![]() The controller uses low-density parity check (LDPC) code to increase the endurance of the Toshiba 15nm TLC. The two largest models share the same high-performance specifications, but the 128GB model loses some of its reputed performance due to fewer available flash packages for parallel operations.Ī Marvell Dean 4-channel controller is at the heart of the M7V. The 512GB model we tested has a native TLC 128KB sequential write speed of 210 MB/s, which we discovered during our testing, but the SLC buffer increases write performance for short, bursty write traffic. Performance data from Plextor comes with an "Up To" prefix, and the M7V series uses Toshiba 15nm Toggle Mode TLC flash with an SLC buffer. Plextor already released the M7V series in an M.2 2280 model, but it still uses the SATA 6Gb/s interface. The red SSDs carry a premium over the standard drive, which comes in a natural brushed aluminum finish, but the performance specifications and capacities are the same. Plextor released the M7V in 128GB, 256GB and 512GB capacities, and some retailers also carry the M7V special edition in a bright red case.
