Which is why most folks who buy substantial numbers of drives do something like this: 1. Decide what drives[1] you like and take proper statistical history into account. The answer is often somewhat random and more about "I like" rather than "I know for a fact". 2. Buy those drives. 3. Establish a relationship with that vendor. 4. If step #2 goes south and you got duds, get replacements leveraging on #3 But asking a random bunch of dudes on a mailing list "what is a good drive right now" is a useless question. If the mailing list is big enough there are only two eventual answers: - any of them - none of them [1] This can be 0, 1 or more drive types -- Alan McKinnon alan.mckinnon@gmail.com
