Wadzwigidy Posted July 9, 2022 Share Posted July 9, 2022 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 Quote Link to comment

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.

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. Quote Link to comment
Wadzwigidy Posted July 10, 2022 Author Share Posted July 10, 2022 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 Quote Link to comment

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, 2022 by Vr2Io Quote Link to comment
