Samsung SSD860 PRO 4TB SSD Review

Samsung's mighty SSD850 PRO has been around for quite some time, but at long last it now gets a successor in the shape of the SSD860 PRO. The new drive replaces the 32-layer V-NAND of the 850 with 4th generation 64-layer V-NAND and also brings a new controller to the table in the form of the MJX which replaces the MEX of the 850 series.

Official performance figures for the 4TB SSD860 PRO are quoted as 560MB/s and 530MB/s for Sequential read and writes respectively while random 4K performance is stated as up to 100,000 IOPS for reads with writes at up to 90,000 IOPS. These figures are the same right across the SSD860 range.

We confirmed the Sequential figures with the ATTO benchmark, the review drive yielding 564MB/s for reads and 532MB/s for writes. When it came to the random read/write performance, the review drive didn't quite hit either of the official highs with reads at 97,992 IOPS and writes at 88,246 IOPS. However that write figure is the fastest we have seen for a 1TB+ 2.5in drive to date.

To keep your data secure the SSD860 PRO supports AES 256-bit hardware encryption as well as  TCG/Opal v2.0 and Encrypted Drive (IEEE1667) protocols.

The endurance figures for the new drives is very impressive. The 4TB drive has a rating of 4,800TBW, a figure which is a whopping 8 times better than the previous generation 850 PRO. However the 10 year warranty that backed the 850 PRO has been cut in half to 5 years for the SSD860 PRO.

Pros:

• Performance.
• Endurance rating.
• 5 year warranty.

Cons:

• Pricey

Kitguru says: Samsung's successor to the mighty SSD850 PRO has been a while in coming and the SSD860 carries on where its predessor left off. It uses the latest fourth generation Samsung V-NAND to good effect and has an outstanding endurance rating to boot. But it does carry a hefty old price tag.
