    DrivePool + Primocache

    Good day Jaga. Arg, so IOZone produces complicated CSV files? Darn, it looked perfect, all the website said it does is call standard disk stuff, not trying to measure position on disk or bypass cache. Sandra also looked promising. It's so difficult to find a benchmark for disks that doesn't try to get the disk's raw performance. Well who knows, maybe it is 4 times faster with PrimoCache enabled! When I go to their forums (it's on the todo list) to ask some questions, I'll ask if they know of a benchmark we can use. Thanks!

    DrivePool + Primocache

    Hey! Thanks for discussing this. You have me interested. When I have time I will go to their forums/feedback and ask about a dynamic-size cache. They will probably tell me it cannot be done, lol, but if they did manage it for their RAMDisk then why not with the cache? Even with a fixed-size, it /could/ be good to have a smallish PrimoCache sitting underneath the Windows cache, especially with write-back (you are correct, Windows' write-cache sucks.) I see you can group disks and create separate caches, that's good - I probably would not want to cache my fast-enough SSD, but the DrivePool
  3. Good day. For what it's worth, I tried just now on my own pool and the folder datetime is updated correctly (Win7, single pool 3 drives). How are the files created? i.e. which software creates them? For my test I just did New->TextFile and that worked OK... Regards,
  4. No issues with Kaspersky and the pool on my machine...
  5. Good day. I'm not sure about this, but you /could/ disable the DrivePool service and reboot, THEN disconnect the USB drives, and finally restart the service. I say I'm not sure, because even when I disable the service and reboot, the pool's drive is still there in Windows (the CoveFS device stays enabled) so I'm not sure if that would free-up the locks or not; you could try it... Regards,

    DrivePool + Primocache

    Hi Jaga. Comparing speeds with PrimoCache and then without ANY cache is not very useful, especially if you tell CrystalDisk to use a tiny 500MB file. I replied because I wish you would post numbers that compare the Windows cache VS PrimoCache, as I have been interested in PrimoCache. I used to run PowerCache (I think it was called) on Amiga, and could set the number of sets and the number of lines for the cache for each disk, so I was able to optimize depending on what kind of data was on the disks, and it was quite efficient. It was, like FancyCache, a sector-based cache, and I think it

    DrivePool + Primocache

    Good day. I think CrystalDiskMark bypasses the Windows cache when it runs its tests, but cannot bypass PrimoCache. So while PrimoCache looks impressive, you should really compare with something that doesn't bypass the windows cache, if you want to know how much faster PrimoCache is compared to native caching... Regards,
  8. Good day. Of course, this is kinda the whole point. Do you have Excel? You can load a CSV from before the loss of a drive, and a CSV from after the loss, and compare them. There is this function in Excel called VLOOKUP. You load both files into the same workbook as sheets, add a column to one of them and VLOOKUP the file paths in this one to the paths in the other; whatever's missing is what you've lost. You could setup conditional highlighting to do the same thing (I think.) Once you got a list in Excel, you can sort then copy/paste in a text file. You can then automate the process of re
  9. Hi. If you just mount the missing pool now and again, and use copy/robocopy/syncToy/whatever to synchronize the 2 pools, then I don't see any issues. Just remember that you always have to reConnect ALL the drives from Pool 2, or the pool will be read-only. I wish someone else who'd tried that before would jump in; DrivePool is not supposed to have any issues with the scenario you describe, so that's what I'm saying, but it's always better if someone answers that has actually done it before (taking drives offline/online repeatedly.) I've done something similar, and DrivePool detected my pool ju
  10. That ticket is private, i.e. I cannot see the details. But I think 1 MB is a good chunk size; I'm not sure increasing it would make a difference (not knowing how read-stripping works, I cannot say.) So long as you remember you have a Nuts-n-Bolts to do on this, I'm good; we can discuss once it's published. Of course you could push and push and push for better performance, lol, but I'm okay waiting until someone @ StableBit decides now is the time to tackle this. Thanks again for being here! Regards,
  11. What's fantastic is that DrivePool supports them!
  12. Hi A Pool A Day Keeps The Doctor Away. There was a big discussion about this, see here: File Placement Based On Folder (towards the end I added a few replies on the problems I'd run into if I was to code this myself...) As for backup, just so you know, if 1 drive is missing from a pool, you can no longer write to that pool until you re-balance (i.e. remove the drive from the UI and see what happens.) So at least you'd have to make sure you always reconnect all the USB drives. Christopher can say for sure about what would happen when 2 pools are related by duplication and then 1 pool
  13. Hi Christopher. I agree that DrivePool cannot be as fast as a stripped array, but unless Alex explains where the difficulty lies (and it's quite possible there *is* a big difficulty,) I am for now convinced it can do better than 10% improvement reading the same file on 2 drives. I'm pretty sure we can cook-up a simple test program that sends a read for a MB off to drive 1 and then immediately sends a read for the next MB off to drive 2 (using ASync I/O so both reads go off and then the program sleeps,) and so on, and achieve respectable results. I don't know, maybe the driver cannot do AS
  14. Hi Christopher. Lol, you know what that means: my BitLocker_PoolPartUnlockDetect.Override setting had not been working since the get-go! I don't really hear the drives spin-up or down, so it's hard for me to see if they spin-down as they should, I'd have to leave the computer idle on purpose and I haven't really had time to test this. I /think/ they don't spin-down, but it could be something else than DrivePool, like the Intel RAID driver that's still running the drives (I had to disable spin-down in Windows when this was a Intel RAID otherwise the Intel driver was fighting the sleep and
  15. Hmmm, interesting issue, looks like the SSD-Optimizer is used even during balancing passes, which is kinda unexpected. Thanks for the tip that SnapRAID keeps growing (until you do a re-initialize or whatever the command is.) I plan to use a disk bigger than the biggest disk in my Pool for SnapRAID, but was not planning to try to minimize changes to files; maybe I should...
