Plextor M9P Plus NVMe SSD Review (512GB)

TSSDR TEST BENCH AND PROTOCOL

SSD testing at TSSDR differs slightly, depending on whether we are looking at consumer or enterprise storage media. For our Plextor M9P Plus HHHL AIC NVMe SSD testing today, our goal is to test in a system that has been optimized with our SSD Optimization Guide. To see the best performance possible, the CPU C states have been disabled, C1E support has been disabled, and Enhanced Intel SpeedStep Technology (EIST) has been disabled.

SYSTEM COMPONENTS

The components of this Test Bench are detailed below.  All hardware is linked for purchase and product sales may be reached by a simple click on the individual item. As well, the title is linked back to the individual build article where performance testing can be validated.

BENCHMARK SOFTWARE

The software in use for today’s analysis is typical of many of our reviews and consists of Crystal Disk Info, ATTO Disk Benchmark, Crystal Disk Mark, AS SSD, Anvil’s Storage Utilities, AJA, and TxBench. Our selection of software allows each to build on the last and to provide validation to results already obtained.

CRYSTAL DISK INFO VER. 8.3.1

Crystal Disk Info is a great tool for displaying the characteristics and health of storage devices. It displays everything from temperatures, the number of hours the device has been powered, and even to the extent of informing you of the firmware of the device.

Crystal Disk Info validates that our SSD is running in PCIe 3.0 x4 (four lane), and also that NVMe 1.3 protocol is in use.

ATTO DISK BENCHMARK VER. 3.05

ATTO Disk Benchmark is perhaps one of the oldest benchmarks going and is definitely the main staple for manufacturer performance specifications. ATTO uses RAW or compressible data and, for our benchmarks, we use a set length of 256mb and test both the read and write performance of various transfer sizes ranging from 0.5 to 8192kb. Manufacturers prefer this method of testing as it deals with raw (compressible) data rather than random (includes incompressible data) which, although more realistic, results in lower performance results.

Listed specifications for the Plextor M9P Plus are 3400MB/s read and 2200MB/s write.  As we can see in this ATTO result, the read performance is just below listed specs but nothing to concerns ourselves about.

  1. By the looks of your reviews, it seems that the PCIE 4.0 SSDs are really no better than what we see here, considering the extra heat which must be dealt with, even if sequential R/W is faster. I did notice the excellent 4K Randoms of the PCIE 4.0 SSDs though, very nice.
    It seems to me that for even demanding PC users that in real world use they wouldn’t notice much, if any, differences between them.
    I was all gung-ho over PCIE 4.0 SSDs, however even though the PCIE 4.0 platform is great, the SSDs just seem to not be as important at this time yet.
    Thanks for yet another excellent review, Les.
