SSD Free Space Question
Hey guys, I have a 250GB SSD (NVME). How much free space should I leave on the drive? So as of right now for example, I have 80GB FREE and that drive only has my OS, RUST (which is only like 8GB) and AC:O. If I install another AAA title I could be left with 20 to 30 GB left. Is that bad?

20-30GB of free space is quite enough, considering the SSD doesn't offer that much space in total.
10% is minimum.. 20-30% is optimal

Rule of thumb is keeping 30% free. So, with your current drive, up to 175GB, keeping 75GB free.
Below that and you may notice a degradation in performance due to how SSDs work.
Sata SSDs are very cheap right now.
If practical I suggest:
A hard drive with enough space to put lots of games on - 1TB at least
The cheapest SSD you can get - probably a 120GB one.
SSD caching software - there are many options the best is primocache or maybe velossd which works and the cheapest I know of.
There is little difference with Sata & NVMe drive game loading times it seems.

This ^. Try to keep 25-30% of total space free. Total space always equals power of 2. So, if your SSD labeled as 240GB its real capacity is 256GiB.
I consider 15% of free total space as absolutely minimal.
a Typical easy rule, however much max pagefile you have, double it. so in the area of 30GB free should suffice, but keep in mind possible space needed for future windows updates.

If thats all you have on your SSD, have you done a disk cleanup? If not you may have more free than you think.

Get a secondary drive if you can, 1 or 2TB SSHD/HDD's are nicely priced these days.

Games will only benefit from an SSD if they actually have data that needs those speeds, such as large open world games, Battlefield series etc so on. Otherwise a game is perfectly fine on an SSHD/HDD.

No.

Sidenote: there's also something called over provisioning, depending on drive model it has some factory locked, or maybe via partioning extra.

Do not spread misinformation, please.

6 Things You Shouldn’t Do With Solid-State Drives
Don’t Fill Them to Capacity

You should leave some free space on your solid-state drive or its write performance will slow down dramatically. This may be surprising, but it’s actually fairly simple to understand.

When an SSD has a lot of free space, it has a lot of empty blocks. When you go to write a file, it writes that file’s data into the empty blocks. more>

20-30gb regardless of drive size, is a must these days as needed in order to have room for OS updates.

Its not Misinformation, and it isnt even a bad recommendation
Its common knowledge that having low space on an SSD can affect performance, so You please dont spread misinformation.

And its even stated on the website above

Don’t Fill Them to Capacity
You should leave some free space on your solid-state drive or its write performance will slow down dramatically. This may be surprising, but it’s actually fairly simple to understand.
When an SSD has a lot of free space, it has a lot of empty blocks. When you go to write a file, it writes that file’s data into the empty blocks.


When an SSD has little free space, it has a lot of partially filled blocks. When you go to write a file, it will have to read the partially filled block into its cache, modify the partially-filled block with the new data, and then write it back to the hard drive. This will need to happen with every block the file must be written to.
In other words, writing to an empty block is fairly quick, but writing to a partially-filled block involves reading the partially-filled block, modifying its value, and then writing it back. Repeat this many, many times for each file you write to the drive as the file will likely consume many blocks.
As a result of its benchmarks, Anandtech recommends that you “plan on using only about 75% of its capacity if you want a good balance between performance consistency and capacity.” In other words, set aside 25% of your drive and don’t write to it. Only use up to 75% of your drive’s free space and you should maintain ideal performance. You’ll see write performance start to slow down as you go above that mark.

So yeah, thanks.

Like CJ said...

Again this is for OS drive and any Games drives. For say a usb flash drive, sure using its full space up is fine.
I think keeping ~25% free space is dumb. Does that mean that if i have a 2tb ssd i have to keep 500gb free??? Doesnt make any sense. I just keep 20-30gb free on all my ssds no matter how big they are and i have never experienced any slowdowns.

You pretty much answered your own question
20-30GB, which is what i said as an example

That is your choice. But do not complain later when the performance of the drive decreases. It seems you both with CJ do not understand how SSD works.
