We know nothing about your system and in particular your disk setup and how you maintain it. You know, there is this thing called disk fragmentation and only a handful of damaged/ fragmented clusters can easily reduce disk space for large, contiguous files...
Thank you Mylenium. All this time I have been absolutely convinced that you don't need to defragment SSDs. Is this a complete misunderstanding? Even if you do though, I have Windows 8 (not 8.1) which is doing that once a week automatically (apparently even to SSDs).
Are you saying that the 30GB disk cache set up works like a contiguous file?
i7 3930k (12 virtual cores) on P9X79 Deluxe
2 x 120GB Force GT Raid 0 SSD on SATA 6gb/s is my boot drive as well as where I keep programs and the disk cache. I do a disk clean up to remove temp files a couple of times a week but that's all.
1 x 3TB Barracuda on on SATA 6gb/s for back ups and exports
3TB Lacie on USB 3 for source video and project files
2TB Lacie on USB 3 for archive projects
I'll try a manual defrag of my RAID 0 SSDs now.
Ok, so luckily I looked up defragmenting SSDs before actually doing it. It seems that it is really not recommended or necessary according to a cursory search.
Are you telling me I should try defragmenting my RAID 0 SSDs regardless?
