December 14, 201411 yr I'm buying a drive to replace one I think is failing, ran 58 in a parity check and is getting noisier. I've posted about it in here before, most dont think I really need to and perhaps not. I just had one older drive fail though (not in my unRAID) and with this one hitting 58 during parity checks I just assume replace it before it's a problem. I dont buy drives too often and wont need to expand my array any time soon so I'd rather be stable . Anyway, here are the 3 options: Seagate Barracuda STBD3000100 - $105. I have two of them (slightly different serioa. no issues, but i'm reading about a lot of people complaining of issues a year in. The older version like i have had worse reviews, but still seeing comments in the reviews on this model, even though it has 4 eggs. TOSHIBA PH3300U-1I72 - $115 I hear this one is slower, but more reliable. I heard the HGST NAS drives were supposed to be the better without getting too crazy expensive. The 3TB are still $165 (considerable jump), but then i found NewEgg had the 4TB model for $169 (only $4 more than the 3TB). Seemingly a pretty good deal I considered making this my parity and using my current parity to replace the existing drive. Having said that, I dont see needing to expand the array any time soon, so not in great need to up the parity size. Anyway, just looking for thoughts out there, thanks in advance.
December 16, 201411 yr Author Any thoughts? Unless someone has information that the Seagate is really more reliable than the complaints would suggest, I can't sacrifice stability for speed so that pushes me to either the Toshiba, or the HGST. The HGST is about 45% more money for the same size drive and just happens to have a sale on the 4 TB. I dont need 4 TB but silly not to get it since it's only $5 more. I think the real question is, are the HGST drives that much better than Toshiba? Stability? Speed? Combination of both? http://www.newegg.com/Product/Product.aspx?Item=N82E16822145912 http://www.newegg.com/Product/Product.aspx?Item=N82E16822149396 http://www.newegg.com/Product/Product.aspx?Item=N82E16822148907
December 16, 201411 yr Toshiba drives started out with Hitachi technology as I have two 3TB drives that have Toshiba stamped on them that identify themselves as Hitachi drives. They have made changes to the firmware on subsequent purchases of the same Toshiba model that identify themselves as Toshiba and appear to have a faster access for me. However I think the quality of the drive has gone down some. The 3TB Toshiba DOAs appear to be a little greater count than the Hitachi and HGST drives I've got in 2,3 & 4TB drives. They (the Toshiba drives) are similar to the WD Red drives I own as far as DOAs are concerned. The Hitachi/HGST drives I've got have only had drives die due to age so far. I don't remember getting DOAs. But I also have been buying HGST drives from other online retailers that are NOT Newegg. All of the Toshiba and most of the WD Red drives were purchased from Newegg. So some of my DOAs could still be from bad packaging on them but the packaging from Newegg has improved a lot compared to a year or two ago.

December 16, 201411 yr Seagate Barracuda STBD3000100 - $105. I have two of them (slightly different serioa. no issues, but i'm reading about a lot of people complaining of issues a year in. The older version like i have had worse reviews, but still seeing comments in the reviews on this model, even though it has 4 eggs. I have a number of these drives, They are very fast and would do well in the parity position. They get about 190MB/s on the outer tracks. I heard the HGST NAS drives were supposed to be the better without getting too crazy expensive. The 3TB are still $165 (considerable jump), but then i found NewEgg had the 4TB model for $169 (only $4 more than the 3TB). Seemingly a pretty good deal I considered making this my parity and using my current parity to replace the existing drive. Having said that, I dont see needing to expand the array any time soon, so not in great need to up the parity size. I have this in another array in the parity position, It serves me well. The HGST drives have been very reliable in my arrays. The small price increase to 4TB is worth it for the 7200 RPM model as you will have room to expand later and the speed will be there. Average speed is from 140-175MB/s on the outer tracks. The HGST drive will run warmer as it has more platters, but it's designed as a NAS drive and it provides good throughput. I cannot comment on the Toshiba.
December 16, 201411 yr B&H tends to have pretty good prices on HGST. The other day I saw a 4TB Coolspin for $140.

December 27, 201411 yr I'm a little late to the party, but http://lime-technology.com/forum/index.php?topic=35576.0 is a good reference. It encouraged me to spend a couple more bucks for the HGST.
