The WD Blacks are greatly overpriced and the Greens offer nothing significant over a Seagate that is 40% faster. WD Reds have no better failure rate than consumer drives in Home Server use. I would suspect the Seagate NAS drives are the same.

Right now I am adding 3TB Toshiba drives in my server. Once the 4-6TB drives have been used long enough to get a reputation I will re-investigate then.
I do get a little nuts with the HDD reliability thing. To me it's a commodity, something you need, use, and throw out. I've never seen any evidence that supports anything other than crap luck matters the most with reliability, and generally speaking even crappy hard drives are reliable. So the real small differences between one and another on a big scale, don't even realistically transfer down to the end user. But saving $20+ a unit when you need to buy many- Heck yeah. That is noticed and felt and appreciated. The cool thing- when I do replace a drive it's usually with a cheaper one, or bigger one anyways because the tech advances pretty quick. So that cash I saved the first round, goes even farther in the second round.

That's just how I roll. I would change my ways if I got burned really bad, but so far it seems to work. I buy and own just about every brand of HDD too. Price mostly dictates what I buy.

Can you elaborate? Do you use FlexRAID? I'm still deciding on my final product for my server and so far software configuration is pretty confusing.

Correct me if I'm wrong but "pooling" doesn't remove the individual drives from "This PC" under "devices and drives" it just creates another drive under "devices and drives" where all the pooled drives are in one virtual drive?

This is so much different than hardware RAID and thus confusing. I would like a product that replicates hardware RAID but isn't hardware RAID... I know that is a lot to ask for. I just don't want to waist all my time managing the media would just prefer to swap out a dead drive every now and then.

Pooling in FLEXRAID F does indeed remove the drives. They disappear and only the pool shows up after you install and configure flexriad-f.

You can access the individual drives via the control panel, or navigate or inspect what is on specific drives. You can also remove a drive from the pool and make it independent again. But the drives are otherwise removed from "windows" if that is what you are thinking.

Finally got my IBM M1015 flashed and installed last night using Mfusick's instructions on page 140. Only thing I did different was to get the latest LSI 2118it.bin (P20) from LSI and replaced the one that came prepackaged which is a couple years old. I was unable to flash it with my AsRock Z87 Extreme4 so had to go to a friends house and use one of his older, non-uefi PC's to flash the card. Works great and I really like how the mini-SAS breakout cables cleaned up my bay!

Once I get a little more time I'll play around with fRaids Validate and Verify feature to see if I can get my problems sorted out. If not, SnapRaid here I come!

If I migrate to SnapRaid, is there any difference in overhead or function between FlexRaid or Drivepool? I already own fRaid so I can use that just for drive pooling. If there would be an advantage to DrivePool, I don't mind purchasing it.

Thanks, habe
