Translation guide
Refers to built-in memory in devices like phones, computers, and cameras. In Japanese, the most common term is 内部ストレージ, but other expressions exist depending on context.
内部ストレージ
internal storage (of a phone/device)
The non-removable storage inside a smartphone, tablet, or similar device, as opposed to an SD card or external drive.
The standard term used in device settings and by tech-savvy users. Directly translates to 'internal storage'.
写真は内部ストレージに保存されています。
The photos are saved in the internal storage.
Often used in manuals or spec sheets to mean the device's own storage, emphasizing the main unit rather than external media.
本体ストレージの空き容量が不足しています。
The device's internal storage is running low.
Means 'built-in storage'. Common in technical contexts, but slightly less frequent in everyday settings than 内部ストレージ.
このモデルは内蔵ストレージが128GBです。
This model has 128GB of internal storage.
Refers to memory inside a computer or electronic device, sometimes distinguishing between storage and RAM. In Japanese, 内部記憶装置 is a direct translation but less common in consumer contexts.
Formal technical term for 'internal storage device'. Used in computing textbooks or specifications, but rarely in everyday conversation.
内部記憶装置の容量を増設する。
Expand the capacity of the internal storage device.
Can mean internal memory (RAM or storage) depending on context. Often used for RAM in PCs, but may appear for storage in embedded systems.
このマイコンは内蔵メモリが少ない。

All three are used for 'internal storage' in consumer electronics. 内部ストレージ is the most common in Android/iOS settings. 本体ストレージ emphasizes the device itself and is often seen in manuals. 内蔵ストレージ is slightly more technical and used in specs. In most everyday situations, 内部ストレージ is the safest choice.
The word-for-word translation 内部の貯蔵 is unnatural and not used for digital storage. Always use ストレージ or 記憶装置 in technical contexts.
