The Agility 3 Series implements the cutting-edge SATA 6Gbps interface to deliver excellent sequential and random data transfer rates, significantly improving your computing experience over hard drives. In addition to enhanced performance, an Agility 3 upgrade promotes cooler, quieter, and more energy efficient conditions compared to traditional mechanical hard drives. With no moving parts, SSDs provide peace of mind with their superior durability and reliability. Unique and innovative, Agility 3 SSDs deliver a one-of-a-kind storage solution. 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 and 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 and SSD to show a lower capacity in Windows. In the case of SSDs, some of the capacity is reserved for formatting and redundancy for wear leveling. Rated speeds may vary slightly depending on the benchmark used, drivers, windows version, bios version and file size. We recommend using ATTO, IOMeter, and PC Mark Vantage for benchmarking SSDs and to achieve maximum rated specifications. Maximum performance is achieved by using the P67 chipset with Native SATA 6Gbps.
