Tom’s Hardware reported smooth operation with the Steam Deck, but a finicky connection with Nintendo Switch 2. Neither Nintendo Switch nor Switch 2 can use the dock’s SSD, according to the publication’s hands-on review. The Mount Ling 2 Pro is most compelling if you want a dock with storage expansion and video capture for a Steam Deck; its Nintendo results come with more caveats.
What the Mount Ling 2 Pro combines
The Mount Ling 2 Pro combines a handheld dock, an M.2 NVMe SSD enclosure and a built-in capture card. Its SSD bay supports drives up to 4TB in the 2280, 2242 and 2230 sizes. The dock also has HDMI 2.0 output up to 4K at 60Hz, USB-C power delivery up to 100W and a USB 3.2 Gen 2 host connection rated at up to 10 Gbps. Tom’s Hardware published its hands-on review on November 3, 2026.
The dock’s screen displays HDMI, SSD and power information, while touch controls provide access to settings and fan controls. The single 40mm fan can run automatically, be adjusted manually or be turned off. Other connections include Gigabit Ethernet, USB-A ports and optical audio output.
Steam Deck and Switch 2 behave differently
Tom’s Hardware described operation with Steam Deck as seamless. To use the dock’s SSD with that handheld, the reviewer says to partition the drive in desktop mode and create a Steam games folder.
The same review found a less reliable connection with Nintendo Switch 2: it reported connection drops, multiple attempts before HDMI passthrough worked, and occasional dock reboots after an incorrect connection order. In that test, the dock was connected first, then the Switch 2 was unlocked and connected to the dock’s bottom USB-C port. The top port did not work in that test. Tom’s Hardware also says neither Switch model can use the dock’s SSD.
What the SSD speed result measures
In CrystalDiskMark, Tom’s Hardware recorded sequential reads and writes of about 820 MB/s using a 2TB WD_BLACK SN770. Random performance was substantially lower. That result belongs to the tested drive and setup; the dock’s USB 3.2 Gen 2 connection is rated at up to 10 Gbps, which the review identified as the limit on sequential transfer speeds.
The WD_BLACK SN770 is rated for sequential reads up to 5,150 MB/s when installed directly in a motherboard. That is the drive’s direct-install rating, not a result measured through the Mount Ling 2 Pro.
Capture software and the standard-versus-Pro choice
The capture card does not record on its own. Tom’s Hardware says DockCase supplies no capture software, so you need a host application such as OBS to capture or stream video. The review describes HDMI 2.0 output up to 4K at 60Hz.
Tom’s Hardware identifies the internal capture card as the stated hardware difference between the standard Mount Ling 2 and the Pro. The extra USB-C port serves a different role on each model:
| Model | Internal capture card | Additional USB-C port |
| Mount Ling 2 | No | USB 3.2 Gen 2 port |
| Mount Ling 2 Pro | Yes | Capture-card output |
If capture is part of your setup, the Pro adds the built-in card, though you still need host software. If you mainly want storage with Steam Deck, the standard model has the same listed SSD capacity and the extra USB-C port functions as USB 3.2 Gen 2. For Nintendo handhelds, the dock’s SSD is not usable, and the Switch 2 connection results Tom’s Hardware reported were finicky.
