Review: Great Storage Media! - I only use Sandisk USB Ultra Flair drives, maybe a Cruz here and there. Never had any problems with them, rock solid. They do get fairly warm, being so small. Really warm. But it doesn't seem to affect them at all, as I've have some going on 4 years now. Good storage at a good price.

## Questions & Answers

**Q: Number of reviews mention this flash drive getting hot rapidly. Is this listed item an upgraded version which addressed that issue?**
A: My USB drive got extremely hot and seriously lagged my computer.  This is due to I/O hangs due to bad memory locations in the flash devices which is totally normal.  At this amazingly awesome price point, the factory is not formatting it.  So all you have to do is format the drive (over night).  I had a house fan blowing on it during the format.  Now the drive is slightly warm when doing a full backup and lags my laptop not.

**Q: Does this drive come with a cap (cover)?**
A: No cap - it is one piece -no moving parts nothing slides in or out no cap it just plugs straight in to the usb port as is

**Q: What is the writing speed? i want to run alternative operating systems on usb like remix os and linux distros. i need at least 20 mb/s writing speed.**
A: I have the 128 GB and the 16 GB. Both tested on several computers. At larger file transfers the writing speed goes down to 5 MB/s and even stops completely for some time. Desperately I tried all Windows file systems - there was pretty much no difference. I have so many SD cards and sticks - this product has the worst write performance I have ever seen.

**Q: Does it have an LED light?**
A: It has not led light.

### ⭐⭐⭐⭐⭐ USB 3.0 flash drive
*by J***E on January 22, 2026*

This SanDisk flash drive is a reliable device for everyday storage. The sleek, durable metal housing feels solid in hand and easy to carry around. The read and write performance of this USB 3.0 is fast, ideal for the storage of movies and backup files. USB 3.0 is faster compared to USB 2.0 devices. It's also fully backward-compatible with USB 2.0 ports, but will operate at reduced speeds on those older ports. The connectivity to a USB 3.0 port or higher can achieve significantly higher throughput, which speeds up transferring large files like videos, photos, and backups compared with older USB standards. Some flash-drive lines come in multiple colors, this flash drive focuses on this metallic black/silver styling. Overall, it's a solid, budget-friendly choice for extra portable storage.
