960GB SATA III Internal SSD for System Upgrade

The Silicon Power Slim S55 is a 2.5 inch internal solid state drive with 960GB capacity. It connects via SATA III and uses TLC memory components. The drive targets consumers who want faster boot times and application loading compared to a mechanical hard drive.

Easy 2.5 Inch Installation With SATA Cables

Fitting the drive requires a standard 2.5 inch bay or bracket and two SATA cables for data and power. The 7mm height suits most laptop and desktop cages. Common issues include forgetting to initialise the disk in the operating system or using an older SATA II port that limits throughput.

Check SATA Port Availability And OS Support

Verify that your motherboard or laptop has a free SATA III 6Gbps port and a spare power connector from the power supply. Ensure the operating system supports AHCI mode for best performance. Confirm the physical bay can accept a 7mm high drive before ordering.

Questions about this item

How can I verify the drive is delivering the quoted 510 MB/s read and 450 MB/s write speeds after installation?

Run a benchmark tool such as CrystalDiskMark or AS SSD on the SATA III port and confirm sequential results reach the stated 510 MB/s read and 450 MB/s write figures.

What ships with the SP960GBSS3S55S25 and what must I supply myself?

The package contains the 960 GB 2.5-inch SATA III SSD only; you must provide a SATA data cable, a SATA power connection and a 7 mm drive bay or bracket.

Which capacity version of the Slim S55 series should I choose for a primary OS and applications drive?

The 960 GB model gives ample room for the operating system, programs and frequent data while matching the 510 MB/s read and 450 MB/s write ratings of the series.
