SanDisk Extreme PRO and Crucial X6 4TB Portable SSDs Review

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.] Whether you’re trekking through snowy mountains or filming in the middle of the desert, this drive won’t let you down.USB 3.2 Gen 1 (a.k.a. the old USB 3.0), typically good enough a ceiling for older external SSDs with SATA-based silicon, caps read and write speeds for external SSDs at about 550MBps and 500MBps respectively. While you can use the Extreme Pro V2 drive with any of these interfaces, buying it without provision for a Gen 2x2 interface would be like buying a Corvette for runs to the grocery store. Also, that enclosure is made with an older Alpine Ridge TB3 controller, not titan ridge or newer like on some of these portable SSDs. So, its older tech. Save time storing and transferring data with the forged aluminum chassis that also acts as a heatsink to deliver higher sustained speeds.

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. 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. Some unconfirmed chatter suggests that the SanDisk Extreme SSD issues affect only those using devices "manufactured after November 2022." Still, at the time of writing, we would advise anyone using these drives to use them with extreme caution. Perhaps it is advisable to only use these storage devices for convenient duplicate or temporary data until the fix arrives and it has been tested well.
