Raid 1 + SRT with WD greens?

post #1 of 5
Thread Starter 
I'm thinking about replacing my Raid1 2x2Tb WD RE4's with 2x4Tb WD Greens at some point in the future. The greens sound like a viable choice because of the reduced heat buildup and they're a lot cheaper than the RE4 or blacks.
The array will be accelerated with a 64GB SSD via SRT and the whole thing is running on the Intel controller of my Z77 board.

So, is using WD greens a bad idea for this?

Over here people suggested Raid 1 is probably fine with WD Greens but there was no SRT involved.
Yes I do regular backups. No, I prefer to not have to use them because I was too stingy for buying proper HDDs in the first place redface.gif

WD greens don't officially support RAID. If you have a run-of-the-mill read error on a green, it'll totally fail out of the RAID. The RE4 drives on the other hand are made for RAID and use the WD equivalent of TLER which prevents a simple read error from totally dropping the disk from the RAID.

If you're looking for a cooler alternative, look at WD Red drives. They still support RAID properly, are faster than Green drives, are a little hotter than greens, but are still much cooler and quieter than Blacks/RE4 drives in my experience. I almost never use Green drives anymore since the Reds came out - and as long as you avoid holiday shipping on bare drives (a long standing issue in IT) they work great.

Huh, the reds are just about 20€ more expensive than the greens and yet about 60€ cheaper than the blacks. Why oh why didn't I notice them earlier. I feel stupid now redface.gif
If they can survive in my ongoing build, being mounted like this I'm set.

so basically sandwiched but completely open aired

WD Reds would handle that much better than RE4's would. Reds are basically 5400rpm drives with some voodoo added that make them about as fast as a cheap 7200rpm drive.

voodoo? splendid! I'll add some SRT voodoo to speed them up even more biggrin.gif

Thanks for pointing me at them, +rep!
