QNAP already added nearly every thinkable feature to their NAS firmwares. To make a new series innovation had to be found elsewhere. QNAP decided to double the capacity in their TS-409 Pro and add features to utilize this space. The four disks that the TS-409 Pro houses can therefore be put in any RAID level including 6. Besides adding RAID 5 and 6 support QNAP shows they take their RAID arrays seriously by adding support for online expansion and RAID migration. Combined with the already proven ease of use and list of software features the TS-409 Pro Turbostation promises to be a solid product.
