The SanDisk Extreme Pro V2 supports the latest and fastest USB flavor (USB 3.2 Gen 2x2, also called SuperSpeed USB 20Gbps), which offers transfer speeds of up to 2,000MBps for both read and write when connected to a compatible USB-C port. It tested just short of that (1,909MBps read, 1,919MBps write) in our Crystal DiskMark 6.0 sequential read and write testing. Its scores were also a smidge under the speeds we recently saw from the Seagate FireCuda Gaming SSD (1,992MBps read, 1,967MBps write), which supports the same 2x2 interface. (See how we test SSDs.) Get extra peace of mind with a 5-year limited warranty 3 and a durable silicon shell that offers a premium feel and added protection to the drive’s exterior.

The table below presents a comparative view of the specifications of the two portable SSDs covered in this review. Comparative Portable SSDs Configuration 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 ... 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. 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.
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.] There are plenty of external storage solutions out in the market, but very few of them will be as durable as the Extreme Pro Portable SSD. It’s got great transfer speeds to keep you going, plenty of storage, and comes in a variety of storage sizes. 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.

From SanDisk, the brand professional photographers worldwide trust to handle best shots on their toughest assignments. 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. Whether you’re trekking through snowy mountains or filming in the middle of the desert, this drive won’t let you down. In a thread about 4TB Extreme Pro drives in a film and video editors subreddit, a Reddit user called ian__ wrote:Since 1982, PCMag has tested and rated thousands of products to help you make better buying decisions. See how we test. 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 Methodology TB3 is more popular then USB 3.2 2x2 which is impossible to find in notebook and very rare in Desktops. 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.

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 evaluation scheme for DAS units involves multiple workloads which are described in detail in the corresponding sections.Get fast NVMe™ solid state performance featuring 1050MB/s 2 read and 1000MB/s 2 write speeds in a portable, high-capacity drive that’s perfect for creating amazing content or capturing incredible footage. 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. 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. 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. ;) 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. (WD is SanDisk's parent company.)

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. Redistribution and use in source and binary forms, with or without modification, are permitted provided that the following conditions are met: 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.

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.
