OCZ Vertex 2 SSD Review
If there is one thing we've learnt over our time testing drives here at OC3D it's that the larger the chunk being read or written, the better the performance. Although SSDs suffer far less than mechanical drives there is still a performance drop when dealing with very small data sizes.
HD Tune allows us to test using a few different data sizes and this should help highlight if the Vertex 2 with its SandForce controller manages to smooth this out with its alternative cache methods.
Sure enough the gap between the small 128KB chunk which normally would see a very low score, and the data chunks that are in the megabyte range, is far smaller than we'd expect.
However by far the most noticeable aspect is that the write speeds are consistently faster than the read speeds. Given that reading is exponentially more common than writing, even on an OS drive, this is surprising to say the least. Let's see if this is maintained throughout our testing.
