Previewed at last year’s Computex and officially launched in January this year, the Plextor M9PE Series comes in three form factors: the naked M.2 form (M9PEGN), M.2 with heatsink (M9PE(G)), and the PCIE version (M9PE(Y)). Let’s take a look at the last model.
A glimpse of it, one could quickly assume that the M9PE(Y) is an expansion card similar to a sound card or a USB adapter. The card’s side that should face the rear slot openings of a PC casing simply consists of a metal grille. Meanwhile, the entire front side of the printed circuit board (PCB) is clad in a metal chassis with “fins” as part of the design. This chassis can be removed by taking off the screws, underneath of which a rubber pad directly touches the M9PE(Y)’S SSD card. The rubber pad, metal chassis, and the grille all work together to cool the SSD passively.
The M9PE(Y)’S SSD card is basically the M9PEGN. It is attached to the M.2 slot on the card which has a PCIE 3.0 x4 interface. There are four prominent chips present on the card: the Marvell 88SS1093 controller, Nanya 1708 NT6CL128M32BM-H2 LPDDR3 512MB DRAM cache, and a pair of Toshiba TH58TFT1T23BEF 256GB NAND flash memory chips.
Before we proceed to the benchmark results, here are the components that we employed to test the M9PE(Y): an MSI B250M Bazooka Opt Boost motherboard, Intel Core i7-7700 processor, MSI GTX 1050 Ti Gaming X 4G graphics card, 2x G.SKILL Trident Z RGB 8GB DDR4 memory modules, and a CM MWE 650 Bronze PSU. Scores were compared to those of SATA 6Gbps SSDS which we already reviewed, namely the ADATA SP920SS (256GB) and the Plextor S3C (256GB), both of which were retested using the components that were mentioned.
Beginning with Anvil’s Storage Utilities, the M9PE(Y) registered a sequential read speed of 2569.64Mbps, sequential write speed of 661.93Mbps, 4K read speed of 58.9Mbps, and 4K write speed of 1.56Mbps. Taking note of the same benchmarking units, the M9PE(Y) remained consistently fast in Crystaldiskmark (2418Mbps, 1982Mbps, 64.3Mbps, and 206.6Mbps) and in AS SSD Benchmark (1985.39Mbps, 741.04Mbps, 42.22Mbps, and 6.12Mbps. While the SP920SS and the S3C got impressive scores in these benchmarks, they were easily overshadowed by what the M9PE(Y) got.
As a storage solution for gaming rigs, the M9PE(Y) can deliver on its promise, ensuring that the OS, games, and other heavy apps will launch quickly. Just make sure that your board has an extra slot for this speed demon.
