Ten silver 2.5 inch SAS hard drives in black Dell caddies

DELL

DELL 4X1DR WD9001BKHG 900GB 10000RPM 6Gb/s 2.5" SAS internal hard drive

SKU CH-T7W5-QAB70

Ten enterprise 2.5" SAS hard drives at 900 GB each, 10000 RPM with 32 MB cache and included caddies

  • 900 GB capacity stores large enterprise datasets
  • 10 000 RPM spindle delivers fast transactional response
  • SAS 6 Gb/s interface moves data at enterprise speed
  • 32 MB cache buffers bursts for smoother throughput
  • 5 inch form factor with included caddy fits dense server bays

Dell 900 GB 10 000 RPM SAS Drive

This Dell enterprise hard drive provides 900 GB of storage on a 2.5 inch SAS interface running at 6 Gb/s. The spindle rotates at 10 000 RPM with a 32 MB buffer. Each unit ships new and includes an R Series caddy for direct mounting in compatible Dell servers.

Ideal for Server Storage Arrays

The drive suits administrators expanding capacity in Dell PowerEdge systems that accept 2.5 inch SAS disks. Buyers who need larger single volumes or solid-state latency should evaluate other options because this model is limited to 900 GB and mechanical latency.

Straightforward Hot-Plug Installation

The supplied caddy aligns with Dell hot-plug backplanes so the drive slides in without tools or cables. Ensure the controller supports 6 Gb/s SAS and that the firmware recognises the WD9001BKHG model; mismatched firmware is the most common cause of the drive not appearing during POST.

Questions about this item

Does this drive need a SAS controller or backplane that supports 6Gb/s to operate?

Yes, the drive uses a 2.5in SAS 6Gb/s interface and requires a compatible SAS HBA, RAID controller or backplane that can negotiate a 6Gb/s link.

Will the included R Series caddy fit in a Dell PowerEdge server that currently uses 3.5in drive bays?

The caddy is built for 2.5in R Series bays; it will not mount directly in a 3.5in bay without a separate 3.5in-to-2.5in adapter bracket.

After installation, how can I confirm the drive is running at its rated 10000RPM and 6Gb/s link speed?

Check the controller BIOS or OS utility (for example, smartctl or the RAID management tool) — it should report a negotiated 6Gb/s link and a rotational speed of 10000RPM.
