So I'm in the market for some storage hard drives, so backup my media and/or lanning. Now I want to know does the RPM really matter? Cause as far as I can make out it only matters when the drive is used for gaming/programs.
Also has anyone found a 2TB 7200 being sold anywhere? Preferably Seagate. Thank you :)

Looks more than adequate for your purposes:
Spin Speed (RPM) 5900 RPM
Sustained data transfer rate 144Mb/s
Average latency 4.16ms
Random read seek time <12.0ms
Random write seek time <13.0ms
I/O data transfer rate 600MB/s
Unrecoverable read errors 1 in 1014
I while back I looked at this as well and decided to go with Western Digital Green drives. Low speed, less power and great transfer speeds.

It's actually beneficial to use the lower-RPM drives for storage, since they generate less heat.

Agreed, heat is nobody's friend. And if you can save some power to it's a win-win.

I've had bad experiences with this series. WD's are usually pretty rock solid, but the Green series has been quite unreliable in my experience, quite a few failures.

hmmm, so given the recent replies to this thread, seems like it doesn't really matter about the rpm speed?
will look around for the SMD (http://poradnik.telewizor.eu/lutowanie-smd.html) WD's then :)

I got one from TVR end of last year [www.tvr.co.za] - was dirt cheap.

Opposite for me, find them reliable,*knocks on wood. Got 5x2TB purchased the first two the day they landed in SA

Neither, go for Samsung EcoGreen. Cheaper and cooler and may very well be faster judging from some comments here.

never going Samsung I need these drives to last, had way too many bad experiences with Samsungs :(

Interesting, as I'd go with the Samsungs and stay away from the WD Green. As I've said before it boils down to luck of the draw, any drive can fail any time. If you look after your drives then, if luck is on your side then you should have an equal chance with any brand of drive.

It's all about luck hey.
So seeing as the WD Greens have well documented problems, seems you're left with the Seagate.
Reconsider the Samsung though. People have been raving about them and they've taken a huge market share since 2 years or so ago.

The F4 2TB is the one. Speeds up to around 70MB/s IIRC.

http://en.wikipedia.org/wiki/Hard_disk_drive
A common misconception is that a colder hard drive will last longer than a hotter hard drive. The Google study seems to imply the reverse—"lower temperatures are associated with higher failure rates". Hard drives with S.M.A.R.T.-reported average temperatures below 27 °C (80.6 °F) had higher failure rates than hard drives with the highest reported average temperature of 50 °C (122 °F), failure rates at least twice as high as the optimum S.M.A.R.T.-reported temperature range of 36 °C (96.8 °F) to 47 °C (116.6 °F).[64]
I read they study, VERY interesting, it pretty much sums up that regardless if the drive is a cheapie drive, or EXPENSIVE server grade drive, failure rates are the same.
Google answer, triplicate the data

For those that want a review of the study, and link to the study

What?
After all seagates firmware issues and locked drives I'd rather stay away from them. Samsung hard drives as well. Cheap doesn't equal reliable. I'd take the WD everytime.

It's all about luck. Even Google proved that failure rates are the same across all boards.
Seagates firmware problems are a thing of the past - almost 2 years ago now. They fscked up big time but I don't see any logical reason to not support their new unaffected drives.
Nor does expensive mean reliable.

Rofl, I have a friend who owns a PC shop and he slaps me just about every time I buy something online :P
Nom, just go there, I also went my details through to Esquire, never got a confirmation email but when I was there they said I did have an account, so just give it a try. Otherwise PM me, can make a plan. The more space you have the more HD movies I can copy from you next lan :P
