20Gbps M.2 NVMe enclosure with heatsink

The Yottamaster enclosure houses a single M.2 NVMe SSD and connects through a USB 3.2 Gen 2x2 Type-C port rated at 20Gbps. An aluminium shell and thermal pad dissipate heat without a fan. It accepts 2230, 2242, 2260 and 2280 modules in M-Key or B&M-Key form factors up to 4TB.

Suits users with a 20Gbps USB-C port.

Full 2000MB/s read and 1980MB/s write speeds require a host USB 3.2 Gen 2x2 connection. On a 10Gbps Type-A or Type-C port the enclosure falls back to lower throughput. It also does not suit builders who need multiple drive bays or Thunderbolt connectivity.

20Gbps USB 3.2 Gen 2x2 interface decides

The single specification that determines whether this enclosure delivers its rated performance is the host USB 3.2 Gen 2x2 port. Without that exact interface the drive will operate at reduced speed.

Questions about this item

What host port must my computer have to reach the quoted 2000 MB/s read speed with this enclosure?

A USB 3.2 Gen 2x2 Type-C port is required; without it the enclosure will fall back to slower speeds.

Will the included 2-in-1 cable still deliver full performance when I use the USB-A end on an older port?

The USB-A connector is limited to 10 Gbps, so maximum throughput drops to roughly half the 20 Gbps potential.

How can I confirm the thermal pad and heatsink are keeping my SSD within safe temperatures after installation?

Monitor the drive temperature in your OS or SSD utility; it should stay well below the throttle point under sustained loads.
