July 9, 20223 yr Is something wrong with my setup. I mean I know it's a Frankenstein and I know parity checks are slow but I think 8mb per sec means something is either setup wrong or not optimized very well. Would any be able to shine some light on why it's so slow and how to speed it up. Thanks in advance. wadzserver-diagnostics-20220708-2357.zip

I did have to plug it into one of the USB2.0 ports due to USB3.0 port availability. I have a slot adapter on the way to utilize the 3.0 header on my board, that should help. I'll update post with results of that. You think that is the only thing. I mean 8MB/s seems extremely slow. My parity check is 5% in and were looking at 2 days before it's finished.

That is one of key point, if 4 disks in that enclosure, then ~30MB ( USB 2.0) share for 4 disks, max ~8MB per disks.

Well I'll be, if I would have just done some simple math lol. Thank you for you help. Once I get this slot adapter things should be much better.
July 10, 20223 yr Author That did the trick. I added a usb 3 slot adapter and connected the 4 baby into it and the speeds are 20MB/s avg. I realized I have some SATAII drives in my array as well. Replacing those with SATAIII drives will increase speed as well. Thank you for your help @Vr2Io

SATAII or SATAIII shouldn't relate, it may relate some age disk got abnormal slow, you can use diskspeed plugin to check all disks performance, and there may be limited bandwidth at south bridge I/O also affect the speed. Longtime ago, I use USB enclosure ( also Jmicron solution ) best speed was 300MB/s ( USB 3.0 ) share for 5 disks, so ~60MB reach. Edited July 11, 20223 yr by Vr2Io
