Frequently Asked Questions

Does the 8TB SN850X actually hit 7,300 MB/s?

The 7,300 MB/s read and 6,300 MB/s write ratings are the SN850X line's peak figures, and Sandisk specifies the 7,300 MB/s read number for the 1TB-4TB models. Check the manufacturer's spec sheet for the 8TB model's rated sequentials before buying on speed alone.

Will this fit my PS5 or laptop?

It is a standard M.2 2280 NVMe drive, so it fits any slot that accepts that length. Confirm your system supports 8TB NVMe drives and, for consoles, check the current firmware's supported capacity list - the product listing does not state console certification.

Do I need a heatsink for this drive?

The 8TB model is not offered in the optional heatsink version - that is limited to the 1TB and 2TB drives. The SN850X includes Adaptive Thermal Management to manage sustained load, and most modern motherboards ship with an M.2 heatsink you can use.

What kind of NAND does it use, and does that matter?

It uses Sandisk TLC 3D NAND, which stores three bits per cell. TLC generally sustains higher write speeds and endurance than the QLC NAND common in other high-capacity drives, which matters if you move large video or game files regularly.

Is the RGB lighting and monitoring software available on Mac?

No. The WD_BLACK Dashboard, which handles drive health monitoring, RGB customization, and Game Mode 2.0, is Windows only. The drive itself works in any system with a compatible M.2 slot, you just lose the software features.
