Could be Petrol SSDs...! What exactly you mean Malfunctioned?
OCZ's are good drives .. I used OCZ before Corsair and my Brother still using OCZ ...we have no issues at all....
Both SSDs failed to get detected in BIOS. I tried various MoBos but they didn't get detected on any.
I too feel OCZ to be good brand for SSDs and thats why I opted for it. But I think their Petrol drives are not upto the mark.
