Thumb drives are still getting larger & larger every day, but this 256gb size is a really great size now in my opinion for PCs & Macs or phones with USB-C. Big enough to hold quite a few HD 1080p & even 4k movies & shows, or just tons of various files but not SO large that it breaks the bank! This drive is neat. VERY well made & its USB-C OR USB 3.0 whichever you need or prefer. Transfer speeds were lightning fast & steady the whole way for very large files through the USB-C port and still good & stable through USB 3.0 but the speed did drop off a good bit through USB 3 on large transfers. No drop off at all through USB-C. USB-C speeds were nearly 400 MB/s from my internal SSD to this drive. No noticeable heating up of this drive either. One of the better flash drives Ive had in some time.

Im so glad someone made this device! My phone has so many pictures and videos on it. I wanted an easy way to save them and this is a very easy way to do so. If you have a case on your phone you may need to remove it. I plugged this into my Galaxy 10+ and it mounted with no issues. Transferred all my videos and pictures fairly quickly. Just make sure to unmount the device before removing it from your phone or your phone will freak out and want to be rebooted.

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.

This USB flash drive came in a fairly nondescript black box, with no branding on the box or the USB drive itself. I tested with a few different utilities, and it does appear to have 256GB storage. In addition, my speed tests show that it does come close to the 500MB/s read AND write speeds, as advertised. The flash drive itself has a little bit of heft to it. The cap for the USB-C side is not removable and has a swing mechanism design. The cap on the opposite side for USB-A is removable but is magnetic which makes for a satisfying connection. I used both connectors to connect to multiple PCs, Android phones and tablets, iPad Pro, and a MacBook Air with no issues.

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!

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.

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+++

This makes it a very convenient and versatile device for people who are always on the move and need to carry their files with them. It also features SSD technology, which provides faster data transfer speeds and a more reliable performance than traditional hard disk drives. This makes it a great option for users who need to quickly transfer large files, such as videos, photos or music. I tested by transfer about 200Gb of large files (each file approximately between 2Gb to 8Gb), and the average transferring speed was around 85Mbps, which is great for these portable flash drive. Overall, the 256G Smartphone and PC OTG SSD USB Drive is a great device for anyone who needs a convenient and reliable way to store and transfer their files. Its also great for people who need to transfer files between multiple devices, its small and portable, easy to use, with fast transfer speed and a large storage capacity

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.

works & looks great!
