Important SSD notes: Solid State Drives DO NOT require defragmentation. It may decrease the lifespan of the drive. Consumers may see a discrepancy between reported capacity & actual capacity; the storage industry standard is to display capacity in decimal. However, the operating system usually calculates capacity in binary format, causing traditional HDD & SSD to show a lower capacity in Windows. In the case of SSDs, some of the capacity is reserved for formatting & redundancy for wear leveling. Rated speeds may vary slightly depending on the benchmark used, drivers, windows version, bios version & file size. We recommend using ATTO, IOMeter, & PC Mark Vantage for benchmarking SSDs & to achieve maximum rated specifications. Maximum performance is achieved by using the P67 chipset with Native SATA 6 Gbps.
