The solution is build up with two components: a Data logger service and a web application to visualize the data. The whole application is running on a single fanless Alix.1C board. The Alix.1C is not available anymore but the successor Alix.1D is similar. You can get it for instance from NRG - Systems or as a complete bundle at shop.varia-store.com). The board consumes only 4-5 Watt ~ 10 Euro per year. Windows XP Professional is installed on a 4GB Sandisk Extreme III CF card. Total hardware costs is about 152 Euros, XP Pro can be bought for about 30-40 Euros already.
Alternativly it is of course possible to use an (old) existing Notebook or an home server. Some users are already doing it.

Phison Ps2251-70 [top] -

This article explores the architecture, market impact, and lasting legacy of the Phison PS2251-70, explaining why this tiny piece of silicon remains a topic of discussion for data recovery specialists and electronics enthusiasts today. To understand the significance of the PS2251-70, one must first understand the role of a flash controller. A USB drive consists of two primary elements: the NAND Flash memory (where the data is actually stored) and the controller (the processor that manages that data).

If you purchased a generic, no-name USB 3.0 drive between 2013 and 2017 that performed surprisingly well, there is a high probability it was powered by the PS2251-70. It effectively democratized USB 3.0 speeds, ensuring that faster data transfer wasn't exclusive to premium phison ps2251-70

The controller is the "brain." It handles error correction (ECC), wear leveling (ensuring data is written evenly across memory cells to prevent burnout), bad block management, and the translation of data between the computer’s operating system and the raw NAND memory. This article explores the architecture, market impact, and

Among the most ubiquitous and influential controllers in the history of USB mass storage is the (often abbreviated as the PS2251-70 or simply the "70" series). This single chip powered millions of USB 3.0 flash drives throughout the early 2010s, bridging the gap between the aging USB 2.0 standard and the modern high-speed era. If you purchased a generic, no-name USB 3

In the world of consumer electronics, the components that make the biggest difference are often the ones users never see. When you plug a USB flash drive into your computer, you likely only concern yourself with two things: capacity and speed. However, the component dictating both of those factors—and the longevity of your data—is the flash controller chip.

When the Phison PS2251-70 hit the market, it enabled a new generation of "high-performance" flash drives. Because Phison offered the controller at a highly competitive price point, it became the go-to choice for Tier-2 and Tier-3 manufacturers, as well as major brands looking to build "value" high-speed drives.
