Performance over time
In recent weeks one of the primary focuses for us at PC Perspective has been to look at long term performance of solid state drives.  The first result of that research showed up last week in our look at long term SSD performance on the Intel X25-m series.  Obviously we are now doing additional testing on all of our SSDs to see how they fall into line with performance over time. 

I have provided some preliminary results below though we will have a more in-depth look at performance in near future.

After our suite of tests, this is what HDTach reported

You will remember that our initial HDTach results were 208/172 MB/s (for read/write, respectively) so a drop to 177/111 is definitely a noticeable change.

ATTO results are a bit lower as well but not nearly as much

However, running ATTO benchmark immediately after the HDTach run above, you can see that the Summit is still performing well; at least in some usage models and benchmarks.

After a couple of “full” HDTach runs, the drive has equalized

As we discussed in the long term performance article on the Intel X25-M, running a benchmark that spans the entire drive will often help correct any performance slow downs.  You can see here after running only a pair of HDTach “full” benchmarks the Summit has stabilized at 180/180 MB/s or so.

Here is the HDTach “long” result after equalization

Immediately following the “full” runs, this was the stabilized performance with an HDTach “long” benchmark, the one use for our standard review data.  178/149 is still not as fast as our “fresh” results of 208/172 but it is still impressive.

As I said, we are still doing on-going testing with the OCZ Summit 250GB SSD and will have more details for you soon on this and other drives on the market.
