Workstations Are designed to perform more faithfully than a normal PC with CPU’s and memory which feature error correcting code, high performance graphics cards, and ISV certification that ensures the top software programs have been rigorously tested to operate reliably. The Z420 is a solid workstation that performs quite well at an affordable price.

Small review of HP Z420 Workstation:

The HP Z420 workstation is a mid-range single socket workstation and features ISV certification for software in information analysis, CAD, 3d animation, and gas and oil mining, to name a few. This system features the reliability and enterprise functionality you would expect from HP.

Speaking of storage, HP opts for a 256GB Micron C400 solid-state drive as the primary storage drive along with a 1TB, 7,200-rpm Seagate Barracuda as a secondary “scratch” disk drive. This is not an uncommon arrangement in lower-end workstations, but people mindful of application-specific functionality may want to invest in a secondary SSD for accurate scratch data performance, which could involve high-speed throughput for real-time job rendering–throughput beyond what a SATA hard drive could deliver.

We are slightly surprised that HP opted to get a consumer-class Barracuda driveway as opposed to an enterprise-class alternative. Like all consumer hard drives, the Barracuda is designed for occasional operation through an 8×5 responsibility cycle. Push it much beyond that and the odds of premature failure increase. For just another $40 or so, an equivalent enterprise-class drive, for example Seagate’s Constellation CS, could be built for performance round the clock.

Those needing to custom order a Z420 from HP’s site can elect for unspecified 10,000-rpm SATA or SAS drives, which will be enterprise-grade, even though the latter will also require the purchase of an LSI SAS controller for $150. All that said, we’re conscious of the need to maintain sticker prices fair to attract buyers.

All memory alternatives for the Z420 use ECC unbuffered modules. HP’s motherboard packs gobs of internal USB and SATA dash and utilizes Intel’s popular C602 chipset.

Processor options extend up to the Xeon E5-2687W (eight-core, 3.1GHz), also note that HP builds in an Infineon TPM 1.2 chip for extra safety performance. The adventurous can opt for Windows 8, however, our config came with 64-bit Windows 7 Professional.

The Keep in mind, the CPU will determine the rate in which the memory is clocked. To attain memory speeds of 1866MHz requires both processor and memory to support this speed. Memory rate will default to the slowest performer between memory modules and CPUs.

Up To four drives total can be set up on the machine with the fourth driveway occupying the top 5.25-inch press bay and will require an external bay adapter to encourage an HDD. There is also a removable boot drive option and support for optional PCIe Solid State Drives with up to 512GB using a HP Z Turbo Drive SSD. You’ve got options for hard drive controls starting with the integrated SATA 6.0 Gb/s Controller along with mill incorporated RAID on the motherboard to get SATA drives. For RAID support on Linux programs all drives must be identical in form and capacity. PCIe SSDs cannot be used at a boot RAID configuration.

The Intel C622 chipset supports one processor. Users can choose from several Xeon E5-1600 or E5-1600 v2 processors with up to eight cores or just two E5-2600 v2 chips including a workstation specific CPU that supports eight cores. Transfer speeds are 1866MT/s, 1600MT/s or 1066MT/s.


Despite being a bit out of its natural element in our standard tests, it’s clear that the Z420 is no slouch. The machine brings its powerful weight with speed and grace suitable for its own sub-$2,000 price point.

As we mentioned initially, you can get an equivalent consumer system for less, even though HP arguably indulges in a tiny cost-cutting with the Barracuda hard drive. But we haven’t any complaints in the CPU, GPU, or even memory sections, and HP’s tower case, which can be adapted for rackmounting, is completely suited to demanding corporate environments–given there is little or no dust, because HP’s layout does not have any filters.

The Z420 is priced fairly for its level of validation and support HP pours into its offering, and this is where the machine makes sense: moderate-demand visual computing to get a non- to moderate-range budget. If you’re really serious about graphics performance, look higher up HP’s heap to the Z620 or even Z820. But if you are searching for dependability and service backed by adequate velocity, then the Z420 is a great fit.
