Any tips for handling large torrent?

Hi

For the moment I got a Dell computer with some external Hdd's, this is used for downloading and streaming. However I would like to have a simpler solution, something that can recover from a power outage without me doing anything.

A year ago I used a pogoplug V4 with debian for downloading and streaming to my ipod over ftp, it would also recover. However the amount of data is now bigger than the pogo can handle (to little ram). Ive got some raspberry pi's with that I think might replace the pogo.

The better solution could be to buy a good NAS, however I always find it hard to manage all the data over the network. I wonder what solutions other people use.

currently use https://www.readynas.com/?p=6140 with 9Tb RAIDX(netgears RAID implementation) setup with raspberrypi's/desktop machines connecting via NFS/samba clients...
rtorrent running on one mapped to a NFS mount, running btsync (syncs wiht my phone, so torrent d/l's are simple (not open source, but the best I have found atm from trying similar apps) with postfix notificaiton when completed!! :)

was a reasonable outlay on the disks and array, however worth it knowing I have some redudancy to a certain level (you can start with 1 and dynamically add them, going from RAID0 through RAID5 or RAIDX)

NOTE: don't use cheap hardware or single disks as you will come undone...RPi's do the job for what I want...

Thanks for reply, I was using btsync on my phone too for awhile, however I found that a simple FTP app that could stream from the server was much better, atleast for iphone/ipod. Havent found that good ftp app for my android phone yet.

I bought some external intenso brand 4Tb disks that was a lot cheaper than buying the actual disks that was inside, WD green. I wonder if those disks could be the last pick if they have some kind of screening procedure at the hdd factory, ie vibration testing.

Tomorrow I get some SD cards to test with a RPi, do you know what clibent uses the most ram, rtorrent or transmission?

I use WD Red, they've come down in price alot since I bought them 3 years ago...

looking at my hosts...rtorrent seems to use more memory than transmisison, however I have ran rtorrent on a B+ Rpi for over 2 years without any issues ...the limitations are the bus speed for the device as its not able to handle high d/l speeds, i had to throttle so as that it wouldn't crash...however I have the latest RpiV2 with 4 cpu's/1Gb memory which doesn't  seem to be an issue now
