What is the Samsung 860 Evo?

The Samsung 850 Evo has been a favourite SATA SSD for some time, smartly combining splendid functioning with a smashing price. Now, Samsung is dorsum with an updated version, the 860 Evo, which improves on the original and bumps up maximum storage to a whopping 4TB.

Design and features

Externally, there really isn't much to say well-nigh the 860 Evo. The two.5-inch version I accept on review here looks pretty much like any other SATA SSD, decked out in a black instance. And while the 1000.2 and mSATA versions of the drive give the 860 Evo range flexibility, they too could laissez passer for any other drive from a range of manufacturers.

Information technology'south on the inside that the real changes have taken place. The main thing that the range brings is a larger capacity, with the 860 Evo available in 250GB (£91), 500GB (£162), 1TB (£316), 2TB (£620) and 4TB (£1324) options. At such sizes, the demand for mechanical disks is rapidly shrinking, and these older drives remain popular for their extremely depression prices only.

Impressively, although the high-chapters drives are expensive, the price per gigabyte remains steady through the range, costing between 31p (2TB version) and 36.4p (250GB version) per gigabyte. Ultimately, this shows that yous're not paying over the odds for larger capacity drives.

Nevertheless, the high-capacity 860 Evo drives are still an expensive buy, although the 500GB or 1TB versions hit the sugariness spot betwixt price and capacity.

Samsung has switched to using V-NAND 3-chip MLC technology for storage, which is designed to be more reliable. As a result, the SSD warranty has been extended from iii years with the former model to a salubrious five years with the 860 Evo. Samsung promises endurance of up to 2400TB of full bytes written, which is 8 times higher than the 850 Evo. Certainly, when comparing prices between the one-time and the new, longevity should form function of your ultimate decision.

Performance

With the SATA 6Gbits/sec interface limited to 600MB/sec, in that location's simply and then much that can exist done with a new drive. As a result, Samsung has maxed out performance across the board, promising sequential read speeds of 550MB/sec and write speeds of 520MB/sec. This is partly thanks to the new Samsung MJX Controller.

So, how does the bulldoze perform in real tests? Testing with CrystalDiskMark, I've found that Samsung'south claims are spot on. Running the sequential test, I achieved a read speed of 508.8MB/sec and a write speed of 526.8MB/sec. So far, that'southward very good; only other SATA SSDs take come close to this score. Switching to the tougher 4K random read/write test displayed the true power of the 860 Evo and I saw read speeds of 338.7MB/sec and write speeds of 324.2MB/sec.

As a comparing, I likewise tested the old 850 Evo using a 2TB version of the drive. In CrystalDiskMark, the sequential read speed of 492.4MB/sec and write speed of 523.2MB/sec aren't far off the stride set by the 860 Evo. However, switching to the 4K random examination showed the difference, and the Evo 850 managed a read speed of 318.6MB/sec and a write speed of 324.1MB/sec.

Running ATTO Disk Benchmark saw the 860 Evo perform well, too. Running with 4KB file sizes, the drive managed read speeds of 332.95MB/sec and write speeds of 314.5MB/sec. At file sizes above 64KB, ATTO reported the drive equally capable of a nippy read speed of 563.94MB/sec and a write speed of 535.68MB/sec. There'south no incertitude, then, that the 860 Evo is the fastest SATA-based SSD I've tested – but simply only, thank you to the limits of the SATA interface.

Why buy the Samsung 860 Evo?

With the 860 Evo, Samsung has managed to squeeze every last driblet of performance out of the ageing SATA 6Gbits/sec interface. If you have a computer with a more modern NVMe interface, you lot'll reach improve performance by ownership a drive to match, such as the excellent Samsung 960 Evo, which easily outperforms the 860 Evo.

That said, if you're looking for value, or you have an older computer that tin't take an NVMe drive, so the 860 Evo is the drive to buy. Information technology'southward a little more expensive than the older 850 Evo, with the 1TB version costing £46 more at launch. But, in my stance, this is money well spent. Not just practise you get the improved performance of the new drive, just yous benefit from increased reliability too.

Verdict

Samsung has pushed the ageing SATA 6GB/southward interface to its limits with this fast, well-priced and ultra-reliable SSD.
