Crucial Starts Selling MX500 2.5-inch SSDs

Crucial started selling all four models of its premium SATA SSD, the MX500. The drive was launched earlier this month. It comes in 250 GB, 500 GB, 1 TB, and 2 TB variants; and in the 2.5-inch form-factor, with SATA 6 Gbps interface. M.2-2280 variants with SATA interface, which were shown off at the 2018 International CES, could launch a little later this year. The 250 GB variant is priced (MSRP) at USD $79.99 ($0.31 per GB), the 500 GB variant at $139.99 ($0.27 per GB), the 1 TB variant $259.99 ($0.25 per GB), and the range-topping 2 TB variant $499.99 ($0.24 per GB). All four models come with 5-year warranties.

Crucial MX500 combines Micron's 2nd generation 64-layer 3D TLC NAND flash memory with a Silicon Motion SM2258 controller, and a custom firmware by Crucial. The NAND flash chips by design offer the same levels of power-loss protection as drives that need capacitor banks to do so. Among its features are Dynamic Write Acceleration (SLC-cached writes), and Redundant Array of Independent NAND (RAIN). All four variants offer sequential transfer rates of up to 560 MB/s with up to 510 MB/s writes, and 4K random access performance ratings of up to 95,000/91,000 IOPS (reads/writes).
