I have owned a Synology DS212j for a while, and have been happily filling it with all the usual stuff.
When i purchased the NAS, i added a 2tb Seagate Barracuda, which at the time was £120, and so with the wife not understanding the need for 'another expensive box', i only purchased one hard drive.
So now i realise the importance of having two drives, for back-up etc, because we all have such large collections these days and would be heartbroken to lose it all.
As there are better drives around now (greener, quieter, etc), can i add another 2tb drive, even though it may be a different brand, have a different spin speed, or cache size?
I'm not wanting to buy the exact same one as it is still hovering around the £100 mark, and there are bargains to be had for £60 -£70.
