I built a new server this time last year. My board does 6 channel RAM so I bought 6x32GB ECC DDR5. $160 a stick at the time. Just for grins I looked up the same product number at the same supplier I originally bought from. $1300 apiece. One of the VMs running on that server is TrueNAS, with 4 20TB WD Red Pros. God help me if I have to replace a drive.
Best Buy is actively selling 2x8gb sticks of DDR4 3200 for $80 a stick. I was floored. Ten bucks a gig, $160 for the pack.
We're fucking doomed.
