Customer Ratings & Reviews

Disappointing, but adequate for moderate speed writes. Tested with Ubuntu Linux 14.04.2 on Sony VGN-NW270F using default Disks utility. My computer has USB 2 ports. Benchmarking parameters:: Transfer Rate Samples = 100, Sample Size = 10 MB; Access Time Number of Samples = 100. Results:: Averages: Write = ~12 MB/s Read = ~39 MB/s Comments:: Reads were fairly constant at ~39 MB/s with insignificant fluctuation. Writes spiked sharply between 12 and 7 MB/s. Access times were constant at ~0.99 ms. Conclusions:: I have a few PNY flash drives of the same capacity, purchased recently, that benchmark about the same on read and access, but are twice as fast on write. The waveform on the PNYs are square and may contribute to the better write speeds. The SanDisk had sharp points on the top and bottom of the waveform. I'm not an engineer, but I suspect the controller in the PNY flash drive may be more modern and advanced than the one in this specific SanDisk flash drive.

I needed a new USB Drive, this one is fast and reliable, I installed a usb toolkit for pc troubleshooting and it works perfect

It works as expected. I got what I paid for and it’s fine. The only thing I don’t like is that it opens without warning if your attaching it to a keychain.

SanDisk - Ultra 64GB USB 3.0 Flash Drive has been so great for my son saving space on his PS4.

This memory stick worked well. The only time it had issues was when connecting to the USB port on my router for file sharing over network. Sometimes the stick would not be recognized - I suspect the router is to blame there.

Very happy with the SanDisk thumb drives. I have purchase several of these and all have performed well. I do recommend the USB 3.0 as the transfer speeds are noticeable faster.

The product is as it was described and at a reasonable price. It is a convenient way to back up files.

I recommend this flash drive because it is easy to use and convenient to carry in my bag.

Perfect to keep important files backup....plenty of space to include irreplaceable photos. Good price.
