K&ZZ USB Flash Drive 32GB/64GB 2 Pack Thumb Drives, USB 2.0 Memory Stick Portable Zip Drive with Black Lanyards for Data Storage 64G 2) 64GB 2 Pack

These mini thumb drives are amazing! Since cars no longer have CD players (ok, I'm old), I still wanted to hear some of my favorite tunes on the road. Since my newer car DID have a USB port as part of the entertainment system, I wanted to have a memory stick that would hold lots of music, leave it plugged in, and yet not stick out too far where it could be accidentally hit. These 64 GB mini flash drives are exactly what I needed. It is really hard to believe something so small has so much storage capability -- but they do! I really like their size and performance. I'm sure I'll find other uses, too!

Delivery OK.

There are many reviews complaining these don't work in embedded devices, but they're using 64+ GB disks. I specifically chose these 32GBs as the upper-limit to the CD player in the car. Write speed is low as others will mention. Some day 1MB/s, I see more than that but I see a bunch of big writes and big pauses. This is NOT the worst flash drive I've ever owned for write speed. It will be slower than uploading something, yes. Speed will go up and down inconsistently. Be sure to only let 1 thing write at a time, pause other copies or wait or use a file copy manager. See pic for what not to do, see up and down graphs. Putting this in a Kenwood CD player, on Shuffle All (shuffle folder & track), skips "instantly" to the next track, like quicker than a CD changing track. This is sufficient read speed for a few MP3s. I can't speak to the fake capacity issues others are having, I've written 29GB to this without noticing an overwrite loop yet. I can't speak to longevity, but I appreciate the other reviewers mentioning short-term failure. I'll be sure to use these for recreational things only, not as backups.

Big enough to easily pull out especially with linyard, but small enough not to snag on anything. I use them in cars for music.
