The new 2.5-inch MasterDrive OX drives employ multi-level cell (MLC) memory, which has traditionally been inexpensive but slower, and features read speeds of 150MB/sec and write speeds of 100MB/sec. While the OX SSDs are not breaking any speed records, their price is certainly appealing. An entry 32GB drive will cost you $149, while higher capacity 64GB and 128GB models will set you back $259 and $419 respectively.
The MasterDrive PX, on the other hand, uses SLC NAND Flash to deliver the best possible reliability and performance. These drives will be available in capacities of 32GB or 64GB, for $499 and $849, and are capable of 170MB/sec reads and 130MB/sec writes. The new drives are expected to be available later this week.
