   OK, I see there is a story about rPi launching actual NVMe M.2 SSDs. As   
   opposed to a hat. I've no idea why they would do that. The obvious   
   suspicion is cashing in on a brand name.   
      
      
      
   It's hard to know what is going on with the Raspberry Pi guys, the   
   RK3588 devices are clearly faster, lower energy, albeit with shit   
   software support. Who knows what will happen with the next generation   
   Arm SoCs. I guess maybe Raspberry Pi have a clue, and hence decided to   
   monetise the brand now, before a new product wipes the floor with them.

   Dunno, IOPS doesn't mean a lot to me. As TNP says, maybe a write   
   operation is to cache, and a read is from main memory.   
      
   On many solid state persistence devices you see a very fast initial   
   write (presumably to cache) before quickly settling down to a much lower   
   rate for big files.
