Anand heeft een review over de Promise Utra ATA/66 Controller.
Ultra ATA/66 (you'll also hear it referred to as Ultra DMA/66 or Fast ATA-2) allows for a theoretical maximum burst transfer rate of 66.6MB/s, double the maximum of Ultra ATA/33's 33.3MB/s. Another change brought about during the introduction of the Ultra ATA/33 specification was the idea of Cyclical Redundancy Check (CRC) which is something that you've all probably heard of in one form or another at sometime during your computing experience. Basically, before any burst transfers take place both the hard drive and host will calculate what should make it through the transfer and then afterwards the host sends a signal back to the hard drive telling it what actually made it over during the transfer. If the two numbers don't match up then the process is automatically repeated until it is completed successfully. Ultra ATA/66 brings the same CRC feature that Ultra ATA/33 brought to the table, couples it with its 66.6MB/s theoretical burst transfer rate, and adds yet another new feature to the growing list: improved data integrity.
Uiteindelijk maakt het voor snelheid onder windoos geen donder uit of 'ie nou met een Ultra ATA 66 of Ultra ATA 33 werkt.
