My 8TB Seagate failed a week ago and I was looking into new drives. The cheapest HDD was around 25 EUR per TB (for the 18TB ones) and the cheapest SSD were under 50 EUR per TB. No idea where this “7 times cheaper” comes, maybe from 2015.
I ended up buying a 4TB Crucial MX500 with 4TB for 208 EUR (barely enough for my data, but with some cleanup it will hold a year for sure).
Not only it’s faster, it’s smaller (fits in the NUC), it’s quieter and it consumes much less electricity. I don’t think I will ever buy an HDD ever again. Maybe for surveillance recording?
$200 for a refurbished 20TB drive on Newegg
The new ones were on sale for $270 so around $10-15 per TB. The best I can find is $40-50 per TB for SSD. Certainly not 7times more expensive but more like 3-5.
They ain’t called Seabricks for nothing. SSD will let you sleep at night.
Not that many 18TB SSDs available though. Might (and probably will) change in the future, but today, if you want massive amounts of storage, HDDs are your only reasonable solution (ignoring magnetic tape) unless you really require the read & write speeds of an SSD. Imagine Backblaze trying to replace their 46000 16TB HDDs with a few hundred thousand smaller SSDs in their datacenter.
You compared cheapest by cheapest, however items cost is more efficient with larger sizes
If you compare the best GB per $ sizes of both media types it is likely going to much more apart.
I compared cheapest per TB. The HDDs were most efficient at 18TB, the SSDs at 2 or 4 TB.
