[16GB] Review: SanDisk as SanDisk - All good, didn't check yet Review: Bigger storage in old design and spec - Operates at full speed, heats up after a minute of writing and then speed is reduced from 100MB/s to hovering 25MB/s. I only suggest it for the price and for making a occasional backup but the speed really puts it down. ## Features - Transfer up to 10x faster than USB 2.0 - Backward compatible with USB 2.0 - Secure file encryption and password protection with included SanDisk Secure Access software - Recover lost or corrupted files with a year’s subscription to Rescue PRO software ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00YFI1A66 | | Additional Features | Lightweight | | Best Sellers Rank | #6,660 in Computers ( See Top 100 in Computers ) #87 in USB Flash Drives | | Brand | SanDisk | | Built-In Media | Flash Drive | | Color | 256GB | | Compatible Devices | Computers, Laptops | | Compatible Phone Models | Laptop,Personal Computer | | Connectivity Technology | USB | | Customer Reviews | 4.6 out of 5 stars 20,548 Reviews | | EU Spare Part Availability Duration | 1 Years | | Flash Memory Type | USB flash drive | | Flash Memory Video Speed Class | V30 | | Global Trade Identification Number | 00619659125974, 07195003036446 | | Hardware Connectivity Technology | USB Type A | | Hardware Interface | USB 3.0 | | Hardware interface | USB 3.0 | | Item Dimensions D x W x H | 6.1D x 7.5W x 3.3H centimeters | | Item Type Name | SanDisk Cruzer Ultra 256GB USB 3.0 Flash Drive SDCZ48-256G-U46 up to 100MB/s | | Manufacturer | Sandisk | | Memory Storage Capacity | 256 GB | | Memory storage capacity | 256 GB | | Mfr Part Number | SDCZ48-256G-U46 | | Model Name | SDCZ48-256G-U46 | | Model Number | SDCZ48-256G-U46 | | Read Speed | 100 | | Reading speed | 100 | | Special features | Lightweight | | UPC | 619659125974 | | Unit Count | 1 Count | | Warranty Description | 2 year | | Write Speed | 80 MB/s | | Writing speed | 80 MB/s | ## Product Details - **Brand:** SanDisk - **Hardware interface:** USB 3.0 - **Memory storage capacity:** 256 GB - **Special features:** Lightweight - **Writing speed:** 80 MB/s ## Images ![Ultra CZ48 256GB USB 3.0 Flash Drive (SDCZ48-256G-U46) - Image 1](https://m.media-amazon.com/images/I/41Xtog9u8SL.jpg) ## Available Options This product comes in different **Size** options. ## Questions & Answers **Q: What is the real space available for the user? i Need at least 230GB free...** A: 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. **Q: Does this flash drive have a slider to retract the USB port into the casing?** A: Yes **Q: Anyone had this for 3-5 mos or longer and still happy with it? Still working well? Thanks in advance!** A: 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 **Q: Does it read as a hard disk drive or removable storage when plugged in?** A: Removable storage. Unless you use it as a Windows To Go drive, when it would be read as a hard disk drive. ## Customer Reviews ### ⭐⭐⭐⭐⭐ SanDisk as SanDisk *by S***. on 8 March 2020* All good, didn't check yet ### ⭐⭐ Bigger storage in old design and spec *by M***D on 24 December 2025* Operates at full speed, heats up after a minute of writing and then speed is reduced from 100MB/s to hovering 25MB/s.
