QNAP: RAID size and 2TB drive support?

Per the press release on March 25, its all good finally after much waiting and forum discussion. :-)

"Western Digital Caviar Green 2TB (WD20EADS) SATA hard drive is now supported by the entire TS-109/ 209/ 409/ 509/ 439/ 639/ 809 /809U-RP and the latest TS-119/ 219 Turbo NAS series."

"The maximum capacity can be extended up to a total of 16TB now on a TS-809 or 809U-RP' says Andy Chuo, Product Manager from QNAP."

Also, the latest compatibility list published April 22 has the WD20EADS in the list (and notably without any extra remarks!):

Myself, the server just arrived yesterday and I'm currently waiting impatiently for the RAID 6 rebuild to finish on 7x2TB. Currently simultaneously moving files from the front-USB backup (figured I may as well test it) off the final 2TB drive before I add it into the full RAID set.

At 7x2TB its showing me just below 10TB available ... yeah, RAID 6 means (n-2 disks) with each 2TB showing up only as 1.8TB. I just may decide to make it RAID 5 instead when all is done.


  1. How is it going - is it working well? I am considering the 809U-RP with 8 of the 2TB WD's any issues with your setup?

  2. No issues at all. One thing I realized after RAID6 is that 2TB of wasted space is exactly that. If you're not running Fort Knox best to use RAID5.

  3. The post shared here is useful and attractive, i like the hard work done on the topic to make it impressive. Thanks you.
