Md_write limit was removed from V6, don’t know if it makes a difference in speed but I change it directly in the flash/config/disk.cfg

Confirmed, no longer appears on my server that doesn't support blake2

I don’t know if you have plans to add more Seagates to the SASLP, but so you’re not surprised, expect parity check to slow down considerably with each additional disk you add past the 3 you have now.

Mine make the same click sound, I don’t like it, but from a google search it appears to be normal for these disks.

What OS is giving you that speed graph during the copy? Is that win10? Windows Server 2012 R2, but both Win 8 and 10 have the same graph.

I already posted on other thread but since this is the official one and for anyone interested in these disks I’ve found them to be some of the fastest I’ve used for parity check/sync speeds. This is from my latest server, still has one 3TB Toshiba 7200rpm, with all 8TB Seagates it would be slightly faster. Subject: Notice [TOWER7] - Parity sync: finished (0 errors) Description: Duration: 15 hours, 47 minutes, 30 seconds. Average speed: 140.7 MB/sec Subject: Notice [TOWER7] - Parity check finished (0 errors) Description: Duration: 15 hours, 53 minutes, 3 seconds. Average speed: 139.9 MB/sec Parity check is slightly slower because as I discovered with these drives the HP N54L has ~750MB/s max usable bandwidth on the onboard sata ports, parity sync was faster because only 3 of the 4 drives were reading, it appears the A-Link is full duplex. As for normal usage write speed, I’ve found it to be between 45 and 60MB/s for large files, and as expect slower than normal drives for smaller files, see image 2, as these are a very small percentage of my files I’m very happy with the performance.

That’s a very cool unraid server! I believe the CPU is soldered on the board, so not user replaceable. Be interested to know how the parity check speeds holds up as you add more disks, I believe that those CPUs have a single gen 2 PCIe 4x interface, although even if used by the 10 drives should provide ~160MB/s for each, which is not bad.

OK, thanks for the explanation.

Just checked and my HP N54L servers (with AMD CPU) also can't do blake2, I was using the default md5 because I hadn't notice this from your notes on the 1st post: Since md5 checksums can still be checked by corz what's the disadvantage of using it instead of blake2?

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! Adaptec doesn’t release every build, the last 2 on the site are: 6.0-0 Build 2507 6.0-0 Build 2329 You need build 2507 for >2TB support

Played a little with the new par2 creation, working great, many thanks! I know this is a very early version but is it possible to save the settings like recursive and redundancy %?

So start the array with the disk to be precleared so it builds "disk.cfg", stop the array, remove the drive from array, build "new config", then preclear_disk.sh should work? I just tried it to make sure and in fact you only need to do a new config, it creates the disk.cfg

Disk.cfg needs to exist, you can create a one disk array on the test server and then do a new config so the disk becomes available to preclear, or copy the disk.cfg from you other server.

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.

I never saw those results on my servers. On which controllers do you see these results? Onboard SATA ports? 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. 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.

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.

Although the 1430SA uses a Marvell chipset it does not use the same MVSAS driver as the SASLP and SAS2LP, I believe the increase in performance on your older system using the tweak was more from lower CPU utilization and less from any benefit to the 1430. The 1430SA has been a very consistent performer since unraid V5 and always delivers more than 200MB/s per disk, which is consistent with its max theoretical bandwidth of 1000MB/s. Different hardware and tunable settings can make a small difference but doubt that anyone with a Intel socket 1155 or above CPU will see any gains from the changes as the card is performing at maximum speed as is.

I recommend the adaptec 1430SA, relatively cheap on ebay and works very well with Unraid, just make sure it’s using latest firmware for > 2tb support.

Just to report that this worked perfectly for me to consolidate my TV series by season on the same disk, it took about 48 hours to complete, can’t even imagine how long it would take by hand. Thanks again.

That cable will work, have the exact same one, although if that price is in euros I think it’s somewhat high.

+1 I’ve also been using corz, very happy to be able to create/verify checksums without using a windows pc. Many thanks!

Is there a H320 or is this a typo? Before flashing the LSI (Pxx) firmware you have to flash the DELL IT firmware! Did you do this successfully? H320 was a typo - I corrected it. Yes, I flash the Dell It firmware first and I can do it successfully - I will attach flashlog for this job and pictures for what it looks like after Dell It flash. My sas address is 590b11xxx - do I perhaps have to change it to a Lsi address ? Have you tried the simpler procedure posted by opentoe? Worked great for me.

Many thanks to Freddie for these scripts, I didn’t plan my split levels as I should and I would spend days trying to do this by hand. Thanks as well to Benni-chan, I have over 1000 tv folders to consld8 and that helps a lot. Is it possible to output the test run for de line below to a text file? find "/mnt/user/TV" -mindepth 2 -maxdepth 2 -type d -print0 | xargs -0 -n 1 consld8 -t
