What is the real space available for the user? i Need at least 230GB free...

On mine, after reformatting to Apple's HFS+ journaled file system, I had 248,125,304,832 free bytes available. The raw capacity was 248,437,014,528 bytes.

Anyone had this for 3-5 mos or longer and still happy with it? Still working well? Thanks in advance!

Works perfectly and fast. Nice even loading between 21MBPS & 31 MBPS. I t settles in evenly somewhere between these numbers and loads in almost the exact number all across the (in my case) music until they are are all loaded. In my case about 28MBPS. I use NTFS file format. Perhaps exFat may be a little faster of slower, I haven't tried it as It was fine and I didn't want to format the drive just to find out. I did a fast format at the start to leave the drive completely empty as I didn't need locked security. I am 'assuming' it works as advertised. Playback was flawless. Function fallowed fit which was just right from Rxer, to car, to PC. No sloppiness or 'collapsing' when inserting drive. I've found all Sandisk's to be well made, and most important, reliable, for years but this specific model has very little heat build up and 'all in all' is the best I've ever used so far. The exact opposite of a certain brand starting with a 'P' which runs hot and is guaranteed to eventually fail and the loss of about 5600 songs can be devastating. Getting the songs to run in the exact same order as recorded on the CD is a continuous problem and I haven't figured out yet to set that and all USB's seem to do it. I'm fairly sure there is a way but I haven't found the exact way to do this on any brand. Suggested solutions gratefully appreciated. Aside that, this is a winner and at $11.99 new, a very good deal. A year+ so far and no problems, Paul

Does it read as a hard disk drive or removable storage when plugged in?

Removable storage. Unless you use it as a Windows To Go drive, when it would be read as a hard disk drive.

Very Good Product.. But EXPENSIVE..!!

The product is very good... as is the quality of all SanDisk products. However.. the pricing should be more reasonable.

Nice pendrive with good reading/writing speed but storage space is only 230gb which is very bad.

I recently purchased the SanDisk Ultra USB 3.0 256GB Flash Drive, and it has exceeded my expectations. With a huge 256GB capacity, it’s perfect for storing large files, videos, documents, and backups. The USB 3.0 interface delivers fast transfer speeds up to 130MB/s, which makes moving files quick and hassle-free. The build quality is solid and durable. The drive feels sturdy and compact, making it easy to carry around without worrying about damage. I also appreciate the added security features—password protection helps keep my data safe, and the RescuePro Recovery Software is a lifesaver in case files are accidentally deleted. It’s plug-and-play, so setup is straightforward, and it works seamlessly on Windows, Mac, and other devices. I’ve been using it daily for both work and personal files, and it hasn’t failed me once. Overall, the SanDisk Ultra USB 3.0 256GB is a reliable, fast, and durable storage solution. It’s perfect for professionals, students, or anyone needing a high-capacity, high-speed flash drive. I highly recommend it for anyone looking for a trustworthy USB memory stick that delivers both performance and security.
