That disqualifies the likes of the popular Samsung T7 Touch which is not waterproof. 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. 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. Multiple DITs/Loaders/ACs on both coasts have experienced the exact same failure with these drives over the last month.The symptom seems to be that after a sustained write they will completely lose their filesystem and it's a total crap shoot [whether] you can recover it or not. The primary way you will see this is that the drive will unmount and you will not be able to get it to mount again, despite showing up in Disk Utility. You can sometimes recover it using DiskDrill's filesystem rebuild, but occasionally that does nothing. It persists with any filesystem type.

Get fast NVMe™ solid state performance featuring 1050MB/s 2 read and 1000MB/s 2 write speeds in a portable, high-capacity drive that’s perfect for creating amazing content or capturing incredible footage. We devote hundreds of hours of rigorous testing to help make sure your drive is worthy of your best work — and so you know your precious files are in good hands.Ruggedized design with a forged aluminum body to protect the SSD core and dissipate heat. Plus, a durable silicon rubber coating seeks to deliver higher impact resistance with its IP55 rating for water and dust resistance. 1

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.Neither the name of the University of California, Berkeley nor the names of its contributors may be used to endorse or promote products derived from this software without specific prior written permission. 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. 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. Save time storing and transferring data with the forged aluminum chassis that also acts as a heatsink to deliver higher sustained speeds.
