Sabrent Rocket NVME SSD inside One-Netbook A1

Sabrent Rocket is one of the fastest NVME SSD series in the formfactor of M.2 2242. According to the manufacturer, "its speed performance can reach up to 2500MB/s read and 2100MB/s write" (ref).
Here is what you can expect from this SSD inserted into the One-Netbook A1 handheld computer:

It’s worth mentioning that the default One-Netbook SSD shows very similar performance.

So there is no reason to replace SSD in order to get higher speed. The default SSD is pretty much the best you can achieve.

Gentoo on a One-Netbook A1

I’m glad to present you the new manual: Gentoo on a One-Netbook A1. This manual is intended to help user to configure Gentoo distribution of the GNU/Linux operating system for One-Netbook A1 handheld computer. Despite the fact that the manufacturer claims Linux support on the product description page, to my knowledge there is no Linux distribution, which actually supports the device out of the box. Therefore I hope that this manual will be useful for some A1 owners.

I would also like to note that there are several other Gentoo manuals available for different handheld computer:

Handhelds in use

I am pleased to present to you a new gallery dedicated to the use of handheld computers in various places. Typically these images are shot in haste, so don’t expect high quality.

Let’s compare the size of One-Netbook OneGx1 Pro and other UMPCs

Meet the One-Netbook A1

One-Netbook A1 is based on 2 year old Core m3-8100Y. However, it’s still quite a remarkable device. It’s the first UMPC of the second epoch with a swivel hinge.

Comparison with Fujitsu Lifebook U820 suggests itself.

Benchmarking OneGx1 Pro with eGPU

I connected EVGA GeForce GTX 1080 FOUNDERS EDITION to One-Netbook OneGx1 Pro via the following eGPU box: Sonnet eGFX Breakaway Box 550.

Here are the main results:

eGPU can improve 3D performance of OneGx1 Pro by at least 4 times.
Performance of the video card inserted in the desktop is significantly higher than performance of the same card connected via eGPU box.
Performance of eGPU is significantly higher when the image is displayed on an external monitor.

More benchmarks of OneGx1 Pro are availavle here.

Let’s take another look at One-Netbook OneGx1 Pro. But this time in low light conditions.

Benchmarking OneGx1 Pro

Here are few benchmark results of the One-Netbook OneGx1 Pro.
I was quite surprised, that this handheld is faster than Core i7-4790k.
The graphics processing unit is almost 6 times faster than UHD 615 (Amber Lake m3).

Behold the world’s most powerful handheld

One-Netbook OneGx1 Pro is not only the most powerful handheld computer in the world as of today (January of 2021). It’s also one of the most beautiful handhelds I’ve ever seen.

The device is based on Intel® Core™ i7-1160G7. P

EDIT: Readers asked why I consider OneGx1 Pro the most powerful handheld, not GPD Win3. Let me explain. According to the Indiegogo, Win3 is still a prototype and estimated shipping is "May 2021". So it’s not out for retail yet, but OneGx1 is already available for purchase.
