Another Update: I transferred drives from the SYBA to the Yotta to test out the Yotta speeds with all 5 bays occupied by Seagate Exos drives. I am getting just slightly above 1000 MB/s when doing concurrent reads and writes to/from the drive pool! The theoretical max would be 1250 MB/s (10Gbps) on USB 3.1 so I am extremely happy with this.

Thanks 🙂 ! I just tested out a Yottamaster 5 bay FS5C3 with 2x Seagate Exos X18 18TB drives (pulled 2 drives out of the Syba enclosure to test out). Write speeds achieved slightly above 500 MB/s which is excellent, as each individual drive I tend to get about 270 MB/s per CrystalDiskMark benchmarks. I tested out read speeds by copying multiple files to this new drive pool and then reading off it with 2 separate windows read operations (basically, pull files off the drive pool in 2 distinct copies going on simultaneously. 534 MB/s maximum read speed achieved with 2 drives! Mostly oscillating between 510-534MB/s! SMART data can also be read from this enclosure. I think the Yottamaster is a winner here 😄 I think I will slowly repurpose the SYBA for cheaper / slower drives I may acquire or for some of the parity drives for snap raid. I will use the Yottamaster for my data drives for the speed boost. Anyways I hope all this info helps someone else trying to figure out what DAS (disk attached storage) enclosure they might want to use with Windows 11 Pro / Stablebit DrivePool / snapRAID. Now to figure out how to get WSL (Windows Subsystem for Linux) up and running and hopefully be able to use badblocks to thoroughly stress test the whole system 😅

That makes sense, so it could be an issue with the hdd enclosure -- I am using a Syba 8 bay hdd enclosure SY-ENC50119 (https://www.sybausa.com/index.php?route=product/product&product_id=1001) The specs say it has a "ASMedia ASM1074L and ASM1153E Chipset". I tested going from an external USB-C nvme SSD to the internal SSD and I get about 750 MB/s. The Syba DAS is connected via usb 3.0 --> to a usb type a 5Gbps port on the same computer. Since Syba DAS --> usb type a port on pc gets 450 MB/s write speed, I assume this means that the pc usb type a port & controller is probably fine. So then it must be the Syba DAS? Maybe the ASMedia ASM1074L and ASM1153E chipset has faster write speed than read speed, or only allows parallel drive access on writes but not reads? Seems weird, but is that the most likely problem here? I have ordered a different multi hdd enclosure with different chipset to test this out, but will be a few weeks before it gets here.

Hi, new to drivepool, I recently setup an 8 bay DAS that is usb 3.0 (5Gbps) and I am using 5x 18TB Seagate Exos currently. I tested out writing multiple files to my Pool Drive so that windows would have concurrent write streams going. I was able to max out at 450 MB/s which I was quite happy with. However when reading multiple files from the drive pool, I only seem to get 250-270MB/s which is the read speed of 1 drive. I would expect if I read file A from drive A and file B from drive B that I should cap out around ~450-500 MB/s just like I did with the write speed test. To make sure, I also tested going into drive 1 and drive 2 directly via the hidden PoolPart folder to directly pull File A and File B off 2 different drives at the same time. Windows shows 2 read operations going simultaneously and ... my speed caps out at 250-270 MB/s no matter how many different drives I read off of. I am writing to an SN850X NVME SSD which has a write speed limit around 5000 MB/s (tested in CrystalDiskMark). Any idea what I may be doing wrong? Initially I was only getting 50 MB/s from reading from the drive pool drive and realized smart scanner was trying to scan at the same time, reducing performance. After pausing smart scanner, I am in the scenario described above, where no matter how many different drives I try to read from that are in the drive pool, I can only read as fast as 250-270 MB/s. My drive pool has bypass file system filters, read striping, and real time duplication enabled in performance setings. However I am not using file or folder duplication at all at the moment (I plan to use snap raid once I feel comfortable with drive pool). Any help appreciated, thanks!

I hope that the developers add an option for us to set the polling interval. I prefer to keep the disks spinning, and the ability to prevent disk sleep is a feature and not a bug to me 🙂

Hi, I have browsed various threads regarding SMART data not being reported and tried various fixes to no avail. I'm hoping someone from StableBit might be able to help out. System: Windows 11 Pro Problem: Samsung T7 Shield Portable SSD connected via USB-C to a Minisforum NPB5. StableBit Scanner says "The on-disk S.M.A.R.T. check is not accessible" I have tried the stable version of StableBit Scanner v2.6.4.3981 and also I am currently running the beta of StableBit Scanner v2.6.5.3998 I tried the NoWMI and Unsafe DirectIO options & exit StableBit Scanner & stop/start the StableBit Scanner service in Services then relaunch StableBit Scanner to retest. I notice in StableBit Scanner that the Samsung T7 shows up as "Samsung PSSD T7 Shield SCSI Disk Device" I wonder if somehow it is being misidentified as a SCSI drive? CrystalDiskInfo displays the S.M.A.R.T. data for the Samsung T7 Shield perfectly fine.
