The overall Newegg rating for the Syba card you deride is 4/5 eggs across 109 reviews. If the card was as horrible as you make it out to be, the rating would be 1/5 not 4/5, and people would stop buying it. Note that the user who posted the read corruption issue referred to a single application in Windows 7 where this error occurred, TeraCopy. It's far more likely he was up against an application or driver issue than a hardware issue with the Syba card. He did not state whether a Windows Explorer copy would also cause the problem, nor xcopy, nor Robocopy, etc. BTW, did you even read the BackBlaze blog I posted? They run hundreds of this exact Syba 3132 card, with Linux, with mdraid, and have reported zero problems. And they're using a 5:1 PMP on each 3132 port. If these cards, or the 3132 were junk, as you state, surely BackBlaze would have run into problems in 2+ years of full production, no? Again, you're taking isolated incidents and assuming they are the norm, when they most certainly are not. -- Stan
