SanDisk Ultra Dual Drive Go USB Type- C, Lavender, India, 400MB/s 256GB, Mobie Pendrive

The read and write speed is good , but the plastic quality is poor . And also it gets too heat in minutes. But it is a nice product in this prize range .

The sequential read speeds for a 8gb video file (after reformatting to exfat file system) were 157MBPS constant for a 8.7GB video file

Note- 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 above

The 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

The pen drive is very handy and functional because it works on both USB. very easy to use with mobile, computers and iPad. Speed is also good.

Totally worth it.
Can be used for both phone and laptop.
It also allow data transfer in iPhone 15 pro.
