[Transcend]

I have separate external HDDs for Anime. Eventually, one for ridiculously long anime (Naru/Bleach/OnePiece/Gintama/etc) and the other for normal anime (<100eps). Recently bought 3TBS of space just for storage (YAY BOXING DAY!).

Folders within the EHDDs include.
-Watched
-Ongoing
-Done and pending watch (these are just folders with the anime's title floating outside of the watched folder)
-Not interested (these are single episodes, not in a folder, floating inside my anime folder)
-Food For Thought (Anime for teaching purposes, standalone oav's that invoke thought, etc)
-Nostalgia (Old anime that's just there for memory sake, Digimon/Pokemon/DBZ/Doraemon etc)

*- In my watched anime I put a letter in front of the folder to signify the level of enjoyment I had with the anime. B/D/G/E/M, Bad, Decent, Good, Excellent, Masterpiece.
