I used Acronis Disk Director to do a direct clone of my C:\ windows 7 x64 drive from my Vertex 2 to my new Vertex 3 SSD (Just to show the drive software winstall everything is identical.)
I ran a performance test on Windows using the Windows Experience Index. The rating I am receiving when booting on the Vertex 2 is 7.5 While I am getting only a rating for the Vertex 3 of 6.9 My understanding is that the read/write speeds of the Vertex 2 is only up to 250MB/sec while the Vertex 3 is up to 500MB/sec.
Copying a single file (3GB in size) from the Vertex 3 to itself was getting speed of approx 70-80MB/sec This speed is no better (maybe worse) than what I got from the Vertex 2 I am connected via the SATA 3 port on the motherboard, using an SATA 3 cable
Is this issue caused by the drive cloning? Do I have a bad SSD?
You should run some benchmarks with utilities that will give you more detailed information then windows and report those results to help us figure out what is wrong. – Eric Fode – 2012-04-12T04:40:52.313
What are the sizes of the two drives? How much data did you clone? – David Schwartz – 2012-04-12T04:44:10.260
Both drives are 120GB and both have ~8 GB free - what benchmark prog are free and available for testing SSD drives? – Kairan – 2012-04-12T05:47:16.967
1Full drives are slow. Probably the old drive was a bit better optimized as Windows optimizes drives as they are used and the clone process was likely file by file in essentially random order. – David Schwartz – 2012-04-12T07:31:49.677
