Crucial P5 1TB 3D NAND NVMe internal SSD up to 3400 MB/s – CT1000P5SSD8 review


measures 17x17mm, which is quite large compared to Phison’s E12 and especially the E12S, measuring 16x16mm and 12x12mm, respectively. The reasoning for the size becomes apparent when we dig down deeper into the architecture. 


Crucial’s P5 comes in an M.2 2280 single-sided form factor at all capacities. With all components on a single side of the PCB, the P5 is compatible with almost any mobile device that fits an M.2 2280 NVMe SSD. The finish quality on the P5’s black PCB is very good too.


Crucial outfits the 1TB P5 with a 1GB Micron LPDDR4 2,133 MHz DRAM chip to buffer FTL mapping tables and ensure consistent performance. The company also throws in Micron’s latest 96L TLC flash; however, this is only on the 1TB and 2TB models. 

Read & write speed in Crucial P5 1TB 3D NAND NVMe internal SSD up to 3400 MB/s – CT1000P5SSD8

Crucial’s P5 comes in capacities of 250GB up to 2TB, and current street prices range from $0.15-$0.22 per GB. Crucial says the P5 delivers sequential performance of up to 3.4 /3 GBps read/write as well as up to 430,000 / 500,000 random read/write IOPS when hammered to the max.  All capacities can hit the read spec, but write performance degrades as capacity decreases. At the 500GB capacity point, write performance is rated for up to 1.4 GBps. 

Transfer Rates – DiskBench

We use the DiskBench storage benchmarking tool to test file transfer performance with our own custom blocks of data. Our 50GB data set includes 31,227 files of various types, like pictures, PDFs, and videos. Our 100GB includes 22,579 files, with 50GB of them being large movies. We copy the data sets to new folders and then follow-up with a reading test of a newly written 6.5GB zip file and 15GB movie file.

Data encryption

Crucial’s P5 comes with AES 256-bit hardware encryption supporting the TCG Opal 2.0 and IEEE 1667 feature set and is also configurable with Windows BitLocker since it is eDrive-compliant. 


Next up is a game-launching trace set, which simulates how quickly a drive can read shallow-depth small random 4K packages. Note: 4K is one of the more commonly used file-block sizes for game installations, though that file-block-size tendency does depend on the title you’re playing. That said, 4K small random read is the most accurate block-size metric relevant to these three popular FPS titles: Battlefield 5, Overwatch, and Call of Duty: Black Ops 4.

Crucial P5 1TB 3D NAND NVMe internal SSD up to 3400 MB/s – CT1000P5SSD8 customer review

Speedy little drive

I used the Crucial P5 to replace a slower NVME drive in my laptop. I don’t think my system is allowing it to use its full bandwidth, but it’s about twice as fast regardless.

Installation was a bit of a bear. I have only one NVME slot in my laptop, and so I had to use an external USB enclosure to clone my data. Crucial offers a free version of Arconis TrueImage (as a download from their website) that’s designed to work with their drives, but it only appears to detect drives connected directly to a computer’s NVME slot, so if you’re trying to transfer from an old NVME drive using an external connector, you may have to seek out a different solution.

Once I got the drive cloned and installed, everything went smooth. My benchmarks don’t put it quite at what the specified claims are (and I never expected they would) it’s still very fast and significantly faster than the drive it replaced. Windows 10 cold-boots in about six seconds now.

This comes very close to the speed of a top-end competitor, and I highly recommend it. Just be aware of potential issues when trying to clone data using an external enclosure and the provided software.

-Low endurance rating for heavy data writes-Slow compared to any NMVe SSD

It seems strange that the Crucial MX500 is the only SATA drive left on our list of the best SSDs for gaming, but when the price delta between PCIe and SATA is so small, it’s difficult to make an argument for the far slower technology. But, as there is a hard limit on the number of M.2 slots on your motherboard, there is still a place for SATA SSDs as secondary storage.

It will happily function as a boot drive on systems with no M.2 sockets, or at least no bootable M.2 sockets anyway. You will still be missing out on the zippy response of your operating system running on the SSD-specific NVMe protocol, but if that’s not an option anyway, this drive will see you right. 

And the Crucial MX500 is one of the best. With SATA’s maximum theoretical bandwidth limit of 600MB/s, it’s nearly as quick as you’ll get, and Crucial’s drives have long been among the best-value options available too. This is the most affordable 1TB SATA drive you can pick up and make a great second home for your Steam and Epic libraries.
