659331-001 HP Smart Array P220I Controller With 512MB Flash

The HP Smart Array P220I Controller is designed to support SAS (Serial Attached SCSI) and SATA (Serial Advanced Technology Attachment) hard drives with a data transfer rate of up to 6 Gb/s. It supports RAID levels 0, 1, 10, 5, and 50, which allows for data redundancy and improved data access times. This controller comes with 512MB Flash Back Write Cache, which is a type of cache memory that temporarily stores write data to the disk. This helps to improve the performance of the RAID system as it reduces the amount of time it takes to write data to the disk.
