trurl Posted September 29, 2020 Share Posted September 29, 2020 USB is not a reliable permanent connection which is required for parity array or cache pool. Usually you power drives from the same power supply as the motherboard. You might want more RAM if you want to try docker or VM. Quote Link to comment
Hari.B Posted September 29, 2020 Author Share Posted September 29, 2020 i am coming from WD my cloud nas .. i do not need more features. can i use UNraid like wd my cloud nas .. or do i need to put more efforts to maintain unraid ? 4gb ram good enough for this build ? i'm not interested in docker or vm Quote Link to comment

trurl Posted September 29, 2020 Share Posted September 29, 2020 Not enough information in that Amazon listing to decide whether to recommend or not. You could try it. Quote Link to comment
JonathanM Posted September 29, 2020 Share Posted September 29, 2020 There is a very high chance that controller is marvell chipset, so not recommended. I don't know of any 4 port controllers that will work well. Your options are asmedia based 2 port, or JMB585 based 5 port cards, or LSI based 8 port cards. There are some asmedia 4 port cards, but they use port multipliers, so also not recommended. This should work. https://www.amazon.in/CREST-Internal-Non-Raid-Controller-Bracket/dp/B07ST9CPND/ref=sr_1_2?dchild=1&keywords=JMB585&qid=1601386545&sr=8-2 1 Quote Link to comment

Hari.B Posted September 30, 2020 Author Share Posted September 30, 2020 (edited) ok, i would like to limit my requirement to 24TB (16tb or above) can i use on board 4sata ports and expect 100MBPS speed with 4gb ram ? Edited September 30, 2020 by Hari.B 16tb or above Quote Link to comment
trurl Posted September 30, 2020 Share Posted September 30, 2020 Each disk is independent so read will be at the speed of the disk containing the file. Write speed somewhat slower due to parity updates. Nothing about this changes regardless of how much storage you have or how much RAM. Basic NAS functionality should be fine with only 4GB RAM.

Hari.B Posted October 1, 2020 Author Share Posted October 1, 2020 (edited) 4x6TB = 24TB with 6tb parity .. how much write speed i can expect over FTP .. gigabit network connection Edited October 1, 2020 by Hari.B Quote Link to comment
