Toshiba drives are very good. In fact among 2.5" models I'd say they are the most reliable out there. Part of this has to do with their architecture and the fact that all adaptive information is stored in a ROM chip on the PCB rather than storing it on the platters like most other drives do. It makes them immune to most firmware issues which is a leading cause of failure with many models.
As to their 3.5" drives, most Toshiba desktop sized drives are actually HGST drives. HGST, though it is owned by WD is built using Hitachi architecture and they are very solid drives. HGST is generally accepted to be the most reliable of the 3.5" models. So, by all means, Toshiba drives are great quality.
I work in data recovery and we always return data to customers on Toshiba drives if they buy them from us. Otherwise we run the risk that people will expect a free recovery when a drive we sold them fails.
As to other brands of hard drives, here goes...
WD is pretty good.
Seagate is complete crap for all newer drives.
Samsung is OK if it's actually a Samsung you're getting, but many are actually Seagate garbage in disguise, so you have to know what model you're actually getting.
HGST are the best for 3.5" and make very good 2.5" as well.
Toshiba makes the best 2.5" drives, most 3.5" Toshiba branded are actually HGST, but they have recently started building some of their own. We'll have to wait and see how good their own 3.5" drives actually are, but I suspect it'll be good.
