Overprovisoning

Chimp Paradox · 8 Jan 2015 at 20:59

Two 1TB SSD arrived through the post today. Before I format them, whats the deal with over provisioning? What size should I actually format?

Thanks!

Let windows format them and away you go?

overprovisioning reserves ssd space for the controller to maintain the drive

its not really needed tbh,esp if its a new fresh install with plenty room

if you install the Samsung magician software you can st it through that.

I have it set on my 250GB evo 840, on mine is recommended I set 23.29GB unallocated space which I have done

from the software it states its for

over provisioning (OP) optimises the performance and life span of the SSD. a small amound of disk space is required by the controller

Ah awesome, thanks. I havent used magican yet but all my drives are samsung, so will investigate

I find magician really easy to use, so you should definitely check it out!

Chimp Paradox · 9 Jan 2015 at 17:22

done this today. Very easy. Anyone use RAPID for the OS drive?

wazza300 · 9 Jan 2015 at 17:29

ive used it in the past,not atm

again it didn't seem to improve anything for me

ED209 · 9 Jan 2015 at 18:30

I read up about rapid mode, a lot people said it made no difference and the results where not correct anyway.

screen shot of speed tests with it enabled.

and this is with the drive connected to a sata 2 port, cant see any difference with it on or off

Rroff · 9 Jan 2015 at 18:34

RAPID mode seems to have some minor realworld benefits if your on a slow link SATA1/2 but very limited realworld gains on "SATA3" though the very latest update seems to marginally improve its usefulness but at the end of the day it doesn't do anything earth shattering for the most part.

anyone know why overprovising isnt an option for my OS drive?

I had a issue before where it wouldn't work through the software.

had to shrink the OS volume in disk management and then it worked after that fine

I have over provisioning enabled on both my Samsung evo 840 drives.

ones for storage and the other is for the OS

Chimp Paradox · 10 Jan 2015 at 07:51

still cant do it, though isnt shrinking it like that overprovising anyway?

ED209 · 10 Jan 2015 at 08:28

the 23.29GB it needs it unallocated raw data so has no partition created or drive letter etc and just sits there as space not to use

if you look at the screen shot below, you will see the E drive and C drive both have 23.29GB unallocated, this is for OP

Chimp Paradox · 10 Jan 2015 at 09:35

Thats what I did, but magican still wont let me set OP even after creating that unallocated space

ED209 · 10 Jan 2015 at 10:10

the "set op" and "clear op" buttons, are they both greyed out or can you click either of them?

OLDPHART · 10 Jan 2015 at 10:44

Have a 256 830 SSD for OS+Apps and a 500GB 840 EVO Games both overprovisioned.

With 2 SSD's you can only rapid mode one.

Its odd:

going from that screen shot OP is already enabled.

where you have the gray bit at the end of the blue line it states OP under it. set OP button in greyed out because its already been set.

looks exactly the same as my first screen shot posted in this thread

Chimp Paradox · 10 Jan 2015 at 13:47

the problem is, that OP happened automatically when i shrinked in disk management. And if you look at the number, the OP amount isnt quite what it recommend OP to be, slightly less tan 10 percent.
