Plextor is bringing to market a next-gen SATA III SSD powered by Toshiba BiCS 64-layer flash. The M8V is designed as a value-oriented legacy storage device that can deliver MLC like performance on a TLC budget. The M8V will be initially offered in two form factors and three capacities. We don't know if larger capacity points will be offered in the future, but for now, the M8V Series tops out at 512GB.
Plextor has once again teamed up with Silicon Motion for the M8P Series. Powering the M8V is SMI's venerable SM2258 SATA controller. Silicon Motion's 4-channel SM2258 has become a favorite of ours because it is chock full of advanced features and more importantly delivers outstanding performance.
Of all the features listed, Silicon Motion's NANDXtend technology is the most important for TLC SSDs. NANDXtend is SMI's proprietary LDPC (Low Density Parity Check) bit correction technology. This technology is essential for TLC (Triple Level Cell (3-bit)) powered SSDs because it extends the endurance of low P/E cycle flash by as much as 3x over conventional bit correction technologies. With NANDXtend, TLC flash arrays are capable of endurance that is at or near MLC (Multi Level Cell (2-bit)) levels. In addition to LDPC bit correction, the M8V Series the M8V supports RAID Engine (Drive Array Accelerator) and Data shaping (Data management) for enhanced data transfer stability.
Plextor are sticklers for quality control, and like all Plextor SSDs, the M8V is subjected to rigorous inspections from Plextor's world-class advanced SSD testing laboratory thereby ensuring error-free performance for the lifetime of the drive. Plextor's quality control testing simulates a wide range of professional read-write scenarios, verifying that your Plextor SSD will deliver expected performance while remaining error-free under the most rigorous circumstances.
To further enhance your SSD experience, the M8V features PlexNitro SLC (Single Level Cell (1-bit)) buffer technology. PlexNitro, enhances both the performance and endurance of the M8V. The M8V Series also supports three of Plextor's exclusive SSD applications. PlexTurbo (Smart Cache) effectively reduces the number of write access on the SSD resulting in extended service life. PlexCompressor (Smart Compression) automatically compresses files that have not been used for more than 30 days, providing more available storage space. PlexVault provides a secure storage area allowing your private/sensitive data to be hidden from prying eyes. In addition, Plextool, a proprietary SSD Toolbox, provides an easy to use interface to monitor status, update firmware and diagnose the drive for data integrity and security.
Let's get the M8V on the bench and see for ourselves exactly what kind of performance the M8V will deliver.
