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

I have purchased this item twice. I love how compact it is. I use it primarily for storing my photo RAW files so they dont take up space elsewhere on my computer. Great product!

This is my second time buying the disk on key 512 GB by SanDisk. The product arrives with about 50 GB less they are occupied for system files and background stuff. I noticed while transferring photos and videos that it is pretty slow lower to be precise slower than I expected it to be after running a few tests. I found out that my discount keys are running slower than advertised on the package and in the description. Overall I am going to be using these due to the fact that they still have a decent amount of storage for my usage and their size which is the biggest perk in my opinion.

Great product

You know, bring born in the first half of the 90s, you really get to see and appreciate tech blowing up. Mayne not as much as our parents coming from PDP11s and DOS. But a good amount all the same. I remember, as a kid when 56Kb was a fast throughput and 512MB was an acceptable USB storage size. What a time, an order of magnitude more storage is on a device a fourth of a regular USB. I recall having my desktop set up with a 20GB PATA drive and classic SCSI, not this new fast stuff. What a time. I am amazed everytime I plug this modern marvel into y system.

Fastened to a lanyard to prevent losing

This has proven to be an awesome little external storage device. I bought it in December and already have it filled up. 1 million times better than a big heavy pain in the foot external hard drive!!! Zero problems.

Great for music storage

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.

For the price, it is an excellent buy. My only issue Ive had with it in the time I have used it is that I cannot copy a single file larger than 4 gigabytes to it. For example, I attempted to copy over a 7 gigabyte MP4 file from a streaming session, and my system told me it was unable to move the file because it was too large. Keep in mind that I have only used 20% of the space on this 500Gb drive at this time. With that said, the times I need to use this drive for a file of that size are very rare, so that is not a deal breaker for me. I mostly use this as a backup drive for my files after all. All in all, great buy. But if you need to use this for very large files, you might instead need an external drive rather than this.

Purchased two of these 512GB Ultra Fit USB 3.1 Flash Drive. Unpackaged both USB Drives and added them to my laptop. BOTH DRIVE SPACE ONLY = 460GB each!!!! << NOT EVEN CLOSE >> NO ADDED SOFTWARE ->> >>> 52GB SHORT per-USB Drive. -- TOTAL LOST Drive space = 104GB. You need to do better SanDisk!
