Product Information

Since 1982, PCMag has tested and rated thousands of products to help you make better buying decisions. See how we test. NVMe™ solid state performance with 2,000MB/s 2 read write speeds in a portable drive that’s never not fast 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.

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

The evaluation routine for direct-attached storage devices – portable SSDs, storage bridges (including RAID enclosures), and memory cards – all utilize the same testbed and have similar workloads with slight tweaks based on the end market for the product. Our testbeds have kept pace with the introduction of new external interfaces - Thunderbolt 2, Thunderbolt 3, and USB 3.2 Gen 2 via Type-C. In mid-2014, we prepared a custom desktop based on Haswell, which was then upgraded to Skylake in early 2016. A botched Thunderbolt 3 firmware upgrade on the Skylake machine meant that we had to shift to the Hades Canyon NUC starting in early 2019. This year, we have adopted the Quartz Canyon NUC (essentially, the Xeon / ECC version of the Ghost Canyon NUC) along with build components from ADATA Industrial - 2x 16GB DDR4-3200 ECC SODIMMs and a PCIe 3.0 x4 NVMe SSD - the IM2P33E8 1TB.As for IOPS - what is the point of testing the device outside of its designed enclosure if it is forever going to be used in the enclosure? I can test portable SSDs' IOPS perfectly fine as they come. They are not going to be used as internal SSDs, only as portables. So, comparing the performance without the bridge chip they come with is irrelevant. And again, I've already reviewed the internal devices as linked above. ;) The table below presents a comparative view of the specifications of the two portable SSDs covered in this review. Comparative Portable SSDs Configuration With the USB 20 Gbps link, the drive even outperformed the Thunderbolt 3 competition under various workloads Get peace of mind when you’re out in the world thanks to a 5-year limited warranty 3 and a forged aluminum chassis-silicon shell combo that offers a premium feel and added protection. Since 2004, I have worked on PCMag’s hardware team, covering at various times printers, scanners, projectors, storage, and monitors. I currently focus my testing efforts on 3D printers, pro and productivity displays, and drives and SSDs of all sorts.

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. That speed comes at a hefty cost, though. At almost twice the price of a portable USB 10Gbps SSD and just a few dollars shy of higher-performing Thunderbolt 3 SSDs, the Extreme Pro v2 is only worth the cash for those who can fully leverage its capabilities. Thunderbolt 3 enclosures round up ... with the fastest NVMe SSD (>3000MB/s) inside to see the real potential of the enclosure ..Over the years, I have reviewed iPad and iPhone science apps, plus the occasional camera, laptop, keyboard, and mouse. I've also written a host of articles about astronomy, space science, travel photography, and astrophotography for PCMag and its past and present sibling publications (among them, Mashable and ExtremeTech), as well as for the PCMag Digital Edition. From SanDisk, the brand professional photographers worldwide trust to handle their best shots and footage.
