    SSD Optimizer problem

    Welcome to the forum. As to stealing this topic.... on the top of this thread it states that the issue was solved by @Christopher (Drashna) way back in 2016. Given that DrivePool has been updated many times since then, if you have a similar issue as this old thread, then it might be better to start a new thread with your concerns. There was just another recent thread on the SSD Optimizer. You might also find that discussion helpful. When I was first setting up my SSD cache, I noticed that sometimes it would not flush properly until I rebooted the computer. After making changes

    Removing a nested pool

    For anybody who comes across this thread in the future with a similar issue: I wasn't able to ultimately figure out how this occurred but I decided to remove the E:\ pool from the D:\ pool using the default removal settings and that removed the extra drive letter. A SnapRAID scan of all the constituent drives that comprise my E: pool didn't find any unexpected changes, so it appears to have been a safe operation given limited testing.

  3. The SSD write cache did increase speed on my system, but it depends on my file transfer scenario. If I am transferring files directly from my server's drive into DrivePool on that same server, I see my maximum speed of the SSD (about 480 MB/s). If I am transferring files over my home network ethernet (about 30 MB/s), or wifi (? MB/s), or from an attached USB HDD (about 80 MB/s), then even my DrivePool archive HDDs are fast enough to keep up with the transfer. I have set aside 100 GB of my 228 GB SSD as my DrivePool write cache and also use that as a cache for my working temp folders. In

  4. DrivePool has a feature called Read Striping, which you can turn on. If the folder is duplicated, DrivePool will read from both drives and that can speed up the read task. If you expand the performance tab, you can see both drives that DrivePool is reading from and the speed at which it is reading. You can almost double the read speed in some transfers. What I see on my system is that DrivePool will read from both my SSD and an archive HDD at the same time, but since the SSD is just so much faster, most of the read data comes from the SSD. I don't know if DrivePool is specifically prog

  5. Spider99, Thank you! I found a few explanations and how to "shade tree mechanic" fix it, but this appears to be the least troublesome and easiest way out. You are a hero! When building systems at work cooking up a Nimble Storage Array with 1PB when it's not my money is up my alley. But building on the cheap at home with garage sale parts required more thought. Like playing chess it 4D. It just blows the mind. Now off to find some chassis to house the 3.5" SATA drives as 16 are 2.5" and work flawlessly in the MSA70. Maybe I can get out of the dog house once all of the h

    S.M.A.R.T. - 78.4%

    After a bit of research, I've discovered that even though the maximum value of an attribute is 255, manufacturers choose a maximum value that suits them (usually a nice round number). In WD's case, they have chosen 200 (200 / 255 = 78.4%). I have an HGST drive that seems to be using 100 instead which results in 39.2%.

  7. The auto refresh of Windows File Explorer has been a long standing issue with Windows. There are a number of fixes for this issue posted on the internet, but every version of Windows 10 seems to have a different solution. I personally just live with inconvenience because the next Windows update could "un-fix" the problem you thought you had solved. I don't have enough time in my day to manually apply "fixes" to Windows that might be wiped out next week on an update. So, if I need to refresh File Explorer, I just hit F5 and it will refresh. I also use a third party File Manager and it has

  8. Yes. But YMMV. Mostly, having the cache on a different drive means that you're separating out the I/O load, which can definitely improve performance. Though, this depends on the SSDs you're using. Things like AHCI vs NVMe, and the IOPS rating of the drive make more of a difference.

  9. I'd take a wild stab and say probably negligible difference so long as windows is idle and behaving; checking task manager, my fileserver's boot SSD is currently averaging ~1% active time, ~450 KB/s transfer rate, ~1ms response time and <0.01 queue length over 60 seconds at idle, and it's a rather old SATA SSD. I think you're much more likely to run into other bottlenecks first. But YMMV as it depends how many simultaneous streams are you planning for, what other background programs you have running, etc. You could test it? Open task manager / resource monitor, set to show the drive's

  10. Sorry, I haven't used CloudDrive nearly enough to be able to tell you whether your plan is actually sound (I use DrivePool and Scanner a lot more) though that may change in the near-ish future. "Drive Usage set to B only having duplicate files." - Have you tested that this works with a pair of local pools? If so, it should also work with a local+cloud pool pairing. "Is read striping needed for users of Pool C to always prioritize Pool A resources first?" - According to the manual the answer is no; regardless of whether Read Striping is checked it will not stripe reads between local a

  11. Well, this is embarrassing. Finally realized I was logged into the wrong gmail email account for the Google Drives *slaps head*. Wanted to delete this post but can't seem to find the delete option, but maybe its best it stays up so my error will help someone else whos brain was running on autopilot and signed in with the wrong gmail email hah.

  12. Yea the goal is to not need to pull a 20TB recovery when you could have just done a 10TB recovery it would literally take twice as long. Also you have a higher probability of failure. In my case: A+B = Duplication Pool 1 C+D = Duplication Pool 2 E+F = Duplication Pool 3 Duplication Pool 1+2+3 = Pool of Pools In the above example you can sustain more than 2 drive failures before you lose data depending on what drives fail. In the event of a failure where data loss occurred you will need to restore 1 drives worth of data. Next example: A+B+C+D+E+F = On

  14. Hi Newbie! ;D, DP needs very little, I had it running on an Intel Celeron G530 and could stream 1080p to at least one device. So a cheap build with, say, a Ryzen 3 3200G, 8GB of RAM, a decent 350W PSU and W10 would work like a charm as a file/stream server. The things you'd probably look for are SATA connectors (cheap boards often have only 4). Although you could get a cheap SAS card (IBM 1015 or somesuch, used.) which would provide plenty of expandability. The other thing is the network connection. 1Gb Ethernet, I think, should be "enough for anybody". It is a bit of a bad time as C
