Staff bump much?

I own lower capacity version of the Dual.
Generally have found it to be very useful, I have it on my keychain. great for on the go transfers between phone and computer

It does have a couple flaws:
1. The side slider that extends either the C or A plug wears quickly and stops locking, so you have to hold it in place/forward while plugging into a port or the plug just retracts. Bit of an annoyance, but product still functional
2. Tiny attachment point for lanyards. Really can only fit string through it, not a keychain ring.

Just ran USB Flash Benchmark, enjoy (screenshot resuts attached):

Max Read: 145MB/s
Max Write: 39 MB/s

*Note: ran benchmark using the USB-C side...not sure it would make any difference.

Edit: To whomever marked this as "Not Helpful"...do you just not like me? I don't get any more helpful than this.

Write speeds suck.. I just got 110/55 on a crappy microcenter 32gb flash drive.. although write eventually slows to 30, read is solid 110. I want to see usb 3.2 type a with 300 to 500 read/write... These chips were supposedly coming in micro sd format, it should be infinitely easier in usb flash.

The technology for this size of usb flash drive is totally obselete and can't compete with NVME, much less mSata m.2 drives. If you want a fast portable drive as small as possible, best bang for buck is the smaller form factor mSata (mini sata) drives with external USB-C enclosure. A 256GB one runs about $40, the enclosure is $20 or so. For USB-C 3.1 Gen 1 enclosures (which most of these are, 3.2 Gen 2 is not as common yet) the theoretical max speed is 5gb/s, or 625 megabytes / second, in practice 500 MB/s.

Next gen microsd and usb flash are supposed to incorporate m.2 specs adapted for their respective interfaces. This should be in 512gb/1tb cards coming next year. Microsd currently maxes out at 150-200MB/sec and usb about 300.. the density will confirm/shrink to microsd and thumb drive sizes.

This is the cheapest option by almost 30 bucks, no matter the speed. If you want speed you pay the premium, just like with sata and M.2 drives. You still cant put a SSD internal drive on a keychain, so these are not obsolete yet.

At this price range and capacity, although bigger, I would rather buy a portable SSD.
Faster and more reliable.
