THE SSD REVIEW TESTING PROTOCOL
At The SSD Review, we test our flash drives slightly different depending upon the drive’s marketed purpose, that of a consumer or an enterprise focused drive. For a consumer drive, our goal is to test in a system that has been optimized with our SSD Optimization Guide, however CPU C State alteration may or may not have occurred depending on the motherboard and BIOS configurations. Benchmarks for our consumer tests are that of fresh drives, so that we can verify that the manufacturer’s specifications match the drive. Additionally, we also try to include links to the benchmarks used in our report so that you as the reader can replicate our tests to confirm that your drive is top-notch.
This Test Bench build was the result of some great relationships and purchase; our appreciation goes to the below mentioned manufacturers for their support in our project. All of the components we use for testing and evaluation can be easily purchased at a relatively affordable price. The links provided below can assist in pricing, as well as availability for those of you who may find interest in our equipment.

The software used for today’s analysis is typical of many of our reviews and consists of Piriform Speccy, ATTO Disk Benchmark, Crystal DiskMark, AS SSD, and QuickBench. In consumer reports, we prefer to test with easily accessible software that the consumer can obtain, and in many cases, we even provide links. Our selection of software allows each to build on the last and to provide validation to results already obtained.
Piriform Speccy is a great tool for checking the status and health of your computer system. It provides you with brief summary, or a detailed look, at your operating system, CPU, RAM, motherboard, graphics, storage, optical drives, audio, peripherals and network.
ATTO Disk Benchmark is a relatively easy-to-use benchmark tool, which happens to be the benchmark of choice for many manufacturers. ATTO uses compressible data rather than random data, which results in higher performance and thus, higher benchmark scores. In our testing, we have selected the transfer size to range from 0.5KB to 8192KB, and have set the total length of the test to be 256MB.
With our first benchmark test, ATTO brings us our test scores utilizing compressible data. The Marvel M70 returned read scores reaching 226 MB/s and write scores reaching 61 MB/s. Comparing to our listed scores, the write speeds are about half what we expected to reach, where as the read is almost reaching its mark. What is interesting is the jump in write speed at the 64 KB mark, with the sudden drop in write speeds right afterwards.
Crystal Disk Benchmark is visually straightforward, and is used for measuring the speeds at which your storage device reads and writes in both compressible (0Fill/1Fill) and random, mostly incompressible, data. Random data is more consistent with everyday use of a computer, such as transferring videos, pictures and music. We run the benchmark twice, using oFill data first, and then proceeding to test with random data.
With Crystal Disk Mark we see that using 0Fill data the read speed reaches 220 MB/s and the write speed reaches 69 MB/s. When we switch over to random data, we see an interesting, but slight, jump in read speed to 233 MB/s, where as the write speed stays the same.
AS SSD Benchmark uses incompressible data in their testing of SSDs, essentially providing results that would be consistent with using the heaviest workload, thus lower speeds are expected. Transfer speeds (MB/s) are seen in the left picture below and IOPS (Input/Output Operations Per Second) are on the right.
In AS SSD, we see that the Marvel M70 reaches 234 MB/s with read speeds and 79 MB/s with write speeds. When taking a look at the IOPS, the Marvel M70 comes back with 14 and 4 IOPS, respectively.
QUICKBENCH VER. 4.0
QuickBench is another benchmark tool used to measure the transfer speeds and performance of storage devices. QuickBench is a good tool for confirming the previously produced read and write speeds seen above.
QuickBench always proves to be integral to our analysis of a drive, as it typically shows us things we don’t normally expect from a drive. With QuickBench, the Marvel M70 returns write speeds reaching as high as 87 MB/s and read speeds reaching up to 197 MB/s. This is the first time we have seen the Marvel M70 exceed its listed write speed.
