P64 too slow?

Hi there,

 

I just received my Corsair P64 SSD two days ago :)

The new firmware was already installed when I got it and I installed Windows 7 without problems.

 

Heres a screenshot from CrystalDiskMark:

Here's my CrystalDiskMark:

Well, a bit too slow at reading, isn't it?

 

I already stopped my Kaspersky InternetSecurity, but the results are quite the same.

 

Whan can I do to improve the speed?

Your speeds are far better than mine (I'm also on VBM19C1Q). I've reported slow speeds in another thread - sorry for hijacking - but I think my post is appropriate in that it shows a similar issue.

 

Hopefully this screenshot shows everything stats-wise;

My P64 has started to feel much slower than it did ~1 week ago when I updated the firmware and reinstalled Windows 7; although it has never been as fast as my friend's P128 by a long long way. I think my drive has crap flash memory in it - maybe yours came from the same batch?! Am very interested to see what Ram Guy says, as I e-mailed him not long ago but didn't hear back.

 

Just as a PS, I have issued the Secure Erase command twice now (as detailed in my other thread) and all forms of caching are disabled, as is page file and defragmentation. As far as I can tell, I'm looking after my SSD well and follow all the common advice on looking after SSDs with Win7 installed. Although I'm prepared to image my drive and issue the command AGAIN, I can't see it helping.

The published results for P-64 are:

220 MB/s sequential read

120 MB/s sequential write

So since you have the drive as the Boot drive with the O.S. loaded on it that may be normal.

But you can image the drive to another drive then secure erase it with Parted magic and then quick format with a 32K allocation and test it again as second drive.

Yes, but I guess there are lots of people out here, who also use their SSD with Win7 as system drive. And they got better results.

Could someone who owns a P64 and is using it as boot drive upload a few benches?

 

Thanks in advance.

Wow Skywálker01, you have a good P64 :P my P64 is also my boot/system drive, see my benchies above.

 

I'm going to image off everything, secure erase, and test it with this 32K allocation business to see if (as a non system drive) it can do any better. Will post back results.

After reading everyone else's posts, I thought I would check my P64 which is used as my system boot drive. My PC was built in late Nov 2009, therefore the drive has had almost 2 months use. Windows 7 set the allocation size to 4096, not 32k. Results are:

These results so great variation with those posted with others - slower on some reads and writes, and faster on others!

Just for interest, I thought I would check my stats again - powered on the machine and ran the test. These are the results - sudden improvements in write performance. Probably goes to show that we shouldn't get to hung up in testing performance of these drives!;)::
