Intel has released a new version of its Solid-State Toolbox software bringing it up to version 3.0. Solid State Hard Drives have a limited number of times that they are able to rewrite data onto their NAND flash cells. Out of the most common 20nm MLC NAND flash you can expect around 5,000 write cycles although this can vary by brand and chip design. The Intel software monitors your Intel SSD for performance degradation, and provides a measure of how many rewrite cycles are left, so you can plan beforehand about backing up your data and replacing it. The software also provides a suite of diagnostics for your Intel SSD. Lastly, the software can update your drive's firmware without the need for a DOS bootable disk.
