SanDisk Extreme Pro Portable V2 Portable SSD Review – The Thunderbolt 3 Alternative


Crystal Disk Benchmark is used to measure read and write performance through sampling of random data which is, for the most part, incompressible. Performance is virtually identical, regardless of data sample so we have included only that using random data samples.




The toughest benchmark available for solid state drives is AS SSD as it relies solely on incompressible data samples when testing performance. For the most part, AS SSD tests can be considered the ‘worst case scenario’ in obtaining data transfer speeds and many enthusiasts like AS SSD for their needs. Transfer speeds are displayed on the left with IOPS results on the right.


Anvil’s Storage Utilities (ASU) are the most complete test bed available for the solid state drive today. The benchmark displays test results for, not only throughput but also, IOPS and Disk Access Times. Not only does it have a preset SSD benchmark, but also, it has included such things as endurance testing and threaded I/O read, write and mixed tests, all of which are very simple to understand and use in our benchmark testing.


TxBench is one of our newly discovered benchmarks that we works much the same as Crystal Diskmark, but with several other features.  Advanced load benchmarking can be configured, as well as full drive information and data erasing via secure erase, enhanced secure erase, TRIM and overwriting.  Simply click on the title for a free copy.

  1. Fairly soon you will be reviewing the SanDisk Extreme Pro ‘Super Speedy’ Portable SSD when it comes out with USB4, capable of 40Gb/s. Thankfully we won’t see .1, .2 etc. as they are doing away with the version numbers.
    Also USB4 and Thunderbolt 3 will start to become compatible with each other. A quote:

    “Compatible With Thunderbolt 3 Optionally

    Intel made news when it said it had given the Thunderbolt 3 protocol to USB Promoter Group, allowing devices with USB4 ports to potentially be compatible with Thunderbolt 3 devices and USB4 devices to attach to Thunderbolt 3. That’s good news for everyone, especially laptop users who want to play games by connecting an eGPU (external graphics card).”

    Hopefully connectivity will become much more standardized, but I doubt it.

    SanDisk sure has been busy bringing us new and excellent products. thanks for the review Les.
