I work in a company right now we have a dell r640 server, with 8 x 2.5in front hot swappable storage, rear has 2 x USB 3.0 available. right now we have 8tb on our server, with 4 vm. Our company rarely use file server. However, sometimes they may transfer 5-10 gb of data over and read 5-10gb of data at a time.
our file server has 2tb only. We want to expand it. originally was thinking of getting a qnap 4 bay DAS and load 4x20tb sata hdd 7200rpm, with raid 5 support. However many review said go with JBOD and user software raid instead on Windows. However there are some concerns that 4 disks operating on 1 USB 3.0 cable may hinder performance.
So my options I am thinking is:
option 1)
QNAP TR-004 4 Bay USB Type-C Direct Attached Storage (DAS) with 4x20tb sata HDD.
plug it in to the back of the R640 Usb3.0 and use Windows software raid for 40tb of storage and set that storage for the filer server VM.
option 2)
put 1 low profile 2x usb typc C with pcie x4 connect to r640 pcie x16 gen 3 (https://www.amazon.com/FebSmart-10-15-x-Build-Self-Powered-Technology-FS-C2-Pro/dp/B089YN57TD/)
run 2x qnap TR-002-a-us 2 bay DAS with Type C. Dell r640 has 2 more pcie x16 gen 3 upgradable slots left.
load it with 4x20tb
Windows (server) raid to 5
total = 60tb with 1 disk for parity.
Option 3)
since there are still 4 more ports left open on the server, I load it up with 4x3.84 (https://www.amazon.com/3-84TB-PowerEdge-Servers-Enterprise-Drive/dp/B08B34H7FR/), raid 0 to get 15tb. Unfornately it's a smaller storage but this might be the best performance for transfer speed
I don't want people start complaining transfer speed is heck of a lot slower. Will Option 1 be too slow? will option 1 and option 2 pretty much have no diifference in performance?
