Professional reviewers commend the PNY PRO Elite for its impressive 400 MB/s read capability and solid benchmark score, highlighting the metal construction and 64 GB pSLC cache as strengths. However, they consistently criticize the steep drop in sustained write speeds once the cache is exhausted and the lack of a USB-C interface, positioning the drive as a strong read-focused solution but limited for heavy, continuous write workloads.
Everyday users generally appreciate the rapid read performance and generous 256 GB capacity, noting the drive feels robust and portable. Recurring themes in consumer feedback include frustration with slower sustained writes after the cache fills and occasional warmth during prolonged transfers, while the missing USB-C option is also mentioned as a drawback.




The Kingston IronKey Locker+ 50 32GB is a compact, enterprise-grade encrypted USB flash drive featuring FIPS-certified AES-256-bit XTS hardware encryption and a metal silver casing with a key loop. It offers plug-and-play use on Windows and macOS, USB 3.2 Gen 1 speeds up to 145 MB/s, and optional cloud backup via USBtoCloud.
Everyday users appreciate the drive's quick read response and convenient keyring design, but the overwhelming complaint centers on sluggish write speeds and occasional data integrity problems. Overall sentiment is mixed, with many recommending it only for light, read-heavy use.
