960 GB SATA enterprise SSD

The HPE P18424-B21 is a 960 GB solid-state drive built for read-intensive server workloads. It connects through a 6 Gbit/s SATA interface in a 2.5-inch small-form-factor package. The drive is rated for 0.8 drive writes per day and 1,400 lifetime writes, making it suited to workloads that read far more often than they write. It is designed for hot-plug installation in supported HPE ProLiant platforms.

Read-heavy server workloads

This SSD fits databases, content delivery, virtual desktop infrastructure and boot volumes where sustained read throughput matters more than write endurance. Its 0.8 DWPD rating means it is not intended for write-heavy applications such as high-frequency logging, OLTP databases with heavy commit rates or video ingest pipelines. Teams needing higher write endurance should consider drives with a larger DWPD figure.

Steady-state read performance

Under sustained load the drive delivers up to 58,500 random read IOPS at queue depth 32 and 29,000 random write IOPS at queue depth 4. Random read IOPS at queue depth 16 reach 58,500 while random write IOPS at the same depth reach 29,000. Power draw is specified at 6 watts during operation.

Questions about this item

What server platform must I already have to install the HPE P18424-B21?

The drive is qualified for HPE ProLiant Rack, Tower, BladeSystem and Synergy servers with a 2.5-inch SATA hot-plug bay.

Will the P18424-B21 work in a legacy 3 Gb/s SATA backplane?

Yes, the SATA 6 Gb/s interface negotiates down to 3 Gb/s, so it will operate on older backplanes at the lower link speed.

How can I verify the drive is delivering its rated 58,500 random read IOPS after setup?

Run a 4 KiB random read test at queue depth 32 using a tool such as fio or Iometer and compare the result to the 58,500 IOPS specification.
