Review on 💾 HP 256GB SDXC Flash Memory Card (P-SD256U395HPSX-GE), Class 10 U3 for Enhanced Performance by Jimmy Jefferson

The card is exactly as shown in the picture but is actually only 478GB, a lot less than 512GB! Where is the other 34GB? Even if there is a boot sector in front of this card, it shouldn't be that big for formatting purposes! I have other cards that don't have as great a format-only interface and which isn't specified by the manufacturer. It feels like I'm somehow tied to a purchase. Either way, it's still plenty of space to store old images or files that you no longer want on your computer or device.
