Is there such thing as the larger the space of a harddisk, the easier it is to spoil?
by space i mean the original space that it has when you 1st bought it. Not how much space is left in it

the reason how i come out with this is i have a 1TB internal WD green cavier HDD. but it spoilt in 2 years.
Whereas my Seagate internal HDD 160GB is still good. ands its more than around 2.5 years already
An IT shopkeeper advised me to use 1Tb rather than 2Tb, coz the latter spoilt easier; I thought, nonsense if that's really the case, then 2Tb and now 3Tb wouldn't be selling well, I thought he just wanna clear his 1Tb hdd stock. But after that, my 2Tb WD Caviar Green was spoilt before 1 year, my friend's 2Tb WD Caviar Green (newer model) spoilt after few days use ... this made me re-examined my thoughts.

Consequently, after reading some online articles, I guess we've taken for granted that modern internal SATA hdd still need good care especially when connected to the PSU. Nowadays, I guess some of us simply connect the power supply rails to multiple internal hdds in our rig. I think but not 100% sure, that bigger sized hdd requires more power, or ampere/current to be precise, to run nicely. 2Tb should have more platters than a 1Tb hdd, or something like that. So, the smaller sized hdd might get away with smaller ampere or lousier PSU, thus could survive longer. But to be safe, we shouldn't use the same power cable/rail with two hardisk or devices, separate them; and don't feel bad about buying a good expensive power supply unit, it's a must in fact. To think of it, why buy expensive mobo, gc, cpu, hdd if the psu is cheapo and could cause all the other expensive components to malfunction?

- If you notice that one of your hard drives suddenly goes kaput, 99% of the time, it's because the 12 volt rail is running too low on amperage to power it properly. The same goes for CD/DVD drives that suddenly start mass producing coasters. Your 12 volt rail is being taxed so heavily (usually by your new GPU or some similar power hungry device), that your other 12 volt devices are suffering because there aren't enough amps to go around after your massive 8800GTX sucked up all the amps from the 12 v rail! Hard drives are especially vulnerable to death because of amp inadequacy on the 12 volt rail. If they don't get the right amount of amps to write data, then they will most likely cause the HD head to smear the platters and cause irreversible, physical damage to the disk.
- +12v - This is the main rail on your PSU. It powers everything else in your computer. This includes your main processor, its fan, your case fans, hard drives, optical drives (i.e. DVD/CD±RW), add-on cards, your PCI-Express lanes, the GPU, your sound card.... everything else. Your PSU may have one or more +12v rails. All molex (4 pin) connectors run from the 12v rail.
- Rail - Every power supply carries anywhere from 4 to as many as 9 rails. Each rail is rated for a specific voltage, and will always carry that voltage no matter how many devices are connected to it. However, each rail has an AMPERE RATING. The more devices you connect to each rail, the lower the available amperage to the rest of your computer system on that specific rail.

So, nowadays, I'll remind myself to separately connect the power rails to each of my hdd, even tho the extra cables (my psu is modular) blocks the airflow and looks messy. I hope this precautionary step would prolong my hdds lifespan so that they wouldn't prematurely die before their mtbf. We'll see how this goes in .... another year; I'll try to update. (Yeah, I know this is computer common sense, and I did practise it long time ago, but like I said, I took it for granted after a while.
