Where my IOPS at?

[Vbgf]

Hello again guys! I've got a problem with my 840 Pro (or at least i think i do). I don't hit the promised IOPS. I think i''ve done everything to boost them as high as possible as far as options/settings are concerned. I'm posting the full Samsung Magician take on this to give you guys a better look at things:

 

Is this not right or is it normal? Thanks!

What IOPS are you getting?

What IOPS are you getting?

In image No2 it's shown.

55848 random reads / 97000

55384 random writes / 90000

Secure Erase the SSD. And format and reinstall OS. IOPS restored!

I will try that. Would update you guys when i'm done.

I have the exact same problem. Nothing Ive done, including a secure erase reformat reinstallation of Win8 has done anything. What motherboard and processor do you have?

Those SSDs are never EVER going to hit their maximums. That only happens when operations are carried out at a queue depth of (usually) 32 or more, which you almost never see in real-world applications outside of enterprise environments.

ASUS M4A87TD for mobo and AMD Phenom 965 x4 @ 4.0 (stable OC)

Then i should not do the reinstall? I mean my OS is pretty new like 2-3 months old.

You can if you want, a new install has other benefits. The point of the SSD is to be light years faster than a hard drive even in day-to-day tasks, which you should already be noticing.

Yes i do notice the difference, it's HUGE. Though will the "Secure erase" do me any good if i am reinstalling?

It will make the SSD behave more like it did when you got it in terms of performance, but it's not necessary. You might get a little more out of it.

Ok i might try that then.

I dont know... Im starting the think this is an AMD thing. Ive seen Intel guys get around this with fixes that dont work with my machine. BTW I have an 8350 with an MSI 990FXA-GD80 v2. Same problems. Are there any AMD users that have the benchamarks that they paid for with the 840 series?

Update: I have reinstalled the OS and reran the Samsung Magician test again and it was the same as in the picks. Then i noticed in Windows Update there was a thing standing out: an "AMD SATA controller". I checked that i want that installed aswell as all the security things... and after the reboot and all the installing of the updates i ran the Magician again. I've got consistant random reads to 66K IOPS from the previous 55-56K IOPS. Everythiing else was the same as far as margins were conserned. The OS is the same as last time (Win 7 ult x64) and my PC specs haven't changed. Also i have to mention that i did a Secure Erase via some linux thingy on my USB drive.
