If I recall correctly, the total storage requirements for the site were only around 8 TB a few years ago. It's probably not big enough to justify buying a tape drive.
 
Tape systems are not all that expensive, just a pain in the arse to manage.

It sounds to me as if Null was not monitoring his disks. That is a failure on his part.
null needs a dedicated computer janitor that isn't transgendered... who's still willing to work for free. an astronomically difficult task in the modern era
 
Tape has effectively ZERO random access performance and wears out extremely fast in use. It's only really usable in (and hyper-optimized for) the niche of third tier backups and long term archival where you write it once and hopefully don't touch it again until the data is safe to delete and you shred the tapes.
 
I don't know man, tape drives weren't all that impressive in my recollection.

What Seymour said. LTO drives are absolutely amazing at long term storage but complete ass at being used for random access and constant reading.
As a proud owner of an LTO drive, I can confirm.
It's true that starting with LTO-5 you can format tapes into LTFS filesystem, which makes the tape behave like a HDD (previously you had to use specialized software to write to and read from tape). And yes, data reading and writing speed is about the same as a HDD. But LTO is a linear storage format, so even if you have LTFS support, if you try to open up a file directly from tape, it will rewind for minutes searching for it before even loading it!
I remember trying to watch a movie from my tape backup (cuz lol enterprise-grade VCR). I had to wait over a minute for it to start playing.

Tapes are cheap, but disk drives? Nah. You can occasionally get a used LTO-5 drive for <$200 (and not in a dogshit condition), but you really have to get lucky for that to happen.
 
Why is @Null still using SSD / HD storage when he could upgrade to tape drives for backups.
I know the tapes themselves are cheap, but aren't the drive worth thousands(I think I've read around 10k somewhere)? Kiwi farms only has around 1500-3000 active user's from what i've seen, I can't imagine it makes enough to justify a purchase like that, when buying a few 4-8tb HHD's costs only a few hundred.

There's also a rather sneaky caveat where the tape requires a minimum R/W speed to function properly. If you run out the data buffer, the drive motor can actually outrun your data stream and will have to stop-rewind-restart to get back to where the buffer left off, which is not only horrible for performance but it also severely degrades the tape if it keeps happening. It's not like spinning rust where the drive just has to wait 10 msec for the next rotation or Flash storage where the controller has no problem even with really choppy data streams.

Seems like you could get around that issue if you had a big enough cache on the device, but I suppose that cache would sometimes have to be pretty big. Is this something that crops up with heavily compressed data streams? I saw a listing for an LTO tape once that advertized like 100 TB, as long as you compressed the data 5:1.
