I came across a couple of Reddit discussions today that bear sharing here.
One discussed the lack of care when buying items from Amazon "stores" (in this case Nikon cameras) and that the "stores" are not in fact businesses selling their own materials via Amazon. In some cases the items on the shelf are from several vendors and when an order is filled, whatever item is grabbed may or may not come from the vendor you chose. And because they don't do great quality control on returned items, you can get used or defective items. I guess so far I've been lucky, but I'm also careful. After looking through Amazon and finding odd offers and groupings of bundled items on the camera I was shopping I backed out and bought it from a New York City camera store (same price, but a much more reliable vendor).
The other thing is not a surprise, and I haven't had problems with SD cards I've purchased, but fake SD cards are what you get when lower quality or capacity cards are re-marked to look like the faster more expensive ones. (This is beyond the "you get what you pay for question" - if the price is too good to be true, you should already know that it probably is fake.) It's enough of a problem that there is software to test the speed and capacity of the cards you have. https://h2testw.org/. Has anyone tried this? From the site:
The program is incredibly easy to use, and it can be downloaded and installed on your computer free of charge. Once you have installed H2testw, all you have to do is plug in your storage device and select it from the program’s interface. Then, you can start the testing process, which will scan your device for its actual size and check for any bad sectors.
One of the best things about H2testw is that it can test a wide range of storage devices, including USB sticks, SD cards, and hard drives. This means that no matter what type of device you are using to store your data, you can use H2testw to ensure that it is functioning properly and has the amount of storage space that it claims to have.
Another great feature of H2testw is that it can provide you with detailed information about your storage device, including its read and write speeds. This information can be incredibly useful if you are looking to optimize your device’s performance or if you want to compare the performance of different storage devices.
H2testw is also a great tool for anyone who is concerned about the security of their data. By checking for bad sectors on your device, H2testw can help you identify any areas of your storage device that may be prone to data loss or corruption. This can be especially important if you are using your storage device to store sensitive information, such as financial data or personal documents.
