Chart Edit

Quite Fast Maximum Turbo Frequency

Across all the many processor core personal computers that have been on the market for more than two years the maximum turbo frequencies range from 2.5GHz to 4GHz. At 3.9 gigahertz, the HP Z420 has a quite fast maximum turbo frequency compared to most of the other many processor core personal computers that were released more than two years ago.

Chart Edit

Has One Memory Slot

The number of memory slots found on the HP Z420 is more than most PCs that have been around for more than two years. The most frequently found memory slot is 4x DIMM, but this memory slot is not found on this desktop computer. The memory slots 8x DIMM are also found on this computer.

5 Reasons Against

Quite Small Total Storage Capacity

The average total storage capacity of computers that have been available for a similar time to the Z420 is 800GB, and the total storage capacity range from 180GB to 8.3TB. With a total storage capacity of only 240 gigabytes, the HP Z420 has a very small total storage capacity compared to most of the other desktop computers of a comparable age and spec to the Z420.

If this computer total storage capacity is not big enough for you then you might want to consider the HP Z640 (256GB).
