Frequently Asked Questions

How fast is the Samsung 870 EVO 4TB?

It reaches 560 MB/s sequential read and 530 MB/s sequential write, which is the practical limit of the SATA III interface. A larger variable write buffer helps it hold high speeds through long transfers instead of dropping off partway.

Will this SSD work in my NAS or laptop?

Samsung compatibility-tested the 870 EVO against major chipsets, motherboards, NAS units, and video recording devices. It uses the standard 2.5-inch SATA III form factor, so any bay and SATA data/power connection will accept it.

How long will a 4TB 870 EVO last before it wears out?

The 870 EVO line is rated for up to 2,400 TBW (terabytes written). At that rating you could write hundreds of gigabytes a day for years before approaching the endurance limit.

Does the 870 EVO support hardware encryption for BitLocker?

Yes. It supports Class 0 AES 256, TCG/Opal v2.0, and Microsoft eDrive (IEEE1667), so BitLocker can offload encryption to the drive controller instead of your CPU.

Should I buy this or an NVMe M.2 SSD instead?

Choose the 870 EVO when you need a 2.5-inch SATA drive: older desktops, laptops without M.2 slots, NAS bays, or video recorders. If your board has a free M.2 slot and you want maximum throughput, an NVMe drive will be several times faster.

How much shock can this drive take?

It is rated to 1,500 G at 0.5 ms half-sine. Check the product listing for current warranty terms.
