Best Enclosure for M.2 SSD

Under the influence of the faster and faster pace of the information age, everyone buys computers and mobile phones to be thinner and smaller, which requires every electronic component to reduce the volume while also improving the speed. As we all know, SSDs have the characteristics of fast reading and writing, light weight, low energy consumption, and small size that traditional HDDs do not have. Before the advent of NVMe, the vast majority of SSDs followed the AHCI and SATA protocols, and now, AHCI can no longer keep up with the pace of SSD performance development, and M.2 interface SSDs with smaller size and stronger performance supporting NVME protocol have appeared.
NVMe (Non-VolatileMemory express) is an AHCI-like protocol built on the M.2 interface, which is specially designed for flash storage. M.2 SSDs have changed the status of 2.5 inches, becoming thinner and shorter, and more comfortable to plug into the motherboard, and the M.2 interface solid-state that supports the NVME protocol has more bandwidth, faster transfer speeds, and greatly reduces the latency of the SSD. At this time, some players came up with the idea of transforming M.2 into a USB flash drive to use, and get a high-speed portable SSD that can be carried around.
Thus, the RSH-328 and RSH-329 SSD enclosures were born.

But do you know what features a good m 2 ngff ssd enclosure should have? Read this article carefully before purchasing and you will be able to buy the product you want.
I. Mainstream Solutions for M.2 SSD Enclosures
In the 10Gbps HDD enclosure market, JMS583, RTL9210/B, and ASM2362 are the three mainstream master control solutions, which are widely used in different brands of HDD enclosures. Each controller has its own characteristics in terms of performance, power consumption, heat generation, and compatibility, and the specific comparison is as follows:

(1) JMS583: Suitable for Large-capacity Transmission, But the Heat Generation is High.
JMicron launched JMS583 and has become a “veteran” in the market. With high stability and universal compatibility, JMS583 is widely adopted by many hard disk enclosure brands.
Here are the features of the JMS583:
Transmission Performance: The JMS583 has an actual bandwidth of 10Gbps, which is capable of being used in most common storage applications. In terms of performance, it is relatively stable when transferring large files, and the read speed can reach about 1000MB/s.

JMS583 does not support ASPM energy-saving function, which makes the power consumption high in standby mode. For daily use, you may need to pay attention to its power consumption.
JMS583 generates relatively high heat when working under load, especially in the case of long-term transmission of large files. It is recommended to choose a finished hard drive enclosure with a good thermal design to ensure its performance.
It supports firmware flashing, and users can customize the settings, which is suitable for players who like to DIY. However, compatibility issues may be encountered on some new hardware platforms, and it is recommended to confirm compatibility before purchasing.

Therefore, the JMS583 enclosure is suitable for users with frequent access to large files, but due to its high heat generation, it is recommended for use in desktop environments or devices equipped with thermal functions.

(2) RTL9210/B: Dual-protocol Support, Excellent Energy Consumption Ratio
Launched by Realtek, RTL9210/B is the only 10Gbps master control solution on the market that supports dual protocols (NVMe and SATA). This solution is known for its low power consumption and good temperature control, and it performs well in terms of overall performance.

RTL9210/B also supports 10Gbps transfer rate, and in the case of dual-protocol support, it can not only be compatible with NVMe SSD but also support traditional SATA SSD. This is very friendly for users with multiple interface needs, such as converting an old NGFF SATA interface SSD to a portable SSD.
The RTL9210/B supports ASPM energy-saving functions, so it consumes less power during standby mode, making it suitable for frequent movement or use. At the same time, Realtek’s power consumption control makes it less calorific, making it safer to use for long periods of time under heavy loads.
As a newer solution, its firmware updates are frequent, quick to fix issues, and easy to use, making it suitable for users who don’t want to go through complicated setups. Simple firmware flashing is supported to ensure that users can quickly get system compatibility updates.

Thus, the RTL9210/B enclosure is suitable for portability, usability, and stability under large write loads due to its low power consumption and low heat generation.

(3) ASM2362: Strong Performance, But Large Dependence on Firmware
ASM2362 is a master control solution launched by ASMedia, which is regarded as a representative of both performance and stability, especially for users who want efficient transmission.

ASM2362 supports a 10Gbps transmission rate, and its read and write speed is excellent at the same bandwidth, which can reach the actual read and write speed close to 1000MB/s, which is suitable for fast transfer of large files.
Under the default firmware, the standby power consumption of the ASM2362 is relatively high, but users can effectively reduce the power consumption and extend the standby time by flashing the firmware.
The performance and stability of ASM2362 depend on the firmware, and the right firmware can significantly improve power consumption performance and stability. The hard disk enclosure of this solution is slightly better in terms of performance, but it is necessary to ensure the stability and adaptability of the firmware.

Consequently, the ASM2362 hard drive enclosure is suitable for users who have high requirements for transfer efficiency, but it is recommended to choose a brand product with good firmware support and good thermal design.

How to Choose the Right Master Solution for Me?
For daily storage and general transmission needs, the JMS583 solution m 2 ngff ssd enclosure with 10Gbps bandwidth is sufficient to meet the needs, suitable for desktop users who do not need multi-platform compatibility. The RTL9210/B supports dual protocols and low power consumption, which is more suitable for notebooks, old hard disk modification, and mobile scenarios.

If the daily transfer of large files or frequent data copy, the ASM2362 high bandwidth solution is more suitable. It has high performance, and good compatibility, and is suitable for efficient file processing.

In addition to looking at the performance of the hard disk enclosure, you should also look at the following aspects:
II. Excellent Thermal Design:
The all-aluminum metal body and multi-groove design metal cover plate effectively reduce heat accumulation during operation. Inside the turbofan is added to actively dissipate heat, with high thermal conductivity silicone sheet and metal heat dissipation vest, to ensure the stability of the hard drive under long-term high load.

III. Easy to Install and Use:
Tool-free plug-and-play support allows you to install the drive in a box in just a few simple steps. Excellent compatibility, support Windows/MacOS compatible Thunderbolt 3/4 computer interface connection and use.

Ⅳ. Portability & Design:
Compact and lightweight, it has a modern industrial feel, making it suitable for any occasion, whether it’s a busy office environment or a shooting location.
