1.5Tb is tempting, but... When Seagate came out with the 750Gb hard drive I purchased 8 of them: 5 ATA's, 3 SATA's, Only 1 still works! It's been a year and a half. I will wait until someone who cares more about quality and less about size makes something comparable. My data is too important to trust to another Seagate pruduct.
