Tweakers.net check out nine RAID 5 capable SATA adapters. I run a Promise FastTrack S150 SX4, which judging by the results is a bit out of date now.[The review]More or less the same applies to the Promise FastTrak S150 SX4. A year ago it would have been a nice solution if driver issues wouldn't have spoiled the party. The performance of the FastTrak S150 SX4 has been completely overthrown by the newcomers from Areca, HighPoint and RAIDCore. The SX4's low price per port is no longer an advantage now that the 8-port RocketRAID 1820A can be bought for a price-premium of only 60 euros.
