USB Flash Drive Rankings (Price vs Performance) April 2024 USB Rankings

We highlight the best USB flash drive in terms of balanced performance and value for money using current prices, sequential read, sequential write , 4k read and 4k write speed. The speeds are combined to form a single effective speed which measures performance for tasks such as copying photos, music and videos. Effective speed is adjusted by current price and capacity to yield value for money. Finally thousands of individual user ratings are used to validate our benchmark figures. [USBFlashPro]

Good point (()). Yup, Snow Leopard uses SI prefixes (1 kilobyte = 1,000 bytes) rather than the more-traditional-though-incorrect binary prefixes (1 kilobyte = 1024 bytes). …and TiVo’s web interface used SI prefixes for as long as I can remember (at least Series 2 and onward, possibly), so TiVo wins on using SI prefixes (and unfortunately confusing geeks) first, at least in my world. I’m not aware of any other systems that have normalized to SI prefixes yet. https://drobocommunity.m-ize.com/t/17-5-tb-available/2156/3
