Solid state drives have advantages and disadvantages, which the results pretty much illustrate. The game installation test results show that writes on our 60GB SSD were substantially slower than writes on the stock PS3 hard drive by around 20-30 percent. More expensive SSDs have substantially faster write speeds and compete easily with the fastest desktop drives on the market.
The Devil May Cry 4 installation time in particular looks odd. The length of time the game takes to install comes as no surprise, but its performance compared to other games is undeniably subpar. Both Assassin's Creed and Grand Theft Auto IV stay relatively close to each other in terms of transfer rates, while Devil May Cry 4 runs almost half as fast.
Write speeds are only one part of the story because you generally install a game only once. The rest of the time, you'll likely be loading up saved games, waiting for levels to load, or launching games from the XMB. The SSD excels in those instances. Assassin's Creed showed tremendous speed increases both when starting the game and when loading a saved game. Grand Theft Auto IV also had gains, but Devil May Cry 4 hardly budged in favor of the SSD when it came to saved game loads. The SSD's superior read performance doesn't nullify load times entirely, but it does help to reduce them.
