The SLW-M series is Sony's first foray into the consumer SSD market. They're 2.5-inch form factor drives measuring 7mm thick with a SATA 6Gbps interface. Initially there was no mention of what controller or type of NAND flash memory chips Sony opted to run with, but a teardown of one of the drives by Chinese-language website reveals that Sony paired Toshiba's A19 TLC chips with a rebranded Phison S10 series controller.

Sony's kicking things off with two capacity options, 240GB and 480GB. They're rated to read and write data at up to 560MB/s and 530MB/s, respectively, though it's not clear if both drives sport the same rated performance or if those figures are combined maximums (performance tends to vary by capacity).

This isn't a high performance line, though the rated specs would have been top notch before the emergence of PCIe-based SSDs. It will be interesting to see how pricing shakes out, along with real-world performance metrics.

It's not yet known when the drives will be available or for how much. What is known is that the retail kit will come with a 9.5mm spacer, Acronis True Image 2015 HD, and Sony's own SSD Toolbox drive management software.

The product is also known as SLW-MG2, SLW-MG2/T SYM, SLW-MG4, SLW-MG4/T SYM
