marcusone Posted March 3, 2011 Share Posted March 3, 2011 Anyone have benchmarks for what hey see as direct write performance when using the 1.5TB or 2TB EARS drives as parity? I currently get ~30MB/s over gigabit direct write to my unraid box, so very happy, but find myself wanting to expand and keep total drive count low (lower power use) and since the 1.5 and 2TB drives price/gb is getting so low I want to consider them. Sorry if the answer is in the forum; I promise I did some searching first Just don't have tons of time to keep digging through all the great information here. Thank you! Quote Link to comment
rich.bingham Posted March 3, 2011 Share Posted March 3, 2011 I'm using a WD20EARS for parity (also in the array) and I consistently see ~30MB/s write speed over a gigabit connection. Quote Link to comment
marcusone Posted March 6, 2011 Author Share Posted March 6, 2011 Well... speed dropped in my system (WD20EARS drive on motherboard controller where the black drive was) and now direct writes to raid are 20-25MB (so a 5-10 MB/s drop , oh well). But using my black drive as a cache/backup "warm" drive lets me move files to the server at 70MB/s, just not protected until the mover goes, but for the most part its ok. Quote Link to comment
marcusone Posted March 9, 2011 Author Share Posted March 9, 2011 Corrected the speed problem... formated the drive "unaligned" without jumpers. So re-formated with 4k-aligned and now performs just as good as the Black (well, at least right now where no drives go past 1TB... I suspect a bit of a drop at the "back" of the drive).
