This drive is the first 2.5-inch enterprise disc drive, making possible a new class of high I/O, high-density storage solutions. These drives enable space-constrained data centers to achieve higher IOPs (input/output per second) performance in small form factor system configurations while maintaining the highest levels of reliability.
