I wouldn't touch Toshiba hard drives with a 100' pole.
In my lab, Toshiba Enterprise class 2.5" (146GB, 15k rpm) hard drives compose right around 1% (9 machines, 2 with two trays, 17 drives per tray for 187 drives) of my drive population, and for the last 3 years have been over 40% of my hard drive failure rate. This is out of just under 20,000 drives, and including Seagate and Hitachi 1TB and 750GB drives that are older than 5 years, while these Toshibas are less than 3 years old. Yet, these Toshiba drive fail at such a rate that they outnumber any other drive type. I get from 2 to 8, mostly 3 or 4, Toshiba drives fail per month. These are supposed to be Enterprise level drives with a lower failure rate than standard desktop drives.
I am certainly not going to go for their desktop or laptop drives with that kind of a record on drives that are supposed to be more reliable. These things must have an absolute horrid failure rate.
