Spec: Japan page spec: WESTERN DIGITAL external HDD, USB-A connection, My Book 2021 (Mac/Windows 11 compatible), black, WDBBGB0040HBK-JEEX [4TB/desktop type] | original product name WESTERN DIGITAL USB-A connection My Book 2021 (Mac/Windows 11 compatible) black WDBBGB0040HBK-JEEX [4TB/desktop type] external HDD; Taiwan page spec: 4TB/3.5-inch desktop/USB-A/black/WDBBGB0040HBK-SESN/3-year warranty
Same-item basis: Japan lists model WDBBGB0040HBK-JEEX; the Taiwan momo product's model is WDBBGB0040HBK-SESN — both share WD's official base part number "WDBBGB0040HBK" (same 4TB capacity, same black color, same My Book 2021 redesigned enclosure, same Mac/Windows 11 support), differing only in the trailing 4-character regional code (-JEEX is the Japan sales code, -SESN is the international/Taiwan sales code) — WD's usual cross-region naming convention for the same drive, not a spec difference, so it can be treated as the same product. Price check: Japan ¥29,480, Taiwan NT$5,290; the conversion (5,290×4.8=25,392) is close to the yen price, a reasonable price gap with no anomaly. root re-verified on 2026-09-15: re-read the price from the Taiwan retailer's product page or momo's product-search JSON, confirming it is a single-SKU amount rather than a multi-spec price range.
