Doublemyst Posted January 15, 2022 Share Posted January 15, 2022 (edited) Hi, I have the issue, that my read / write speed is sort of slow. In order to test, if my setup "workspace on VM and my main computer will be my server" will work, I have created a new unraid instance. In this instance I only have 1 TB SSD drive. When I copy file inside Domains folder, the speed is pretty low. It is the same speed I have with my regular server and HDD disks with parity. Am I doing something wrong? What can be the reason for it? If it matter, my processor is AMD Ryzen 5 5600X 6-Core @ 3700 MHz. Edit: here a screenshot: Edited January 15, 2022 by Doublemyst Quote Link to comment
itimpi Posted January 15, 2022 Share Posted January 15, 2022 You are likely to get better informed feedback if you post your system's diagnostics zip file. Quote Link to comment
JorgeB Posted January 15, 2022 Share Posted January 15, 2022 870 QVO is TLC and will be pretty slow once the SLC cache is filed up. IIRC about 80MB/s max. 1 Quote Link to comment

IIRC about 80MB/s max. Ah, alright .. Just saw the 480 mb read/write, and assumed it will be the average Is there a SSD you would suggest, where this speeds will "maintain"? Or what should I look for? Edited January 15, 2022 by Doublemyst Quote Link to comment
Squid Posted January 15, 2022 Share Posted January 15, 2022 Also should be noted that trim is not supported for array devices. Whether or not this impacts your use case is unknown. If it does, then you assign that SSD as a cache pool and assign anything else (even a 16G flash drive) as a data drive (even though you'll never use it) 1 Quote Link to comment
