There is an Anandtech article that discusses findings that a worn out drive (at the end of its endurance rating) can lose data much faster depending on temperature: https://www.anandtech.com/show/9248/the-truth-about-ssd-data-retention Up to stated speeds. Based on internal testing; performance may be lower depending on host device, interface, usage conditions and other factors. 1MB=1,000,000 bytes. A footnote about the branding. G-Tech (from which G-Drive is derived) started life as part of HGST, which was acquired by Western Digital. G-Tech survived as a rival to Seagate’s LaCie, supplying rugged, external, reliable storage devices and accessories to outdoor enthusiasts, prosumers and professionals. With the recent launch of Sandisk Professional, it is likely that G-Tech and G-Drive will be sunsetted in the near future. Up to three-meter drop protection and IP65 water and dust resistance 5 mean this durable drive can take a beating. We’re looking for 2TB superfast, extremely rugged, IP67+ rated external solid state drives. That disqualifies the likes of the popular Samsung T7 Touch which is not waterproof.

Co BIY said:Interesting. I assumed that "refreshing" the charges/data was one of the routine maintenance tasks of the SSD controller and assumed that it would be done on a routine/scheduled basis. If the data is stable for 10 years then it makes sense that this is not done. I assumed the stable time was a lot less then 10 years.

You can keep it powered up continuously, the information stored in the transistors is NOT UPDATED OR REFRESHED by the power applied to device, unless you write again the information. This principle of refreshing the data from time to time is used in the RAM memory in computers, and losing power leads to losing data. The small and light form factor of the Extreme PRO® SSD means it couldn’t be easier to keep your content with you whether you’re crossing town or traveling to an international location. Interesting.

Hard drives based on magnetic retention of data are better in this respect, since the retention time is greater if the device is kept properly.The Extreme PRO® SSD works with PCs and Mac™ computers right out of the box and connects with USB Type C and Type A, 3 making it easy to start and keep working in almost any situation. The SSD controller and the NAND Flash memory used are unknown; however, we’d assume that it shares some DNA with the SN530, Western Digital’s entry level NVMe platform. Get peace of mind when you’re out in the world thanks to a 5-year limited warranty 3 and a forged aluminum chassis-silicon shell combo that offers a premium feel and added protection.

With a carabiner loop integrated and a durable silicone coating, the Extreme v2 features a functional, portable, and enduring design for those on the move in tough conditions. But unlike the Extreme Pro, the Extreme v2’s case and internal structure is made of plastic rather than rigid aluminum. This makes for a small and compact design that is also pretty light, but a little less resistant to twists and bending.

That is why a worn out SSD drive, that has reached a TBW spec, will not retain the information for long.SanDisk 2TB Extreme Portable SSD - Up to 1050MB/s - USB-C, USB 3.2 Gen 2 - External Solid State Drive - SDSSDE61-2T00-G25 Now, to answer your question, powering up the drive containing that memory does not refresh it's content.
