PCW: An SSD can read and write data many times faster than the best mechanical hard drive. On the downside, flash memory is many times more expensive than the innards of a typical hard drive, so manufacturers have limited their SSD capacities to hit reasonable price points: A 128GB SSD costs about $130, and for that same price tag, you can buy a 3.5-inch desktop hard drive that delivers 2TB of storage, or a 2.5-inch laptop drive that provides 1TB of storage.
Seagate FireCuda hybrid drive is similar like normal hard drive but with its SSD cache, it has change the game with faster loading time for frequent accessed file. I put the hybrid drive on a test to see if the cache really works.
