HP Enterprise 146GB 10000 RPM SAS Drive
This HP Enterprise 507125-B21 is a 2.5-inch Small Form Factor internal hard drive built for enterprise laptops and servers. It delivers 146GB of storage on a SAS 6Gb/s interface with a 10000 RPM spindle speed and a 4ms average seek time.
Suits SAS-Compatible Enterprise Systems
It fits 2.5-inch SFF bays that support SAS 6Gb/s signalling and benefit from high spindle speeds for transactional workloads. It is not for systems that lack a SAS controller or that require a larger capacity than 146GB.
SAS 6Gb/s Interface Decides Compatibility
The drive communicates exclusively over a Serial Attached SCSI 6Gb/s link, so the host must provide a matching SAS backplane or controller. Without that interface the drive will not function.

Questions about this item
Does the 2.5" SFF form factor fit a standard 2.5" drive bay or caddy?
Yes, the 2.5" SFF form factor matches standard 2.5-inch drive bays and caddies used in compatible HP servers and enclosures.
What is the correct SAS backplane insertion procedure for the 507125-B21?
Align the SAS connector with the backplane port and press firmly until the drive clicks into the latch; the common error is stopping before the latch engages.
When should the 146GB 10000 RPM drive be replaced in a 24×7 array?
Replace the drive when SMART attributes report reallocated sectors or when the array controller flags a predictive failure alert.
