I gave up on G-Raid a few years ago after problems and lackadaisical support.
After that I moved to Caldigit and have no complaints.
That said, neither g-raid or caldigit make hard drives - just the enclosures. It could just be a bad run of drives. The real issue is how the enclosure company deals with it.
I'm really sorry to hear about the ownership change. I bought my first in 2006 and it was great. I chalked up three bad G-Raids from Amazon sellers to the G-Tech tech support guy today and I sensed his jaw went limp. There wasn't much he could say to me. All returnable through Amazon.
I don't know why, maybe it's my concept of costs, I'm sticking with G-Tech and buying from B&H. I don't know if I could easily swap in a Caldigit. I've heard about larger RAID arrays. They sound expensive.
There's also the G-drive I mentioned. Sleep problem. He said he expects a firmware update for that. So I'm hanging on.
Considering what I've gone through, I feel very unfortunate, as well as quite nuts.
