    New life for my Dlink DNS 325. Not only a NAS with limited functionalities, but expanded also with unexpected server (MySQL ;)). Now is what I wanted to buy years ago. Also appreciated a real good spped increase respect to the original software. Not racomended to newbies due to the fact that some options are not comprhenive to a normal user.

    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
