SK hynix Beetle X31

Name: SK hynix Beetle X31
Brand: SK hynix

Rare onboard DRAM cache at this price class supports steadier file-table handling than DRAM-less rivals. Teardown confirms thermal pads and metal shields front and rear, backing up the champagne-aluminum shell's cooling claims.

WHY THE PRICE IS JUSTIFIED

The scarce-at-this-price DRAM cache, own NAND/controller ecosystem, thermal pad/shields and a real aluminum enclosure explain the cost. It is a design-led drive, but the construction is backed by a teardown rather than just styling.

MATERIALS

Outer chassisAluminum

Protects the drive and spreads heat.

PCB heat protectionThermal pad and metal shields

Teardown-confirmed heat path on both sides of the board.

StorageTLC NAND plus onboard DRAM

DRAM helps mapping and transfer consistency relative to DRAM-less rivals.

CRITERIA

7/10

Sustained Writes

Independent reporting places post-cache sustained writing around 804MB/s.

8/10

Thermal Design

Teardown found a thermal pad and metal shields front and rear.

9/10

Host Compatibility

10Gbps USB 3.2 Gen 2 is broadly usable.

9/10

Controller And NAND

Onboard DRAM and SK hynix NAND/controller integration.

7/10

Durability And Seal

Aluminum body and 2m-drop rating, but no IP seal.

8/10

Capacity Value

Typical $95/TB is fair for DRAM-equipped 10Gbps storage.

9/10

Ergonomics And Extras

Compact curved form, case, two cables and status LED.

IDEAL FOR

·Design-conscious everyday users
·Photo offload
·10Gbps laptop storage

NOT FOR

·Wet/dusty use
·Multi-hour high-bitrate recording

DESIGN & ERGONOMICS

The curved champagne-gold metal body is unusually handsome and tactile. It is compact, has an LED, and includes a clear protective case and two cables; more charming than generic black slabs.
