The 3TB Seagates were bad; the other capacities were much better. But the design of the 3TB ones*might* have improved since. I have a bunch of 2TB "Desktop" Seagates running 24/7 in a FreeNAS machine. One -- an older model that came with a 5-year warranty -- failed and was replaced by a newer model (one that normally comes with only a 2-year warranty but carried the remainder of the original 5-year warranty). One of the newer models (out of warranty) showed a read error but was "fixed" by SeaTools and now, even after an extensive workout (HD Sentinel PRO's 34-hour read, write, read), shows no errors. If you read the NewEgg reviews, you will find that for *every* brand of hard disk there are people who will never buy one of that manufacturer's products again. Perce
