Capacity and interface

This 12TB SAS 12Gb/s hard drive is built for Dell PowerEdge 14 and 15 Generation servers and Dell Tower 15 Generation servers. It suits administrators who need high-capacity bulk storage inside compatible 3.5-inch bays. Buyers who need a different interface or a smaller form factor should look elsewhere.

Upgrade path and fit

The drive replaces lower-capacity SAS drives in the listed R240 through R940xa, R250 through R7525, and T150 through T550 models. The jump is worth it when existing arrays hit space limits and the chassis accepts 3.5-inch SAS devices. Systems without SAS backplanes or with only 2.5-inch bays cannot use this kit.

Sustained workload behaviour

Spinning at 7200 RPM, the drive delivers consistent throughput for sequential workloads such as backup, archiving and video surveillance recording. Random I/O performance follows typical mechanical limits, so databases with heavy random access may benefit from a different storage tier. The SAS 12Gb/s link keeps the pipe full during long write streams.

Questions about this item

Does this 3.5" SAS drive fit a standard 3.5-inch server bay?

Yes, the 3.5-inch form factor matches standard 3.5-inch drive bays in the listed Dell PowerEdge 14G and 15G rack and tower servers.

What is the correct way to install the SAS 12Gb/s drive so the controller detects it?

Insert the drive into a hot-swap bay or caddy, seat the SAS connector firmly until it clicks, then run a controller rescan or reboot so the 12Gb/s link negotiates.

When should I expect to replace this 7200 RPM enterprise drive?

Enterprise 7200 RPM SAS drives are rated for continuous operation; plan replacement after five years or when SMART attributes show reallocated sectors or excessive seek errors.
