Been finding some good deals on 2.5 disks lately, but have never bought one before. Have a couple of 3.5 disks on the other hand in my Unraid server. Wondering how much it matters wether I get a 2.5 or not? What form factor do you prefer/usually go for?
Smaller stuff has to be more complex to get to the lower mass, which is usually what causes the biggest issues. The hdds in those ipods had some extra stuff to make them more reliable, but even then, move them too quickly and they show it.
Smaller doesn’t need to be more complex. 3.5" drives weren’t more complex than 5.25" drives.
A smaller head means a smaller drive actuator. Less mass and smaller size means it can compensate much quicker in response to vibration detection.
Back when full height 5.25" drives were the norm, you couldn’t pick up your PC while running without causing an error. Those tiny CF card sized drives failed but took extreme abuse compared to big drives.
