Gigastone 2-Pack 250GB SATA internal SSD

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.
