Western Digital or Seagate

^series like dennou coil 1080p ranges around 45GB, ultra long series like naruto and bleach even at 720p goes around 40-70GB, at best lets split it to seasons to lessen the huge chunks =P
anyway 3TB is plenty for 1080p series averaging 40GB each, which is around 75series.

I guess you are wrong with that one :)
Anime does tend to take up a lot of space...
I bought a 2TB seagate and i have stored 50 series on it till now... over 1 TB of space is gone and i have like 300-400 series more to download... i usually download full HD with FLAC audio so you can pretty much imagine what kind of storage space i need.
i don't think even a 18TB NAS would hold that kind of a collection...

Average series being 15-20gb at 6TB will allow you to store 307 series at 20GB a piece and i think that is generous as i think most are around 15gb

So you mean to say i should get a normal WD HDD?
And i never said i don't download other stuff which is not 1080p FLAC...
i download a lot of blacklisted stuff in 1080p if available or SD if not

If you configure things correctly, yes, that is right. Different RAID configurations can handle different levels of loss, while also improving the performance of your disks by using them all at the same time. For example, the most common RAID level is RAID 5, where you can lose a single disk and still keep all your data. In RAID 5, one disk is kept on stand-by as a spare. You write to every disk simultaneously (though you don't get any extra performance from the extra disk), but you don't read from the spare disk unless one of the disks dies. So, if you have four disks, your performance can reach up to three times the read/write speeds of a single disk.
Basically, RAID gives you the advantage of failure tolerance and performance enhancement for the tradeoff of losing a certain number of disks worth of disk space. You can read more about it on Wikipedia.

After all my data would be safe even if my disk goes bad. :D

I built a small computer for my first NAS. It consisted of an Intel Atom board and CPU (about $90), 1GB RAM (about $30), one 500GB boot disk (about $50), four Samsung 1.5TB disks (about $180 each), a cheap 4-port RAID card (about $20), and a cheap case (about $50). Prices are what they were at the time (about two years ago) and in CAD; obviously they have dropped considerably since then. I used software RAID through Linux so I did not use any sort of hardware-based RAID. It acts essentially as an expansion for SATA ports, since the board only had two SATA ports. I went with RAID 5, which gave me 4.5TB (about 4.1TiB) of space.
These days you can get Atom-based mobos for roughly the same price but with considerably better performance, not to mention everything else is a lot cheaper. You can get 3TB disks for less than $180.
My current server cost considerably more, because I was looking to build a server that handles more than just NAS functionality. My NAS is actually still running, sitting on the network, seeding a small number of files to oblivion, but fileserver, web server, and general usage tasks have been taken over. When I first got it, I got an Intel i5 2400 ($200), Gigabyte mobo ($130), 8GB RAM ($75), 60GB SSD ($120), pedestal server case ($60), and 6 Hitachi 3TB disks ($120 each, minus $10 rebate). I got lucky with the disks and managed to buy them a couple months before the big Thailand flood that caused HDD prices to skyrocket.
(Note: All prices are approximate)
Since my initial purchase, I have replaced the SSD because it failed on me. The new one is 120GB and SATA III, much faster and more reliable than the old one; cost me around $200. I've upgraded the RAM to 32GB, which was also around $200.
Anyway, it definitely goes without saying that prebuilts are quite expensive and commissioning someone to build something for you is also expensive.

That's pretty cool. It builds and rebuilds the array as you expand? Does it do something similar to Drobo?

What you initially purchased can be done... i can buy almost the same thing for a lesser price and add 2 Hard Disks of 3TB each... rest everything being the same..
But if i buy i'll buy a better case which has a significantly more number of bays... so that i can keep using it after i upgrade my system
It would roughly cost me $800.
Not bad i'd say.

Yes, hybrid synology raid is pretty interesting its not like your standard raid5 where you lose a whole drive for redundancy if you use it you can read about it here. http://forum.synology.com/wiki/index.php/What_is_Synology_Hybrid_RAID%3F You can run old school raid5 levels on the unit if you like but its back to one drive at least being used for redundancy
But yes it will rebuild and expand anytime you pop a drive out or insert a new one you dont have to flag it or anything. if you had 4 1tb drives in it. you could pop out anyone and replace it with a 3tb drive and it would expand and rebuild to use the full 3tb of the drive will still using the other 3 1tb drives if you ran the hybrid mode. For home use and small business I recommend them highly. If you are a DIY type of person there are cheaper solutions that are not so easily managed. Im sure you have tried to expand and ext3 FS its not easy and not the safest thing either. but ZFS is now nice enough to replace mode home setups unless using hardware raid controllers.
