Enterprise disk buying guide - Seagate

Learn about the enterprise disks offered by Seagate in the first of a series of buyers' guides to disk.

Hard disks may be unglamorous and are widely assumed to be an endangered species, as solid-state technology asserts itself.

But in recognition of the fact that spinning disks coated in magnetic goop remains the dominant way to store data, SearchStorage ANZ has started to compile a listing of the enterprise disks on sale in Australia and New Zealand today.

In this, the first instalment, of this guide, we consider Seagate products.

We're starting with Seagate because Gartner's most recent analysis of the disk drive market, "Market Share: Granular Shipment Analysis, Hard Disk Drives, Worldwide, 1Q08-4Q08", places the company as runaway leader in the disk drive market with 63.8% of the market and revenue exceeding $US3 billion.

So ... what does Seagate have on offer?

We've listed their drives below. But if you'd like to access the data in an easier-to-manipulate formate, we've also popped it into a Google spreadsheet that you an access by clicking here.
