SAMSUNG 840 PRO SATA 3 SSD
We have always been amused with Samsung because, although they were the second to put out an SSD with their first 64GB MLC SSD (costing $1130), they soon seemed to disappear from the SSD race. In 2010, we got our hands the Samsung 470 Series SSD which had been released some time before yet not reviewed and, if you would believe it, we went on record stating this SSD was the best of the best and an undiscovered gem. Other reviews followed suit confirming our claims and, just like that, Samsung was a force to contend with. This remains valid today with the 840 Series SSD being the world’s most sought after SSD.
These are excellent results from a SATA 3 SSD and if you look at trends with others today, value seems to be taking the place of performance where we are now seeing typical read performance above 500MB/s, yet write speeds are commonly ion the mid to high 300MB/s range.

Even with a power on count of 1020, over a thousand hours of use and over 2TB of throughput, this SSD still performs as if it were new.
AS SSD confirms the performance with a great Total Score over 1000. If you liked PCIe Copy Bench speeds though, hold your breath because SATA speeds aren’t quite as fine…
ANVIL STORAGE UTILITIES PROFESSIONAL (BETA)
A PCMark Total Score of 57756 is typical of what we might see in a SATA 3 SSD because PCMark Vantage provides the best results to new SATA 3 SSDs. Even having recognized this, we are still very happy with the performance, and lifespan, this SSD has had.
Thanks for the article Les!
It’s great to see you opening up your reviews to more hardware while still keeping it relevant
to storage technologies!
I like the mobo but i still say that two 840 pros in raid 0 are still the way to go perf wise.
That said i can clearly see the patern of where the industry is moving and that’s the M.2.
Can you elaborate on that? All the benchmarks suggest that’s not the case, but I could be misinterpreting the data as I’m new to the I/o performance conversation.
I am just happy to see the XP941 being so fast as is. For me it’s win-win as the size of my 1U’s shrink, and at they same time they get faster, and bootable. I will use them to load my data into a RAM template, and rarely write to them. Lets hope our M$ gatekeepers will let us use 24GB out of 32GBs w/o any performance issues.
Hi I am glad I look at this site quite often I think you do
a real good job on everything ssd.
Also I am thinking of buying an extreme 6- Z97 1150 socket with a 4790k canyon this xmas.
Plus the Samsung M.2 XP941 128 I just don’t know?
I was originally going for Asus Maximus Ranger plus the
4790k Canyon and two Samsung 120 gb 850
EVO SSD’s Many thanks if you can help.
It’s easy.
You’ve seen the 840p results. Multiply by 2X and take -10% out.
You’ll find that you are around the same “1GB/S” read/write territory as the M.2’s.
BUT you also get to enjoy that sweet fast ramp up in performance in the low end up to 8K. The 4k write will also be about double.
Just curious, are the M2 slots eligible to be included in a RAID set?
Of course the could be used that way but you have to consider that the RAID set of two XP941 SSDs would be restricted to the lowest speed which is dual lane travel. That might get you a negligible improvement on the XP 941 alone in the ultra M.2 slot. Just to be sure I will try to do this prior to taking off for China in a few days…
Just to cover all the bases, can the M2s be in a mixed RAID with equal sized SSDs?
I wonder…what if there were 2 M.2 x4 slots on that board….combined with 2x XP941….
Then any thought of decent gfx, other than integrated…might be gone. Intel needs to increase total PCIe lane count for something like that.
I wouldn’t care for 1x8PCIE for Graphics ( don’t think it would hurt performance much) and 2x4PCIE lanes for M.2…but you’re right…Intel needs to increase lanes to 24+ for something like this to happen properly…
X79! 40 pci-e lanes if using a 6 core SB-E or Ivybridge-E. Too bad it came out in 2011 and X99 isn’t here yet and no X79 boards with M.2 connectors.
I’m actually pretty satisfied with Intel’s iGPU.
I’d love to see two M.2 slots running at PCIe x4, combined to RAID 0, and which can be booted from. Oh my…
Exactly, like if an X79 board were to sprout some M.2 connectors in a larger than regular ATX size then one would have 40 PCI-e lanes with which to delegate 8 lanes to GPU A, 8 to GPU B, 4 or 8 to your m.2 SSD’s, and use the rest for the other crap that needs to ride the pcie bus. Perhaps in X99?
Such a great article, so glad M.2 is finally arriving…
