Drive identity

This 2.5 inch SATA internal SSD delivers 480GB of TLC storage for consumer desktops and laptops. The Marvell 88SS1074 controller provides sequential speeds up to 550 MBps read and 500 MBps write with random performance of 90000 IOPS read and 35000 IOPS write. Rated MTBF reaches 1000000 hours.

Deciding spec

The SATA III interface and 2.5 inch form factor determine whether this drive fits your system; it requires a standard SATA data and power connection and a 7.00mm drive bay. Sequential throughput peaks at 550 MBps read and 500 MBps write, well above a 7200 RPM hard drive. Power draw stays below 2.515W maximum write.

Install notes

The bundle kit includes hardware for straightforward mounting in a 69.85mm by 100.00mm bay. Connect the SATA data and power cables, secure the drive with the supplied screws, and initialise in the operating system. Common issues are loose cables or forgetting to enable AHCI mode in BIOS for full performance.

Questions about this item

What does the 550 MBps sequential read figure mean for everyday use?

It means the drive can read large files such as videos or backups at up to 550 MBps, which is roughly ten times the throughput of a typical 7200 RPM hard drive.

What does the SATA III interface limit in practice?

The SATA III link caps real-world throughput at about 550 MBps read and 500 MBps write, so the drive cannot exceed those speeds even if the controller could go faster.

Will this 2.5 inch drive fit my laptop or desktop bay?

Yes, it measures 100.00 mm long, 69.85 mm wide and 7.00 mm high, matching the standard 2.5 inch form factor used in most laptops and desktop drive cages.
