Manufacturer description

The Bliksem KD650 is a 512GB 2.5-inch SATA III internal SSD built around 3D NAND TLC flash, aimed at anyone upgrading an aging laptop or desktop still running a mechanical hard drive. Bliksem rates it at up to 550 MB/s sequential read and 450 MB/s sequential write over the SATA III 6Gb/s interface, which is close to the practical ceiling of the SATA bus, so boot times, application launches and file copies all tighten up noticeably compared to a spinning disk. The 7mm (0.28 in) 2.5-inch form factor is the standard drive bay size, so it drops into most notebooks, desktops and external…

Frequently Asked Questions

How fast is the Bliksem KD650 512GB SSD?

Bliksem rates it at up to 550 MB/s sequential read and 450 MB/s sequential write over SATA III 6Gb/s. The company notes real speeds vary with capacity, test platform, software and operating system.

Will this SSD fit my laptop?

It uses the standard 2.5-inch, 7mm (0.28 in) form factor with a SATA III 6Gb/s connector, which Bliksem says is compatible with most desktop and laptop computers. Confirm your machine has a 2.5-inch SATA bay rather than M.2 only.

What warranty does Bliksem offer on the KD650?

Bliksem lists a three-year warranty on this drive. Check the product listing for the current terms and claim process before you buy.

Why does my computer show less than 512GB of space?

Bliksem rates capacity in decimal units (1GB = 1000MB) while Windows and most operating systems report in binary units (1GB = 1024MB), so the formatted capacity your OS displays is smaller than the labeled 512GB.

What capacities does the KD650 come in?

The KD650 line is sold in 128GB, 256GB, 512GB, 1TB and 2TB. This listing is the 512GB model in black, priced around the mid-range of the family.
