Samsung XP941 M.2 PCIe SSD Review (512GB) – New Ultra Standard Exceeds 140K PCMark Vantage Score

ANVIL STORAGE UTILITIES PROFESSIONAL (BETA)

You may not see this for long (and it’s definitely not common) but you get a freebee simply for reading! Over the last little while, we have been assisting with beta testing new benchmark software called Anvil Storage Utilities which is an absolutely amazing SSD benchmarking utility. Not only does it have a preset SSD benchmark, but also, it has included such things as endurance testing and threaded I/O read, write and mixed tests, all of which are very simple to understand and use in our benchmark testing.

As much ASU provided some great throughput and IOPS results, this is the first time we could get an example of what the Samsung XP941 M.2 PCIe SSD could do with respect to disk access times (Resp. Time) and its speed here is very impressive, no doubt making a large contribution to the final Total Point Score.

PCMARK VANTAGE X64 HDD SUITE

The SSD Review uses benchmark software called PCMark Vantage x64 HDD Suite to create testing scenarios that might be used in the typical user experience. There are eight tests in all and the tests performed record the speed of data movement in MB/s to which they are then given a numerical score after all of the tests are complete. The simulations are as follows:

  • Windows Defender In Use
  • Streaming Data from storage in games such as Alan Wake which allows for massive worlds and riveting non-stop action
  • Importing digital photos into Windows Photo Gallery
  • Starting the Vista Operating System
  • Home Video editing with Movie Maker which can be very time consuming
  • Media Center which can handle video recording, time shifting and streaming from Windows media center to an extender such as XBox
  • Cataloging a music library
  • Starting applications

SAMSUNG XP941 M.2 PCIE SSD VANTAGE RESULTS

Samsung’s XP941 provided one of the best results we have ever seen in PCMark Vantage Testing with a Total Point Score of 119053.  Not only did every result easily surpass the former bottleneck known as SATA 3, but also, the top transfer speed reached was that of 847MB/s while working in Media Center.

Vantage TotalEven more impressive was the result we saw in Vantage when the system was optimized, bumping the Total Score to 140455 and a top transfer speed of 947MB/s:

OPT Samsung XP941 M2 512GB Vantage 140KWhen comparing to any SATA 3 SSD, there really is no comparison for us to demonstrate just how much faster the Samsung M.2 PCIe SSD is compared to the competition.  Just as an example, we have provided Vantage results of the fastest similar form factor SSDs tested to date.  Don’t let the fact that we have left out notebook SSDs from this chart influence you; the XP941 blows all of them away as well.

“The XP941 is fast becoming the ‘new standard’ and Samsung’s inability to
provide review samples to media demonstrates the demand that they are
challenged with.”
In my opinion Apple just prohibited a distribution of this devices for maybe half a year. It’s like the new Haswell chips from Intel. They pay a premium price and get the chips exclusively.

Which pcie slot was the ngff adapter on? There’s additional latency if it’s connected to the x4 lane from the pch.

Les@TheSSDReview

X16 first slot on the Asus Maximus VI.

Were any drivers needed for windows to be installed on this? A nvme driver might
improve performance

Les@TheSSDReview

No drivers were needed whatsoever. It was recognized and formatted without issue in the adapter. If you would like to suggest a possible driver, by all means we can try it out if it might improove the end IOPS.

I recently purchased a Samsung Ativ book 9 plus. It has an msata toshiba ssd in it with a 2280 form factor. It is supposedly an m.2 form factor, but does that mean the controller actually resides on the drive ? Thanks.

The controller IC is almost always soldered right to the PCB of the SSD regardless of form factor.

Thanks ! Forgive my ignorance, but that mean the system would also support a pci-e m.2 drive in the 2280 form factor ?

Yes I am wondering about your system as we arent aware of Samsung having released systems with the new PCIe as of yet. Can you do an ATTO or crystal DiskMark test and let us know the scores?

Here is the Crystal. Haven’t figured out how to post the atto. Nothing special about the drive, but I thought the M.2 spec supported a dual pci-e/sata configuration.

That is not what I was looking for although you answered a question. The SSD in there is a mSATA and only 128GB so you wil only get nominal performance.. Send an ATTO or Crystal Diskmark result with the performance results….not Crystal Disk Info

Here is the Crystalmark. This is on battery and performance power profile. Might eke out a bit more plugged in. I am still not sure if this machine will support a pci-e ssd since it’s M.2 ? ———————————————————————– CrystalDiskMark 3.0.2 Shizuku Edition x64 (C) 2007-2013 hiyohiyo Crystal Dew World : http://crystalmark.info/ ———————————————————————– * MB/s = 1,000,000 byte/s [SATA/300 = 300,000,000 byte/s] Sequential Read : 499.798 MB/s Sequential Write : 467.002 MB/s Random Read 512KB : 387.263 MB/s Random Write 512KB : 396.608 MB/s Random Read 4KB (QD=1) : 18.569 MB/s [ 4533.6 IOPS] Random Write 4KB (QD=1) : 49.599 MB/s… Read more »

In looking at this performance, you either have a mSATA or M.2 SATA SSD installed. In any event, you could not install a PCIe that would get better performance than this as your system is limited to the SATA speeds. What is your system model number.

Thanks ! It’s NP940X3G-K01US. It’s a 2280 M.2 form factor according to some folks on a forum. It’s a “gumstick” ssd.

Les@TheSSDReview

Yup it may be, however, it is most likely still a SATA M.2. There is a difference between PCIe M.2 and SATA M.2 SSDs which, believe it or not as as small of a difference as the switching of wires in the interface. The end result, however, is that the SATA M.2 is still limited to SATA speeds as you are seeing here. Your SSD is the Toshiba version and, in fact, we are about to review the 512GB capacity of that same SSD very shortly…have it right here in front of me.

Thanks much, Les. At least now I can stop drooling over the pcie ssds ! I’ll still be upgrading this once I can find something bigger and with the appropriate form factor. Looking forward to your review of the 512 GB version.

I own a Vaio Pro 13 and it’s an European version, so a SATA M.2 is installed. I’ve got a 128 GB SSD because an upgrade to 265 GB would have cost me $ 220 (€160). I figured I could spend $220 for another SSD and own 2 SSD instead of 1. But at the moment of buying the laptop I wasn’t aware a M.2 SSD would be installed, guess I should have know better with such a small laptop 😉 So now I’ve got some questions while I’m searching for a new SSD, but there’s not so much information… Read more »

That article says ‘possibly both’ but that is not possible at this point. It is either one or the other, and quite frankly, I don’t see how it is possible. The system you have is a SATA M.2 and youre next quest will be to find a larger M.2 SSD no doubt.

P.S. We tried the XP941 on the SATA system and it didn’t work.

Thx for the clear and fast answer, then I’ll go looking for a bigger SATA M.2. Now I only have to wait until they are available 🙂 And I wasn’t talking about the Asus Maximus mentioned in this article, but the motherboard used in the Vaio Pro. I tried to figure out which motherboard is used by the Vaio and Everest only gives the following information: Sony SVP1321C5E. CPU-Z only mentions Sony as the manufacturer of the motherboard with VAIO as the model.

Enuff already!!! They need to start selling the m.2s at newegg along with a simple 4x PCIE adapter. Nearly every mobo has an empty 4x slot in between the 1x and 8x/16x slots. Even better, since the m.2s are so small, LSI could make a killing by making a raid0 capable x4 adapter with room for a pair of m.2s. But noooOOO….everyone one’s gonna wait till next year for sata express to launch. Gah!!
