A HDD/SSD utility software which supports a part of USB, Intel RAID and NVMe.

As you can see, the EVLVR SSD runs on a PCIe x2 link instead of the more traditional PCIe x4 link that many NVMe drives use. It shows that the Thunderbolt 3 interface is entirely transparent to the system.

ATTO Disk Benchmark

“As the industry’s leading provider of high-performance storage & network connectivity products, ATTO has created a widely-accepted Disk Benchmark freeware utility to help measure storage system performance. As one of the top tools utilized in the industry, Disk Benchmark identifies performance in hard drives, solid state drives, RAID arrays as well as connections to storage. Top drive manufacturers, like Hitachi, build and test every drive using the ATTO Disk Benchmark”

ATTO Disk Benchmark shows the EVLVR just about hitting the bullseye on the rated 1000MB/s writes but comes in a bit shy of the 1600MB/s read speeds. Other publications have been getting the 1600MB/s speeds pretty reliably so it must be a bottleneck with our Asus ThunderboltEX 3 controller somehow.

CrystalDiskMark 6.0

“CrystalDiskMark is designed to quickly test the performance of your hard drives. Currently, the program allows measuring sequential and random read/write speeds.”

CrystalDiskMark gives us a bit closer to rated sequential read speeds but our TB3 controller seems to still be slightly limiting us.

Anvil’s Storage Utilities

Anvil’s Storage Utilities is a powerful tool that was designed in order to provide you with a simple means of assessing the read and write performance of your Solid State Drive or Hard Disk Drive.

The benchmark tool helps you monitor and check the response time of your unit as well as view the system information collected using Windows Management Instrumentation (WMI).

Anvil’s Storage Utilities has been designed to be the most comprehensive benchmark tool for Solid State Drives on the market. That does not mean that you can’t use it for conventional platter-based drives as well, but you do get the most out of the program when you test the speed and performance of SSDs with it. The program has gone through a series of beta and release candidate builds already and is currently available as Release Candidate 3. It is usually linked from this forum thread, which currently is not the case for the RC build which you can download here directly. You can’t use previous builds as they are set to expire automatically.

You can run a benchmark right away by selecting a drive from the menu at the top right or check out the settings first to make sure everything is configured correctly here. Here you can simulate a compression level of the test file, e.g. database, application or uncompressed, and whether you’d like to use the same test file on consecutive runs or generate a new one every time. As far as benchmarks go, you can run a standard SSD benchmark that is testing read, write, or both performances of the drive, or run threaded IO benchmarks only.

Anvil shows some pretty nice IOPS from a ‘portable’ drive, even if it comes in a little under rated speeds from top to bottom.


The AS SSD benchmark determines the performance of Solid State Drives (SSD). The tool contains six synthetic and three copy tests.

The synthetic tests determine the sequential and random read and write performance of the SSD. These tests are carried out without using the operating system cache. In Seq-test the program measures how long it takes to read a 1 GB file to write respectively. 4K test the read and write performance is determined at random 4K blocks. The 4K-64 corresponds to the test Third 4K procedure except that the read and write operations are distributed to 64 threads. This test should SSDs pose with Native Command Queuing (NCQ), differences between the IDE operation mode where NCQ is not supported, and the AHCI mode. The additional compression test can measure the power of the SSD in response to the compressibility of the data. This is especially for the controllers that use to increase the performance and life of the cell compression, important.

In the first three synthetic tests and the compression test, the size of the test file 1 GB. Finally, the access time of the SSD is calculated, wherein the access to read over the entire capacity of the SSD (Full Stroke) is determined. The write access test, however, is done with a 1 GB big test file.

AS SSD always comes in a little under rated sequential speeds due to its different testing methodology, but this looks about like what we expect.

Our copy tests actually come in quite a bit faster than what we expected them to.

Compression testing also comes in a little faster than we expected. We do see some cache cycling evident on the write tests but we still only dip to around 730MB/s for a split second.


Native M.2 Testing

As the actual storage device is a native M.2 drive, and we seem to be seeing some slight read speed reductions out of our Thunderbolt 3 controller, we decided to test the drive installed in a native motherboard M.2 slot.

Our detected interface still shows the expected PCIe 3.0 x2.

Write speeds go up just a tiny bit, but read speeds jump significantly to nearly 1.75GB/s, quite a bit above the rated read speeds.

CrystalDiskMark actually shows pretty well spot-on with the rated speeds.

AS SSD gets a nice boost in the main test, picking up around 130 points overall and about 200MB/s more on sequential reads.

Copy testing comes in about the same.

Our compression benchmark appears to be quite a bit faster, even in the cache flush dips (with the one quite large dip being an outlier rather than the norm).
