SanDisk 2TB Extreme Portable SSD, USB-C USB 3.2 Gen 2, External NVMe Solid State Drive, up to 1050 MB/s, IP65 rated for dust and water resistance

Product Information

USB3.2(Gen2)/3.1(Gen1)/3.0/2.0端子搭載のWindows(10/8.1/7)、MacOS(11/10.14~10.16)、PlayStation(R)5、PlayStation(R)4 SanDisk’s Extreme v2 is a bit bigger than the original, measuring 101 x 52 x 9 mm and weighing in at under 63 grams. 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. Uiflorin said:Now, to answer your question, powering up the drive containing that memory does not refresh it's content. 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.

It is worth noting that if you use a data recovery service, you will not void an otherwise valid limited warranty as long as you get a written verification from the service provider.

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

L'ho provato sia su Windows sia su MacOS, con partizioni cryptate o no. Nel mio caso il collo di bottiglia è evidentemente le porte USB obsolete. MIL-STD-810G 516.6 procedure IV」に準拠しています。万が一の落下による衝撃から保存されたデータをしっかり守ります。また記憶媒体にフラッシュメモリーを採用。可動部分を排除することにより不意の落下や、携帯時の振動など様々な衝撃からデータをしっかりガードします。 Ars Technica's Lee Hutchinson confirmed suffering not one, but two 2TB Extreme Pros dying. After filling about halfway, each drive met a slew of read and write errors. When he disconnected and reconnected the SSD, it showed it was unformatted with the drive completely wiped, including its file system. Wiping and reformatting didn't help, and this happened with two different units. 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.
