Frequently Asked Questions

How fast is the SanDisk Ultra 3D 1TB SSD?

SanDisk rates it at up to 560 MB/s sequential read and up to 530 MB/s sequential write, based on internal testing. Real speeds vary with drive capacity, host device, OS, and application.

Will this SSD fit my laptop?

It is a 2.5-inch drive with a 7mm z-height, which fits standard 2.5-inch laptop and desktop bays. Confirm your machine has a 2.5-inch SATA bay rather than M.2 only before ordering.

What warranty does SanDisk offer on this drive?

The US 1TB model carries a limited 5-year manufacturer warranty or 400TBW, whichever comes first. Check the official SanDisk website for warranty terms in your region.

Is this an NVMe drive?

No. It uses the SATA III 6 Gb/s interface in a 2.5-inch form factor, not M.2 NVMe, so it connects with a SATA data cable and power connector.

Is it good for gaming?

Yes for load times versus a hard drive - SanDisk positions it for faster boot-up and gaming and graphics work. Games load at SATA speeds, so an NVMe drive will be quicker on a board that supports one.
