200 GB SAS enterprise SSD

The HP 741138-B21 is a 2.5-inch solid-state drive built for server and storage arrays. It uses a SAS 12Gb/s interface and MLC flash to deliver consistent low-latency performance. The drive fits standard SFF bays and draws less power than rotating media.

Suits write-heavy workloads.

This drive targets mainstream-endurance tasks such as databases, virtualization and logging where steady IOPS matter. Buyers who need more storage per bay or a lower cost per gigabyte should consider higher-capacity alternatives.

200 GB capacity decides fit

The usable space is 200 GB, which determines whether the drive can hold the intended dataset or application working set. Verify that this capacity meets the volume requirement before purchase.

Questions about this item

Does my server need a SAS 12Gb/s backplane or controller for this 741138-B21 drive to function?

Yes, the drive uses a SAS 12Gb/s interface and requires a compatible controller or backplane that supports that speed for operation.

Can I mix this 2.5-inch 200GB SAS drive with older 6Gb/s SAS drives in the same array?

The drive will negotiate down to 6Gb/s when connected to a 6Gb/s backplane, but the array will run at the slower speed of the oldest member.

After installation, how can I verify the 741138-B21 is running at its full 12Gb/s link speed?

Check the controller BIOS or management utility; it should report a negotiated link speed of 12Gb/s for this drive.
