Well this 30TB is actually when for the first time Alliance started btcache, that is 11months ago, I guess by the time being they have upgraded the Network Storage when users started to flood. Its actually network storage hard drives attached to racks with greater transfer speeds. Something like this
These hard drives and their system are pretty much completely different, except for the hard-drive component itself. The system has some very cool and very configurable software involved which allows the sysadmin to finetune what/how much/for how long etc files should be stored. The hard drives in these pictures are simply so you can download stuff while your computer is off or your
laptop is not at home... I believe some of them have web interfaces so you could theoretically add a torrent to your download queue before leaving work and it would be done when you reached home so you can immediately put your feet up and plug it in to your Ethernet (or USB) ready
TV.
...both are cool, but for different reasons
🙂
With the increase in content I think now they have added more
NAS to their racks. And also for the first when user is downloading a file if at the same time other users also downloading the same movie or file then every users get increased download speeds.Its like i download some chunks and share at Lan speed in torrent to other Alliance user and he does the same vice versa. Everytime btcache is not needed. And if any user seeds a particular torrent who is on the same network then also user will get above 800KBps transfer rate on Utorrent even if it isn't in caching
I doubt they've needed to add more storage as yet - that would just be unnecessary expenditure on their part since they're not aiming to archive everything that every single user downloads, just the commonly accessed stuff. What I've often seen on my network is that when myself and someone else is downloading the same file at the same time, then his client will download some chunks from abroad, and mine will download some other chunks also from abroad, and then we'll share each others chunks at high speeds (being local peers) which results in 100% of filesize being downloaded (so say, a 1GB file means between 2 or more users, I've actually only used 1GB of my International bandwidth instead of having to have downloaded it twice or more).
