Recensione controllers RAID ATA 100.

In conclusion we would like to point out that despite relative low results (compared with those shown by SCSI systems), all controllers cope with their task successfully: they create fault tolerant storage subsystems with large storage capacity and of relatively low cost. Now the market offers really good HDDs with perfect price-to-capacity ratio, which will suit ideally for a storage subsystem capable of competing with a SCSI one at least in terms of pricing. For instance, RAID 5 configuration built of three IBM DTLA 307075 HDDs, one IBM DTLA 307075 as a hot spare drive and an IDE RAID 5 controller will cost around $1600 altogether. A system of two Seagate Barracuda 180 HDDs and a controller will cost at least twice as much. Therefore, these controllers really offer us a great opportunity to save. Which can't remain unnoticed. In fact, we are about to very soon see a new generation of IDE RAID controllers. Adaptec announced the launching of their new ATA RAID 2400A (for 4 HDDs, supporting RAID 0, 1, 01, 5), which will be equipped with a faster I/O chip - i960RS. Promise announced the upcoming external IDE RAID UltraTX4 and TX8 systems for 4 and 8 HDDs respectively equipped with a SCSI-to-ATA Bridge, by the way, which will allow connecting them to any Ultra2 LVD SCSI controller with an ordinary 68-pin LVD cable. We believe there will be also an internal version some day.
