SanDisk Extreme® Portable SSD V2 USB-C, USB 3.2 External

Whether you’re trekking through snowy mountains or filming in the middle of the desert, this drive won’t let you down.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. Up to three-meter drop protection and IP65 water and dust resistance 5 mean this durable drive can take a beating. 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 ...

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.] The specifications of the testbed are summarized in the table below: AnandTech DAS Testbed Configuration

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.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. WD's flagships and Crucial's mainstream X6 offerings represent two ends of the pricing spectrum. At the same capacity point, they present an interesting view of the tradeoffs involved in achieving a particular price point - performance, consistency, BOM features, and value additions. This review looks at the features of the SanDisk Extreme PRO v2 4TB and the Crucial X6 4TB portable SSDs, along with an analysis of their performance numbers and value propositions. Introduction and Product Impressions 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.
