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.

The ylmrav 256GB Smartphone and PC OTG SSD USB Drive comes with both USB-C and USB-A interfaces. The unit has a metallic constructions, which makes it sturdy and also helps with heat dissipation. This ylmrav 256GB SSD USB Drive works with several platforms. I tested it on several devices with Android, MacOS, Chromium and Windows OS. Since it has dual interfaces, I did not have issues switching from devices to devices without the need of an adapter. The ylmrav 256GB SSD USB Drive reached the advertised speed of 550 MB/s read speed and 501 MB/S write speed on a synthetic benchmark. On Windows it reached 513 MB/s write speed and 554 MB/s read speed over USB 3.2. Even when it reached 98% capacity, it was still reaching 400 MB/s write speeds. The ylmrav 256GB SSD USB Drive performed very well when connected to fast interfaces. On a Macbook Pro it reached 486 MB/s read speed and 456 MB/s write speed. On Android devices it reached a max read speed of 440 MB/s and just only 215 MB/s write speed...because it was an USB 3.0 interface. The ylmrav 256GB SSD USB Drive is a fast USB even when almost full. It is a nice USB drive to have when you need to move files fast.

I ordered this USB drive because I occasionally have to swap large video files with clients via USB drive. One client has a newer PC but it has only USB-A type ports. I wanted a USB-C drive that I could easily use on my new M1 MacBook Pro that would also work on my clients USB-A ports on his PC. This USB drive fit the bill as it has both USB-A and USB-C connections. When I opened the box I was very pleased to find that the USB drive has no logo on it to mar the plain silver color zinc alloy metal. It looks and feels like a quality product. I plugged it in the USB-C port of my 2021 M1 MacBook Pro and opened Apples Disk Utility app to see what file system it was formatted with. I was glad to find that it was formatted with the exFAT file system. This is the one I prefer because it works with both Macs and PCs and allows file sizes over 4GB. You could always format to a different file system, but this is the one I needed and would be most useful for the largest number of people. Most shouldnt even have to think about this. I next did a speed test using the Disk Utility app. Speeds were decent, showing almost 300MB/s read speed and about 400MB/s write speed. However, the speed falls significantly short of the 500MB/s speeds claimed in the product listing. Its In the multiple tests I ran, it was 20%-40% slower than claimed. Using BlackMagic disk speed test I got results about 10% faster than Apple Disk Utility test. This speed test is optimized for larger file sizes used in video editing. I got average readings of about 330MB/s read speed and 440MB/s write speed using this disk test. This is still not exactly the 500MB/s claimed but its a bit faster than the other speed test. The speeds are definitely due to the USB drive itself as Im using it on a new Mac with 40GB/s thunderbolt 4 ports which are capable of speeds almost 100x faster than the top speeds I got with this drive. For many uses this isnt much of an issue. These are still fast speeds compared to USB 2.0, but if your work requires transferring huge video files like mine does, youll probably want to know that it may take you up to 20% to 40% longer than youd hoped.

There are two sides to the drive. The smaller connection has a cool hinge design that allows the top to be removed and stay out of the way without losing it. The regular USB end just has a removable cap, which is also called a losable cap. Why in the world would the same hinged cap not be used on both ends? Thats frustrating to me because I will 100% lose this little cap. I know, its in the product description, but I just assumed there would be some sort of cap retention like a small tether or something. For that reason alone, I am hesitant to use this drive. But it works great as far as portable drives go.

works & looks great!

Just as advertised and as a rather skeptical person, I found it much nicer than I was expecting. I knew in advance it is a rather large drive, yet was not expecting such a smooth well designed case; an impressive design using a solid feeling alloy which likely helps disperse heat too. The drive is extremely fast and comes pre-formatted as exFAT with 238 GB of available space according to Win11. I tested it with AJA prior to reformatting, and it returned great results; 475 write & 510 read using USB-C. My requirements for this required it be formatted as FAT32 which was done with Ridgecrops FAT32 Formatter. Typically Windows cant format drives over 16 GB as FAT32, so if you have this need you will likely have to use a 3rd party tool too. I re-ran the speed test again, and although not as fast, it still returned great numbers (312 write & 505 read). If youre able to access it as exFAT I highly recommend you stick with that, for that does not constrain individual files to a 4 GB cap like FAT32 does. The cap that covers the USB side of this drive is held tightly in place magnetically which I really like. The cap on the USB-C side pulls off and swings out of the way so as not to be lost; both are well designed with a matching metal finish. Since I will mainly use the USB-C side, at first I wished it also had a removable magnetic cap. Though after some reflection I think the swing away design is probably better, for that cap will normally be off and Id be sure to misplace it. That said, most laptops will need the USB-C cap to be swung upward, or the weight of your laptop will resting on the cap; which would not be good for your port or the drive. I included a picture of it swung down on my Acer gaming laptop to show how it extends below the level of the laptop if it were not resting upon another laptop. This drive will spend 99% of its life connected to a 3-port USB-C hub being used by my Anker Nebula Capsule 3 Laser projector, and for that this is perfect. After loading it up with content it had no problem recognizing it and playing files thru Android TV without any issue of hesitation. The only thing that could make this better is for Anker to update my projector so I can go back to using this with exFAT; fingers crossed. I highly Recommend this drive, based on its reasonable price, solid design, large size and blazing speed.

VERY SATISFIED! Extremely fast transfer speed, lots of space. It cannot (physically) connect to my phone with a larger case, but will on my slimmer tablet case. This allows for easy transfer, compilation, and storage of files from many kinds of devices not just laptops/desktops like other USB storage. For the above reasons, I think this is almost perfect. If it had a narrower neck for the USB-C port, it would be 6 stars and not just 5.

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

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.

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+++
