In the world of storage, there are natural tradeoffs. Usually, you'll trade a bit of capacity for size, or perhaps size for speed. HGST
, which presently sits under the Western Digital umbrella, is pushing the enterprise
boundaries a bit with the world's highest capacity 10K RPM hard drive in the 2.5-inch form factor. Designed for compact server use and mission critical applications, the new drive holds a staggering 1.8TB of information (with smaller sizes available if you aren't willing to pony up for the flagship).
The Ultrastar C10K1800 holds 50% more than prior generations of the same drive family, 2.5x better random write performance, and 23% faster sequential performance over prior generation 2.5-inch SFF 10K RPM HDDs. The C10K1800 is also the industry’s first 10K RPM drive to leverage a 12Gb/s SAS interface, which enables rapid transfer rates between host and drive. Advanced format models enable the industry’s highest 10K RPM capacity at 1.8TB with 4K native and 512 emulation to support new systems, and also offers 512 native format models to support legacy systems.
As with most enterprise drives, pricing isn't being shared at the moment, but you'll certainly need a corporate account to afford one.
