Enterprise SAS Drive

The HGST Ultrastar C10K1800 is a 600GB 2.5-inch enterprise hard drive spinning at 10520 RPM with a SAS 12Gb/s interface and 128MB cache. It is built for high-transaction servers and storage arrays that demand consistent low-latency performance.

Compatibility Check

Verify your system has a SAS 12Gb/s backplane or controller and a 2.5-inch bay that accepts a 15mm drive height. The drive uses advance format with 512e sector emulation, so confirm your RAID controller and operating system support this format.

Target Users

Suits administrators upgrading 10K SAS fleets who need 600GB capacity and 23% faster sequential throughput. Not for buyers who want more storage per drive, builders who need a second card, or anyone without a SAS host bus adapter.

Questions about this item

Does the bare-drive package include a mounting tray or SAS cable, or must those be purchased separately?

The drive ships as a bare unit only; a 15 mm 2.5" tray and a SAS 12Gb/s cable are not included and must be sourced separately.

Which capacity and sector-size option suits a 600 GB 512e enterprise array?

The 600 GB model with 512e formatting matches that requirement; the 1.8 TB variant is a different capacity point.

What does the 10520 RPM rating translate to in average latency and seek time once installed?

Average latency is 2.85 ms with average seek times of 3.3–3.5 ms read and 3.8–4.2 ms write.
