SanDisk SDCZ43-O16G-G46 / SDCZ43-O16G-U46 / SDCZ43-O16G-M46 16 GB Pen DriveMulticolor

Filling up the drive full took 14 mins at the writing speed of 16.5 MBps. Taking out whole of the content took 2min 50 sec at the reading speed of 90 MBps. If you try to touch it when it is plugged in, It is just warm. However when you take it out in your hand, it is hot but it was never so hot that I couldn't keep it in my hands. Moreover it took just 4-5 secs to come to normal temperature. I tried the writing and reading process a few time and in 7/10 cases it was 19 MBps while writing and 100 MBps while reading data on my PC. In rest of the cases it was around 17 MBps while writing and 90-100 Mbps while reading. It is better than silicon power jewel series.

I always loathed tiny pen drives since they never deliver decent speeds. SanDisk Ultra Fit changes that. CrystalDiskMark results on USB 3.0 (FAT32, 5 runs, 1 GB): Sequential - Read 122 MB/s Write 11 MB/s 512K - Read 64 MB/s Write 0.6 MB/s 4K - Read 6 MB/s Write 1.5 MB/s 4K QD32 - Read 5.2 MB/s Write 0.37 MB/s CrystalDiskMark results on USB 2.0 (FAT32, 5 runs, 1 GB): Sequential - Read 33 MB/s Write 10 MB/s 512K - Read 29 MB/s Write 0.7 MB/s 4K - Read 4.5 MB/s Write 1.9 MB/s 4K QD32 - Read 4 MB/s Write 0.4 MB/s Pros: - Tiny - Stylish - Has a strap eyelet - Fast Cons: - Heats up considerably during operation (so far working fine though) - Easy to lose unless a strap is attached (recommended) - Write speed considerably lower than read, reduces usage scope Personally, I found this to be a perfect pen drive to keep OS installers (various Linux ISOs) on. You don't change those too often so write speed doesn't matter much but thanks to high read speed the installation takes very little time. However, it's not the best drive for tasks which involve frequent writing. You want to look at SanDisk Extreme drives instead then.

The product is good. Delivery was on time. The Delivery guy was very efficient and very polite. Good work Flipkart.
