    Большое спасибо! Это решение намного лучше заводской версии прошивки! Было неплохо добавить возможность изменять тему.

    Gave new life to my DNS-325-A2. The stock firmware from D-Link was not that bad but some add-ons were poor, for example aMule add-on. With Alt-F everything works out-of-the-box, my files were preserved and there are a number of add-ons that look interesting. I installed the aMule add-on and it appears to work well, coupled with its corresponding front-end "aMuleGui". The ability to define some shortcuts is really useful for saving time for starting/stopping some services when needed. Keep up the excellent work. Thank you Aldo

    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!
