Samsung Bar Plus Speeds Compared
Read Speed
The Samsung BAR Plus 128GB model offers a read speed of 400MB/s, while the 64GB version provides 200MB/s. This difference matters when you move large files. A 3GB video takes about 10 seconds on the faster drive, compared to 15 seconds on the slower one. You get double the throughput with the higher-capacity option. If you transfer 4K footage or large archives often, the 400MB/s drive saves time. The 200MB/s drive is still fast by USB 3.1 standards, but the gap is clear. Choose the 128GB unit for quicker access to your data.
Storage Capacity
Capacity is the other major split. The first drive holds 128GB of data, doubling the space of the second drive, which holds 64GB. You need more room for high-resolution photos, videos, and software installers. The 128GB option gives you breathing room for future files. The 64GB drive is sufficient for documents and smaller media, but fills up faster. Both use USB 3.1, so speed does not drop due to capacity differences here. If you carry many large files, the 128GB model is the practical choice. It reduces the need to manage storage space constantly.
Build Quality
Both drives feature a rugged metal casing designed for durability. The 128GB model has a gray metal body, while the 64GB version comes in champagne silver. Both include an integrated keyring to prevent loss. They share the same 5-way protection: waterproof, shock-proof, temperature-proof, magnet-proof, and X-ray-proof. The dimensions are nearly identical, with slight variations in height and length that do not affect fit. You get the same sturdy feel and protection regardless of which capacity you pick. The build quality is a tie, offering reliable performance in tough conditions.
USB Version
Both products use the USB 3.1 interface. This standard ensures backward compatibility with USB 3.0 and USB 2.0 ports. You can plug either drive into older computers, though speeds will drop to match the port's limit. The USB 3.1 connection supports the high read speeds listed in the specs. There is no difference in connectivity technology between the two models. You get the same bandwidth potential and plug-and-play convenience. The choice depends on capacity and speed, not the connector type. Both are ready for modern and legacy systems alike.
Write Speed
The 64GB drive lists a write speed of 30MB/s in its features. The 128GB drive does not explicitly state its write speed in the provided data, though it highlights fast read speeds. Write speed affects how quickly you copy files onto the drive. If you frequently save large files, the known 30MB/s rate on the 64GB model is a baseline. The 128GB drive may offer better write performance, but without explicit data, we cannot confirm. For now, the 64GB model has a stated write metric. The 128GB drive excels in reading, but write details remain unclear in the specs.
Which Samsung Bar Plus Should You Buy
You need fast transfers for large 4K video files
This 128GB model reads at 400MB/s. It moves a 3GB file in 10 seconds. The larger capacity holds more data. You benefit from the metal casing and five-way protection. This is the best choice for speed and storage.

This 64GB drive reads at 200MB/s. It copies a 3GB file in 15 seconds. The smaller size fits easily on a keyring. It shares the same rugged metal build and USB 3.1 port. This suits basic file storage needs.
You prioritize maximum read speed above all else
The 128GB version offers double the read speed of the 64GB model. You get 400MB/s versus 200MB/s. This halves your wait time for large transfers. Both drives share the same durable design. The faster speed makes this the superior performance option.
