960GB SAS enterprise SSD

This HPE 2.5-inch drive delivers 960GB of mixed-use solid-state storage over a 12Gb/s SAS link. It targets servers handling big data analytics, cloud workloads, high-performance compute, databases and virtualization where read and write demands are balanced.

Fits 2.5-inch SFF bays with SAS backplanes

The small-form-factor design slides into standard 2.5-inch drive cages and connects directly to 12Gb/s SAS controllers or expanders. Full data-path error detection and surprise power-loss protection preserve data integrity without extra host software. The drive is also compatible with upcoming 24Gb/s SAS infrastructure for future controller upgrades.

Sustained mixed-use endurance at 3 DWPD

Rated at three drive writes per day, the SSD maintains consistent IOPS and low latency during extended database scans, analytics jobs or virtualization workloads. Enterprise-grade firmware manages wear levelling and garbage collection so performance does not collapse after the initial burst.

Questions about this item

How many full drive writes per day can the 960GB SAS 12Gb/s SSD sustain before endurance becomes the limiting factor?

The drive is rated for 3 DWPD, meaning it can withstand three complete 960GB writes every day over its warranted life.

What thermal or acoustic impact should I expect when the 2.5" SAS SSD runs continuously in a server chassis?

With no moving parts, the SSD produces negligible noise and its steady-state power draw stays low, so standard server airflow handles the heat without extra cooling.

Which controller or backplane must already be in the server for this 12Gb/s SAS drive to operate?

A 12Gb SAS HBA, RAID controller or backplane with a 2.5" SAS bay is required; the drive also works on 24G SAS controllers but will run at 12Gb/s.
