Synthetic Benchmarks: CDM, ATTO & Blackmagic
CrystalDiskMark



Sequential results here look great with more than 1GB/s for both reads and writes. 4K QD1 random reads look excellent as well.
ATTO



ATTO verifies our test subject as capable of delivering essentially full sequential throughput at 128K transfers at the standard test queue depth of 4. This is exactly what we are looking for from any SSD, internal or portable. Impressive.
Blackmagic



Is it suitable for use as a portable scratch disk for video? BlackMagic says it can get the job done. Outstanding.
Real-World Testing: PCMark 10, 3DMark SSD Gaming & Transfer Rates
PCMark 10 Data Drive Benchmark
The Data Drive Benchmark is designed to test drives that are used for storing files rather than applications. You can also use this test with NAS drives, USB sticks, memory cards, and other external storage devices.
The Data Drive Benchmark uses 3 traces, running 3 passes with each trace as follows:
- Copying 339 JPEG files, 2.37 GB in total,?into?the target drive (write test).
- Making a copy of the JPEG files (read-write test).
- Copying the JPEG files to another drive (read test).


This test involves a good amount of random data and as such it can be overwhelming for many SSDs in our test subjects' class, but not for our 2TB Ultra Compact SSD. Impressive.
3DMark SSD Gaming Test
UL's newest 3DMark SSD Gaming Test is the most comprehensive SSD gaming test ever devised. We consider it superior to testing against games themselves because, as a trace, it is much more consistent than variations that will occur between runs on the actual game itself. This test is, in fact, the same as running the actual game, just without the inconsistencies inherent to application testing. In short, we believe that this is the world's best way to test an SSDs gaming prowess and accurately compare it against competing SSDs. The 3DMark SSD Gaming Test measures and scores the following:
- Loading Battlefield V from launch to the main menu.
- Loading Call of Duty Black Ops 4 from launch to the main menu.
- Loading Overwatch from launch to the main menu.
- Recording a 1080p gameplay video at 60 FPS with OBS (Open Broadcaster Software) while playing Overwatch.
- Installing The Outer Worlds from the Epic Games Launcher.
- Saving game progress in The Outer Worlds.
- Copying the Steam folder for Counter-Strike Global Offensive from an external SSD to the system drive.


Gaming is a performance metric that matters to most DIY consumers, especially to the enthusiast crowd that TweakTown caters to. We are now including gaming performance as a part of our external SSD reviews, as using portable storage for gaming duties is very popular among avid gamers. Ultra-portable, fully compatible storage is a nice complement to any console or PC gaming device.
Here again, this test can be overwhelming for ultra-compact SSDs, but again our test subject performs admirably.
DiskBench - Transfer Rates




We brutalize our test subjects with our extremely hard-to-swallow 100GB data block. This data block is the same one we use for our internal SSD testing and comprises more than 62K files. 100GB is probably right at the upper limit for a single transfer, so as we see it, this is a much more realistic test scenario than a sustained filling of the entire drive.
Surprisingly robust results here for an ultra-pocket-friendly storage device, especially when programming data.
Final Thoughts

It's fast, rugged, dustproof, water resistant, and supremely pocket-friendly, making it a must-have for everyday mass data on the go. Don't leave home without it; I don't. Editor's Choice.
