I'm getting 2 3tb drives to do a raid 1 config. It will be used to store all my work data (which includes a lot of stock files for CAD and 3D modelling), plus anything I want to safekeep. Initially I was going to get 2 Seagate 7200rpm drives, but seeing that their failure rate is 26%, I've decided to go with WD green 3tb (5400rpm). Since I've never had a 7200rpm drive before, would I miss out on a lot of performance, considering that the drives are only for storage, no program?
Is there any other affordable 3tb 7200rpm drives beside WD black?
Lastly, for anyone who have used raid 1, is there an increase in read speed?
Thanks in advance for any help rendered :)

Right, thanks for the suggestion. I can't seem to find HGST drives in Singapore though. Any idea how much they cost for 3tb and where I can find them? If not, Toshiba drives seem decent, almost on par with WD in term of reliability, and quite cheap too.

TS, please do some checking... 3TB failure rate is much higher than 4TB or 2TB... consider carefully first.

Oh shoot. Thanks so much for the head up. I'll probably get the 4tb drives then.

Wd red 3tb

Green is just terrible

Red is 5400rpm too if I'm not wrong. And it's NAS. Just out of curiosity, is there much difference between regular drives and NAS drives?

I was also looking for 3TB initially some weeks back, then read the comments here and google.. end of the day i settled for Toshiba 4TB at < $200 :D .
Currently using Raid 0 and so far so good.

HGST drives are sold directly by Convergent on Lazada...

The astronomical 3TB drive failure rate was very much because of the high Seagate failure rates; if you go with HGST or Toshiba there shouldn't be anything to be concerned about.

NAS drives are allegedly optimized for 24/7 usage, opinions are mixed about the effectiveness. The main issue with the Greens is their excessive head-parking behavior to save power, which doesn't play well with RAID arrays. You can disable this via firmware, but it's a big hassle. I personally wouldn't touch WD Greens with a ten foot pole, and their other options are very poorly priced for what you get.

Can try video pro - http://list.qoo10.sg/item/HGST-HGST-DESKSTAR-NAS-DRIVE-3TB-7200RPM/428514653

Order directly from videopro's website or buy from their store at SLS; for some reason they charge more on qoo10. I only paid $169 per 3TB HGST drive. They're a little pricey, but I'm running 2x HGST and 2x Toshiba just to avoid putting too many eggs in the same basket.

You got data to show 5400rpm vs 7200rpm MTBF?

I did my research a long time ago. Not sure whether anything has changed. But personally, without that research, i would think slower drives has less vibration and more stable.

So where is your data to suport that claim?

WD Greens and Reds have statistically seen far more deaths than higher spindle Blues and Blacks.

They probably markup to accomodate promo coupons and such available on qoo10, for those who seek them out anyway.

Long time ago meaning years back and I can't bother to dig up. as mentioned, may not be valid anymore too. But i do recall it was refering to HDD in general. Lower versus higher rpm. In this case for WD, black is more costly and better quality. So not surprising the reverse is true.

Whatever it is, stay away from 3TB HDD. There is a reason why they are priced very aggressively too.

For me is either 2TB if on budget or 4TB if can spend more.

(HGST>>>WD>Toshiba(3.5 inch only)>>>>>>>Seagate)
