  1. Swindlers aren't even going to bother gaming the benchmarks. They're just going to counterfeit fake devices from low grade NAND, same as they do now.

  2. I don't know, I can't help but laugh at 500 IOPS write performance. An average USB 3.0 flash drive can do 2000 IOPS and that's ignoring the performance models.Are these limitations of the SD controller or are these cards just not capable of parallel writing across flash/NAND die?

  3. WOWThat was a waste of timeForget overly complex setups with iometer and go for a simple repeatable method that give ACCURATE results, like copying and pasting a non compressible fileTry 10GB and one of 100GB and see if the numbers match your iobullshit”Remember to reboot between tests to get an accurate and repeatable number without caching issues”Keep it Simple St……um DannyAs for PNY….I bought a newegg sale PNY USB3 thumb drive that barely reached 1/2 of claimed write speed although I admit it might have been a newegg advertising problem and not the fault of PNYBut, when I bought a PNY SD card that was rated at twice the write speed that I was seeing in actual use using test gear that far exceeded PNY specs when testing much better cards, I knew there was a problem with their labelingProduct labeling should list the max transfer rate of the worst unit sold under actual end user conditions (Not the Best unit they can find under very specific ideal conditions)

  4. Sequential speeds and IOPS do not tell me how fast an SSD or SD card actually isWhy does a Samsung 850 Pro copy and paste data to and from the same SSD twice as fast as a Samsung 840 Pro when the performance numbers provided do not indicate a doubling of internal throughput, instead providing numbers that indicate “external” throughput (To or from the drive but not both simultaneously)and how does labeling an SD card make PNY suddenly start labeling accurately?Grab any 2 SSD's with different internals but similar specs and prove me wrong!Start testing what matters

  5. No there's not. Not in every case. Take a look at SLC vs. MLC vs. TLC vs QLC — the faster types are more reliable/durable, they're just more expensive.

  6. The problem is… There's always a trade-off between performance and reliability.

  7. And in completely unrelated news, the Crap Flash Swindlers Association has announced that once again it's figured out a way to game the new benchmarks so that they can put the same performance labels on their cut-rate binning rejects – that the SD Card Association expected would only be possible on top tier cards – without actually improving their crappy cards usability in real world situations.(Cynical? Why yes I am.)
