After over a decade in the industry, we’ve finally decided to release a Flash study. This will be an ongoing project, so make sure to keep checking this page for updated reports. If you have anything to contribute or any questions, feel free to leave a comment or send us an email.
Back when we initiated the customized USB industry eight years ago, a lot has transformed. Prices have dropped significantly, market demand has surged, and technology has advanced. Today, we stock more drives than we did when we first started. Over the years, we’ve encountered various types of drives and consistently aimed to use the most reliable components. Here’s what we’ve learned:
- Most NAND Flash is manufactured by Samsung, Toshiba, Micron, Hynix, and Intel.
- The smallest capacity currently produced by the aforementioned NAND Flash manufacturers is 8GB. Any smaller capacities you find on the market are typically made from downgraded Flash.
- Downgraded Flash comes from higher-capacity chips that contain defective sectors. These sectors are isolated, and the chip is repurposed for the next smallest capacity (for example, an 8GB chip with defective sectors could be used as a 4GB drive).
- The USB Controller is crucial for the functionality of the USB drive. The combination of the Controller chip, Flash chip, and other components determines the overall quality of the USB drive.
- In the OEM market, the most popular controllers include Alcor Micro, SMI (Silicon Motion), and Chipsbank.
For this study, we’ve tested several branded USB drives sourced from our partners, along with some OEM drives that we either assembled ourselves or sourced directly from China. We’ve used—or previously used—all of these components based on customer budgets and technical requirements.
We utilized CrystalDiskMark to measure sequential read/write speeds using both 50MB and 1GB (1000MB) test sizes. Additionally, we used Check Flash to detect any errors in the drives.
