#Ps4 more disk space free
I have not noticed any performance degradation so far since making this change, though I still have plenty of free space on my drive at the moment.
#Ps4 more disk space ps3
The kernel normally changes the preference automatically as the percent fragmentation changes on the filesystem." However, since the PS3 uses a custom operating system and this documentation is from FreeBSD, I think it's best to manually set the space option anyway. Optimization for space has much higher overhead for file writes. The tunefs documentation says that "the file system can either try to minimize the time spent allocating blocks, or it can attempt to minimize the space fragmentation on the disk. That means that the filesystem will spend more time during writes to ensure the files are less fragmented, insinuating that it will shuffle blocks around to make contiguous space. Since we're allowing ourselves to fill almost the entire drive, these instructions also change the optimization mode to space. Time optimization is the default-and is used by the PS3-and allows for faster writes at the expense of potentially higher fragmentation (though generally only as the drive reaches capacity). UFS2 supports two write optimization modes: time and space. By changing the minimum free space, performance is not changed at all unless you choose to fill the drive completely.but at least you can now make that choice. It seems like this is a worthy tradeoff, especially since if you do notice any performance issues you can simply delete some games or other data to free up the space. However, it's unclear whether that only affects newly written-presumably more fragmented files-or all files. Also note that it says as free space drops to 0%, performance may be up to 3 times slower than normal. As free space approaches zero, throughput can degrade by up to a factor of three over the performance obtained at a 10% threshold." Note that these numbers are already higher than the 8% default that all UFS tools as well as Sony use. The tunefs documentation mentions that "the file system's ability to avoid fragmentation will be reduced when the total free space, including the reserve, drops below 15%. Now generally having this reserved space is not a bad thing, however the problem is that as drives grow larger, the amount of wasted space becomes larger than some of the smaller PS3's entire hard drives! Clearly that much isn't needed to prevent fragmentation.

This is why when you first install that shiny new 1.5TB hard drive you will see that not only is it only actually 1.36 TB because hard drive manufacturers really love counting in base 10, but you also lose another 111.4 GB. This is to reduce fragmentation and also prevent the drive from completely filling up, possibly freezing the computer.īy default, UFS2 reserves 8% of any drive's free space, in this case meaning it can't be used by the PS3 for installing games. Like other *nix file systems such as Ext2/3/4, UFS2 can reserve part of the drive's space to only be used by the system or the root user. While external drives used with the PS3 are all FAT32 formatted (or NTFS if you have CFW), the GameOS partition on the internal hard drive is formatted using the UFS2 filesystem with a layer of encryption on top. I believe the pros outweigh the cons though, and have been using this now without issue on my personal PS3 with a 1.5TB drive for a few days now, installing tons of games without a hitch.

This guide will explain how to reclaim that wasted space by manually modifying the metadata of the UFS2 formatted GameOS partition using Linux, as well as the potential cons (primarily performance, though I haven't experienced any performance issues yet myself). Turns out not only is it possible, but it's relatively easy thanks to some existing tools created by the community. From my searching online, I don't believe anyone has ever successfully unlocked that wasted space, so I decided to give it a shot. By default, even on custom firmware, the PS3 reserves 8% of your total internal hard drive space.
