HP 100 GB SATA II Enterprise SSD

The HP 653122-B21 is a 3.5-inch enterprise solid-state drive with a 100 GB capacity and a SATA II interface. It uses MLC NAND flash and fits a standard LFF hot-swap carrier for HP ProLiant servers. Sequential reads reach up to 257 MBps while writes reach up to 129 MBps. Random 4 KB performance delivers up to 32,000 read IOPS and 6,000 write IOPS.

Suited for read-heavy server workloads

This drive targets mainstream enterprise applications such as boot volumes, local caching or read-intensive databases where low latency and consistent random reads matter. The MLC endurance profile and 7 W idle power suit always-on server environments. Builders needing higher write endurance, larger capacities or a 6 Gbps SATA link should consider other options.

SATA II 3 Gbps interface

The drive connects through a SATA II port limited to 3 Gbps throughput, which caps maximum sequential transfer rates below modern SATA III speeds. Verify that your server backplane or controller supports this generation before installation.

Questions about this item

How much power does the 653122-B21 draw at idle and what is its operating temperature range?

The drive idles at 7W and is rated for 0°C to 60°C, so it stays cool and quiet inside a server chassis all day.

Does this 3.5-inch SATA II SSD need a hot-swap bay or a specific carrier to install in my ProLiant?

It ships with an HP SmartDrive carrier and fits a standard 3.5-inch hot-swap LFF bay; no extra caddy or adapter is required.

Will the SATA II interface on this 100GB MLC drive bottleneck my older RAID controller?

The 3Gb/s SATA II link caps sequential throughput at 257 MB/s read and 129 MB/s write, which matches legacy controllers without wasting their bandwidth.
