Show us your SSD performance

OK I understand. Thanks for explaining.

Good morning!

This is their observations and operational results on the Vertex. Post #384
http://www.xtremesystems.org/forums/showthread.php?271063-SSD-Write-Endurance-25nm-Vs-34nm/page16

The chart that was posted at above link shows normal speeds at benchmarking after proper idle period.

An update on my V2. I left it idling with no data on it after a secure erase. I then ran a series of iometer based benchmarks. The advantage of the benchmark is that I can incrementally increase the size of the test file from 1GB to 12GB.

I ran each benchmark run sequentially, starting with 0 fill for the first run. All following runs were done with non compressible.

In total 30GB of non compressible data & 1GB of 0 fill.

After this barrage I let Anvil's Endurance app run. Within 2.91 hours or 383.17Gb the drive was throttled down to 6.71MB/s.

So, it seems that even a small amount of idle time will enable performance to get back, but if you sustain the writes you end up back being throttled.

Good news in a way. If I leave the drive to idle for a week or so and don't write excessively I should not experience any slowdowns.

That's the end of the V2 in this thread

So they had to slam it with almost 4GB's continuous writes to make it throttle again.

I just thought I would point out their observation and actual results and cure to get it going again.

I did not want our readers to think they killed it out right by any of our comments in this thread..

As I understand it, that confirms what I have read on several reviews about the Vertex2. When you write to the drive, it encrypts and compresses the data. When you do a secure erase, it does not erase anything. What it does is change the encryption key. Thus, the data is not recoverable, but it is still there. It depends on trim and garbage collection to remove the old data. That would explain why, in this test, a secure erase did not restore the drive, but leaving it at idle for garbage collection did. Apparently, a secure erase simply marks the data as removable.

Like you and I decided to do on my Intel with checkdisk if you remember since we could not get secure erase to work.
Of course we were only writing over the origial install.
Not a packed full SSD.

Mike, I'm glad you pointed that out because I thought they had killed it. I guess it pays to read the entire thread instead of just the overview posts.

How is youe SSD running now?

That was why I posted the info. Did not want others to do the same.

They just could not continue the testing.
It would take 10 years to run the test at 7GB of writes.

My Intel works great for me.

There are faster ones on the market in Benchmarking but in actual "real world" use I'll bet this one is just as fast or to close to notice a difference.

That is what we need. Software to read usage though the day or the week.
Then give results of writes and reads to what you actually used it for.

For the week.
You did a 1000 reads this size- Avg. speed was ???
498 writes this size- Avg speed ???
5 this size etc.

That would be a good comparison.

Differences in actual use that came down to tenths or hundredths of a second I would venture to guess.

Last Tuesdays 18 Windows updates would have been an interesting mix.

I got all my Intel hardware updated last Sunday with Driver Max that A Guy posted.
That was where I finally was able to download the iastor driver properly.

The free version you can get 2 downloads per day so I updated and finished the entire P55/ Chipset and everything else I needed.

All my ASUS software still works. ASUS is just to lazy to update their downloads unfortunately.

No noticeable improvements in performance but compatability should be improved. Two year old drivers is a problem waiting to happen.

Are you satisfied with the performance you are getting? And is it what you were expecting?

Yeah I'm satisfied with performance.

Honestly when I first installed it I noticed an improvement but not the huge improvement everyone says an SSD gives.

Now I have a very fast system with decent internet speeds to begin with.

When I REALLY noticed the difference was when I reimaged Win 7 back to the HDD so we could do the Secure Erase and reinstall to the SSD.
The HDD was SO SLOW!!!!! It was like is any of this stuff going to load sometime today!
I felt like the SSD was two steps forward when I started using it.
The HDD was 8 steps backwards using it temporarily for a few hours.

So my complaints disappeared after that. LOL
