Example took me less than 64 seconds to find (for Seagate Barracuda IV): http://www.seagate.com/cda/products/discsales/personal/family/0,1085,559,00.html Look for 'Avg. Sustained Transfer Rate'. AFAIK, every manufacturer I know gives the sustained transfer rate specs (which are sometime a bit too high than in reality). If the specs are not specified, it'd be very suspicious, and I would think 128 time before buying such drives. 31.07.2003; 18:28:06 [SorAlx] http://cydem.org.ua/
