Benchmark values and test results …

Let us continue with the benchmark results. SATA3 drives are tested with an ASRock 890GX Extreme3 motherboard (for comparing with the first SSD results) and test results of M.2 modules are performed using an ASRock Z97 Extreme6 motherboard. At present, Microsoft Windows 7 Ultimate Edition is used as the operating system.

The SSD drive speed was examined and compared with the following benchmark software:
AS SSD Benchmark 1.4.3704.27281 – Download
ATTO Disk Benchmark v2.46 – Download
CrystalDiskMark 3.00 – Download
HD Tach 3.040 – Download
SiSoftware Sandra 2013 – Download

AS SSD benchmark result

The SSD benchmark results offers a very good reference point of the maximal possible reading and writing performance, the speed with smaller files and the respective access time. The 525 GB Crucial drive achieved a relatively high sequential read and write speed in AHCI mode.

In AHCI mode also another result beneath the read performance was much higher than in the IDE mode and that is the important value “4K-64Thrd”. 4K means that small 4K blocks are read and/or written and with the 4K 64Thrd this is distributed on 64 Threads at the same time. Thus the benchmark program simulate for example a typical program start.

Because the weighting of this value in the AS SSD benchmark tool is very high, the total score in AHCI mode is with 1087 points much higher than in IDE mode and is thus directly behind the result of the MX200 500GB M.2 SSD. The bigger 2.5″ Crucial MX300 750GB SSD reached 892 points, Crucial MX200 500 GB SSD reached 882 points, the Crucial BX100 500 GB SSD reached 803 points, the Crucial MX100 512 GB SSD reached 856 points, the Crucial M550 512 GB SSD reached 907 points and the Crucial M500 480 GB SSD reached 685 points – tested in AHCI mode on the same test system.

The usable capacity of the Crucial MX300 M.2 SSD is 489.05 GB. With the Crucial storage Executive tool you can also customize the Over Provisioning area and therefore itself determine how high you would adjust the SSD durability vs performance.

Tip:
Who now think about changing the SATA port in the BIOS from native / legacy IDE to AHCI, should first change for example only one part of the SATA port, where the drive with the operating system is not installed, if this is supported by the motherboard. Because if one like to save the new Windows installation, one must install the hard disk controller driver before changing SATA mode from IDE to AHCI – alternatively there are also Registry entries for it. If you like to upgrade from HDD to SSD, you should not copy the content 1:1 only with a tool like Norton Ghost or Acronis Backup. It is better to install a fresh Windows 7, Windows 8 or Windows 10 or adjust at least the SSD Alignment.

The comparison of the AS SSD benchmark results is extended with each new HDD/SSD test. Here you can see some SSDs in comparison to the Crucial MX300 525 GB M.2 SSD, and the graphic will be updated periodically with new SSD drives. At the moment the top of total AS SSD scores is lead from the Samsung 960 Pro NMVe SSD, followed by some more SSDs and before the MX200 500GB M.2 SSD joins then the latest MX300 M.2 SSD with 525 GB.

ATTO disk benchmark result

The ATTO disk benchmark values gives a very good overview about the write and read rate on different file sizes. These values are maximum ratings, which are different to the previously continuous transfer rate benchmarks, since this benchmark may even reach a higher overall performance with slower SSDs.

At the Crucial MX300 525 GB M.2 SSD is the read speed (green) from a transfer size of about 128 KB higher than the write speed (red) and reaches the maximum read speed of 508739 KB at a transfer size of 64 KB. However, it is striking that the write throughput at 4096 KB drops even after several passes.

Here is a screenshot of the ATTO Disk benchmark values (M.2 SATA3 AHCI):
crucial_mx300_525gb_m2_atto_ahci

The ATTO disk benchmark values are compared with a small transfer size of 32KB and a large transfer size of 8192KB. The bar chart already includes a comparison to some SSDs and HDDs, where the Crucial MX300 M.2 in ATTO can classify only at the bottom.

CrystalDiskMark result

With CrystalDiskMark one receives a balanced measurement of the performance with different transfer sizes.

Here especially the 4K-64Threads values like before has enormously high sequential read values of 496.1 MB/s and write values of 461.0 MB/s.

The following diagram shows the CrystalDiskMark results once again compared with other SSDs and platter drives, which are extended step by step. In the CrystalDiskMark comparison one can see significant differences between the to-date tested of the Solid State Drives and Hard Disk Drives.

HD Tach result

With HD Tach one can measure the gradient of the performance, but the SSD transfer is not comparable with a conventional HDD. New logical NAND cell access of the SSD controller results like some other equal designed SSDs in strong varying values with the latest HD Tach Version 3.0.4.0 version, which is written for hard disk drives.

HD Tach shows the Crucial MX300 525 GB M.2 SSD in AHCI mode at a continuous read rate with the lowest displayed access time display of approx. 0.0ms. There are however strong peaks during the write operations.
