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

Drive would not accept 6gb. 5.7gb video file. Smaller files (1gb) no problem. See future headaches w this contriction. Other 256 usb drive I purchased worked fine.

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.

Very small, attractive package with rounded edges and big storage capacity. To think how much memory devices have improved! Comes with useful vault password-needed software to protect files. Two thumbs up.

This multi-pack provides very good value and this small size and product package makes it very easy to add to keychains and tie-wrap to other items

Good

To have this kind of storage in such a small package is a tremendous convenience. I have a 512 GB version of this andc it has petrformed perfectly and takes up virtuall no space in my car. Sandisk has always produced an exceptional product and these flash drives are definitely in that category.

No issues with reliability, but I wish it would be bigger. Hard to handle as its so small. Otherwise a quality product.

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

Good and easy to use.

Very accurate
