Two alternatives – X500 and NotePAC-III

If you need a portable laptop-style computer with an expansion slot or two, there are not many options…. There’s the Portexa NotePAC-PRO and the Getac X500 Server. In this article, we will look at the similarities, differences, and suggested applications. Disclaimer – we cannot sell Getac X500’s – but this will attempt to be fair and unbiased. Members of our staff have extensive experience using and modifying the Getac X500 and have a healthy respect for it.


Both systems are large portable laptops.

The X500 (Launched June 2011) is 16.1″ x 12.6″ x 4.6″ (933.2 cubic inches) and the NotePAC-III-PRO-V (Launched February 2019) is 16.75″ x 12″ x 4.5″ (904.5 cubic inches).

The NotePAC of course does feature a triple display monitor, so it’s not quite apples to apples.

The NotePAC-PRO has two PCIe expansion slots as standard, whereas the X500 is expandable using a ‘slice’ that replaces the bottom cover (the dimensions listed include the slice). The X500 slice can be PCI or PCIe, so if you need to support a legacy PCI card then the X500 is the one to choose.

Typical configurations of the NotePAC are considerably more powerful than the X500 and include an Nvidia Quadro RTX4000 graphics card in one of the PCIe slots.

Quad LAN with Intel® Ethernet Controller I350-AM4 (RJ45)

Removable drives

X500 – 2 Drives (six if no PCIe expansion needed)

NotePAC – 4 Drives


X500 – 15.6” (1920 x 1080) 


NotePAC – 3 x 17.1” for (5760 x 1080)


X500 – Intel HD 630 or NVIDIA Quadro P2000


NotePAC –  Aspeed AST2500 or NVIDIA Quadro RTX4000

“A major advantage of the NotePAC is the 144Hz refresh rate on all displays as standard which allows the use of 3D imaging for various uses including targeting”

The MilPAC-RHD16 is a powerhouse of a portable server.  With 16 removable drive bays in four caddies, it can be configured with multiple drive-sets for different security levels.  Performance from the Dual Xeon motherboard, paired to a high powered RAID controller is unmatched by any other portable.

Available with 1GbE, 10GbE, and 20GbE capture cards, it is capable of sustained, multi-gigabit per second recording of network traffic without packet drops.  This system is used to capture entire military combat networks for post-maneuver review and analysis.

Drives, CPU performance/core count, O/S and memory are all configurable. The current maximum space is 16 x 7.6TB removable SSDs + a removable boot drive.  There are 15TB SSD’s hitting the market this year, and the MilPAC will support those from launch.

Now available in a “narrow” version that is small enough to fit in between 19″ rack rails.  This allows deployment in server rooms when space is at a premium.  The portable design means the equipment can be used in environments that may traditionally require an extensive certification procedure.

For desert environments, a version of the MilPAC-III desert filter back is available to special order.

The three-screenMilPAC is also available for C4ISR, CIC and Geospatial applications.
