Samsung SpinPoint M7: HM500JI – 500 GB
This HDD from Samsung is well known to us. It is the 500GB model from the SpinPoint M7 series. Of course, it is not new, yet still available and suitable for our purposes as a reference point in comparison with newer products.
Samsung SpinPoint M7E: HM641JI – 640 GB
And here comes one of the new drives. Samsung did not introduce a whole new series to mark the transition to 320GB platters. Instead, the company just spun off the M7E subseries our 640GB model belongs to. It has as much cache memory as its predecessors – 8 megabytes.
By the way, Samsung has announced a highly interesting SpinPoint MP4 series that has 320GB platters rotating at 7200 RPM and 16 megabytes of cache. Unfortunately, we have not yet managed to get an MP4 drive for our tests.
