StorageReview reviewed the successor to the popular Momentus XT, which combined a 500 GB laptop hard drive with a 4 GB flash buffer and gave a nice performance boost at a minimal price premium. The new 750 GB model has 8 GB of flash and better firmware, which results in a significant performance gain over any other non-SSD laptop hard drive on the market.
To be clear, it’s still nowhere near SSD performance in the most important real-world tests (small random reads and writes), but it’s a major improvement over plain hard drives.
If you need a laptop drive with a lot of space and can’t justify (or can’t find) a large enough SSD, keep an eye on this one’s pricing when it launches. It will supposedly list at $245, which is about double the price of the “plain” Momentus 7200. That premium may not be worthwhile yet, but I bet this drive will be a great deal in a few months.
