CrystalDiskMark 3.0 TestsCrystalDiskMark 3.0 is a file transfer and operational bandwidth benchmark tool from Crystal Dew World that offers performance transfer speed results using sequential, 512KB random, and 4KB random samples. For our test results chart below, the 4KB 32-Queue Depth read and write performance was measured using a 1000MB space. CrystalDiskMark requires that an active partition be set on the drive being tested, and all drives are formatted with NTFS on the Intel P67 chipset configured to use AHCI-mode. Benchmark Reviews uses CrystalDiskMark to illustrate operational IOPS performance with multiple threads. In addition to our other tests, this benchmark allows us to determine operational bandwidth under heavy load. CrystalDiskMark uses compressed data in its benchmark tests, so sequential file transfer speeds appear lower compared to those tested with other tools using uncompressed data. This section concentrates on operational IOPS performance using compressed data. CrystalDiskMark 3.0 reports sequential speeds reaching 485.5 MB/s reads and 312.7 MB/s writes. 512K test results reached 427.5 MB/s read and 312.1 MB/s write performance. 4K tests produced 33.0 read and 78.84 write performance.
Maximum 4KB IOPS performance results at queue depth 32 are reported in the chart below. These values represent the performance levels for several enthusiast-level storage solutions, and illustrates which products offer the best operational performance under load:
In the next section, we continue our testing using Iometer to measure input/output performance...

Great review, and I enjoyed reading about your benchmark selections and reasoning. This latest generation of SSDs sure provide amazing performance.
to me, the prices on the patriot pyro SSD's look good, compared to what i have seen with other SSD's, which, incidentally, are too expensive, for me..
Can I assume that if I have already done a W7 install on a HD that I can use this procedure to move W7 over to the ssd if I purchase one? I am new to W7 and system image? Currently all I have installed on a new build is the W7 OS..Thanks
Do you reply to email also??? or do I check back here...guess I will find out if you respond to my email...preferred...thanks

Some imaging software is offset aware for SSDs and some is not. If your software does not work properly with an SSD and you create a hard drive image, when you restore the image to the SSD you will have the wrong offset.
Some imaging software will use whatever offset is in the image. Under these conditions a restore will provide the wrong offset. If the image was made from an SSD in the first place, then it should restore the correct offset.
Some imaging software has been updated so that it will use the correct offset when restoring even a hard drive image to an SSD.
This all depends on the software. You MUST check your software and if necessary contact the publisher and find out how it handles offsets. If you restore a hard drive image to an SSD with the incorrect offset, as far as I know the only way to correct it is to completely do a fresh install of Windows 7. I have seen people claim they can correct the offset after an incorrect image restore, but I tried it and the performance was not what it should have been. I had to load the recovery console, command line interface and run the diskpart software to format the drive and apply the correct offset.
All that can be avoided in two ways:
1: Do a fresh clean install to begin with and windows 7 will do everything correctly.
or
2: Create and restore your hard drive image using image software that is SSD offset aware.
handy to have for anyone playing with SSD's, and you re-use it once you buy it. There's other ways to re-align, but for $30 the Paragon Tool will save you a lot of headaches.
