as you can read there is a limitation of 25Mb file on MAID and, but I didn't wrote it, a limitation of how many PUTS (I trying to figure it out what is it exactly) you can do. SIA & STORJ have both 6 duplication, so you need to upload the file 6 time on SIA network to finish your upload. btw storj release a new version of the software today so it will change soon for them, and SIA do a lot of update too (I'm running on 1.0.1 version)
