25nm NAND flash-filled m4 SSD, which it has priced at the reasonable level of $130 for a 64GB unit. The company describes it as the fastest drive it has yet introduced, and although early reviews pointed out it'd lost something in read speeds relative to the previous generation, the new m4's improved write speeds and general performance should certainly make that a compelling entry price. More ambitious archivists will be looking to the 128GB and 256GB models, priced at $250 and $500, respectively, while those without a budget will also be given the option to splash $1,000 on a 512GB m4 SSD. All four varieties come in a standard 2.5-inch form factor, support 6Gbps SATA transfers, and are rated to reach read speeds of 415MBps. Availability is immediate and worldwide, so hit the Crucial link below if you're keen on getting one for yourself. Full PR after the break.
