do all ssd solid state drives slow down after the get 50% full ?

post #1 of 7
Thread Starter 
i recently received a refurbished ocz vector 512gb ssd as a RMA replacement for my ocz vertex 450 512gb ssd that died . i read a review of the ocz vector 256gb ssd on andatech.com and they say that when the 256gb ssd reaches 50% of it capacity left that it slows down a lot . i have the 512gb version does this mean my ssd will slow down a lot when it reaches 50% of its capacity also ? i have been looking in to this subject and i found that ssd solid state drives slow down once they reach a certain amount of its capacity . when i had my ocz vertex 450 512gb ssd i never filled it past 50% of its capacity so i would not know if it slowed down once it reached that point . but i also used to have a crucial m4 256gb ssd and i used to fill it up to about 85% 90% of its capacity and i did not notice it slow down at all . so i am a little confused do all ssd solid state drives slow down once they reach a certain percentage of there capacity or only certain ones do ?

I cant answer that, I have heard the same thing but that was around 2 years ago, it may have been the controller in older gen SSD's, wait for one of the gurus to get in here.

All SSD's slow down at 75% but performance hit isn't noticeable until you get to 90% and above, unless you have space over provisioned already. If not you should leave at least 10% of the drive empty.

i got an ocz vertex 3 128GB sitting on the desk near me, it failed big time after about 2 years of fairly standard usage (i have other drives for moving large files around, so it was only used to install and uninstall programs, even all my documents/downloads/desktop was on another drive. It didn't actually see that much action, but was about 80% full the majority of the time.

maybe thats why my corsair still runs good it has 8 gigs already over provisied and you can manauly increase it if you want using the corsiar ssd toolbox tho i do try to keep it at 50-60% full no more.
