Server-Class 300GB SAS Drive
This IBM 42D0637 is a 300GB 2.5" internal hard drive spinning at 10000 RPM with a SAS 6Gb/s interface and 16MB cache. It is built for server environments where consistent throughput and hot-swap capability matter. The drive arrives new in retail or OEM packaging.
Suits High-IO Server Bays
The 10000 RPM spindle and 2.9ms average seek time serve workloads that demand quick random access, such as transactional databases or virtualisation hosts. The SAS 6Gb/s link and hot-swap support fit directly into compatible enterprise backplanes. Buyers needing a different capacity or a non-SAS interface should consider other options.
Deciding Spec Is SAS 6Gb/s Interface
The single specification that decides fitment is the SAS 6Gb/s interface; the drive will only operate in controllers and backplanes that support this protocol. Verify that your server or storage array accepts 2.5" SAS drives before purchase.

Questions about this item
Does my system need a SAS 6Gb/s backplane or controller for the 42D0637 to operate?
Yes, the drive uses a SAS 6Gb/s interface and requires a compatible SAS controller or backplane that supports 6 Gb/s signalling.
Can the 2.5 inch 10000 RPM drive share a SAS expander with older 3 Gb/s SAS disks?
The 42D0637 will negotiate down to 3 Gb/s on a shared expander, so it works alongside legacy SAS drives at the slower link speed.
How can I confirm the 42D0637 is running at its rated 10000 RPM and 2.9 ms seek time after installation?
Check the drive’s SMART data or controller BIOS; they report spindle speed and seek-performance metrics that should match the 10000 RPM and 2.9 ms specifications.
