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

I posted on page 72 on how to go through he flash process on a newer mobo with UEFI.

This thread has taken on some serious life of it's own.

Ok my BR#2 drive is indeed DOA. Won't show in my desktop hot swap either. So I do indeed have a busted Seapuppy. On the good news all my drives showed back up too. Looks like I am back on track- odd though how it was behaving.

It would be nice if both sets of instructions could be stickied in this forum area since the use of these boards is so common or, if Mfusick could edit the first page and link to both sets of instructions???? Page 70 is pretty far back from 148 and although I've followed this thread daily, I didn't remember that post. Bummer!

Sure I can edit the first post- just link me up or quote what you want me to add to it-

The only bad thing, is that my path was through trial and error, and I didn't make it through cleanly. On top of that, it's been over a year since I did the flash. I'm not sure what the 'clean' steps would be right now.

Maybe perhaps add a link to my post on Page 72 with something to reference UEFI boards.

Cool!

Your non-UEFI instructions are on page 140 and Wileys on page 72.

If you want to add it, here is the link to LSI's website where you can get the latest P20 firmware. http://www.lsi.com/products/host-bus...s-9211-8i.aspx. The current package is - "9211_8i_Package_P20_IR_IT_Firmware_BIOS_for_MSDOS _Windows". Also, all of the UEFI stuff is on there too.

I used your instructions from page 140 except replaced the 2118it.bin that came with the SAS2008 package (the firmware included in the SAS2008 link is P16, from 2012) with the latest 2118it.bin firmware (P20) from LSi's website (worked fine).

Should save people time from having to search how-to-flash instructions in the future.

Thanks,

No, this is exactly how FlexRAID works also. The difference is that SnapRAID does only parity (and fake read-only pools but that's another topic altogether), vs. FlexRAID that does both in one software package and has one configuration option that does both behind the scenes. But it's just an illusion, it's still vitally important that all users understand that pooling and parity are vastly different and wholly unrelated to each-other, regardless of whether you use FlexRAID, SnapRAID, disParity, DrivePool, whatever...

This is true only if you use Cruise Control mode. I always argue that Expert mode is the "correct" mode, and in that instance the configuration is far more similar to SnapRAID. It does not take over control of your drives, it does not change any hardware configurations, etc.

I highly recommend using only P19 or older. P20 has been known to cause multiple issues and is difficult to downgrade from. Maybe it'll be fixed if they do a P21.

I own both DrivePool and FlexRAID. I currently use FlexRAID for pooling but I have not yet even tested DrivePool. Both have free trial periods, so you can give them both a shot. I will say that FlexRAID pools have some issues with software that doesn't follow proper "etiquette" for opening and writing to files. FlexRAID is very strict in not allowing "proper" usage. I don't know if DrivePool is the same. For the time being, I'm sticking with FlexRAID pooling specifically for the virtual Recycle Bin. DrivePool is a much more "powerful" pooling solution aside from the lack of a virtual Recycle Bin, but I don't know that it's any faster.

Read your reply and I googled up issues with the P20 firmware and sure enough......Great!! Just my luck that I didn't know about this before I flashed mine with P20. I saw where others said they were able to downgrade back to P19 so I'll give it a go when I have time.

Thanks for the info.
