HP 146GB 2.5" SAS 15000 RPM Drive
This new HP 652605-B21 is a 2.5-inch internal hard drive with a SAS 6Gb/s interface, 146GB capacity and 15000 RPM spindle speed. It is built for HP server and blade environments that demand high transaction throughput. The 15.6 mm height fits standard enterprise 2.5-inch bays.
Suits servers needing fast SAS storage
This drive suits administrators running high-transaction workloads on compatible HP ProLiant or BladeSystem platforms where hot-plug capability and 15000 RPM performance are required. Buyers whose systems lack a SAS 6Gb/s backplane or who need more than 146GB of capacity should look at other options.
SAS 6Gb/s interface and 15000 RPM speed
The single specification that decides fitment is the SAS 6Gb/s interface combined with a 15000 RPM spindle speed; the host must support SAS signalling and accept a 2.5-inch drive no taller than 15.6 mm. Without a compatible SAS controller and bay, the drive cannot operate.

Questions about this item
Should I choose the 146 GB 15000 RPM SAS drive or a lower speed model?
The 146 GB capacity at 15000 RPM suits high transaction workloads where fast random access matters more than maximum storage space.
What does the 6144 MB/s external transfer rate mean once the drive is installed in a server?
That figure is the SAS 6Gb/s interface ceiling; real world throughput will be lower and depends on the controller, queue depth and the mix of read and write operations.
The drive uses a SAS 6Gb/s interface — what does that cap in practice?
The 6Gb/s link limits the maximum external data rate to 6144 MB/s, and the drive is hot pluggable in compatible HP ProLiant and BladeSystem bays.
