Who like to purchase a current Intel Z97, X99, etc. motherboard or get at least information about an update, certainly have discovered that some motherboards are coming with a so-called M.2 socket. But what exactly is M.2, which devices can you install and how fast is the transfer rate of this M.2 socket ? These and many other questions will we be explained in this very special review of the Plextor M6e 256GB PX-G256M6e PCIe M.2 2280 SSD and of course also the performance of the new M.2 SSD will be tested in practice. We are excited !
Thanks for the support …
Many thanks for the support with the Plextor M6e 256GB M.2 SSD by the manufacturer Plextor.
The Plextor PX-128M6e 256GB M6e M.2 PCIe SSD has at present a price of approx. 180 Euro (09/2014).
The Plextor M6e SSD series contains the following models: – Plextor M6e 128GB PX-G128M6e – Plextor M6e 256GB PX-G256M6e – Plextor M6e 512GB PX-G512M6e
This is also available for a 15-20 EUR charge together with a PCI Express card, recognizable by the “AG”: – Plextor M6e 128 GB PX-AG128M6e – Plextor M6e 256 GB PX-AG256M6e – Plextor M6e 512 GB PX-AG512M6e
The write performance of this Plextor M6e SSD series alters depending on the capacity. The larger the SSD capacity, the faster is the Plextor M6e SSD write performance. The read performance is specified for all three M.2 SSDs with up to 770 MB/s and according to Plextor, the write performance of the M6e 128 GB SSD is up to 335 MB/s, M6e 256 GB SSD up to 580 MB/s and M6e 512 GB SSD up to 625 MB/s.
The supply of the Plextor M6e 256GB PCIe SSD …
In this package came the tiny Plextor M6e M.2 SSD PCB. The plastic packaging can be opened easily by pressing the back part backwards. This is an exemplary blister packaging, which can be closed again even without any problems:
That is contained in the delivery …
The Plextor PX-G256M6e M.2 SSD was delivered without additional accessories.
On the front of the contained Plextor M6e 256 GB SSD you can see the Plextor M6e label with a few technical data such as the voltage of 3.3V and the preinstalled firmware version 1.03, which we will update before the tests:
By the way, under the label is located the 512 MB DDR3 cache module. On the back you can see the Marwell 88SS9183-BNP2 Dual Core Controller IC and four of the eight Toshiba toggle NAND modules of this PCIe SSD with 256 GB total capacity. The M.2 SSD features like the previous SSDs also a built-in 256-bit AES encryption:
What is M.2 PCIe, 2280, Gen2 x2, etc. … ?
Before it comes to the nitty-gritty, we like to provide but some background information, first. Because regarding this SSD type, there are a few names that might be perhaps a little confusing. Let’s start with M.2 … M.2 replaces the previous mSATA standard, which was not only a bottleneck with its maximum SATA 6.0 Gbit/s connection, but also allowed only a SATA connection.
The new M.2 standard – also called NGFF – which stands for next generation form factor – allows both, the use of M.2 SATA3 modules as well as M.2 PCI Express modules and with a connection of four PCI-Express lanes, so x4. For the M.2 Socket there are by the way not only flash modules, but also e.g. M.2 Wi-Fi modules and M.2 Bluetooth modules.
The tested Plextor M6e 256 GB SSD is connected with Gen2 x2 and allows theoretical transfer rates of up to 10 GB/s. For a more easily check if the connection setup is correct, the Plextor BIOS shows the connection rates during the boot process. You should check whether PCI Express Gen02 x02 is listed, to achieve the highest possible performance with this SSD. Unfortunately currently there is no option to turn off or hide this bootscreen, after checking it once.
The ASRock Z97 Extreme6 motherboard used in the test has even a so-called Ultra M.2 Socket, which supports PCIe Gen3 x4 and could allow up to 32 GB/s -so the motherboard should not be a bottleneck.
The size of the small M.2 printed circuit boards varies. The width varies from currently 12, 16, 22 or 30 mm and the length of the M. 2 modules can be 16, 26, 30, 38, 42, 60, 80 or 110 mm. Our Plextor PX-G256M6E has a width of 22 mm and a length of 80 mm. For this reason, this SSD is also called Plextor PCIe M.2 2280 SSD.
So before buying, you should take a look, if this module size is supported by the respective motherboard or notebook, Tablet, etc., or may be buying a PCI Express card is required, it can be ordered for example here *Ad.
In our test, the Plextor M6e 256GB PCIe M.2 2280 SSD is installed directly on the motherboard without a PCI Express card.
Here you can see again the assembled PCI Express Gen2 x2 SSD in the Ultra M.2 socket.
The M.2 PCIe PCB is just inserted angular in the M.2 Socket, then carefully press down and mount it with the screw supplied with the motherboard – btw. in the right of this image a second M.2 slot with different lengths of 30, 42, 60, 80 and 110 mm can be seen.
Here you can see again the screwed M.2 PCIe SSD on the Z97 motherboard.
