ICY Dock EZConvert MB703M2P-B M.2 SATA SSD to 2.5″ SATA SSD Converter Adapter Review


  • CPU: AMD Ryzen 9 3900X
  • Motherboard: ASUS ROG Crosshair VIII Hero
  • RAM: 16GB G.Skill TridentZ RGB 3200Mhz
  • GPU: Nvidia RTX 2080 FE
  • Drive: Crucial MX300 525GB SATA-III
  • OS: Windows 10 Professional X64



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

CrystalDiskInfo shows our drive connected at SATA-III 6.0 Gbps speeds as expected. This screenshot is during testing, showing our drive got up to a toasty 62C under full load. The MB703M2P-B does have the ability to accommodate a heatsink, and if using your SATA M.2 drive under heavy loads, you may want to consider it.


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”

While our drive is technically rated for 510MB/s, it comes in at around 460MB/s reads and 415MB/s writes in ATTO connected to the onboard M.2 slot. We are getting the same speeds here out of ATTO which is good.


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.”

We again get the same speeds out of CrystalDiskMark with writes hitting almost 490MB/s on writes.



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 is 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 comes in right around the 455MB/s mark, as expected.
