Product Information

Forged Aluminum Chassis:The aluminium chassis helps dissipate heat for efficient use without overheating risks. The specifications of the testbed are summarized in the table below: AnandTech DAS Testbed Configuration

On a positive note, the drive comes with two 9-inch cables: USB-C-to-USB-C and USB-C-to-USB-A. That's better than an awkward converter dongle. The Samsung T7 weighs only 58 grams, whereas the SanDisk Extreme Pro weighs much more – 78 grams. These 20 grams of difference can help you make the decision easier if weight is an important factor to you.

It is good to know that 500 MB/s is considered to be a good read speed for an average SSD. Then we can see how fast both of these models are when compared to other SSDs on the market. However, in this particular comparison, SanDisk is superior. The Extreme Pro Portable SSD V2 is claimed to be capable of surviving a drop from 2m and it’s IP55 water and dust resistant, which is great news if you spill a mug of tea on your desk or you’re working in a harsh environment. I found no reason to doubt the claims. Further reassurance comes from the 5-year warranty.

Editor’s Note, August 17, 2023: As recently reported in Ars Technica , a critical mass of users on SanDisk’s forums and Reddit have reported failures of some SanDisk Extreme, Extreme Pro, Extreme V2, and Extreme Pro V2 SSDs, resulting in data loss, as well as the drives becoming unreadable/unmountable. In May, parent company WD released firmware updates for the 4TB SanDisk Extreme, as well as the 4TB, 2TB, and 1TB Extreme Pro models, plus the 4TB Western Digital My Passport, but complaints continue. We are doing our own stress-testing of the sample drives we originally reviewed. As of today, however, we no longer recommend buying any of the aforementioned SSDs, until we are satisfied the issue has been resolved. ( A class-action suit has been levied against WD surrounding issues with these drives.) We have left our original review in place here for reference.]RoHS stands for Restriction of Hazardous Substances or EU’s Directive 2002/95/EC. The aim is to find whether electronic devices have hazardous metals in them. nofanneeded said:Because all portable SSD are a box with internal off the shelves NVME SSD .. I am 100% sure you will find the same Version of SANDISK Extreme Pro as a stand alone NVME ... A RoHS-compliant device means it is tested for hazardous substances and is hazard-free. The Samsung T7 is compliant with RoHS, whereas there is no information on whether SanDisk Extreme Pro is compliant or not.
