Crucial P5 NVMe SSD Review (1TB) – PCIe 3.0′ Late Entry to the Ball


Crystal Disk Benchmark is used to measure read and write performance through sampling of random data which is, for the most part, incompressible. Performance is virtually identical, regardless of data sample so we have included only that using random data samples.



Crystal DiskMark results are excellent, displaying write data transfer speeds well above listed spec.  As well, read and write IOPS are very strong.


The toughest benchmark available for solid state drives is AS SSD as it relies solely on incompressible data samples when testing performance. For the most part, AS SSD tests can be considered the ‘worst case scenario’ in obtaining data transfer speeds and many enthusiasts like AS SSD for their needs. Transfer speeds are displayed on the left with IOPS results on the right.The AS SSD results aren’t as appealing as we might like to see but do get a first look at read and write IOPS which appear to be in the general ball park of listed specs.


Anvil’s Storage Utilities (ASU) are the most complete test bed available for the solid state drive today. The benchmark displays test results for, not only throughput but also, IOPS and Disk Access Times. 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.


The AJA Video Systems Disk Test is relatively new to our testing and tests the transfer speed of video files with different resolutions and Codec.


  1. I installed my new Crucial P5 500GB NVMe M.2 SSD just a few days ago, and I’m delighted with it. I had a bit of a problem with recognition by the free Crucial specific version of the Acronis software, but the Crucial support guy was brilliant, talked me through everything while he identified the cause, then emailed me a software patch to get it working, from which point the rest was a doddle. The Crucial Storage Executive management software which is included to download for free from their website is also a significant pluspoint, and has the potential to enable the drive to exceed its stated speed by quite a margin. It wasn’t the cheapest option, though it wasn’t the dearest either, and I feel like I got good value for my money as it’s an excellent drive.

  2. Currently running MSI X99S SLI Plus, i7-5820k, Corsair LPX 4x4GB C14, Samsung 850EVO SATA3 120GB x2 in RAID 1, 2 x WD Scorpio Black 320GB HDD in RAID 1, Radeon RX580, NZXT 850W PSU, Arctic Freezer 11, NZXT case & some very quiet fans. Nice quick system built in 2015, I re-used 2 old WD drives but as they are now very old and (along with EVOs) full, I need more storage, and it needs to be faster too, or I’d consider changing to RAID 0 as I now have external NAS backup. I decided it was time to bite the bullet and buy a fast M.2 NVME PCIE Gen.3 x4 SSD.

    So… I have a strict budget of £120 to get the best 1TB stick that I can – Samsung’s EVO Plus and EVO are great, but above my price range, so I narrowed it down to 3 good value fast performers. The Adata SX8200 Pro, Sabrent Rocket and Crucial P5. All are very well reviewed and on various benchmark sites all have been well received, but there’s not a lot of information out about reliability and compatibility with 5 year old motherboards, even though I did get a good one at the time:

    Adata: Couldn’t find much info on quality of Customer Service support. Hardware-wise, robust smart package. Couple of years old now so firmware established. Supposed to have compatibility with my m/b.

    Sabrent: Again I couldn’t find much info on how good Customer Support was. Hardware-wise, another robust smart package, a bit newer than Adata and I was surprised to find it used Micron 96L cells. Nice. Supposed to have compatibility with my m/b.

    Crucial: Customer Support (from experience with them) is great, also Dami confirms this in the review on here, and their online compatibility tool guarantees it will work with my MSI X99S SLI Plus Big plus point. As is Acronis Truimage for free. Only downside I can see is because the controller uses bigger data blocks in the controller which may hinder access slightly, but their controller writes super quickly. I’m not a major gamer so fractions in loading speed are not madly important for me, but I do need it to shift the data in and out quickly once things are going.

    The result… I chose the Crucial P5 1TB. Crucial themselves in the UK have got it on offer at about £110 on their own website at the moment which is cheaper than I could find the others.

    Should come by Christmas so guess what I’m doing between Christmas and New Year!!!

    Can’t wait…
