OCZ is expected to introduce its Enyo USB 3.0 solid state disk by mid-May. This device will ship in capacities of 64GB, 128GB and 256GB, and the faster models promises read speeds of up to 260MB/s and write speeds of up to 200MB/s. Pricing is expected to be in the range of the SandForce-based Vertex 2 SSD, likely slightly higher.
The OCZ Enyo will be available in 64, 128 and 256GB capacities and all three drives use MLC NAND flash memory, have 64MB of on board cache and USB 3.0 Micro B connector interface.
Since we are talking about a USB 3.0 SSD-based external drive, you can expect speeds of up to 260MB/s for read and up to 200MB/s for write, with sustained speeds of up to 150MB/s for 128GB and 256GB versions. The 64GB one will have a bit lower speeds of up to 225MB/s for read and up to 135MB/s for write with sustained write of up to 40MB/s.
