Voor bikkels met teveel geld heeft 3D Alpha een review geschreven van de Adaptech AAA-131U2, een U2W SCSI RAID controller met 3 kanalen die het mogelijk maken om maximaal 45 devices aan te sluiten. Ondersteund worden de RAID levels 0, 1, 0/1 en 5:
The first thing I wanted to look at was the card itself. I had never seen, held, or used a RAID controller in my life before, and I was curious. One thing I noted on the AAA-131U2 card is that is has a slot for a RAM DIMM, so the memory on the card is upgradable. Memory does come with this card, but it's only two megabytes of DIMM memory to work with, although it can support up to a 64 megabyte DIMM. (DIMM Compatibility List for Adaptec RAID cards.) The AAA-131U2 card fits in a half-length 32-bit PCI slot, and it has three channels of SCSI output: One channel is an Ultra2 Wide 68-pin SCSI connector, a standard Ultra SCSI 50-pin connector, and the last one is an external Ultra2 Wide 68-pin connector. You can also daisy-chain several external Ultra2 devices, so long as you terminate the last one. You can even use the external connector to connect an entire array enclosure to the RAID card. Also, if you're planning on using your SCSI drives more often than your IDE drives (Or entirely over your IDE drives.) You can take the LED connector off your motherboard and attach it to the AAA-131U2 card. Though, attaching a cable to the RAID card is completely optional, but it could be quite useful if you feel it necessary for your LEDs to indicate SCSI activity.
Helaas in de review geen harde benchmarks die de performance van een RAID config met een single SCSI of ATA66 schijf vergelijken.
