With modern solid-state drives practically filling the bandwidth limit of SATA III, it seemed impossible to improve any further in this field. Samsung continues to break new ground with its incredibly stable and dependable 860 Pro SSD.

In spite of the fact that it only performs a little bit better in terms of read and write speeds, the Korean electronics firm has completely revamped the world’s best SATA SSD.

Samsung 860 Pro: Features

With Samsung’s latest 64-layer V-NAND technology, the 860 Pro series boosts its sequential read and write speeds from 560 MB/s to 530 MB/s. The Samsung 850 Pro’s new read and write speeds are only an additional 10 MB/s, but we’re starting to hit the theoretical limit of SATA III, which is 600 MB/s.

In addition to the larger memory capacity, Samsung also introduced a 4TB capacity version of the 860 Pro, though it comes with a ridiculously high price tag of $1,899 (about £1,360, AU$2,380).

Thanks to the smaller and more affordable SSDs now available, prices start from $139 for 256GB, $249 for 512GB, $479 for 1TB, and $949 for 2TB.

Samsung has built a new MJX control on top of its 2bit MLC V-NAND architecture to improve speed and reliability. Featuring AES 256-bit hardware-based encryption and Self-Encrypting Drive technology, you can expect your data to remain secure.

In addition, Samsung guarantees the 860 Pro will survive writing 4,800 terabytes without a single failure – eight times the “Total Bytes Written” (TBW) guarantee of the Samsung 850 Pro.

BENCHMARKS

  • Crystaldisk Mark (Sequential) Read: 562.9 MB/s; Write: 532.7 MB/s
  • Crystaldisk Mark (Random) Read: 353.5 MB/s; Write: 345.2 MB/s
  • ATTO Benchmark (Sequential) Read: 564.5 MB/s; Write: 535.5 MB/s

Performance

SSDs such as the 860 Pro is not exponentially faster than SSDs such as the 850 Pro. In our testing, we only noticed a negligible speed increase of 1 to 2 MB/s.

This isn’t a problem with Samsung’s 64-layer V-NAND, but with the 6 Gbps limitation of the SATA III standard. Solid-state drives based on SATA simply cannot use any more bandwidth, and it’s at the expense of all of them.

Despite that, the Samsung 860 Pro offers some of the fastest data transfer speeds we’ve seen from SATA SSDs. At the same time, the new MJX controller and all the other improvements make it stand out from the competition.

Pros Cons
Improved security and reliability SATA III limits maximum write and reads speeds
New 4TB capacity model
Slightly faster speeds

Conclusions

You won’t lose much if you recently bought a Samsung 850 Pro or 850 EVO SSD. Enterprise users will benefit most from the Samsung 860 Pro’s improved security, reliability, and 4TB capability.

In light of SATA III’s limitations, it is hard to justify the purchase or upgrade of this drive over Samsung’s last generation SSDs – which will more than likely become more affordable in the months to come.
