    this review is purely based on performance not longevity. just received this drive and connected to a usb 3.0 port on windows 11 machine. copied a 1gb test file from a SSD and sustained write speed is 33-35 MB/sec in windows. Copied same file back to the SSD (ensured it wasn't cached by unplugging drive then plugging back in) and read speed is very respectable at 145 MB/sec. was expecting better performance but for $10 i guess can't complain much. would be 2 stars but gave it 3 stars for the price. good for write few read many scenario but too slow write for my taste and will be returning.

    I haven't used it much as of yet. Lexar was my first attempt at 128 because it was on "sale." Device failed after 4th long transfer (40gbs on and off). This hasn't failed yet. It hasn't been a long time.
