Hi Bob,

Thanks for the elaborate reply. During my research I bumped into your name frequently with replies to the communities.

I guess it’s a bit of a challenge indeed with 30 kids.

I had already set my eye on Synology, but after validating your input on the website I noticed that the benchmark nrs from Synology where based on SSD instead of HDD.

So the RS3621RPxs with 12 disks does 4718MB/s (with SSD’s) in RAID 5 so with HDD’s with a single transfer speed pf 150MB/s I estimate a speed of around 1188MB/s for 12 HDD’s in Raid 5.

But you are right, 16 disks is the bare minimum and with HDD’s I expect a throughput of 1585MB/s with this RS4021xs+.

I’m also rethinking my strategie concerning the gigabit connection per workstation.

Thanks for the generous valuable insights, very well appreciated

Best regards,

Michel
