Deal verdict: a solid budget USB-C flash drive
The SanDisk CZB Series is a family of compact USB-C flash drives that offer up to 256GB of storage and 250MB/s read speeds at entry-level prices, aiming to give budget-conscious users a practical, portable SSD alternative for everyday file transfers and backups without paying for premium external storage.
SanDisk’s new CZB USB-C flash drives start at USD 19.99 (approx. RM90) for the 64GB model, down from a retail price of USD 24.99 (approx. RM112). The 128GB version is listed at USD 24.99 (approx. RM112), while the 256GB drive is marked at USD 53.99 (approx. RM242) but currently sells for USD 42.99 (approx. RM193). Separate listings show the same capacities offered at USD 20 (approx. RM90), USD 25 (approx. RM116), and USD 43 (approx. RM193) respectively. At these figures, this is a fair, affordable storage deal: you get modern USB-C connectivity, decent performance, and a three-year warranty without overspending on a full portable SSD.
Specs and performance: fast enough for daily workloads
As USB-C flash drives, the CZB series focuses on straightforward, modern connectivity: a thumb drive form factor with a native USB-C plug that works with current laptops, phones, and tablets that do not include USB-A ports. All models use the USB 3.2 Gen 1 standard with bandwidth up to 5Gbps and advertised sequential read speeds of 250MB/s, which makes opening and copying files feel responsive for most day-to-day tasks. According to SanDisk, these drives are well suited for quickly transferring documents, backing up photos, or moving a handful of large files between computers, though they are not meant to replace a high-speed external SSD for editing heavy video workloads directly off the drive. You can choose among 64GB, 128GB, and 256GB capacities, and the 256GB flash drive is said to hold roughly 60,000 photos depending on file size.
Design, portability, and how it compares to SSDs
The CZB Series is built for portability and simple everyday storage. Each drive comes in a small black casing with a hole that lets you attach it to a keychain or lanyard, and the body measures 1.94 x 0.81 x 0.46 inches while weighing about 6g, so you can keep it in a pocket or bag without noticing it. It works out of the box with Windows 10, Windows 11, and macOS Monterey or newer, and an optional app is available if you prefer guided file backup over manual drag-and-drop. As a portable SSD alternative, it trades peak performance for price and convenience: SanDisk’s 250MB/s read rating is half of the 500MB/s speeds offered by some portable SSDs with dual USB-C and USB-A connectivity, but the CZB drives undercut those premium solutions while still delivering fast transfers for typical documents and photo libraries.
