I’m trying UE for the first time.
I have a 1TB external M.2 SSD that I installed it on and noticed a huge difference between the actual size and size on disk (36 GB → 78 GB).
When I formatted the disk I chose exFAT and left the allocation unit size to default - seems it was not the best idea.
I was wondering if you are also using an external SSD for UE and if so, what you found to be the best allocation unit size? (to minimize the wasted space, but also keep the read/write at a decent speed).
That difference does seem very high. I pretty much just stick to NTFS, so I apologize that I can’t go any deeper… but the standard exFAT allocation unit sizes, as recommended by Microsoft, are:
Yeah, as far as I know exFAT is more for file storage than everyday use.
But that’s just what I’ve heard. Let me know how it goes, please! That way if others have an issue similar to yours I can point them in the right direction!
@Mind-Brain
So far it works well! - went for NTFS and default allocation.
The installation was actually faster, the rest was pretty much the same, did not notice a difference.
I can’t pronounce myself yet if there would be a difference with medium/big or complex projects, as I need a new GPU - not enough VRAM to do much at the moment.
A bit of an unrelated topic, but maybe useful to someone out there: Windows may have some power saving stuff enabled that may cause UE or your computer to crash when using an external drive. (common for laptops, less common for desktop PCs)
Basically what happens is your external drive will be put in some sleep/idle mode quite fast if it’s not actively in use.
What I did to have it active at all times:
Device Manager > Universal Serial Bus Controllers > right click USB Root Hub > Properties > Power Management > uncheck Allow this computer to turn off this device to save power.
Edit Power Plan > Change Advanced Power Settings > USB Settings > USB Selective Suspend > Disabled
Edit Power Plan > Change Advanced Power Settings > Hard Disk > Turn off hard disk after > Set to 0 (a.k.a. Never)
