For enterprise PC usage(e.g. servers), a minimum of 6.7% over-provisioning (OP) is required and can be set through Magician.
* Sequential performance measurements based on CrystalDiskMark v.3.0.1. Random performance measurements based on Iometer 2010. Performance may vary based on SSD’s
firmware version, system hardware & configuration.
** Power consumption measured with MobileMark 2007 in Windows 7. Values calculated using laptop computer and represent system-level power consumption.
*** For enterprise applications, 5 years limited warranty assumes a maximum average workload of 40GB/day (calculated based on host writes and on the industry standard of
3-month data retention). Workloads in excess of 40GB/day are not covered under warranty.
