way not discussed by StorageMojo.
He’s absolutely right that the enterprise is moving to 2.5″ SAS and SATA. But the 2.5″ notebook device world has little to do with it, other than general learning curve efficiencies in the factory.
That’s because unlike the 3.5″ form factor, 2.5″ ‘mobile’ drives have very little to do with enterprise drives. Even the width of the drives are different. This has lead to a new-to-the-world class of 2.5″ 7200 rpm enterprise drives, since notebook drives won’t ever have what it takes to support enterprise. These new drives come in SAS or SATA (which says a lot, given the idealogical differences between the SAS and SATA disk drive contingents), currently up to 500GB.
It’s rare these days to see a totally new animal in the disk drive world. Seagate’s version is called Constellation. It’s the (till now) missing link for the 2.5″ enterprise form factor to go “all the way”.
