ArecaTechnology Corporation SAS Controller ARC-1883I

Upgraded from an old ARC-1220. This dropped right in and saw my raid volumes. Driver was also the same. (Also had to buy new cables).More than twice as fast. Not exactly sure how much faster as I don't remember the Crystaldisk numbers on the old controller, but they were a lot lower.The first rebuild I did on this controller took 8 hours compared to 28 on the ARC-1220 (5 x 4Tb spinning drives, a 16Tb array).
