External¶
The rubber bumper peels off first. The external labels confirm the commercial identity: model LRD0TU1 (“Rugged USB 3.0 Thunderbolt”), S/N NL6B05HS, 2019, assembled in Thailand. Six Phillips screws are exposed: two short ones on the flanks around the USB port, and four long ones on the underside.
Insides¶
Inside, a bare Crucial BX500 (CT2000BX500SSD1, FW M6CR030, SATA 6 Gb/s, assembled in Mexico) plugs directly onto a U-shaped SATA connector on the board.
SSD¶
The Crucial/Micron BX500 is a DRAM-less TLC SSD with a dynamic SLC cache.

Chips¶
The board is a dual-path design with two independent SATA bridges, one per interface:
| Designator | Block | Manufacturer | Model | Role |

| U3 | Firmware (SATA/PCIe bridge) | Macronix International Co., Ltd. (MXIC) | MX25L5121E | 512K-BIT [x 1] CMOS SERIAL FLASH MEMORY |
| U4 | Thunderbolt (PCIe) → SATA | ASMedia | ASM1061 | PCI Express 2.0 to SATA 6Gbps Controller |
| U5 | SATA switch | ASMedia | ASM1456 | SATA 6G Mux/Demux Switch |

| U7 & U9 | Power | ? | ? | Unidentified Markings: AEHJ25345Package: plastic, 12 contacts (5 + 5 on long edges, 1 + 1 on short edges) |

| CON1 | TB Connector | ? | ? | Thunderbolt interface entry point to integrated miniDP cable |
| CON2 | USB Connector | ? | USB Micro-B SuperSpeed | USB 3.0 interface entry point |
| CON3 | ? | ? | ? | Unpopulated. 4 pins. Debug/UART for U13? |
Comments¶
The copper tape under CON1 is only a mechanical strain relief for the fixed Thunderbolt cable. There is no Thunderbolt controller on the board. This is the key architectural point: Thunderbolt is native PCIe, so the ASM1061 plugs directly onto the Thunderbolt lane. The Thunderbolt-to-PCIe conversion happens host-side, not inside the enclosure.
So the two paths resolve to:
Thunderbolt → CON1 (fixed mDP cable) → (PCIe 2.0 x1, 5GT/s) ASM1061 (SATA 6Gb/s) → ASM1456 → SATA
USB 3.0 → CON2 → (USB 3.0, 5Gb/s) ASM1153E (SATA 6Gb/s) → ASM1456 → SATA
This explains the throughput ceiling measured on both interfaces: the BX500 is the current bottleneck. However, the theoretical ceiling is set by the SATA bridges themselves on their outbound interfaces (ASM1061 capped at 5GT/s by its single PCIe 2.0 lane on the TB side, ASM1153E capped at 5Gb/s on the USB side), despite the drive negotiating a clean SATA 6Gb/s in both modes. Ultimately, the bridges’ outbound interfaces set the limit to a maximum effective speed of ~500 MB/s.
Upgrade¶
When planning a drive upgrade, anything rated above 500 MB/s would be wasted.
Serious candidates:
Budget: Micron/Crucial MX500 (up to 2TB) for its DRAM, providing better IOPS and sustained write performance;
High-capacity: Samsung 870 QVO (up to 8TB) for its ample storage, though the QLC endurance and sustained-write performance drop (to ~160 MB/s) once the SLC cache is exhausted;
High-end: Samsung 870 EVO (up to 2TB) for its DRAM + SLC cache, providing the best endurance and consistent performance.
