January 15, 20224 yr 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, 20224 yr by Doublemyst

January 15, 20224 yr Community Expert 870 QVO is TLC and will be pretty slow once the SLC cache is filed up. IIRC about 80MB/s max.

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?

January 15, 20224 yr 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)
