Samsung 860 EVO 4TB SATA SSD

The Samsung 860 EVO MZ-76E4T0E is a 2.5-inch internal solid state drive with a 4TB capacity. It uses a SATA III interface and Samsung V-NAND 3-bit MLC memory with a Samsung MJX controller and 4GB LPDDR4 cache. It is built for everyday computing in mainstream PCs and laptops.

Installation and common issues

The drive fits any standard 2.5-inch SATA bay and connects with a regular SATA data and power cable. No special drivers are required for modern operating systems. A frequent mistake is connecting the drive to a SATA II port, which limits the sequential speeds well below the rated 550 MBps read and 520 MBps write.

Deciding specification — 4TB capacity

The single figure that determines fit is the 4TB capacity. It provides space for large media libraries, games and backups on a SATA platform. The drive is rated for up to 2400 TBW over five years with an MTBF of 1500000 hours. Active power draw peaks at 4.0W and averages 3.0W, while idle power is a maximum of .5W.

Questions about this item

How can I confirm the 860 EVO is delivering the rated 550 MBps sequential read after installation?

Run a benchmark such as CrystalDiskMark using a 1 GiB test file on a SATA III port; the sequential read result should approach 550 MBps and the 4 KB QD32 random read should reach about 98,000 IOPS.

What does the white-box package contain and what must I supply myself?

The box holds only the 2.5" 4 TB drive; you must provide a SATA data cable, a SATA power connection and a 2.5" drive bay or adapter for your chassis.

Which capacity in the 860 EVO range matches the 2,400 TBW endurance figure?

The 4 TB model carries the 2,400 TBW rating for the five-year warranty period; smaller capacities have lower TBW values.
