Hard drives are definitely a suspect item, they are counterfeited. I needed some 6TB Seagate drives ~6 months ago to replace the drives in a security NVR, our local supplier was out of stock and they were available on Amazon. The drives appeared genuine, they showed up in OEM style packaging which was expected, I connected 1 of 6 to a Debian machine to check it an it reported the correct capacity. Flash forward to 2 weeks later and I get a notification the storage is full, when the capacity should have been enough for 5-6 weeks of storage. Further benchmarking showed they were actually 2TB drives that reported incorrect size. Fwiw they did match the read/write performance if the genuine drives, which doesn't mean much since that class of drives isn't terribly fast but are supposedly optimized for reliability for drives that spend ~99% of their life continuously writing and rarely reading. At least Amazon took them back as a return and did offer a refund. I had thought it was only memory sticks and SSDs that were being counterfeited, but apparently that is also happening for spinning rust drives as well.
