Enterprise SATA SSD for Servers

The Samsung SM863a is a 960GB 2.5-inch internal solid-state drive built for read-intensive enterprise workloads. It connects through a standard SATA 6Gbps interface and fits any desktop, laptop or server bay that accepts a 2.5-inch SATA drive.

SATA 6Gbps Interface Limits

Sequential throughput reaches up to 510 MBps read and 485 MBps write, while random performance delivers up to 95,000 IOPS read and 25,000 IOPS write. The SATA bus caps maximum bandwidth, so sustained transfers cannot exceed the interface ceiling.

Metal Case and Low Power Draw

A metal enclosure protects the NAND and controller in vibration-prone chassis, and the drive draws 3.45W active power for cooler operation in dense arrays. The 2,000,000-hour MTBF rating reflects the endurance target for continuous server deployment.

Questions about this item

Which capacity of the SM863a should I pick?

The drive is supplied in a 960 GB capacity; choose it when you need near-terabyte storage in a 2.5 inch SATA form factor.

What do the 510 MBps read and 485 MBps write figures mean once the drive is installed?

They are the maximum sequential speeds the controller can deliver, so large file copies and boot sequences will run at up to those rates.

What does the SATA 6 Gbps interface cap in practice?

The SATA link sets the upper bandwidth boundary, and the SM863a reaches 510 MBps read and 485 MBps write within that limit.
