The YELLOW case T35es-RW is identical to the regular BLACK case T35es, except that the T35es-RW is pre-configured at the factory for read-write operation.
As with other Tableau products, forensic practitioners told us they wanted a dedicated bridge for use when making copies of forensic evidence. The YELLOW case highlights the fact that the T35es-RW is writable, eliminating the potential for mis-use during forensics examinations.
Often, a full forensics kit will include both write-blocked (BLACK) and read-write (YELLOW) forensic bridges, and you'll see that many of Tableau's resellers sell kits configured in just this way.
