Just as the Samsung 850 Evo has dominated the top end of the mainstream SATA SSD market, so the Samsung 850 Pro has dominated the professional end. Through the use of MLC 3D NAND (rather than TLC), it offers long lasting and durable performance.
If you do not necessarily need the fastest drive, you need a solid performance up to the last gigabyte, while having a reassuring guarantee and endurance, that's all you need. was love at first sight The formula remains the same with the Samsung 860 Pro, though – as with the 860 Evo – the hardware under the hood is completely new.
The cornerstone is Samsung's new 64-layer NAND 3D flash memory; because of its use of MLC rather than TLC, it comes in 256 GB. These matrices are joined by the same new MJX controller as the 860 Evo and, again, you get support for LPDDR4. The result is a reader that delivers the smallest gross smog performance on the 860 Evo, with read speeds ranging from 550MB / sec to 560MB / sec, while writing speeds are also up 10MB / sec dry at 530MB / sec. However, the random speeds remain the same at 100K IOPS for reads and 90K IOPS for writes.
One of the major improvements is the power consumption, the new controller, DRAM and NAND using a little less energy than before. It is not that this small energy saving has a lot of impact in the vast majority of use cases, of course.
A seemingly more practical improvement is in endurance, all the capabilities of the 860 Pro now having at least double the endurance – this model of 512 GB can take 600 TB.
However, Samsung has also halved its warranty period from ten years to five years. This change leaves us in the situation where the 860 Pro has considerably less appeal. Even the 850 Pro was overkill for most home users, but at least with a ten-year warranty, anything writing endurance and consistent MLC performance could potentially be put to the test with long-term professional use .
upgrade before the warranty is in place, but this nevertheless reduces the appeal of this drive. Moreover, when it comes to performance, this disc does not do much to justify its premium. This is not slow – it has shone through all our tests and, most importantly, it has no problems with SLC caching and TLC write performance downsizing. However, the effect in terms of performance in the real world is minimal. The Samsung 860 Evo and Crucial MX500 offer performance almost identical to what you will actually notice.
As such, the 860 Pro is a technical success and certainly retains its crown as the fastest SATA SSD.
With its so high price, it encroaches on NVMe drives – for any capacity less than 4 TB, you can just as easily opt for one of these drives. There is still a big jump if you opt for a Samsung 960 Pro, but while the drive itself is also exaggerated for most users. That said, at least the 960 Pro can really claim to be seven times faster than the Pro 860.
Samsung has once again proved that it is at the top of the SSD hill, with its 860 Pro taking the SATA performance crown. However, the case of a high-end SATA drive was already low, and with a decrease in the duration of the warranty, this player makes even less sense to most users. It's a great product, but most people can get a reader who is more than fast enough for their needs for a lot less money elsewhere.
