Looking deeper into the HP Z620's technical specifications show some impressive hardware and support, including its compatibility for both Intel Xeon processor E5-2600 v2 and E5-1600 v2 families for a grand total of 27 different processors. Additionally, it also supports up to 192GB of the latest generation of system memory with 12 DIMM slots as well as integrated 1866MHz DDR3 memory subsystem, allowing the Z620 to be optimized for a 64-bit environment. As far as its power consumption goes, the new HP workstation uses and leverages an 800W 90% efficient power supply, which is ideal for high-end graphics cards if users choose to go that route. The HP Z620 also comes standard with 4x USB 3.0 ports as well as a 1-port Thunderbolt 2 and an HP IEEE 1394b FireWire PCIe cards. Users can also customize their HP Z620 Workstation with multiple different SATA and SAS RAID configuration options that support a variety of high-performance, high capacity storage solutions.

Perhaps the most impressive configurable storage option available with this HP Workstation is the option for HP Z Turbo Drives (256GB and 512GB capacities), as they add a ton of flexibility and power to the Z620. These PCIe drives offer up to twice the performance of standard high-performance SSDs, all at a similar price tag. The HP drives are based on the Samsung XP941 platform which offers peak sequential read throughput of up to 1170MB/s and writes up to 930MB/s.
