The BQ Aquaris E4.5 (what a fvking mouthful) has 8GB of internal NAND/SSD memory.

That converts to about 7.4GB of usable memory.
And from that, there is about 5.3GB accessible to the user on the phone.
Hence, the Ubuntu Phone ROM itself uses around 2.1GB's.

In other words, its more memory used than FirefoxOS and barebones Android (~1GB). Around the same memory used as light Android builds (2.0-2.5GB). And much less memory than Bloated Android and iOS (4.0-6.0GB). In layman's terms, its pretty neat !



So on the Meizu MX4 Ubuntu Edition, it'll have a 16GB capacity with no option to expand it. The amount available to the user will probably be around the 12.0GB to 13.0GB margin. And to me, that's pathetic for a high-end phone. Anything less than 25GB is pathetic for the high end market.

A rule of thumb that I generally use for ARM devices:
4GB - Enough for OS - but not enough for personal use
8GB - Low End - enough for system and apps, but no photos/music/videos/high-end games
16GB - Mid Range - enough for system/apps/photos/music but not videos or high-end games
32GB - Mid Range - enough for system/apps/photos/music/videos/high-end games but is a bit limited
64GB - High End - enough for system/app/photos/music/videos/games with lots of freedom

Unless its an x86 PC:
32GB - Enough for OS
64GB - Low End
128GB - Mid Range
256GB - High End



I hope I have been of some use, smash that Thanks button : )
