The ADATA SE730H is another competitor that perhaps deserves more recognition. It is smaller than the SanDisk Extreme Portable, slight cheaper, and sports an IP68 rating making it far more resilient. Like the Extreme, it has a Type-C connector, a three-year warranty and uses 3D NAND Flash technology – but it is slightly slower and comes from a lesser-known brand. Creative professionals know the value of storage space. With capacities of up to 2TB, 5 you’ll have enough room for the files you need to work on or deliver.

SanDisk Extreme Pro leverages our lightning-fast in-house NVMe technology to dramatically increase transfer speeds to up to 1050 MB/s 6 and fully saturate the USB 3.1 Gen 2 interface. 6 So you’ll be able to edit right from the drive – providing full-frame editing with little interruption while saving you time and keeping your computer’s internal storage free. 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. 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.

As compared to 7200 RPM SATA 2 hard drive. Based on published specifications and internal benchmarking tests. 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.
