What is the Samsung 860 Evo?

The Samsung 850 Evo has been a favorite SATA SSD for a while, well combining glorious efficiency with an ideal worth. Now, Samsung is again with an up to date model, the 860 Evo, which improves on the unique and bumps up most storage to a whopping 4TB.

Samsung 860 Evo – Design and options

Externally, there actually isn’t a lot to say concerning the 860 Evo. The 2.5-inch model I’ve on assessment right here seems to be just about like every other SATA SSD, decked out in a black case. And whereas the M.2 and mSATA variations of the drive give the 860 Evo vary flexibility, they too might cross for every other drive from a variety of producers.

It’s on the within that the true modifications have taken place. The major factor that the vary brings is a bigger capability, with the 860 Evo obtainable in 250GB (£91), 500GB (£162), 1TB (£316), 2TB (£620) and 4TB (£1324) choices. At such sizes, the necessity for mechanical disks is quickly shrinking, and these older drives stay widespread for his or her extraordinarily low costs solely.

Impressively, though the high-capacity drives are costly, the associated fee per gigabyte stays regular by means of the vary, costing between 31p (2TB model) and 36.4p (250GB model) per gigabyte. Ultimately, this exhibits that you simply’re not paying over the percentages for bigger capability drives.

Even so, the high-capacity 860 Evo drives are nonetheless an costly buy, though the 500GB or 1TB variations hit the candy spot between worth and capability.

Samsung has switched to utilizing V-NAND Three-bit MLC expertise for storage, which is designed to be extra dependable. As a outcome, the SSD guarantee has been prolonged from three years with the outdated mannequin to a wholesome 5 years with the 860 Evo. Samsung guarantees endurance of as much as 2400TB of complete bytes written, which is eight instances greater than the 850 Evo. Certainly, when evaluating costs between the outdated and the brand new, longevity ought to type a part of your final determination.

Samsung 860 Evo – Performance

With the SATA 6Gbits/sec interface restricted to 600MB/sec, there’s solely a lot that may be achieved with a brand new drive. As a outcome, Samsung has maxed out efficiency throughout the board, promising sequential learn speeds of 550MB/sec and write speeds of 520MB/sec. This is partly due to the brand new Samsung MJX Controller.

So, how does the drive carry out in actual assessments? Testing with CrystalDiskMark, I’ve discovered that Samsung’s claims are spot on. Running the sequential check, I achieved a learn velocity of 508.8MB/sec and a write velocity of 526.8MB/sec. So far, that’s excellent; however different SATA SSDs have come near this rating. Switching to the more durable 4K random learn/write check displayed the true energy of the 860 Evo and I noticed learn speeds of 338.7MB/sec and write speeds of 324.2MB/sec.

As a comparability, I additionally examined the outdated 850 Evo utilizing a 2TB model of the drive. In CrystalDiskMark, the sequential learn velocity of 492.4MB/sec and write velocity of 523.2MB/sec aren’t far off the tempo set by the 860 Evo. However, switching to the 4K random check confirmed the distinction, and the Evo 850 managed a learn velocity of 318.6MB/sec and a write velocity of 324.1MB/sec.

Running ATTO Disk Benchmark noticed the 860 Evo carry out nicely, too. Running with 4KB file sizes, the drive managed learn speeds of 332.95MB/sec and write speeds of 314.5MB/sec. At file sizes above 64KB, ATTO reported the drive as able to a nippy learn velocity of 563.94MB/sec and a write velocity of 535.68MB/sec. There’s little question, then, that the 860 Evo is the quickest SATA-based SSD I’ve examined – however solely simply, due to the bounds of the SATA interface.

Why purchase the Samsung 860 Evo?

With the 860 Evo, Samsung has managed to squeeze each final drop of efficiency out of the ageing SATA 6Gbits/sec interface. If you will have a pc with a extra fashionable NVMe interface, you’ll obtain higher efficiency by shopping for a drive to match, corresponding to the superb Samsung 960 Evo, which simply outperforms the 860 Evo.

That stated, in the event you’re in search of worth, or you will have an older laptop that may’t settle for an NVMe drive, then the 860 Evo is the drive to purchase. It’s just a little dearer than the older 850 Evo, with the 1TB model costing £46 extra at launch. But, for my part, that is cash nicely spent. Not solely do you get the improved efficiency of the brand new drive, however you profit from elevated reliability too.


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