Our take on the HP E 857648-B21 10TB 3.5' SATA 7200rpm Internal Hard Drive

This is HP's 10TB enterprise 3.5-inch SATA hard drive, a 7200 rpm helium-class drive built for servers and storage arrays rather than desktops. It uses the SATA 6Gb/s interface, so it drops into any standard SATA bay without a RAID controller. The draw is capacity per bay: 10TB from one 3.5-inch slot at 7200 rpm, which beats 4TB and 6TB drives on density but trails 7200 rpm NAS drives from Seagate and Western Digital on retail availability and warranty terms. It suits server builds, backup targets and bulk media storage; desktop buyers are usually better served by a cheaper consumer drive.

Pros
  • 10TB in a single 3.5-inch bay
  • 7200 rpm spindle for faster sequential reads than 5400 rpm drives
  • Standard SATA 6Gb/s interface, no special controller needed
  • HP part number makes it easy to match an existing server build
  • Enterprise-oriented design for 24/7 operation
Cons
  • Louder and hotter than 5400 rpm and helium consumer drives
  • No retail warranty paperwork; support runs through HP channels
  • Overkill and costly for a single desktop
  • Not a NAS-specific drive, so RAID rebuild behavior varies
  • SATA only, no SAS option in this part number

Questions and answers

Will this drive work in a regular desktop PC?
Yes. It uses standard SATA 6Gb/s and a 3.5-inch bay, so any desktop with a free SATA port and power connector can run it. Expect more noise and heat than a consumer drive.
Is it good for a NAS?
It works in a NAS, but it is not a NAS-specific drive. Vibration and RAID rebuild behavior vary, so check your NAS vendor's compatibility list before buying several.
What is the difference from a 5400 rpm drive?
The 7200 rpm spindle gives faster sequential reads and writes, which helps large file transfers and backups. It also means more noise and power draw.
Does it need a RAID controller?
No. It connects to any SATA port. A RAID card only matters if you want hardware RAID or more ports.
What comes in the box?
The drive itself. SATA cables, screws and drive trays are not included, so have those ready for a new build.
Is it compatible with HP ProLiant servers?
The part number is an HP server spare, so it is intended for ProLiant and similar HP systems. Confirm your model's drive carrier and firmware support first.
Where is the HP E 857648-B21 10TB 3.5' SATA 7200rpm Internal Hard Drive cheapest?
