Komplete Ultimate 11 Install "Size on Disk" vs "Size"?

callahan09 · Dec 28, 2017

I've got most of the libraries for Komplete Ultimate 11 installed (I couldn't fit all of them on my hard drive), and it takes up 461 GB "Size on Disk" according to Windows 10, but says the "Size" is only 307 GB?

I know that this effectively means that the total amount of space it's truly taking up on my hard drive IS the larger number ("Size on Disk"), but if the actual file sizes are only 307 GB, why is the Size On Disk so much bigger (about 50% larger!)?

Is this normal? Or do I have the wrong formatting on my hard drive or something?

It's a 512 Gb (476 GB) SSD formatted in exFAT with 512 Bytes/Sector cluster size setting. I'm not sure about this kind of thing, but maybe either exFAT is the wrong formatting? I don't think it's possible to change the sector size, is it? So is this pretty much just the way it's going to be?

Looks like the big difference between the "Size" and "Size on Disk" numbers is most likely related to how the drive is formatted:

ExFAT is not a good idea, especially for an SSD.

ExFAT is good for small partitions that don't carry any important data, it is just as fragile as FAT32 and other non-journaling filesystems.
FAT32 Is good for compatibility with almost any device, which usually outweighs it's fragility.

NTFS will be faster, will support TRIM (critical for SSDs), there is better filesystem caching, there is metadata to make some filesystem accesses instant. Most importantly though, NTFS is a journaling filesystem. That means, in simplest terms, that every operation is first recorded to the journal before it is actually carried on the data section of the disk. If there is sudden powerless, BSoD, or other unexpected mishap, even if the system was writing data to the filesystem, you have a very high chance of recovering most if not all of the data.

The FAT family of filesystems are extremely simple in operation. This sound good at first, especially for SSDs, but once you look into it further you can see it's folly. Basically FAT filesystems have 2 parts to them. An index, and a big pile of clusters. Kind of like a big ass book with a nice table of contents which is easy to read, but then followed by eleven thousand pages of size-1 font print with no pictures. To access each and every file, the system has to look through the index, one-by-one until it finds what it wants. Then it's gotta zoom to that cluster and hope that the data it expects I actually there. If it isn't, to bad so sad, files gone forever.
