opentoe Posted November 7, 2015 Share Posted November 7, 2015 Which mechanical drives get 200MB/sec in speeds? I'd love to find those. All the individual speed tests I've tried I always maxxed out of around 150MB/sec. Link to comment
garycase Posted November 7, 2015 Share Posted November 7, 2015 Which mechanical drives get 200MB/sec in speeds? I'd love to find those. All the individual speed tests I've tried I always maxxed out of around 150MB/sec. The 6TB WD Red Pro hits 214MB/s on the outer cylinders ... this drive has an areal density of 1.2TB/platter. Other 7200rpm drives with equivalent platter density should hit this as well. I suspect the 8TB Seagate SMR drives top 200 as well with their 1.33TB/platter density, even though they spin slower (I believe at 5900rpm). Link to comment

Is there a site out there that shows this information on drives? I have all 7200 RPM drives, a couple fairly new 4TB models and only see a max of around 150MB/sec. I would imagine that doing individual speed tests not saturating the controller I would see better speeds on a couple of the drives I have. Link to comment

I would imagine that doing individual speed tests not saturating the controller I would see better speeds on a couple of the drives I have. None of the 4TB drives have platter densities exceeding 1TB/platter, so they're not going to get reach the same speeds as the 1.2TB units. For example, the 7200rpm 4TB WD Red Pro specs show 171MB/s. The 7200rpm 6TB HGST units are also 1.2TB/platter, so they should do better than 200MB/s, but their 4TB units have 1TB platters, so they won't achieve those transfer rates. Link to comment
JorgeB Posted November 7, 2015 Share Posted November 7, 2015 Of the disks I currently have I’m very impressed with the 8TB Seagate, just hope they are reliable as Seagate is not usually my first choice. The 3TB Toshiba is also a good performer, both can do ~200MB/s in the outer cylinders. Link to comment

I get 30-40 MB/sec lower results on the whole line. What could be the bottleneck on my Main server? If there is any. Link to comment

Perhaps LSI SAS controllers, like your H310 and my M1015s, need some tuning and optimization too. Link to comment

Those results are disk dependent, especially because the disks are tested one at a time, any sata2 or above controller should be capable of 250MB/s+. Few disks on the market today can do 200MB/s+, these two are the exception from the ones I have, mostly WD green drives. Link to comment

I get 30-40 MB/sec lower results on the whole line. What could be the bottleneck on my Main server? If there is any. The controller isn't the issue -- as I noted earlier, you're only going to see speeds in the 200MB/s range with either 1TB/platter drives that are spinning at 7200rpm or with drives with higher areal densities. The two drives Johnnie posted the reports for are a 3TB Toshiba with 1TB platters and 7200rpm speed; and the Seagate 8TB SMR drive, which spins slower (5900rpm) but has a higher areal density of 1.33TB/platter. Note that NEITHER of these are rated at 200MB/s speeds (and in fact don't quite hit it) -- the Seagate specs show a max sustained rate of 190MB/s and the Toshiba shows 170MB/s ... but I'm not surprised the initial burst is close to 200MB/s (this likely includes transfers from the drive's buffer). If your drives have lower density and/or lower rpm, they won't get nearly as high. e.g. all of my newer drives are WD Reds, which tend to top out at ~ 150MB/s for the 3 & 4 TB versions (which have 1TB platters) or a bit over 170MB/s for the 5 & 6TB units (which have 1.2TB platters).

I have 3 TB and 4 TB 7200rpm Hitachis in my array. They are faster than WD Reds. Don't know it they have 1 TB platters. No, they don't. Probaly 5 platter disks, either 600 and 800 GB platters. I probably see a speed boost when I move to 6 or 8 TB disks. But seeing prices here in Netherlands, that will have to wait. Link to comment

garycase Posted November 8, 2015 Share Posted November 8, 2015 ... The disks are the only true bottleneck. That's true for the vast majority of folks who complain about disk speeds, parity check speeds, etc. I've seen several folks buy nice new 3-4TB WD Reds and not understand why their parity check speeds don't increase ... until it's pointed out that they still have some older much-lower-density drives in their system; and perhaps even mixed sizes, which result in multiple slow-downs as each different size drive limits the speed due to the much slower inner cylinder transfers. It's easy to get spoiled with 1TB/platter (or greater) drives -- but it can get a bit pricey to replace ALL of your drives with the higher density ones. Link to comment

After all you don't run a parity check on daily basis. And I won't see an improvement in parity check speeds until all slower drives are replaced by 1 and/or 1.2 TB platter drives. And then there will be even higher density drives and the speed race continues. As long as I get average speeds above 100 MB/s I am a happy camper. Link to comment

As long as I get average speeds above 100 MB/s I am a happy camper. Yep, it's a never-ending race to the top. I don't even average 100MB/s on my media server, which still has some old 500GB/platter EADS drives in it. My other two servers are all 1TB/platter (or higher) drives, so they do just fine ... but it'll be a while (if ever) before I replace the rest of the drives in my media server. As you noted, a parity check isn't done all that often -- and I always do it overnight so it really doesn't matter how long it takes Link to comment
JorgeB Posted November 9, 2015 Share Posted November 9, 2015 ...As long as I get average speeds above 100 MB/s I am a happy camper. Agree, 100MB/s is a good average speed and what I shoot for, I try to keep my parity checks under or just over 10 hours so I can run them overnight and they don't slow down the servers during the day. Also electricity here is half price during the night so that's another bonus. Link to comment
rcrh Posted November 11, 2015 Share Posted November 11, 2015 I'm thinking about buying this card. Can you tell me what the "latest" firmware is so I can confirm with a potential seller? Also, is the firmware flashable (ie, can I update it myself)? Latest bios is 2507, you can download it from the adaptec website and flash it. http://www.adaptec.com/en-us/downloads/bios_fw/bios_fw_ver/productid=aar-1430sa&dn=adaptec+serial+ata+ii+raid+1430sa.html Johnnie, My card just arrived and the bios is v6.0-0 B2322. Is the number you listed just the end of the version number? Otherwise mine is 2,501 versions out of date! Link to comment

As already noted, you need 2507. Just download it; create a bootable DOS USB flash drive; boot to it; and then run the update utility ... it will automatically update the card and you'll be ready to go. Link to comment

garycase Posted November 11, 2015 Share Posted November 11, 2015 Yes, that's correct. You can do it whenever it's convenient in that case. It's a VERY simple process and only takes a few seconds to do the update. Link to comment
garycase Posted November 11, 2015 Share Posted November 11, 2015 FYI, if you're not familiar with how to create a bootable USB Flash drive, just download Rufus ... it doesn't get any easier than that => you just run it and it will create a bootable flash drive for you; then you just copy the Adaptec firmware upgrade for v2507 to the flash drive ... and then you're ready to boot with that flash drive on your UnRAID server and do the update. http://www.majorgeeks.com/files/details/rufus.html Total time to download Rufus; download the Adaptec update; create a bootable flash drive; and do the update shouldn't be more than ~ 5 minutes [Maybe 10 if you're ultra cautious] Link to comment
