6 Reasons For
16% faster processor clock speed Edit
The Fujitsu P420 E85+ is a 3.2GHz processor clock speed PC. That's 0.5GHz faster than the Fujitsu D556 (3.2GHz). Read more

The speed that the microprocessor executes each instruction or each vibration of the clock. The CPU requires a fixed number of clock ticks, or cycles, to execute each instruction. The faster the clocks rate, the faster the CPU, or the faster it can execute instructions. Clock Speeds are usually determined in MHz, 1 MHz representing 1 million cycles per second, or in GHz, 1 GHz representing 1 thousand million cycles per second. The higher the CPU speed, the better a computer will perform.

A higher processor clock speed means that the computer can complete more calculations every second which means that applications will run faster.

Faster maximum turbo frequency Edit
The Fujitsu P420 E85+ is a 3.4GHz maximum turbo frequency PC. That's 0.1GHz faster than the Fujitsu D556 (3.4GHz). Read more

A drive bay is a standard-area for adding hardware to a computer. Most drive bays are fixed to the inside of a case, but some can be removed. A 5.25" drive bay, also known as full-height bays, were found in old PCs in the early to mid-1980s. They were 3 high by 5 wide, and up to 8 deep (83 146 200 mm), used mainly for hard disks and floppy disk drives.

One more 3.5" bay Edit
The Fujitsu P420 E85+ has three 3.5" bays, however the Fujitsu D556 only has two 3.5" bays. Read more

A drive bay is a standard-area for adding hardware to a computer. Most drive bays are fixed to the inside of a case, but some can be removed. A 3.5" drive bay is for floppy disks.
