Bests & Worsts Reviews from Amazon

This SanDisk 32GB CZ43 Ultra Fit Series USB 3.0 Flash Drive (SDCZ43-032G-G46) is so tiny, it makes my old SanDisk Cruzer Micro USB drive looks like a dinosaur! See the picture I uploaded to 'Customer Images' section for size comparison. www.amazon.com/gp/customer-media/product-gallery/B00LLER2CS/ The new drive is also 5-10x faster. On the package it says "Speed up to 130MB/s". This claim is valid based to my testing. I used a benchmark program (CrystalDiskMark v3.0.1 x64) to measure the Sequential Read/Write speed of this Sandisk Ultra Fit flash drive on two computers. Here are my findings: - When connected to a computer with USB 2.0 port: Sequential Read = 34.8MB/s, Sequential Write = 18.6MB/s - When connected to a computer with USB 3.0 port: Sequential Read = 148.4MB/s, Sequential Write = 39.4MB/s (see the pictures I uploaded to 'Customer Images' section for details) The above shows that this flash drive's Read speed is even faster than advertised. But you must use it on an USB 3.0 port to unlock its full potential. This is because the old USB 2.0 port has a theoretical speed limit of 60MB/s. In practice the highest I have seen is just around 36MB/s, as in this case. Other notes: 1. The capacity of this '32GB' drive, as reported by my computer, is only 29.8GB. This is actually normal because computer people count one Gig as "2 to the power 30", which is 7.3% greater than one billion. So 29.8GB comes to 31.99 billion bytes, which is called '32GB' by marketing people 2. The 32GB version of this flash drive is formatted in FAT32 for maximum compatibility. But the file size has a max limit of 4GB each. The 64GB drive is formatted in exFAT, which allows larger files. The problem is that exFAT may not be recognized by older computers and appliances. So suppose you want to plug the 64GB flash drive into your TV to play movies, make sure the latter is compatible with exFAT. 3. There is a small hole on this flash drive for attaching a lanyard, but none is provided. It is a good idea to find a lanyard - before the tiny drive got lost. 4. The drive does become warm when plugged into the USB port. This is normal and there's nothing to worry about, since all computer-grade electronic components are rated to at least 85 degree C ambient temperature.
