SanDisk 256GB Ultra Fit USB 3.1 Flash Drive - SDCZ430-256G-G46, Black

still in box, keep forgetting to use it for backups.. im sure it works fine though. sandisk is a solid brand.

I have over 400GB of videos. I would normally steam them to TV but the TVs Wifi broke. So, I decided to put them on a 512 GB USB flash drive and plug it into the TVs USB. Heres what I found... 1. A 500GB SSD shows actual available space of 465GB after formatting. This 512GB USB flash drive only has 460. Thats a shortage of 17GB. 2. After copying about 410 GB of videos, the SSD shows about 56 GB available. That adds up to 466 and matches its capacity. After copying the same videos to this 512 GB flash drive, it shows about 13GB remaining. That adds up to 423GB and very inefficient. I formatted both in Windows 10 as NTFS with recommended allocation unit size. 3. The copy speed/performance is terrible. It took 2:25 hours overnight to copy the 410GB. In comparison, I copied about 61GB to my 2TB Samsung SSD over the same USB port in about 4:35 minutes! That would be about 31 minutes for 410GB (not 12 hours). Bottom line... if you need convenience and small size, this is good. It is also easy to lose! If you want speed and efficiency, look for external portable USB-C SSD.

Funciona a la perfeccion, lo utilizo para almacenar mis archivos

There is a reason I spend more money for a SanDisk drive. It works. I have never had a problem with SanDisk. I did go cheap once. I quickly returned to SanDisk.

I will be making future purchases of this product.

Great price, fast, small and easy to use. What more can you expect from a small thumb drive.

This flash drive is almost to small. Amazing what it’s packed with

Dont sync to much. One by one it great.

The product is good but the durability is bad as you can see in the photos the USB flash drive banded, easily. made with really thin plastic.

The capacity and speed are fine. Whats not good is the oh so thin plastic casing of the drive. Its cracked open and almost broken away. Not good Sandisk!
