Good luck with reliability, let's talk in 10 years when you'll have no data on those ssd's and hdd working still great.\
HDD technology is most reliable, so i'll stick with it for my data magazine (i use 3TB hitachi hdd, very reliable) and Samsung 850pro 512GB SSD drive i've bought few months ago (before 512GB capacity i've used samsung 850 pro 256GB, and Crucial 120GB before the 256GB one).
Crucial ssd drive after a year was already showing signs of data reallocation because some of the cells were dead already and it was a pain in the ass to rely on it, so i've went for 256GB Samsung 850pro, and after that 512GB 850pro.
Anyway, my hitachi 3TB HDD is greeat for storing a lot of data, games these days use a lot of space, and since i own over 720 games just on my main steam account then i need a large space to fit it in. Even if i would be offered 3TB SSD for the same price of Hitachi 3TB HDD i'd go with Hitachi HDD (most reliable drives on the market) because i'd rather use the slower HDD and have my data safe there for decades, rather than worry that i'd loose my data on SSD...).
Maybe it's my bad luck, but i've had few pendrives and SSD's that died when i was using it, but HDD's cause less trouble for me in terms of data loss.
Btw, don't bother buying cheap Seagate, WD or Samsung (i guess samsung is not selling HDD's anymore). Hitachi and Toshiba HDD's are the best, also there are few good WD models but those are more expensive than most popular cheap models.
