SSD 128 seems poor performance

Yes, this is a low-end drive. My OCZ Onyx 32 GB was also a low-end drive on its days. But the Sandisk SSD is newer, so it should be at least as fast as my old Onyx.

I know that benchmarking shows faster results for the Sandisk SSD compared to the Onyx. It just does not feel faster.

And still no one could tell me why sometimes deleting lots of small files is very slow compared to my 500 GB Samsung HDD.

As an owner of several other great Sandisk products, I am just a little disappointed.
