Head to head
Samsung 860 EVO 1TB vs Samsung 860 EVO M.2 250GB
Our pick
Samsung 860 EVO 1TB
For files that must be encrypted on the drive itself
Why this one
- Check that your system supports the drive’s security mode and that you can configure and activate it. A hardware-encryption capability does not establish that stored files are already protected.1
- Choose the Samsung 860 EVO M.2 1TB for its documented hardware-encryption capability when the supported security setup meets your needs. It fits a SATA-compatible M.2 2280 slot.1

What Samsung 860 EVO M.2 250GB offers
Choose the 860 EVO M.2 250GB for a modest file collection in a computer that accepts a SATA M.2 2280 drive. Check SATA support in the socket before buying.1 Its warranty ends after five years or 150 TB written, whichever comes first; compare both limits with your expected writes.1
