Samsung SSD860 EVO 4TB SSD Review

Rating: 8.5.

Samsung has been very quiet on the SSD front lately, but all that has changed with the launch of the SSD860 series of drives aimed at the consumer market space – the successor to the popular SSD850 series.

The SSD860 EVO uses Samsung's latest 64-layer 3-bit MLC (that's TLC to you and me), V-NAND along with a new controller, the MJX. Technical details on the new controller are pretty sketchy to say the least at the time of writing this review.

The 860 EVO is available in five capacities; 250GB, 500GB, 1TB, 2TB and the flagship 4TB – the model we have for review today. It ships in three formats, the standard 2.5in, M.2 and mSATA which basically covers all the bases. The 4TB drive is equipped with 4GB of LPDDR4 cache (the 2TB drive has 2GB, the 1TB model 1GB and both the 512GB and 250GB drives have to make do with 512MB.)

Quoted performance across the range for the 860EVO is 550MB/s for Sequential reads and 520MB/s for writes. 4K random read performance is stated as up to 98,000 IOPS with writes at up to 90,000 IOPS.

The most striking aspect of the 4TB SSD860 EVO is the rated endurance. At 2,400TB TBW it's an 8 times improvement over the previous SSD850 EVO. To further add peace of mind Samsung stand behind the drive with a 5 year warranty.
