:-BROKE it seems like, most pen/flash/thumb drives out there, have poor design. They stay warm even when idle. I've also noticed, some memory cards like Samsung do it to.Poor voltage conversion system maybe? Really bugs me out when you think, heat kills flash memory in no time. I wonder how much current they consume when idle |

It would be very easy to measure it if you were curious. I have not really noticed flash drives getting uncomfortably hot, maybe a bit warm but not enough to be a problem. I can't actually think of any that I've had fail either, I still have several very old 128MB pen drives that still work fine. |

Pretty much every USB drive I have come across used linear regulators for the various voltage rails. Back in the day, there was a microcontroller based data logger (that logs data to a USB drive) which exploited that by allowing the 5V supplying the USB drive to be reduced to keep it running cooler. --- Quote from: Raj on May 21, 2020, 03:37:10 am ---Really bugs me out when you think, heat kills flash memory in no time. --- End quote --- I read somewhere that heat actually improves endurance slightly. |

Standby for testing on computer Edit: same idling on computer... And 60mA and 70mA current while writing to em Other things I just measured : My rapoo mouse dongle, while active-35mA (I wonder what a normal mouse consumes) (mouse seems to use single AA at 2-10mA) Razer deathstalker ultimate-300mA on each of its usb Xbox controller-idle 20mA,100mW Chink joystick hotas-idle 11mA,55mW (Couldn't test while it vibrates, I have no testing software) Seagate portable hdd,idle-800mW-400mW (startup) 400mA (idle, reading, wiring (operating)) 250mA ejected |

My Sandisk CZ880 (SSD disguised in a flash drive's body) runs burning hot when idle and consumes 200mA+ doing nothing. --- End quote --- Might be the difference between memory management controller, since I think pen drive and ssd use the same technology. (oh wait...SSD usually have ram too. |
