I loved and owned quite a few 2.5" HGST travelstars. There were capably of takig insane abuse and worked just fine. Interestingly enough I never got to buy the 1.5TB ones; by the time I needed one it disappeared off the market, the website, everywhere. I never knew why. 192 Power-Off_Retract_Count 0x0032 100 100 000 Old_age Always - 2502492302 193 Load_Cycle_Count 0x0012 086 086 000 Old_age Always - 142654 ^^^ those are a working, happy disk; all due to a "feature" that was on in Ubuntu by default that wanted to idle/spin down the disk every other second and it took me a while to notice. On contrary I'd worn a 2TB 2.5" Seagate out in 2 years. Bought it new, put it in the same machine the 1TB HGST had been running for 3 years already, the Seagate died earlier - or at least that's what ZFS told me. It's spinning, but it throws weird errors from time to time. I never had experience with 3.5" Hitachis. Eons ago there were some interesting disks in the market though; if I remember correctly my father had some Fujitsu SCSI160 or 320 drives which had their normal working temperature around 50-60C.
