How to choose an External Hard Drive Enclosure/Docking Station?

JM-D2 by JetMedia supports 2.5 3.5 inch SATA HDD/SSD, M.2, and USB3.1 in one device.

 

For professionals in computer repair or DIY enthusiasts who work outside, it is often necessary to carry multiple devices with various interfaces for USB-HDDs. It is also common to encounter storage space insufficiency or a full hard disk slot requiring expansion when using a desktop computer at home. Common storage devices include USB, USB-HDDs, SSDs, and Hard Disk Drives, all of which may require external devices.

 JM-D2, a multi-purpose docking station that meets these needs, has been introduced in JetMedia. It not only supports NVMe/SATA dual-protocol SSDs but also has two USB3.2 expansion ports that can read and write simultaneously without interfering with each other's speed. It can also externally connect 2.5/3.5-inch SATA hard drives.

 

 

 

 

Product Features:

  1. The flat-open design is convenient for insertion and removal without using screws and can prevent damage to hard drives due to collisions.
  2. The multi-functional device is compatible with NVMe/SATA dual-protocol M.2 SSD, 2.5/3.5-inch SATA hard drives, and two USB3.2 expansion ports that can support USB and USB-HDDs.
  3. Each port can read and write simultaneously, and it can work normally when fully inserted.
  4. It has independent power, allowing for extended connection to the computer and reducing the need for safe removal time.
  5. 3.5-inch mechanical hard drives typically have high power consumption, so an external power supply port (DC 12V/2A) is available to ensure stable reading and writing of high-capacity, high-power hard drives.
  6. Accessories include a heat-dissipating aluminum heatsink and silicon sheet to prevent overheating during M.2 data transmission.
  7. The speed of USB3.2 Gen2 can reach up to 10Gbps.
  8. The compact body is easy to carry when working outside.
  9. The original warranty period is two years.

Introduction to the product

  • Connect the entire unit as shown in the following picture ▼

 

  • When reading a 3.5-inch hard drive or multiple hard drives, please plug in the power supply (DC 12V/2A) to increase power supply ▼

 

Steps for using the product

 

  1. Plug in the device to be read by JM-D2
  1. Connect to the computer using a USB transfer cable and plug in the power supply
  2. Turn on the switch to power on the device
  3. Once the corresponding device indicator light is on, the device can be used normally

Orange: power switch

Blue: M.2 interface

Red: SATA interface

 

To remove the device, you can change the hard drive at any time after turning off the power.

 

JM-D2 supports NVMe/SATA dual-signal SSD and can be inserted with M key or B+M key SSD, with an anti-misinsertion design. The positioning of the rubber plugs can also be freely changed to secure SSDs of different sizes (22*30 mm, 22*42 mm, 22*60 mm, 22*80 mm).

 

Actual Test

The commonly used speed specification USB3.2 Gen2 can reach up to 10Gbps (approximately 1250MB/s).

The following data was obtained through testing using existing devices in the Jetmedia laboratory.  

※Test results may vary depending on the device and environment.

 

 

  • Test configuration:

Processor: AMD Ryzen 5 3600 6-Core Processor 3.6GHz

Motherboard: MSI X570-A PRO (MS-7C37)

System Disk: WD SN520 512GB

Operating System: Windows 10

 

 

▼1. Device: SAMSUNG 2.5-inch solid-state drive 860 PRO

Official speed: Up to 560MB/s read and 530 MB/s write speeds

 

If the test computer has Gen2 speed, the speed of the 2.5-inch hard drive itself can be measured. However, this is directly related to the performance of the hard drive itself. For more accurate results, it is recommended to use a faster or brand new hard drive for testing.

 

▼2. Device: SAMSUNG M.2 NVMe 980 PRO

 

 

Conclusion
