Kioxia flash 32 gb

Clean, Compact Design

KIOXIA’s TransMemory drives (such as U365, U366, U301, U202) all feature a sleek, lightweight form factor, typically weighing 6–9 g and sized between ~39×12×4.5 mm to ~55×21×8.5 mm .

2. USB Interface Options

Select from USB 3.2 Gen 1-enabled models like U365 and U366 (backward-compatible with USB 2.0), or more basic USB 2.0 versions such as U202 and U203 .

3. Up to 100–150 MB/s Read Speeds

• U365 (32 GB) supports up to ~150 MB/s read speeds 

4. Usable Capacity ~28.8 GB

Although marketed as 32 GB, actual formatted capacity available to users is typically about 28.8 GB due to filesystem overhead and formatting 

5. Compatibility Across Systems

Compatible with both Windows (8.1, 10, 11) and macOS (Catalina through Sonoma and Sequoia), depending on model and release date (as of May 28, 2025) .

6. Long Warranty Support

All models include a 5‑year limited warranty, offering peace of mind for long-term use 

7. Metallic & Retractable Design (U365/U366)

U365 features a matte black sliding (capless) cover; U366 sports a slim metallic housing and often includes a keyring loop for portability 

8. Reliable Brand Heritage

KIOXIA, formerly Toshiba Memory, holds a strong reputation in NAND flash manufacturing and is one of the world's leading flash-memory producers 

9. Performance Caveats

Despite claims of USB 3.2 Gen 1 compatibility, many users have experienced very low write speeds, sometimes slower than USB 2.0 drives. Examples report hours to transfer just 1 GB, or speeds around ~1–2 MB/s .

10. Best Use Cases

Well-suited for general file transfer, light document or media storage, occasional backups, and basic PC/Mac usage. Not ideal for bootable drives, frequent large writes, or tasks demanding high sustained write speed
