SanDisk Ultra Dual Drive Go USB Type- C, Lavender, India, 150MB/s 64GB, Mobile Pendrive

Perfect authentic quality product

The sequential read speeds for a 8gb video file (after reformatting to exfat file system) were 157MBPS constant for a 8.7GB video fileNote- the computer being used for testing has a pcie nvme ssd and a fairly modern and powerful cpu, but machines with a decent cpu and an average SSD ought to perform simillarly with usb 3.0 or aboveThe writes though, were a different story, as in the beginning for about 1.5 gb, the speed was 56MBPS, but then it dropped to 33, and it started throttling because of excessive heating.Difference between the go and the luxe- THIS IS WHERE THE ULTRA DUAL LUXE SINES AS IT DOESNT THROTTLE MUCH, BUT THE NORMAL GO DOES.The throttling occurs due to excessive heat generated, and because of it's plasticky build, it is unable to dissapate that heat, which can harm the NAND flash storage inside it; to prevent this, it reduces its speed and transfers in chunks of about 40MB before pausing briefly. It is a good thing as it prevents damage to the storage component, hence increasing lifespan, but at the cost of speeds. But after 33mpbs, it further drops down to 20, then 13 and becomes stable there. Here it's just too slow for heavy everyday use like transferring videos for editing. (Room temp 24C), your milage may vary with different types of files, computers and ports))But for the vast majority of users, who just use it as a backup, or for once in a while storage, or for regularly working with small files like pots and photos, it's perfectly fine. Its fast, makes it convenient to transfer files between phones and laptops and desktops, because of it's versatile setup of a changeable usb c and a setup. It feels strong and durable, even through its made if plastic.For the price of 719rs (for the 64gb variant) it is not very affordable. A regular usb a pen/flash drive and a type a to c adapter combination (as illustrated above, available for about rs 130 as of writing this review, and a 64GB flash drive costing anywhere between 400 and 550rs as of writing this review) will cost less. But a regular usb drive and the combo will not be as convenient and fast, but again it's not required for most people not to mention that the adapter is quite useful elsewhere as well; but for the small niche of users who want speed and have small files (below 1.5GB at a time) to work with, it's recommend.Otherwise going with the luxe (for performance) or the adapter setup (better value for money) as mentioned above will be a better decision.Hope you find this effort helpful

Very useful to transfer data from mobile to computer. Dual USB mode. Easy to use. Reasonable price. Sleek design with nice colour. Must buy for every media creators.

Excellent

The media could not be loaded. Not the greatest built quality. For just 100 or 200 rupees more, you get SanDisk luxe series, which is made of metal, I use that too, that has way better built than this. Buy that instead. Both works well incase of speed and storage, so that's good.

Size:- 128GB (115GB Available)Style:- 400 MBPSPrice:- Purchased for Rs. 1249Used it on PC:- ASUS TUF A15 (Ryzen 7 4800H, 16GB RAM, RTX 3050, 512 GB SAMSUNG MZVLQ512HBLU-00B00 with Sequential Read 3100 MB/s & Sequential Write 1800 MB/s)Speed:- The SanDisk Ultra Dual Drive Go USB Type-C has surpassed my expectations. During my usage, I observed remarkable read speeds of up to 327 MBps (equivalent to 2743 Mbps) and write speeds of up to 92.2 MBps (equivalent to 773 Mbps) while transferring a single file of 7 GB.Furthermore, when I transferred 102 video files totaling 17.7 GB, the device maintained a consistent write speed of 90 MBps, completing the transfer in approximately 3 minutes.Also, the speed with both of its USB Type A and USB Type C are the same. But before buying, check if your Laptop's USB supports 3.0/3.1/3.2 Gen 1/2 & that your SSD/HDD doesn't bottleneck the Pen Drive.Build Quality:- Its very light, it doesn't feel when you carry it in your hands. It's about as heavy as the NATARAJ Pencil Sharpener. Since it is made of Plastic, it doesn't get hot even after transfering files for 5-10 Mins. So, the speed remains constant at 350-370 MBps Read & 85-95 MBps Write.Compatibility: I’ve primarily used this device with my ASUS TUF A15, and it has performed flawlessly. I haven’t yet tested it extensively with other devices or operating systems but I think it will perform very good.Packaging and Delivery: The device was delivered in good condition, and the packaging was adequate to protect it during transit.Value for Money: Given its high-speed performance and the price I paid (Rs. 1249), I believe this device offers excellent value for money.In conclusion, this device delivers excellent performance and provides great value for its price.

I purchased this pen drive on 3rd December of 2024.It is good for backup and daily use but I gave it 3 stars only because I thought it was made of metal but when it arrived to my house I found that it was made up of plastic it also heats up after a certain period of usage also when some pressure is applied onto the pen drive its plastic bends that's why I gave it only 3 stars if its build quality is good I will give it 5 stars it also have very good transfer speeds for a cheap price for a pendrive

Awesome, must buy, works amazingly till today.
