250GB SATA SSD for everyday systems

This 2.5 inch drive uses 3D NAND with an SLC cache to deliver sequential reads up to 500 MB/s and writes up to 420 MB/s. It fits laptops, desktops and ultra-slim notebooks with a 7mm height. The drive replaces a mechanical hard disk for faster boot and application loading.

Sustained random performance

Random 4KB reads hold at 95000 IOPS and writes at 90000 IOPS under continuous workloads rather than brief bursts. A 128 TBW rating and 1.5 million hour MTBF indicate the write endurance expected for typical consumer use. No heatsink is included, so airflow in the chassis manages temperature.

SATA III interface limits

The SATA III 6 Gb/s link caps maximum throughput near the quoted sequential speeds. Compatibility spans Windows 7, 8.1, 10, macOS 10.x and Android 4.4 with OTG. The drive works in most popular PC, laptop and ultrabook platforms without additional drivers.

Questions about this item

How much power does the 250GB SATA III drive draw during all-day operation?

The drive has no moving parts and runs silently, so heat output and power draw stay very low compared with a mechanical hard disk.

Does my laptop need a specific SATA III port or a 7 mm drive bay to fit this 2.5" SSD?

Any standard 2.5" SATA bay works; the 7 mm height fits most laptops, ultrabooks and desktops that accept a 2.5" drive.

Will the SATA III interface limit speed if I keep an older SATA II motherboard?

The drive is backward compatible with SATA II, so it will work but sequential speeds will drop to the older bus limit.
