i ended up going 12g myself after watching a friend **** with a pile of netapp and emc stuff for far too long.
well, 12g for the ssds, and a bunch of hgst 7k6000 for bulk.
i'm rambling tonight, but the single best storage purchase i've ever made was the hp lto-6 tape drive. around 2 months back, i had a couple people over for some casual gaming, and one of them had some version of phoebos ransomware, and that managed to nail most of my network through a rdp vulnerability that wasn't patched by ms until after the piece of shit exploited it.
i emailed the ransom address out of curiosity, and the jerk wanted $5000. i sent him a picture of a stack of tapes and my middle finger.
after wiping everything and restoring from tape, i lost 3 days of labor and almost 20 hours of data.
i hear a lot of others aren't so lucky.
offline backups are important, folks, especially with the nasty crap going around. if you want nightmares, take a look at how phoebos and adame hop from computer to computer, and where they scrape your passwords from.
also pretty interesting is that they open and rename as many files as they can simultaneously, and encrypt the first 2mb and some parts of the tail. they don't touch any system files, so nothing starts randomly crashing... you just get some odd cpu and disc (and network) spikes if you happen to be watching.
