Samsung introduces SpinPoint F4
 

Samsung has announced its new SpinPoint range, the F4. Available at one single capacity (320 GB) but with either 8 or 16 MB of cache, the SpinPoint F4 features a single 640 GB platter used on just one side and therefore with just one read head.

Samsung is highlighting the reliability of this very simple design as well as improved sequential read and write performance (+10%) due to the higher density. It remains to be seen when higher capacity versions will be launched!
