Expert Opinion
Professional reviewers commend the drive’s retractable connector and sleek black design, noting that the 130 MB/s read speed delivers fast transfers. However, they criticize the modest 30 MB/s write speed and the disclaimer that performance may vary, positioning the product as a solid everyday solution but not a high‑performance option for power users.
What Users Say
Everyday users praise the reliability of the retractable mechanism, the convenient size, and the generous 128 GB capacity, often purchasing multiple units. Recurring concerns focus on the slower write speed and the reduction of usable space after formatting, with some noting inconsistent transfer speeds in real‑world use.
Common Complaints
Slower 30 MB/s write speed, loss of roughly 8 GB of capacity after formatting, and occasional variability in actual transfer speeds compared to advertised figures.
How It Compares
Compared to cap‑based USB flash drives, the Amazon Basics LS21USB128G1 stands out with its retractable connector that eliminates cap loss. Its 130 MB/s read speed is competitive for the price tier, but the 30 MB/s write speed lags behind premium USB 3.1 competitors that can reach 60‑100 MB/s, making it less suitable for heavy‑duty file writing tasks.
