September 24, 201114 yr Author Just had a brain wave. I wasn't sure which drive I had moved off of the multiplied ones onto the SIL3132 card. Turns out it was chache! That's fine being on the multiplied ports I guess because its not gonna be used during parity syncs. Speeds can still drop to around 20MB/s but I do see 70MB/s at times! Guess the only way fully around it is to buy a new mobo or a SATA card. Do the SuperMicro PCI-E 4x 8 port cards suffer from poor performance or should I get 50MB/s+? Also would a 4x card work ok in a 16x slot? I think I searched before and someone said it should. Anyway big thanks to bcbgboy13
September 25, 201114 yr The Supermicro 8-Port SAS/SATA Card (AOC-SASLP-MV8) does not has performance issues. It may be the most commonly used HBA card in unRAID.
