July 21, 201411 yr I'll update the original post this week with photos, stats etc. Any questions? Any problems so far? Cooling ok? I've been running my side fans @ 1000rpms with the filter on. During high load drives are 40-45C. I may up it one more notch next time I reboot. They are around 30C @ idle.
July 21, 201411 yr That's definitely higher than I'd like to see ... what drive models are you using? ... and what's the ambient temp where your server is?
July 22, 201411 yr That's definitely higher than I'd like to see ... what drive models are you using? ... and what's the ambient temp where your server is? I agree. I'm just trying to find that sweet spot that I can keep the dust filter on. I'm using all green drives. House is 72-74F but server is in a closet that's open about mid level on a clear open shelf in the bedroom. So the ambient temp is probably a little higher. When I reboot again I'm gonna up them to 1100 or 1200 rpms. I'm not too concerned. It's just during parity checks/syncs. If all else fails I may modify the filter or just remove it.
July 22, 201411 yr Low 40's during parity checks and rebuilds isn't a big deal, as long as it's never that high during normal operation. Sounds like 1100 or 1200 rpm will do the trick.
July 31, 201411 yr Temps are currently between 30c - 38c That range is fine ... sounds like you've got the fans set just right now
August 4, 201411 yr Author That is great news on a side note I've cleaned up my original post and added some updates. I will post photos in a day or two
August 7, 201411 yr I'm a fan of the WD Reds, although both those and the Seagate NAS drives are excellent choices. Personally, if I was expanding to a larger parity, I'd spring for the new 6TB Reds ... but that may be more than you want to spend. The difference in cost/TB is nominal (about $5/TB at current prices), but of course the parity drive doesn't add any storage, so it's "sunk cost" that's $100 or so more than a 4TB unit.
August 8, 201411 yr I don't think I can get 6tb reds in the UK yet? http://www.scan.co.uk/products/6tb-western-digital-wd60efrx-wd-red-35-nas-hdd-sata-iii-6gb-s-intellipower-64mb-cache-ncq-oem-with-n
August 8, 201411 yr Author I won't touch Seagate with a barge pole. I've had to many failures!! Are these better than the hsgt drives? Sent from my Nexus 7 using Tapatalk
August 8, 201411 yr That's a WD drive -- not a Seagate. Probably not better than the HGST helium-filled drives; but the Reds are excellent drives and are half the cost of the helium units
August 8, 201411 yr Agree ... there are few independent lab-based test results available. Given a choice, I'd take the HGST helium-filled units; but NOT at double the price. The WD Reds perform quite well; and will definitely be the next drives I buy when I expand my UnRAID server (or build a new one).
August 10, 201411 yr Author Currently £400 ouch. Are there any guides on installing and setting up rsync and a UPS? Does anyone know how to automate sports?
August 15, 201411 yr Author 6TB Reds are currently priced just over £200. Hopefully by Christmas both drives will be half price
August 15, 201411 yr 6TB Reds are currently priced just over £200. Hopefully by Christmas both drives will be half price I think "half price" is overly optimistic ... but I DO think you'll see them ~ 20% or so less expensive by then.
August 15, 201411 yr Author I can hope! Ha. Which drive would get if money was no option? HSGT or WD Red?
August 15, 201411 yr I can hope! Ha. Which drive would get if money was no option? HSGT or WD Red? I presume you're asking about the HGST helium-filled drive vs. the WD Red. I'd likely still go with the Reds, since they have notably higher areal density. The 6TB HGST drive uses 7 860GB platters, compared to the 5 1.2TB platters of the Reds.
September 4, 201411 yr did you have to use an aftermarket Heatsink/Fan combo for this setup? Every setup i've seen is using a AiO board or an aftermarket HSF.
October 12, 201411 yr Author I need to upgrade my hard drives this week. Would you go for WD or HSGT 4TB or? I will be ordering by Wednesday
October 12, 201411 yr I need to upgrade my hard drives this week. Would you go for WD or HSGT 4TB or? I will be ordering by Wednesday Either the WD Reds or the HGST Coolspin drives are fine choices. FWIW, the HGST drives got higher reliability marks in the latest Backblaze report, so you may want to give them a try. They're available at a very nice price right now: http://www.bhphotovideo.com/c/product/835055-REG/Hitachi_0S03359_4TB_Internal_Hard_Drive.html/prm/alsVwDtl
