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

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. It says my disks are not affected, but just out of curiosity I made up several serial numbers and all of them said it had not been impacted, so I don’t know if the tool is accurate. Up to 2000MB/s read and write speeds. Based on internal testing; performance may be lower depending on host device, interface, usage conditions and other factors. 1MB=1,000,000 bytes.

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. seanwebster said:At that point you wouldn't be testing the actual portable SSDs as they are, you would just be testing the performance of the internal SSDs in that one enclosure. Thus, comparing just the underlying storage alone. You can't compare the performance or thermal characteristics of these portable SSDs without using the default enclosures and bridge chips. 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. https://forums.sandisk.com/t/sandisk-extreme-portable-ssd-v2-sandisk-extreme-pro-portable-ssd-v2-and-wd-my-passport-ssd-external-drive-firmware-update SanDisk provides a generous five-year warranty, which we have also seen on other Western Digital products such as the 2020 version of the My Passport SSD.

SanDisk 4TB Extreme PRO Portable SSD, USB-C USB 3.2 Gen 2x2

nofanneeded said:This is not true , because the internal hardware of TB3 drives tested does not match ... If you want the best out of TB3 , you should get an empty TB3 box and put the best NVME SSD inside it. 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. Prior to looking at the benchmark numbers, power consumption, and thermal solution effectiveness, a description of the testbed setup and evaluation methodology is provided. Testbed Setup and Evaluation MethodologyThe table below presents a comparative view of the specifications of the two portable SSDs covered in this review. Comparative Portable SSDs Configuration The Extreme Pro is IP55 water and dust resistant and rated to withstand a two-meter drop, though we feel that is a very conservative rating. At 85 grams, the Extreme Pro has a solid and weighted feel to it. That, along with the smooth rounded silicone-coated edges, conveys an apple-esque quality. Also you need to tear down the External drives in each review to see which NVME SSD is in there ... it will also help you to determine TBW/IOPS if the external drive does not say just by discovering which NVME SSD they are using inside. The new SanDisk Extreme Pro v2 comes with some changes under the hood, too. A new ASMedia ASM2364 bridge controller communicates with the host at faster speeds because it has twice the PCIe lane count as the ASM2362, which means twice the throughput. Not only does it maintain a speedy 20 Gbps link while connected to a PCIe 3.0 x4 SSD, but it also features link power management to reduce idle power consumption. The controller also supports Trim to keep performance predictable.
