first, run memtest86 (if you use x86 cpu)
check ram memory speed
my hp (ml350g5 very old: 2005) get 2500MB/s (~20 Gbits/s)
maybe ram is a bottleneck for 50gbits....
you will need a multi computer raid or stripe fileaccess operations
(database on one machine, s.o. on another...)
for hobby = SATA2 disks, 50USD disks of 1TB 50MB/s
the today state of art, in 'my world' is: http://www.ramsan.com/products/3
I doubt 20TB SLC which will survive huge abuse (writes) is low-cost
solution what OP wants to build himself..
or 20TB RAM omg..
