3XFR RAID 0/1/3
3XFR
THE PERFECT TOOL FOR HIGH PERFORMANCE REQUIREMENTS

RAID 0 = PERFORMANCE
The ultimate performer, the 3XFR is capable of tripling the drive throughput speeds up to the limit of the host Ultra SCSI channel (40 MB/Sec). In fact, with three of the latest 10,000+ RPM drives from Seagate, the 3XFR has been measured at throughput rates in excess of 35MB/sec over the full capacity of the drives. This performance is made possible by striping across three Ultra SCSI (40MB) drive channels to 3, 6, 9, or 12 drives. A user can obtain sustained data throughput rates in excess of 25MB/sec over the full capacity of the drive making use of the much less expensive 7200 RPM drives.

RAID 1 = THE ULTIMATE IN DATA PRESERVATION
The 3XFR, in its RAID 1 mode will write a duplicate (mirror) drive for each data drive. As in RAID 3, if one drive fails, the system will continue to operate normally. When the failed drive is replaced, the 3XFR rebuilds it automatically. Unlike RAID 3, each drive of a mirrored set contains all the data for that set. If the user were to want to construct another system with the same data, all that is necessary is to move one of the drive sets to the new system and run. When the removed set is replaced, by new drives, they will be rebuilt by the 3XFR automatically.

RAID 3 = PERFORMANCE WITH REDUNDANCY
The 3XFR will effectively double the throughput rate of a single drive in RAID 3 while recording redundancy information on the third drive such that in case of a failure of any single drive, the data will not only be preserved, the system will a continue to function normally. When the defective drive is replaced, the system will rebuild it automatically. The internal high speed logic of the 3XFR accomplishes this task by efficiently striping the data blocks across two of the 3 drive sets. At the same time, it calculates parity information and records it on the third drive.
