As well as offering a mobile store for images or video, the Extreme Pro Portable SSD V2 can be used as a working drive while editing video and, with the right computer, you can expect stutter-free editing and viewing.
This is WD's latest version of its popular MyPassport SSD, not to be confused with the previous incarnation which is still on sale. The new version has a smoother, more rounded design, but while it looks different, it still goes by the exact same My Passport SSD name, just for that little extra confusion. 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 From SanDisk, the brand professional photographers worldwide trust to handle their best shots and footage. 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. ;) Let’s conclude this Samsung T7 vs Sandisk Extreme Pro comparison by pointing out their most significant features.

Forged Aluminum Chassis:The aluminium chassis helps dissipate heat for efficient use without overheating risks.
Direct-attached storage devices (including portable SSDs) are evaluated using the Quartz Canyon NUC (essentially, the Xeon / ECC version of the Ghost Canyon NUC) configured with 2x 16GB DDR4-2667 ECC SODIMMs and a PCIe 3.0 x4 NVMe SSD - the IM2P33E8 1TB from ADATA.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.) SLC or Single Level Cell cache is stored in the TLC NAND Flash. The Samsung T7 comes with the TurboWrite SLC cache acceleration technology. The SanDisk Extreme Pro doesn’t have an SLC cache. Therefore, the Samsung model wins this segment. We have identified a firmware issue that can cause SanDisk Extreme Portable SSD V2, SanDisk Extreme Pro Portable SSD V2, and WD My Passport SSD products to unexpectedly disconnect from a computer. The SanDisk Extreme Pro portable SSD leverages our lightning-fast in house NVMe technology to dramatically increase transfer speeds to up to 1000MB/s and fully saturate the USB 3.1 Gen 2 interface. 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.
High-Speed Data Transfer:The SanDisk 4TB SSD boasts a rapid transfer rate of 2000 MB/s, perfect for handling large 4K video files. SanDisk is also a large company that specializes in storage devices. They produce memory cards, SSDs, USB flash drives, etc. They have a huge variety of SSDs. Features The testbed hardware is only one segment of the evaluation. Over the last few years, the typical direct-attached storage workloads for memory cards have also evolved. High bit-rate 4K videos at 60fps have become quite common, and 8K videos are starting to make an appearance. Game install sizes have also grown steadily even in portable game consoles, thanks to high resolution textures and artwork. Keeping these in mind, our evaluation scheme for direct-attached storage devices involves multiple workloads which are described in detail in the corresponding sections. The chassis of the Extreme Pro Portable SSD V2 is made from forged aluminium to make it very strong but lightweight. And at just 10.22x57.34x110.26mm, it’s small enough to slip into a camera bag unnoticed. The Samsung T7 model comes with a 3-year limited warranty. The SanDisk Extreme Pro comes with a longer warranty period of five years. In this case, the SanDisk warranty is rather generous for today’s terms.TB3 is more popular then USB 3.2 2x2 which is impossible to find in notebook and very rare in Desktops. Write speed is just as important as reading speed. It basically measures how fast one file can be written on the device. Of course, SSDs are far better than HDDs in this segment. On average, HDDs can reach read and write speeds from 80 to 160 MB/s. SSDs are far superior.
CrystalDiskMark gets things off to a good start with stunning peak sequential read/write speeds of 1440/726MB/s respectively, though this is some way short of OWC's claim of "up to 2800MB/s". Real world file transfers will always be slower than a synthetic benchmark test, but we still recorded a hugely impressive 995MB/s peak read speed when shifting one massive video file, though this figure did drop as the transfer progressed, leaving the final averaged video read speed at a more modest - though still very rapid - 645MB/s. An average 612MB/s read speed moving multiple image files is also superb, though write speeds take a significant performance hit, with an average 481MB/s when writing video and just 278MB/s when writing multiple images. That image write rate did peak at a healthier 413MB/s during the transfer, but the drive couldn't sustain this speed, hence the slower average figure.
Upgrade your game with super-fast SSD performance that lasts.
If a device has smaller dimensions, as a rule of thumb, it weighs less. This is true in our Samsung T7 vs SanDisk Extreme Pro comparison. The Samsung T7 weighs only 58 grams, whereas the SanDisk Extreme Pro weighs much more – 78 grams. These 20 grams of difference can help you make the decision easier if weight is an important factor to you. The Samsung T7 can reach a write speed of 1,000 MB/s, almost ten times faster than an average HDD. But, the SanDisk Extreme Pro is far better. It can reach double the speed of the Samsung T7. Its maximum write speed is 2,000 MB/s, and it is a clear winner in this segment. So it'd better have plenty of performance to compensate. Thankfully, with NVMe SSD technology and a Thunderbolt 3 connection promising a theoretical 40Gbps bandwidth (that's 4x faster than USB 3.1 Gen 2), the Envoy Pro EX has all the right ingredients for winning performance.
