HGST And WD Launch World’s Largest 10K RPM 2.5-inch Hard Drive At 1.8TB
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.
