Intel Solid-State Drives (Intel SSDs) just got better. Thintel_ssd-320.jpge next generation Intel SSD 320 Series offers built-in data protection features, better performance, larger capacities and more value for your money.

Built with 25 nanometer (nm) compute-quality Intel® NAND Flash Memory, the Intel SSD 320 Series accelerates PC performance where it matters most. With random read performance up to 39,500 Input/Output Operations per Second (IOPS) and sequential read performance of up to 270 megabytes per second (MB/s), your PC will blaze through the most demanding applications and will handle intense multi-tasking needs. Couple that performance with random writes up to 23,000 IOPS and sequential writes up to 220MB/s to unleash your system.

Superior built-in data protection features

The new Intel SSD 320 Series contains built-in features to protect your data from external threats and internal system snags.

The Intel SSD 320 Series comes pre-configured with Advanced Encryption Standard (AES) 128 bit encryption capabilities. In the event of theft or loss of your computer, you have the peace of mind that your personal data is secured by advanced encryption technologies.

Additionally, two new data protection features guard your data from internal system mishaps. To reduce potential data loss, the Intel SSD 320 Series detects and protects from an unexpected system power loss. The drive saves all cached data in the process of being written before shutting down, thereby minimizing potential data loss.

The Intel SSD 320 Series also improves reliability by providing an array of surplus NAND flash. If the controller encounters a faulty NAND array, the Intel SSD 320 Series automatically reconfigures itself to reduce the prospect of data loss.
