The heart of the performance of the Intel 520 series drive is the LSI Sandforce 2281 NAND controller. Intel partnered with LSI to develop a robust firmware specifically for this drive. Along with the firmware are AES 256-bit encryption and end to end data protection. Specifications for the drive mirror many of the Sandforce 2281 controlled drives with 550 megabytes-per-second (MB/s) sequential reads and up to 520MB/s sequential writes and 4 KB random reads and writes up to 50,000 and 80,000 (IOPS).
