Expert Review Analysis

The Silicon Power SP128GBUF3B02V1K is a 128 GB USB flash drive with a slim black plastic chassis, weighing only 8 g and measuring 60.6 × 18.0 × 8.1 mm. It uses a USB 3.2 Gen 1x1 interface delivering up to 5 Gbit/s and achieves sequential read speeds around 210 MB/s and write speeds near 130 MB/s, making it suitable for bulk data transfers.

SP128GBUF3B02V1KBlack128GB 5 Year Warranty

USB Flash Drives Flash Memory Sticks

✓Sequential benchmark results show read speeds of 204–219 MB/s and write speeds of 124–135 MB/s, suitable for large file transfers.

✓Capless, low‑profile design eliminates a removable cover, reducing moving parts and potential loss.

Cons

✗Random 4 KB write performance is extremely low (≈0.24 MB/s), making small‑file operations painfully slow.
✗Multi‑threaded random I/O tests returned 0 MB/s, indicating the drive cannot handle concurrent workloads.
✗No information provided on encryption, endurance (TBW) or warranty, leaving durability unclear.
✗Benchmark data shows no advantage over higher‑end USB‑3.2 drives, limiting its appeal for power users.
✗Lack of professional reviews or consumer feedback makes real‑world reliability hard to assess.

From Expert Reviews

Praised by Experts

✓Benchmark site highlights sequential read up to 219 MB/s and write up to 135 MB/s, confirming strong bulk‑transfer performance.

Criticized by Experts

✗Professional testing points out random 4 KB write below 1 MB/s and zero multi‑threaded random throughput, rendering it unsuitable for small‑file or multitask scenarios.

Expert Opinion

Professional benchmark testing (SSD‑Tester) shows the drive excels at large‑file sequential transfers, reaching up to 219 MB/s read and 135 MB/s write, but its random I/O performance is abysmal, with 4 KB write speeds under 1 MB/s and no measurable multi‑threaded throughput, limiting its usefulness to simple backup or media‑shuttle tasks.

How It Compares

Compared with other 128 GB USB 3.2 Gen 1 drives, the SP128GBUF3B02V1K offers typical sequential speeds but falls behind on random performance, where many competitors achieve several megabytes per second. Its ultra‑slim profile and 8 g weight are advantages, but the lack of encryption and endurance specs make it a basic, budget‑oriented option.
