Windows 7: Show us your SSD performance

Here again a typical Intel - Writes a lot slower than Reads, but overall very fast.

Congrats, nice scores

Although your read access time is a little slow.
Should be in the 0.08......range.


whs, his is writing faster than reading



As mentioned already, some SSD endurance tests have been seen and one is currently going.
SSD Write Endurance 25nm Vs 34nm

They reached the 20GB of host writes per day for 5 years, 36.5TB mark, and are still going strong.


Some interesting links in this thread.

Can this be true?


This site experimented to see how much data could be written to an X25-V before the NAND expired. They wrote to the device 24/7. (Seems they paused once every 12 hour to run TRIM from the toolbox).


Translation makes it hard to understand exactly how they ran the experiment, but they state:



A class (Sequential?)
  • 10~100KB 80% 10 ~ 100KB 80% (System thumbnails and the like)
  • 100~500KB 10%100 ~ 500KB accounted for 10% (JPG images and the like)
  • 1~5MB 5% 5% 1 ~ 5MB (big picture, MP3 and the like)
  • 5~45MB 5% 5% 5 ~ 45MB (video clips and the like)
Where B is random write categories: (Random?)
  • 1~100 100% 1 to 100 bytes of 100% (System log and the like)
In total there were able to achieve 0.73PB in 6,185 hours! That is a phenomenal amount of writes, which appears to be way over spec of 20GB of host writes per day for a min of 5 years.



Here is another one 0.86PB in 7,224 hours!


Does that come down to the work load or are Intel specs extremely conservative?

Looks like SSD endurance is much better than previously indicated.
The 20GB per day for 5 years = 36.5TB
The XS thread have reached that with a 80% Media Wearout Indicator, 80% life remaining.

One of the other threads linked above have reached 187.2TB with a 1% Media Wearout Indicator, 1% life remaining.

A whopping 789.9TB host writes before they stopped.

That's 432.8GB per day for 5 years, or 20GB per day for 108 years.

Guess we don't have to be so concerned about the amount of writes on our SSDs.

Intel Toolbox won't secure erase SSD.

When I get to Step 8 the SSD is no longer in the list -or- after clicking refresh it highlights I click on the box below it turns red and it tells me Security is enabled.
Which I just unplugged the SATA cable to disable in Step 6.
So I do it again and it does the same or disappears on refresh and I have to reboot to have it show again in Disk Management and in the Toolbox.

Does Disk 0 need a simple format for this to work?
That is the only option when right clicking the disk in area where I wrote SSD.

Also tried above in ACHI and IDE mode for Bios. IDE mode at least it tried to work.

I downloaded the Pmagic iso Essenbe suggested earlier in the thread.
I guess I'll burn it to CD tomorrow if no one comes up with any ideas.

Hopalong, I had the same problem. That's why I use parted Magic. But, with the toolbox I had to unplug the power cable to the SSD with the toolbox open. Then restart the computer, open the toolbox, then with the toolbox open plug the power cable back in, and click refresh. That was the only way I could get it to work. YMMV. The Intel website says it works much better with the Intel ahci driver installed, iastor. My SSD seems to work better with the msahci driver. It tests better with iastor but works better with msahci. Again, YMMV.

All right I will burn the Pmagic CD tomorrow. Too tired now.

I'm using the msahci driver. Couldn't find an Intel.

Try the toolbox. It may work like it did for me. Parted Magic is only 1 less step. Unplug the drive, boot into the CD, when fully loaded, plug it bsck in. There just seems there should be a simpler way. Not that you care, but I was told that when you start the computer, the system automatically locks all the drives. The only way to unlock them is to disconnect the drive, start the computer and plug it back in. Just with the toolbox, it all has to be done with the toolbox open. Don't ask me why. Cause I have no idea.

EDIT: The method I told you is in no manual. I am just stubborn and kept trying different ways, and that was the only way I could get it to work.

I think he installed it with the migration tool and the system reserved was not the sorrect size. It was only about 40GB or something. That will cause him problems later down the road. He will be unable to do system restores or backups.

Mine wouldnt SE with the MS AHCI dirivers, or in IDE mode.


You need to install the Intel AHCI driver (F6install ones, through device manager)

Reboot.
When it gives the message that security is enabled, unplug the SSD. (I pulled the SATA and power cable) and hook it back up after 3-4 seconds.
You can now SE the drive.

I have no idea what you are suggesting to do. The ASUS/Intel drivers have AHCI per mobo manual.
The mobo manual has no instructions for installing or activating this option.

Windows loads the Msahci automatically.

I have no idea what F6 does or when I would use it.
When Windows or Bios requests a F key be pressed I do otherwise I leave them alone since I don't know their function.

I am willing to try it.

Trying IDE mode was a suggestion I read on OCZ using Pmagic. Didn't figure it would work because it doesn't allow hot swapping which is needed to disable the Security setting- unplug and plug the SATA cable.
At that point it was worth a try.
