Plextor's newly launched M5 Pro is angling to be the top dot on the SATA III SSD spec charts -- and looks like it will mostly succeed. The Marvell Monet controller lets the unit hit a continuous 540 MB/s read and 450 MB/s write speeds for the larger models, as well as a hefty 94,000 read and 86,000 write IOPS. Those figures would put it ahead of or alongside most of its competitors except in steady write speeds, but Plextor claims that hustle is not the model's only trick. It also makes use of "True Speed" tech to minimize performance drops with age, uses 128-bit error correction to eliminate data inaccuracy and offers 256-bit full-drive encryption. The 128GB, 256GB or 512GB drives will be available mid-August for prices that have yet to be determined, but it's likely to be well north of its budget namesake, the M5S. You'll find the full PR after the break.
