My QNAP TS-509 Pro is using
5 x 1tb Western Digital RE3 enterprise raid drives in EXT4 RAID5. This was my first nas, and i may have jumped the gun when getting the expensive enterprise drives.
I recently acquired a new QNAP TS-659 Pro with Atom 1.8 GHZ dual core cpu. It has
4 x 2tb Samsung F3 desktop drives in EXT4 raid5. They work perfectly fine with no errors. This time around after careful study, i got these 2tb desktop drives which work fine in raid. Why pay for expensive 1tb when you can get cheap 2tb that work fine in raid ?
So now i just turn off my 509 since i use that for backup. The 659 is on 24/7 as my webserver, media storage etc
If your getting drives i recommend the Samsung F3 2tb for best value/performance. There is a newer Samsung F4 2tb just came out this month, however it is using the new 4k sector advance format. If you want to go down that route, investigate whether your NAS supports 4k sector drive or will it degrade your performance.
My preference is QNAP, so i would recommend 4 bay minimum if you want to get QNAP so you can do raid 5 or raid 6. I recommend raid5 since the performance penalty isn't as high as raid6.
PS: Remember with good internet you must have good storage, AND A backup

Bro thanks for guiding me.

I will take you as my sifu.
Haha easy to have experienced ppl like to guide me along.
I think I have gone the wrong way as I am using mostly green drives now.
Is high performance drive a must for setting raid NAS? Do I have to change them to performance drive like yours?
OT: One of my fren failed to stream media via his home plug to the network media player. What home plug do you use?
