These are going to be used for recording national acts at concerts around the US. When you say ‘decent’ I get kind of scared. I need to buy 20 of them, and need the best / sturdiest/ durable and reliable I can find. We had issues last year with 5400 rpm drives while doing the New Orleans Jazz Festival that caused real failures and that is why we are shopping. we have had no issues with 7200 rpm drives (Western Digital or LaCie).
