The 850 PRO 256 GB is Samsung's flagship consumer-grade SATA SSD. The series features Samsungs latest 3D V-NAND with 24 layers and 128Gbit density. Thanks to this NAND flash memory the drive features a high endurance rating and apart from that also performance should be on a seriously high level.

Not long ago Samsung announced three new SSD series. There is the 850 PRO for endusers
and the 845DC EVO as well as the 845DC PRO for data centers. In the case of the 850 PRO
the most significant upgrade comes with the NAND Flash. Samsung is now
bringing 3D V-NAND to the mass market and therefore increasing reliability and
endurance. To be a bit more precise the drive boasts 24 layer 3D V-NAND with
40nm structures. Apart from that density is a 128Gbit and over time Samsung
wants to increase this value to a whopping 1 TBit.
A closer look at the 850 PRO
reveals that the 256 Gigabyte version is capable of delivering high performance
already with low capacity. It appears that the new 3D V-NAND can deliver high
performance as well as high endurance in combination with Samsungs latest MEX
controller. When it comes to endurance Samsung is saying that the 850 PRO should
be able to survive 150 TBW. Compared to the datacenter drives, where Samsung
communicates 10 drive writes per day, the value of 150 TBW is rather low. We
believe the maker is advertising a low value and in real life the drive is
capable of withstanding way higher TBW numbers.
If we start looking for the
controller, we see there is the Samsung MEX model. This controller clocks 100
MHz higher than the predecessor, which ran by the name MDX. The fact that this
version of the controller clocks 100 MHz faster might also be the reason why the
850 PRO is a bit quicker than the datacenter versions, which use the MDX
controller but also feature 3D V-NAND.
Last but not least let us have a quick look at the exterior. The
Samsung 850 PRO is only available with a 2.5 inch casing measuring 7
millimeter in height. In case of the interface you get SATA 3.1. We're rather
curious to see wether Samsung is planning on releasing an M.2 version of this
drive or not.

Conclusion
Announcement:
Despite the circumstance that the rating of a product is based on as many
objective facts as possible there are factors which can have an influence on a
rating after publication. Every autor may perceive data differently over time
whereas one possible reason for example is a deeper background knowledge or
understanding of certain processes. Certain unforseen market conditions as well
as changes have the potential to render a descision made at a certain point in
time obsolete.
With the 850 PRO Samsung has launched the successor of the 840 PRO, which was
amongst the very fastest drives, when it was launched about one year ago.
Compared to the 840 PRO the 850 PRO basically features the same controller, that
clocks 100 MHz quicker. What's way more important than the updated controller is
the fact, that this drives uses 3D V-NAND, which offers higher reliability as
well as higher performance than standard MLC NAND flash memory.
In terms of raw performance our test drive was able to score 531 MB/s sequential
write and 548 MB/s sequential read throughput. When it comes to 4K
IOPS we measured as near as makes no difference 100'000 IOPS regarding random read and
91'000 regarding random
write. In the case of sequential read as well as sequential write we see that
the SATA-III interface is being maxed out
and therefore performance is where it should be. Apart from these values we also
noticed consistent performance regarding our different queue depth tests.
Last but not least there is the pricing. The Samsung 850 PRO 128GB costs 98
Euro, the 850 PRO 256 GB accounts for 150 Euro, the 512 Gigabyte model is 304
Euro and the 1 Terabyte model sells for 530 Euro. Price per gigabyte is therefore somewhere
inbetween 0.77 and 0.52 Euro, which is basically at the top end compared to the
competition.
Should you be looking for one of the fastest consumer SSDs money can buy, then
the 850 PRO should definitely be considered.
