Equipped with 256GB of toggle-mode NAND flash managed by an LSI Sandforce 2281 controller, the Chronos Go Deluxe delivers excellent performance across the test spectrum. Rated to deliver read/write speeds of up to 560MB/sec read and 520MB/sec write, the drive meets or exceeds these performance parameters. Performance degradation over time should prove minimal with the drive supporting the TRIM command, if the operating system supports it, and 16GB of over-provisioning that reduces the capacity of the drive to 240GB; a common practice with SandForce controlled drives. Delivered with an MTBF rating of 2 million hours, or just over 228 years, you can reasonably expect the Chronos Go Deluxe to last well past the three-year warranty period. Outside of the pricing, I can say this drive performed up to expectations delivering its rated performance and then some more!
