    replaced a Synology NAS, which had a super slow processor. With this, transfers and transcoding are quick. I bought it to allow chromecasting, but this is not always available for some reason. It's quiet, but it does have a clicking noise that sometimes wakes me when I sleep in that room. I'm not sure why it's powering up in the middle of the night. I haven't used all the features yet, such as surveillance cameras and remote storage, but plan to.

  • Upgrade from Intel NAS

    Had been looking for a more robust NAS to upgrade from an older Intel NAS. Read about the QNAP series and didn't need the display so went with this one. You do need to read the setup directions, but once it is running you don't need to do much else. Works flawlessly and is fast. Installed 4 8tb WD NAS drives so won't run out of room anytime soon.

  • Great home NAS/cloud solution

    Sudden price drop announced in a 24 hr sale so I had to get it. I've been looking to implement my own cheaper solution but the learning curve involved was off-putting. QNAP has many great products and this one is a great combination of ease, versatility, and expandability. Granted, you have to buy your own drives, but it's modular and unless you want full mirroring right away, you only need to get one at a time. Running Plex media server on this and it has really been great. I also upgraded the onboard RAM after purchase with third party soDIMMs, just check the compatibilities at QNAP's website. This replaced a 4GB external WD MyBook.
