Features

Tool-Free Installation Function

This adapter requires a screwdriver for installation, making it less convenient than tool-free designs. The installation process involves securing the M.2 SSD with screws, which can be cumbersome for users who frequently swap drives. Tool-free mechanisms offer a quicker and easier way to install or remove SSDs.

External Heat Dissipation Function

The adapter does not have any external heat dissipation features like a heatsink or radiating fins. This can lead to heat buildup, especially with NVMe SSDs, potentially causing performance throttling. Without proper cooling, sustained high-speed data transfers may not be possible.

Write Protection Function

This adapter does not offer a write protection function. This means there is no way to prevent data from being written to the SSD, increasing the risk of accidental data deletion or overwriting. Write protection is useful for safely viewing or sharing data without the risk of modification.

UASP Support Function

It is not clear whether this adapter supports UASP (USB Attached SCSI Protocol). UASP enables faster data transfer speeds when connected to a UASP-compatible USB port. Without UASP support, data transfer speeds may be limited to the standard USB protocol, resulting in slower performance.

LED Indicator Function

The product information does not mention an LED indicator. An LED indicator would provide a visual indication of the adapter's operating status, such as whether the SSD is properly connected and transferring data. This can be helpful for troubleshooting connection issues.

Multiple Size Support Function

This adapter supports multiple M.2 SSD sizes, including 2280, 2260, and 2242. This provides flexibility when upgrading or repurposing existing SSDs. Users can use various sized SSDs with a single adapter, making it a versatile choice for different storage needs. This is a significant advantage for users with multiple M.2 SSDs of varying sizes.

Ranked #66 out of 66 products in Category
3.3
Overall Rating

This adapter offers a convenient way to connect M.2 SSDs to a computer via USB. However, its performance is limited by the USB 3.1 interface, and it lacks advanced features like tool-free installation and active cooling. It's a budget-friendly option for basic external storage needs.

Supported SSD Type and Size
4.5
This adapter supports both NVMe and SATA M.2 SSDs, offering versatility. It is compatible with multiple sizes, including 2280, 2260, and 2242, making it suitable for various SSDs. This flexibility is beneficial for users with different storage needs.
Interface and Transfer Speed
3.5
The USB 3.1 Type-A interface provides a data transfer rate of up to 10Gbps. While adequate for most tasks, it is slower than Thunderbolt 3/4 or USB 3.2 Gen 2, which offer higher speeds. This can be a limitation for users transferring large files frequently.
Cooling Solution
1.0
This adapter lacks a dedicated cooling solution like a heatsink or fan. This could lead to thermal throttling, especially during prolonged use with high-performance NVMe SSDs. Sustained transfer speeds may be affected due to overheating.
Build Quality and Material
3.0
The adapter is made of silicone, which may not offer the same level of durability and heat dissipation as aluminum. The build quality appears to be adequate for basic use, but it may not withstand heavy handling or harsh environments.
Portability and Size
4.0
The compact size and lightweight design make this adapter highly portable. It is easy to carry around and use with different devices. This is ideal for users who need to access their M.2 SSDs on the go.
Ease of Installation
3.0
The installation process is relatively straightforward, but it may require a screwdriver. Tool-free installation would have been more convenient. Users should refer to the instructions for proper installation to avoid any issues.
Manufacturer Reliability and Warranty
3.0
RIITOP is not a well-known brand, so its reliability and customer support may be questionable. Users should research the brand and read reviews before purchasing. A longer warranty period would provide more assurance.
Cost Performance
4.0
At $19.99, this adapter offers good value for its price. It provides basic functionality for connecting M.2 SSDs to a computer via USB. However, users should be aware of its limitations, such as the lack of cooling and the slower transfer speeds compared to higher-end options.

Frequently Asked Questions (FAQ)

Q.I'm looking to upgrade my PC's storage. Will this adapter work with my NVMe SSD?
A.Yes, this RIITOP M.2 to USB adapter is compatible with both NVMe (PCI-e channel) and B+M Key (SATA channel) M.2 SSDs. It supports various sizes including 80x22mm, 60x22mm, and 42x22mm. According to staff confirmation, it worked perfectly for upgrading an M.2 operating system disk.
Q.I'm not very tech-savvy. Is this adapter easy to use for cloning my old SSD?
A.The adapter is designed for easy use, but some staff confirmation indicates that instructions are not included. One staff member noted a peculiar screw design for securing the SSD, but overall, the process is manageable. Some users have successfully cloned their drives using this adapter.
Q.I want to use this adapter to transfer large files. Is it reliable for sustained data transfer?
A.While many staff members have had positive experiences, some staff confirmation indicates that the adapter may disconnect during large file transfers, particularly on Windows 11 systems. This issue may require a system restart to resolve. Consider this potential limitation if you plan to move large files frequently.
Q.Can this adapter be used to wipe an old SSD for a fresh Windows install?
A.Yes, according to staff confirmation, this adapter can be used to factory reset or wipe an SSD. This is particularly useful if you want to use an SSD from a previous build as primary memory for a fresh Windows installation.
