Two-drive 250GB SATA kit

This pack contains two 2.5 inch internal solid state drives, each offering 250GB of storage. They are built with 3D NAND flash and connect through a SATA III interface. The drives suit desktops, laptops and ultra-slim notebooks that accept a 7mm height drive. They serve as a direct replacement for mechanical hard disks in everyday computing.

SATA III throughput ceiling

The SATA III link caps sequential transfer at 6Gb/s, so the drives deliver up to 500 MBps read and 420 MBps write. Random 4KB performance reaches 95000 read IOPS and 90000 write IOPS. These figures represent the practical limit of the SATA interface, not the flash itself. System overhead and file-size mix will reduce real-world rates.

128TB write endurance per drive

Each drive is rated for 128TB of total bytes written and a 1.5 million hour MTBF. That endurance figure is the key metric for deciding whether the SSD matches your workload. Light client use will consume only a fraction of this budget, while heavy write tasks such as video capture or database logging will approach it faster.

Questions about this item

Should I buy the 2-pack or a single drive for my laptop upgrade?

This listing is a 2-pack of 250GB drives, giving you 500GB total across two separate 2.5" SATA SSDs for use in two machines or a RAID setup.

Will I actually see 500 MB/s read speed in my older laptop?

The drive reaches up to 500 MB/s sequential read and 420 MB/s write on a SATA III 6Gb/s port; real-world speeds depend on your system's SATA controller and workload.

Does the SATA III interface limit performance compared to newer standards?

SATA III caps at 6Gb/s, so this 3D NAND SSD delivers up to 500 MB/s read and 420 MB/s write, which is the practical ceiling for the interface.
