    Music NAS storage

    What capacity drives do you currently have? Is upgrading the current drives feasible?

    Second hard drive

    IDE (PATA) ports can take two hard disks per port, you'd need a suitable cable and make sure the drives are jumpered appropriately as master/slave (or cable select). There also some LBA addressing limits you may need to be aware of, but I believe that chipset is old enough and the drive is small enough (under the 137GB LBA limit) that you should be fine.

    SSD life expectancy

    TBW is the only manufacturer-specified standard metric usually published, is there another you're thinking of? P/E cycles specified by NAND type would be kind of generic. Actual drive lifetime, as several long-term tests have done, is a hell of a lot more testing intensive...?
  4. Performance lag relative to what exactly? What baseline are you using?

    2,5" 2TB HDD

    Western Digital Adds NVMe To WD Blue

    I'd be curious to see benchmarks, given the controller only has a limited amount of internal DRAM. Which should beat the heck out of actual DRAM-less designs, at least for typical desktop use...

    Safe materials to secure mSATA SSD

    Got any pictures of the said laptop and mSATA SSD mount? Usually you can find the screw and post to mount the SSD if the laptop was designed for it, but I'm unclear if your laptop was designed for it...?

    Need an Areca Expert For Odd Situation

    Have they changed things since the ARC-1680i days? We had a few failures and my notes definitely include what I described above when LeVeL2ReScUe did not work. I don't see any mention of SIGNAT in my notes at all, so I assume that is a significant change from the ARC-1680i-series to the ARC-1880i's... That said, glad it worked! (also, derp on me forgetting about LeVeL2ReScUe as a key step to do before what I described above...)

    New BackBlaze Stats

    That's what people have been saying since hard disks hit 1TB, then 2TB... That said we're long past the days where single parity in an array made sense. Long past.

    What settings for a 9271-8i without BBU

    Going from memory that sounds about right for mechanical hard disks, but I strongly advise that my memory on this is rusty...

    New BackBlaze Stats

    Everything 8TB and larger seems to be pretty reliable, at least we haven't found any Seagate 3TB ST3000DM001 or WD Green 1.5TB-like failure rates anywhere just yet. The 8TB stuff has at least been around long enough to make me pretty confident in that, the 12TB and larger not yet.

    External docking station problems

    Which exact make/model of hard disks are involved? Ditto for the docking station?

    8big raid - st3000dm001 barracuda compatible

    Either look for a refurb/used disk of the same model and firmware, or roll the dice with an equivalent 3TB drive of another model.

    Need an Areca Expert For Odd Situation

    Normal procedure if memory serves, you set all the failed disks to active, then delete and recreate the entire array without re-initializing.

    LACIE 8BIG - st3000dm001 DISK

    Intel Announced Optane Memory H10

    I wonder how this will shake out compared to other QLC drives, most of which seem to do a good-sized pseudo-SLC cache...
  19. Any more specs on the SSDs? They smell like typical SM2263 units but everywhere I've looked seems to be light on details.

    WD Black WD4005FZBX

    Well, with the logs you have, go back to Western Digital and send them the trace. Plot it out on a chart if it makes it more obvious. You should be able to get it up to level 3 support for a more detailed explanation.

    WD Black WD4005FZBX

    Is this with the drive in use as a data drive? Can you post a screenshot with a drive activity trace? Does this happen even if the drive is mounted out of a case and on a smooth firm ESD-safe surface? Just trying to eliminate all the other variables here, because this sounds like defective behavior to me. We use craptons of drives here and would reject any lot with that defect.
  22. "by an data cleaning app" Impossible to say without knowing the nature of the application. If it just does a simple delete (i.e. Windows or Mac moving files to the recycle bin) then you should be able to use standard data recovery utilities such as TestDesk to attempt recovery. If this "data cleaning app" actually securely erases files then you're probably SOL.

    9460 Broadcom VS Areca 1880ix

    Out of curiosity, which make/model of disk in each array?
  24. I assume the TV will handle a 4-bay NAS just fine? I've run into some limited USB device class implementations before where it handed a single-drive device just fine but then didn't know what to do with an unexpected device class. Regardless, I'd guess something baseline like a Synology DS418j would be a decent place to start?

    9460 Broadcom VS Areca 1880ix

    Not sure what's in Linux, but HDTach, AS-SSD, CrystalDiskMark... some don't play well with RAID tho (i.e. they're unusually affected by caching or whatnot). Maybe Brian or someone else would have better suggestions? (also thinking iperf, but that's usually for network...)
