Ultra-fast performance lets you transfer a full 4K movie to the drive in less than 10 seconds, or 1000 photos in less than 20 seconds. Due to the conversion of 1GB=1024MB,display capacity of a 512GB drive usually appears at around 90% on Windows due to algorithms differences in which 1GB is interpreted as 1024MB on Windows and 1000MB on USB drives.

Whether the product is compatible with IOS？ Thank you for your question and our SD301 is compatible with Type C and USB A ports.If your IOS device is with a lightning port, It is not compatible with our SD301.If your IOS device is with type C port, our SD301 can compatible with it well directly.Please follow these step as follow. Step 2:Connect the C port of your iphone/macbook/ipad ,and find whether there come out the " SSK Drive " folder or not. Please note: Due to the IOS limitation, not all files can be opened by its system, SSK Drive is only the storage device, if the apple device you are using does not support the file, then our SD301 will not be able to open this type of file either. Is it normal for the product to heat up during use? This memory stick is a portable solid state flash drive, the speed is faster a lot than ordinary flash drive, and it is made of metal shell, which has better thermal conductivity , so that the heat will be much more than the ordinary flash drive. Your hands may feel a little hot, but this is normal. This situation will not affect your use, nor will it damage the data. Our products have gone through a series of sophisticated tests, which is safety enough in normal using. Why can't SD301 be recognized on a smartphone? How to solve it? First, please go to check the flash drive’s format, please make sure it is EXFAT, if it is not EXFAT, please format it first (Before formatting, please backup all your data); Second, please go to check whether the OTG function is enabled, most of OPPO's mobile phones need to manually open the OTG function. Only when the OTG function is enabled, the data transmission of external devices can be carried out. So you need to turn on the OTG function of your phone. The details can be found on Youtube. You can search for "How to Enable OTG Connection on OPPO Developer Options" on Youtube. Why does the write speed of SD301 drop when I write to large files at once? Writing large-capacity files at one time,the write speed will decline is a common problem of most solid-state drives. Even solid state drives produced by well-known companies also have this problem, which is a technical problem, not a problem of our product itself. If you want to maintain a high write speed, it is recommended that you do not write more than 1/4 of the remaining usable capacity at one time. For example, when the USB SSD drive has 600GB available capacity left, you can transfer data less than 150GB at a time, the speed will not drop.

Review: Like it - Very nice and fast. Plenty of room for what I need it for, transfer between desktop and laptop. Simple to use both ends. Transferred 1.2 Gb in seconds, 40.5 Gb from another external slower hard drive in about 4 minutes. Fast enough for my use. Plus the case is a nice touch. Built solid.

If you need a fast, high-capacity flash drive that works with both modern USB-C devices and older USB-A systems, this is an outstanding choice and offers excellent value for the money.

### ⭐⭐⭐⭐⭐ Tiny and Mighty Flash Drive
*by M***O on October 19, 2024*

Tired of those average flash drives... Yes! The ones with limited space and take forever to transfer all of your files? Say no more! With its 128GB to 1TB capacity and USB 3.2 Gen 2 interface, which offers read and write rates of up to 460MB and 360MB, respectively, the SSK External Flash Drive completely alters that. It's ideal for on-the-go use because it can be slipped into your pocket or attached to your key chain. This gadget is incredibly versatile, making it ideal for storing and playing documents, videos, and images in one location. Overall, this should provide consistent performance, while some people may discover different to comparable results. Several people have mentioned that this drive becomes hot, but exactly how toasty does it get? In the last two images, I recorded the base temperature 5 minutes after first plugging it in, which was 32°C. Then, I thought it wouldn't have made sense to take recordings of the tempture during the first test, so I ran two full tests with 9 runs per each SEQ (SEQUNTIAL) and RND (RANDOM) read/write of the 16 GB as a drive burner, each test taking about 10 minutes. During the second test, I recorded the temperature at 51°C which was its peak but hovering more around 50°C. However, in just a matter of one to two minutes its already cool due to its Zinc alloy outer coating. If your worried about the dual USB A and C ends not having the same speeds, have no worries! I ran both ends into the back end of my B450-F Gaming Motherboard which has USB A and C 10Gbps ports. The speeds have about 1% deviation in speeds if none at all since these tests aren't perfect, meaning the storage chips are slower than the interface so for complexity reasons in this review I've chosen to keep it simple. For anyone in search of a reliable pocket-sized device that offers both high speeds and large storage capacity, this is definitely the one to consider. Its performance is unmatched, providing fast data transfers and handling demanding tasks with ease. Whether you're backing up large files, running high-capacity tests, or need quick access to your data on the go, this device delivers consistently. There are virtually no alternatives on the market that offer the same combination of speed, durability, and storage in such a compact form. It's a game-changer for those who need portable, high-performance storage.
