The first thing I noticed when I took this drive out of its nice box, was that it was heavy! This is made out of metal; youre not going to break this on accident. Plugging it in, I saw that the drive already had Android system folders (empty folders) set up on the drive--this would make it easy for transferring/backing up files to the right places with the right names. As described, you can plug it into either a USB-A or C connection. Unfortunately, my phone case interfered with the USB-c connection and I had to remove it--but my case is quite thick. My disk properties showed 256G as expected. Im not caught up with the actual speeds (other reviews have commented on this) but it seemed to transfer quickly to and from the drive--it works for me. I would consider it a little pricey if it were just USB-c or USB-a, but its both--and its metal construction makes it a good deal.

I wanted to get this so I could easily connect my phone, pc, or mac to the thumb drive without worrying about needing a adapter. This has a ton of memory for me to store pictures, files, and videos on. It is also nice because I am able to connect my phone to this and transfer photos off of my phone to free up space. It is also a nice device to store videos so I can watch videos from this thumb drive rather than storing it on my phone. It will also work for thunderport on mac but you may need to format the drive in order to transfer to the mac. This is NOT a thunderport device so it will not utilize the full thunderport speed. If you are using it with your mac, it will transfer pretty quick to and from the device. This thumb drive is pretty decently built although the metal is a bit easy to scratch. There is no slot for key ring or lanyard which is a bit of a bummer. You are able to open the cover to use the type c port. The cap is connected to the thumb drive so it is hard to lose. The cap is pretty solid so it will not just pop off on its own. I do wish the USB port cover was the same. This is a pretty thick thumb drive so it may take up more than one slot. The price as well is pretty reasonable for a thumb drive of this size. The cap is nice because now there will not be any exposed plugs. The case is easy to get scratched up though. Overall this a good flash drive to have if you happen to need to empty your phone or even transferring data between devices via type c. Please note this is not a thunderbolt plug but it will work on a thunderbolt port. It has plenty of space so it can store a good amount of pictures. I do wish it had some kind of key ring slot as you can lose this drive.

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.

If you have large files then this is the USB for you! Fast file transfer and compact!

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.

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.

This just what I needed to transfer my pictures and documents from my iPad to my HP computer. I had to use a large adapter to transfer everything and it was frustrating going back and forth. This makes it much easier because it has two plugs that fit each device and it is small. The only thing about this is the drive in the iPad is buried within the system so I had to search for the drive. However once I found it, everything transferred beautifully. But that has more to do with the apple than the product itself.

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.

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.
