    Good reliable flash drive. I like loading things onto my flash drive and deleting them from my computer so that I still have them saved if I need them, but it doesn’t slow down my computer ! If it’s something super important, I would back them up on 2 flash drives though, just to be safe! I have had one malfunction on me before

    I used to buy Corsair USB drive for more quality but it gave me a lot of disappoint. However after I bought this, until now it gave me great experience with its performance and stability. Its quality is so great.

    I use various flash drives to back up my pictures in addition to backing them up on my external hard drive. 128GB seems to be the sweet spot for price versus capacity.

    Great flash drive! Just as advertised. No light indicator like some others do, but really not missing that. Ordered one for home a month after getting one for work and using it daily. Highly recommended.

    works great once you reconfigure it

    It reads very fast but writes much slower than it should considering it is a 3.0. Unless you reconfigure it it will not copy large files which is the main reason to buy it.. to reconfigure it - right click, select format it will state exFat (default) open it and select NTFS - select allocation size as 4096 bytes save it and exit. Now you can use it to copy very large files.

    Fine drive, weak closing latch

    This reviewer received promo considerations or sweepstakes entry for writing a review.

    While this is a functional flash drive, the closing latch does not engage effectively and the USB connector can become exposed unintentionally. While this is not really a danger, it is a bit of a nuisance. Otherwise this is a fine value for a 128gig flash drive.

    No, I would not recommend this to a friend
