Question How slow would a Gen3 NVMe SSD get when it is near full ?

[knowledge2121]

If I fill 95% of my DRAM-less 2TB NVMe SSD with data, how slow would the drive get ?

Specs:

Sequential: Read/Write: up to 2100/1600 MB/s
IOPS: Read/Write: 220K/200K IOPS

I don't need an exact speed, I want to know how slow the drive gets roughly. just give me an estimate ....

As the device approaches full, it can become painfully slow.
My Daughter in law complained about her slow pc.
It took 30 minutes to boot up because the drive had so few available nand blocks to handle the writes required.
I cloned the drive to a larger ssd and the relief was complete.
95% is about the point where I think one should consider replacing with a larger ssd.
Particularly if the drive is updated actively.

Hey there,

It's often suggested to keep at least 25% of the space free. SSD's without dram suffer more.

This is not an OS drive though, I will install my games to this drive. so mostly write once, read forever kinda situation...SSDs with DRAM also suffer from this, correct ?

Read will be OK.
But, loading a new game might take days if the drive is sufficiently full.
Best to take care of the situation before it becomes an emergency.
