Plextor M6e 256GB PCI Express SSD Review

Let us continue with the benchmark results. M.2 PCIe modules are currently tested with 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 result …

The SSD benchmark values offers a very good reference point of the maximal possible reading and writing performance, the speed with smaller files and the respective access time.

In AHCI mode the Plextor M6e 256 GB reached fantastic 709.68 MB/s read and 537.28 MB/s write performance. In contrast, the current Crucial MX100 512GB 2,5″ SSD on SATA3 port reached approximately 511.93 MB / s read and 449.24 MB/s write speed, which was measured on a different platform.

Here is a Snipping screenshot of the AS SSD benchmark results (PCIe AHCI):

The comparison of the AS SSD benchmark results is extended with each new HDD/SSD test. Here you can see already some SSDs in comparison to the Plextor M6e 256GB M.2 SSD, whereby the SSD benchmark chart is updated continuously with new SSDs. The top of the AS SSD total score is currently quite clearly led by this Plextor M6e 256 GB M.2 SSD, where even the tests with two SSDs in RAID0 array are significantly below this score.

Here is a comparison of the AS SSD benchmark values, which are getting updated with new drives:

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.

The Plextor M6e 256GB SSD already reached good read speed values (green) from about 16 KB transfer size and the highest transfer values of up to 772476 KB/s from approx. 4096KB transfer size. The write speed (red) achieved high values with a transfer size of approx. 32 KB and the highest transfer values up to 586284 KB/s with a transfer size of about 128KB.

These are also fantastic high scores !

Here is a Snipping screenshot of the ATTO Disk benchmark values (PCIe 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 Plextor M6e is at the ATTO maximum transfer rates directly behind the two RAID0 SSD tests.

Here is a comparison of the ATTO disk benchmark values, which are getting updated with soon coming drives:

CrystalDiskMark result

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

As seen in the previous 4K-64Threads results, the 4K QD32 read and write values are extremly fast, whereby the sequential read measurement reached 744.1 MB/s sequential write measurement reached 575.9 MB/s.

Here is a Snipping screenshot of the CrystalDiskMark values (PCIe AHCI):

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 Solid State Drives and Hard Disk Drives.

The Plextor M6e 256 GB SSD is with its amazingly high read performance even before the Crucial M550 512GB SSD, and is beaten in our tests only by SSD RAID arrays.

Here is a comparison of the CrystalDiskMark values, which are getting updated with soon coming 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 measured with the Plextor M6e 256GB SSD during read and write operations a constant transfer rate with an extremely low random access and extreme high transfer rates. To compare these results you can move the mouse over the following drives to see their respective benchmark results:Plextor M6e 256GB M.2 SSD at PCIe AHCI, ADATA S511 120GB SSD at SATA3 AHCI, ADATA S511 120GB SSD at SATA3 AHCI, Crucial MX100 512GB 2.5″ SSD at SATA3 AHCI, Crucial M550 512GB 2.5″ SSD at SATA3 AHCI, Crucial M500 480GB 2.5″ SSD at SATA3 AHCI, 2x Crucial m4 128GB 2.5″ SSD at SATA3 RAID, Crucial m4 128GB 2.5″ SSD at SATA3 AHCI, Crucial m4 128GB 2.5″ SSD at SATA3, Crucial m4 256GB 2.5″ SSD FW 000F at SATA3 AHCI, Crucial m4 256GB 2.5″ SSD FW 0309 at SATA3 AHCI, Crucial m4 256GB 2.5″ SSD FW 0002 at SATA3 AHCI, Crucial m4 256GB SSD FW 0309 at SATA3 IDE, Crucial m4 256GB 2.5″ SSD FW 0002 at SATA3, Crucial C300 64GB 1.8″ SSD at SATA3, Crucial RealSSD C300 256GB 2.5″ SSD at SATA3, Crucial RealSSD C300 256GB 2.5″ SSD at SATA2, Hitachi 7K1000.C 1TB HDD, MX-DS Fusion 60GB SSD SATA3 IDE, MX-DS Fusion 60GB SSD SATA3 IDE, MX-DS Turbo 120GB SSD at SATA3 AHCI, OCZ Agility 128GB SSD, Samsung Series470 128GB SSD AHCI, Samsung Series470 128GB SSD Legacy IDE, Seagate Constellation.2 1TB 2.5″ HDD at SATA3, Toshiba MK8007GAH 1.8″ hard disk drive.

Here is a Snipping screenhot of the HD Tach benchmark values:

The comparison of HD tach benchmark results shows the great performance of the Plextor M6e 256GB PCIe SSD, which is located clearly at the top of our previously tested SSDs.

Here is an impressive comparison of the HD Tach benchmark values, which are getting updated with soon coming drives:

SiSoftware Sandra benchmark result

Of course, SiSoftware Sandra benchmark should not be missing in this test series. SiSoftware offers with their SiSoft Sandra program a very comprehensive tool, which contains a lot of tools to get very reliable test results of all hardware components.

The average access time of Plextor M6e 128 GB SSD achived in SiSoftware Sandra extremely low 16us and the drive index of 749.71 MB/s is behind the RAID0 at the top.

Here is a Snipping screenshot of the SiSoftware Sandra benchmark read values (PCIe AHCI):

In the write performance measurement, the average access time of the Plextor M6e 256GB SSD in SiSoftware Sandra was 738us and the drive index reached extremly high 548.19 MB/s.

Microsoft Windows 7 Start and Windows performance index

Fortunately, the Plextor M6e 256GB M.2 SSD is bootable. A Microsoft Windows 7 Ultimate boot process took with the Plextor M6e 256 GB M.2 SSD only 4-5 seconds and the entire boot time with BIOS post and Windows 7 start was just 16 seconds ! The Windows 7 “primary disk” performance index of course reached 7.9 of 7.9 possible points.
