Speed, Capacity, and Build Comparison
Read Speed
The Samsung BAR Plus offers a maximum read speed of 400MB/s. This allows you to transfer large files, such as 4K video, much faster than the Amazon Basics drive. The Amazon Basics model provides a maximum read speed of 130MB/s. While this is still fast for USB 3.1, it is significantly slower than the Samsung option. If you frequently move large media files between devices, the higher speed of the Samsung drive reduces wait times. The Amazon Basics drive is suitable for general storage where speed is less critical. The difference in transfer rates is substantial for heavy users.
Storage Capacity
The Amazon Basics drive provides 256GB of storage space. This is double the capacity of the Samsung BAR Plus, which offers 128GB. The Amazon Basics drive can store more photos, videos, and documents before you need to clear space. The Samsung drive is smaller in capacity but still sufficient for many users who only need moderate storage. If you require more room for your files without buying multiple drives, the Amazon Basics option is the better choice. The Samsung drive is adequate if you primarily use it for occasional file transfers or smaller collections.
Build and Durability
The Samsung BAR Plus features a rugged metal casing. It is described as waterproof, shock-proof, temperature-proof, and magnet-proof. This design protects your data in harsh conditions. The Amazon Basics drive has a retractable telescopic design with a keyhole. It uses high-quality NAND flash memory chips for data security. However, it lacks the comprehensive environmental protection ratings of the Samsung drive. The Samsung drive is built for durability and rough handling. The Amazon Basics drive is stylish and compact but may not withstand the same physical stress.
USB Version
Both drives support the USB 3.1 standard. This ensures backward compatibility with older USB 2.0 ports, though speeds will be lower on those ports. The Samsung drive leverages USB 3.1 to achieve its 400MB/s read speed. The Amazon Basics drive also uses USB 3.1 to reach 130MB/s. Both require a USB 3.1 Gen 1 or USB 3.0 port on the host device to achieve optimal speeds. This shared specification means both drives work with a wide range of modern computers and devices. There is no advantage for either drive in this specific category.
Physical Design
The Amazon Basics drive features a retractable design. This means the USB connector slides into the body, eliminating the need for a cap. It also includes a keyhole for attaching to a keychain. The Samsung BAR Plus has a solid metal body with an integrated keyring. It does not have a retractable mechanism. The Amazon Basics drive is more compact when not in use due to the retractable feature. The Samsung drive is slightly larger but offers a more robust physical structure. Your choice depends on whether you prefer a capless design or a rugged metal build.
