The budget MasterDrive OX uses multilevel cell NAND flash and has data speeds of up to 150MB per second in sequential read and 100B per second in sequential write, according to the company. The MasterDrive OX comes in capacities up to 128GB and has a 1-year warranty.
The higher-end MasterDrive PX, on other hand, uses single-level cell NAND flash and focuses on the reliability and endurance, rather than capacity. It, too, is supposed to have lightning-fast sequential read and write speeds, up to 170MBps and 130MBps, respectively, according to STT. The MasterDrive PX SSDs are available in 32GB and 64GB capacities, and comes with a 3-year warranty.
Both drives use standard 2.5-inch SATA-II interface and will be available later this week. The 128GB MasterDrive OX has a street price of about $419, which is about the same as the new SSD that. The MasterDrive PX, on the other hand, is much more expensive, costing $499 for the 32GB version and $849 for the 64GB version.
