1.92TB SATA SSD for mixed workloads

The Samsung SM863a is a 1.92TB internal solid-state drive built on QLC flash with a 2.5-inch SATA 6Gbps interface. It delivers up to 520 MBps sequential read and 485 MBps sequential write speeds. Random performance reaches 97000 IOPS read and 29000 IOPS write. The drive draws 3.45W active power and carries a 2,000,000-hour MTBF rating.

Suits read-heavy servers and content archives

This drive fits read-intensive server roles, media libraries and backup targets where capacity per pound matters and write cycles stay moderate. Heavy transactional databases, high-endurance logging or sustained high-write workloads should look at drives with higher write endurance ratings.

Verify 2.5-inch bay and SATA power

Confirm your chassis has a free 2.5-inch drive bay or a 3.5-inch adapter bracket. Ensure the motherboard or controller provides a SATA 6Gbps port and that your power supply includes a spare SATA power connector. Check BIOS or RAID controller firmware for SSD trim support.

Questions about this item

Will my system need a 2.5" SATA bay and SATA power cable to install the 1.92TB SM863a?

Yes, the drive uses a standard 2.5" form factor and SATA interface, so an available 2.5" drive bay and a SATA power connector from your PSU are required for installation.

Can the 520 MBps sequential read speed of the SM863a be used with an older SATA 3Gbps controller?

The drive supports SATA 6Gbps but is backward compatible with 3Gbps ports; on an older controller the sequential read will be limited to the 3Gbps link speed rather than the rated 520 MBps.

How can I confirm the SM863a is delivering its rated 97000 IOPS random read performance after setup?

Run a 4KB random read benchmark such as CrystalDiskMark or AS SSD and compare the reported IOPS to the 97000 IOPS specification to verify the drive is operating as intended.
