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. The competitionOverall though, if you discard the far cheaper alternatives from lesser known vendors, there’s little incentive for Sandisk to drop the price of the G-Drive further. That is particularly true given the presence of the speedier and far more expensive G-Drive Pro SSD which carries a 50% premium and a near-200% improvement in speed thanks to its Thunderbolt 3 interface. 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. The Sandisk Professional G-Drive SSD is a prime example of that; this rugged, external storage device still carries a premium on external hard drives but that is shrinking rapidly while other inherent features of SSD technology - speed, reliability, power consumption and size - have been improved. Pricing and availability

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.

Another thing about the flash memory is the indurance of the cell, how many times the memory cell accepts write/erase cycles until it starts to "wear" and not store anymore the information. That number is in the hundreds now days. If you read correctly the specification of an SSD drive, you will find a specification called "TBW", total bytes written. Dividing that number by the capacity of the drives yields the number of erase/write cycles that will wear the cells. Portable SSD woes — SanDisk Extreme SSDs keep abruptly failing—firmware fix for only some promised Ars saw two 2TB units become unreadable, but SanDisk only confirms 4TB troubles.
