    it's a very good and stable project if you follow the installation guide step by step, it's fairly simple to setup all the necessary config before you will enjoy a brand new budget gigabit DNS with up to 3 HDD support. the speed before and after switch to Alt-F is about 4~6x speed jump... max out about 30-40MB/s =240~320Mbits.. over a gigabit lan. which is very good.. i would assume using ssd hdd will achieve higher speed.. though may also be capped by the DNS hardware itself (ram, cpu etc..) learn to use ssh commands to access the driver and you will also be able to transfer files to usb3 drives very quickly.. compared to over the gigabit lan.. wonder if there is a app that will allow testing of file transfer speed on alt-f? think there is.. just need to search a bit i guess

    I was about to scrap both my DLINK DNS-321 machines due to insufficient capacity. Thanks to the Alt-F project I can now drop in multiple 3TB or 4TB drives and extend their life. Interface is perfect and minimal. Speed is very good if not better than original DLINK firmware. Ease of install - Just Upload new firmware! In my case the hardware was A2. Worth following instructions. 15 minutes setup start to finish. A very useful project, and great service. THANK YOU ALT-F!

    Absolutely brilliant! I'd had my DNS-320L just a week before I became frustrated with the lack of functionality and the clunky UI. After a bit of searching I discovered Alt-F and it's transformed my budget NAS into a very useful little unit - not to mention how much snappier and responsive the UI is compared to the D-Link firmware. In no time I had it up and running with NZBGet, Sickbeard and Couch Potato and I can SSH to it from anywhere to see what it's up to. It's not necessary but I copied all my data off the existing disk first and let Alt-F format it before copying it back. The partitioning seems a lot tidier under Alt-F and the orange lights which were permanently illuminated are now showing the correct state. Awesome project - thank you!
