Notebook drive manufacturers can choose between two drive heights: 9.5 mm and 12.5 mm. At 9.5 mm, most drives are limited to two spinning platters, while 12.5 mm has enough room for three, enabling higher capacity. We compare the two 2.5" variants.
The terabyte drive doesn't do particularly well in our application benchmark. Again we can only assume that this type of workload was not considered a primary requirement for the high-cap model, as it does remarkably well on throughput.
