HP 653122-B21 3.5" 100GB SATA enterprise SSD

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.
