Samsung PM863 960 GB SATA enterprise SSD

This Samsung Data Center PM863 drive delivers 960 GB of MLC flash storage in a 2.5-inch SATA III form factor. It is built for servers and storage arrays that need consistent read performance and enterprise-grade endurance. The SFF-8223 controller manages sequential reads up to 525 MBps and sequential writes up to 475 MBps.

Suited for read-heavy server tiers.

The drive fits read-oriented workloads such as web serving, content delivery or virtual desktop infrastructure where random reads reach 99,000 IOPS. It is not a fit for workloads that demand sustained high random write IOPS beyond 18,000 or that require a PCIe interface for lower latency. Buyers needing higher write throughput or a different protocol should consider other models.

SATA III interface caps throughput at 525 MBps read

The single specification that decides fit is the SATA III link, which limits maximum sequential read to 525 MBps and sequential write to 475 MBps. If your application can saturate this bandwidth or needs the higher queue depth of a PCIe interface, this drive will become the bottleneck. Verify that your backplane and controller support SATA III before purchasing.

Questions about this item

Should I pick the 960GB PM863 or look for a larger capacity in this series?

The PM863 series is listed here with a 960GB capacity using MLC NAND; if you need more space you would have to select a different model or series.

What does the 525 MBps sequential read figure mean for my server workload?

Up to 525 MBps sequential read and 475 MBps sequential write are the peak rates the controller can sustain on the SATA III link; real-world throughput will depend on queue depth and the host controller.

How does the SATA III interface limit this drive in practice?

The drive uses a SATA III interface rated at 6 Gbps, so maximum sequential speeds are bounded by that link; the drive delivers up to 99,000 random read IOPS and 18,000 random write IOPS within that constraint.
