Really good drive, metal case helps dissipate heat but hardly feels warm. It has 2 small blue LEDs that blink when active (very small). I tested with a SanDisk Pro 500MB drive and it ran faster in every test. It's not as fast as Samsung 500MB or 1TB drives, but within 5-10% in writing and 5% in reading. And it's a lot smaller and seems more durable. Tested on HP x360 with USB-C and USB-A connections; USB-C is faster, but not by much, especially for casual activities. USB-C packages are always faster. But I bought first to try the new USB rPi boot for rPi4 after I updated the eeprom boot to the 06/15/2020 version; and it worked without any problems, now my rPi doesn't have a micro sd card - VERY happy with it. Wanted the smallest drive possible and it fits the bill, will buy 2 more and upgrade more rPi to this faster and more reliable drive. For the price (250MB and 500MB) it's the best value you can buy (1TB might be a bit cheaper).
