M.2 SSDハードドライブをコピーする方法:HDDデュプリケーター対ドッキングベース

When it comes to copying an M.2 SSD drive, apart from the common Docking base, an HDD duplicator is actually a cost-effective option. Here is a simple comparison of a UReach SP101 and an M.2 Docking base.

We used a 1TB M.2 NVMe SSD to copy a 30GB system file for testing.

Figure 1: A common M.2 Docking on the market

Docking only has a Full Copy function. Even though the SSD has only 30GB of data, it took about 126 minutes to completely copy the 1TB SSD while the SP101 duplicator supports System and Files Copy, which automatically analyzes the hard disk drive and performs bit-for-bit copying. It only took 4 minutes to finish copying the 30GB data. It is obvious the difference between an HDD duplicator and a docking base.

in time is very impressive. It’s about 30 times faster if with an HDD duplicator.

Fig. 2: The UReach SP101 M.2/SATA duplicator supports System and Files Copy.



Fig. 3: UReach SP101 shows the time progress when copying data, and the System and Files Copy function will automatically analyze and only copy the data area.


Fig. 4: The M.2 Docking only shows four percent progress, not showing the time of copying. It is relatively less intuitive for users.


If the capacity of the target device is smaller than that of the source device before copying, the duplicator will alert you in advance, and during the copying process, it will display in real time the copying time, percentage and data amount, and can set to skip bad sectors, etc.


After the copy is completed, the duplicator can compare the data of the source and the target device to make sure that the data copied to the target is consistent with the source. However, a docking base cannot warn in advance, resulting in a waste of time.

The SP-151 duplicator also supports the erase function, which can erase, recycle or reuse the SSD hard drives to ensure that important data is not leaked. It can also perform the Secure Erase function to restore the long-used SSDs to their original settings to increase speed (*Please note that SSDs need to support the Secure Erase command. The SP-151 supports the P9 speed-up function). In addition, the SP101 duplicator supports M.2 (NVMe/SATA) and SATA cross-interface copying while M.2 Docking only supports M.2 NVMe copying.

The following comparison table is for your reference:



M.2 Docking

Copy Modes

System and files Copy,

Full Copy, Partition, and Percentage Copy.

(With Skip Bad Sector function)

Only Full Copy

It takes a lot of time to clone a large amount of data.

(Without Skip Bad Sector function)



Only M.2 NVMe


Bit-for-bit comparison, CRC checksum

No (Docking cannot verify

if the result is correct)

Time Spent in Copying 30G

4:11 (INTEL 760P 1TB)

2:06:11 (INTEL 760P 1TB)


Real-time progress, percentage, and copy time display

(More intuitive)

Progress light display like 25/50/75/100%

(Less intuitive)

If the Source Capacity is Bigger

Failure warning will appear before copying

No (may fail after copying)

Additional Features       

Multiple ways to erase hard drives.

Supports P9 speed-up function

Cell phone OTG (cell phone should be able to support).

Connects to a PC to read data

F/W Update



Stand-alone Operation (It can work without a PC)

Possible (FPGA stand-alone architecture)
