Dates are decoded from SMI version codes: the letter is the year (J = 2010 … Y = 2025) and the four digits are month and day.
Controller
SM2258XT: SATA 6Gb/s SSD controller, 4 NAND channels, DRAM-less, LDPC ECC.
Function
Silicon Motion mass production tool package. It initializes the drive, loads the controller firmware, scans and records bad blocks, and writes the drive identity (model, serial number, capacity). Packages that include RDT firmware can run a burn-in test before the final firmware is loaded. Running the tool re-initializes the drive; existing user data is lost.

Flash database (60 entries)
The FW tag column comes from Firmware/2258/FWTag.SET and names the firmware build each part needs. Parts with another tag, or no tag, need a different firmware build.
Part numbers are copied as written in the database. Variant lists the bracketed qualifiers from the entry (voltage, die count, generation). Flash ID shows the first six ID bytes stored for the entry.
