[SOLVED] How important is overprovisioning on an ssd these days?

[cattlecaller]

So after years of getting annoyed at how quickly my 850 Evo 500 gb used to fill up, I pulled the trigger and bought a 970 Evo 2 tb. But I realised that the "actual" space you have access to is already quite a bit less than 2 tb, and when you factor in overprovisioning in samsung magician, total accessible space in windows shows at 1.63 tb, which is MUCH less than i was hoping for, even factoring in the difference caused by considering a tb as 1000 gb vs 1024 gb etc.

But my question is, aren't modern ssds resilient to the factors that would require overprovisioning in the first place? And don't modern ssds hide some of its space for overprovisioning anyway? Hence why I'm assuming a 2000 gb ssd appears as having a total capacity of 1863 gb on magician.

That's what 2Tb look like for windows,this is with zero overprovisioning.

2 GB = 1.862645149 GiB
The thing is that 2Tb are quite big so until you fill it up completely you won't have any problems.

1863gb is right for a 2tb drive after formatting, that doesn't allow any over provisioning.

10% minimum should be your answer for trim to function properly without noticeably slowing the drive down. Most people would suggest 20%

Oh CRAP. When I bought the drive, I thought I was getting 2000 gb instead of 2048 gb. Now I realise that it was really 1860 gib being represented as 2000 gb. Buyers remorse....

Its not "remorse", that just a difference in reporting units.
And that is NOT OP.

Which is faster, 100kph or 62mph?

Base 10 vs Base 2
Human vs Computer.
2TB vs 1.81TB.

It's the same size drive.


Now, for your SSD, just leave 10-15% free space.
