This drive is as advertised. I tested it in Crystal Disk using the usb-c connector in a thunderbolt 3 port and got exactly 500 MB/s write and 547 MB/s read - so significantly faster than any typical usb flash drive, but obviously not up there with an external nvme drive which test at right about 1000 MB/s on the same thunderbolt 3 port.

These devices are great and this one in particular is really fast. It reads and writes at around 500 MB/s (average) which is good enough for me. The capacity is quite good at 256GB. But you should remember not to keep filling it full and then deleting everything. The more that you repeat a fill/delete cycle - the quicker the USB drives life will expire. Fast USB drive at a reasonable price 37 bucks. Super Fast USB Drive. HIGHLY RECOMENDED! AAA+++

I still need to run around with removable media, and came across this Ylmrav 256Gb Smartphone and PC OTG USB Flash Drive, and thought I’d give this a try. It comes in a nice presentation case with very nice padding. It has a nice brushed finish so there’s no issue with fingerprints. It has caps to protect both ends... the USB-A connector, and the USB-C connector. The caps are awesome! For the USB-A end cap it is MAGNETIC. Which means it won’t come loose until you pull on it. The USB-C end swivels out of the way and is also magnetic. I have no concerns that I’ll lose these end caps. I have some specialized utilities, and I did a 13 hr reliability test, where different size data chunks are written to the entire disk in three iterations. No issues whatsoever. On a standard USB 3.0 connection, data transfer rates averaged 352 MB.sec. Sadly, I was not able to test transfer speeds under USB 3.2 protocols. In broad testing, USB 3.0 transfer rates were good. 1.55 GB in 10.6 sec 6.34 GB in 59.2 sec I have no doubt that USB 3.2 rates would be consistently faster. This flash drive just FEELS great too. It’s chunky and solid, and is built like a tank. This is a utility drive I’ll use over and over!

The drive is small, easily pocketable and fits in the small pocket of jeans. The product photos shows text printed on the drive but the drive I received has none, its a nice clean silver finish thumb drive. There is no hole for attaching a lanyard. The cap for the USB Type A port attaches to the drive magnetically. The drive casing and cap is metal so should be fairly durable. The metal also helps to dissipate heat when the drive is in use, it gets hot but not burning. When plugged into a Windows 10 PC, the drive was auto detected and already formatted. The drive is able to reach the advertised speed when used with a Type C port. The Type A port was slower but not by too much.

Super easy to transfer data from your phone to your computer. I took tons of pictures on my Samsung phones and I am able to just send them over to this card then I just plug this card into my laptop and move all the photos over. This beats all the hassle of plugging your phone into your laptop.

I picked this one up to replace a 128GB drive that I use with Ventoy. I had no issues reformatting and partitioning with the Ventoy tool and both Mac and Windows PCs are easily able to read and write to the drive. Several test systems booted from the drive, both USB-A and USB-C ports, with no issues. The drive is in a metal case and has a nice weight to it. The USB-C side has a swing-away cover and the USB-A side has a magnetically attached cover. Overall, super happy with this one.

Incredible. 256 gb of storage on a duo usb & usb c drive. Love this little thing. Packs so much power. First test was transferred a 10gb file within 3 mins. Loveeee 10/10 highly recommend

256G Smartphone and PC OTG SSD USB Drive, USB3.2 Type-C and USB-A Dual Connectors Solid State Flash Drive, 2 in 1 USB3.2 Flash Drive, Super High-Speed Type C USB Drive,ylmrav The flash drive comes attractively packaged in a gift-worthy box that is enclosed in shrink wrap. The only information on the outside other than the sticker identifying the product is a red sticker in the middle of a black field, noting that this is 256 GB. The drive itself is a metal cover on both ends, one with a magnetic closure, holding the cap on the USB3 connector, and the other is a levered fold-out cover on the USBC connector sideInsertinfing the drive into my laptop, windows recognized it immediately, and properties showed that there were 238 GB available and that it is natively formatted in the exFAT partition format. The decrease in available storage is normal with pretty much any storage drive because once its formatted, the formatting takes up a certain amount of space. I make a practice to reformat any flash drives that I use, just to make sure that the format structure is 100% and that there are no program fragments from any previous testing. Interestingly, enough, when I did the reformat, windows notes that this drive is natively an NTFS default structure, which Im going to format it to, and then format it back into exfat because that covers more types of storage systems. This drive should work well for my phone as well as a computer and will make transferring data between the devices easily done. Transferring some sample data from my laptop to the hard drive seems to move at a pretty fast rate, starting at about 300 megabits per second, which I think is pretty good. The metal cover is quite sturdy and gives it a good look. The magnetic cover on the USB3 side makes a secure ‘click’ when closing it, but there is no tether or place to keep the cap when the drive is in use, so you’ll need to take care not to lose or drop the magnetic cover [as I did, into shag carpet, making it a chore to find]. The levered cover on the USBC side folds out of the way for insertion and stays with the unit.

I ordered this to easily transfer files from my Samsung Galaxy phone. It works like a charm. I didn’t have any super huge files, but it seems fast enough for what I was transferring. It was easy to use and worked well. 256GB is a good size and can fit a large amount of pictures or files. The drive itself is well made. I do wish that both ends had the flip off but connected cap like the one on the USB-C end. That way one wouldn’t need to worry about losing a cap and keeping up with a small piece. I’m very pleased with this memory stick and would recommend it.

This drive comes in an attractive package. The device itself is nicely designed with a solid metal build and feel. The drive has two-end connectivity, one side USB-C with a swing open cover and the other USB-A with a neat magnetic cover. Performance was fast both for USB-C and USB-A. With many manufacturers starting to switch to only USB-C connectors for external devices, this external drive is a good choice for mobile devices, laptops, and desktops.
