First of all it is great Verarschung sell a SSD with an effective size of only 32GB as 64GB SSD, although actually 64GB were installed to improve any hits or anything else, or to accelerate. Other SSDs do similar things and give nevertheless only the usable size. And beyond the cache function is not working correctly and destroyed like to seemingly random data on the hard drive. I purchased this product because of many good reviews from various computer magazines. Their tests were all unfortunately probably not extensively enough ... After installing the Caching works really super to then sometime after restarting any files no longer look the way they should look. It is a scandal that such a thing may be sold. OCZ should start a recall ...
