    I ran across this article which explains the different USB Flash Drive NAND types.


    It is my understanding that all of the current "budget" USB Flash Drives use the cheaper and slower TLC NAND.

    I found that the Muskin Ventura & Ventura Pro have the MLC NAND. Many of the manufacturers don't list the NAND type.

    There are some very expensive lower capacity (up to 8 GB) "Industrial" USB Flash Drives which have the SLC NAND.

    I looked into this because of my concern about Maximum "Write" cycles.

    I guess if you are going to use a USB Flash Drive much, it would be best to go with a mid-priced USB 3.0 Flash Drive such as the Muskin Ventura or Ventura Pro (Faster Read/Writes and "Theoretically" longer Flash Drive Life).

    I no longer see MLC NAND listed on Muskin's website for their Ventura & Ventura Pro USB 3.0 Flash Drives. I also have noticed significant price drops recently on these models. I guess that implies that Mushkin 'may' be using TLC NAND now, but I do not know for sure.

    Most SSD drive makers are using MLC NAND type for their SSD's.

    For usb flash drives the cheaper TLC based NAND is used. This is the reason for their slow transfer rates of around 15 MB/s.

    Your quoted Mushkin is most likely using MLC as the transfer rates are 120/70 MB/s. I am assuming it is quite expensive too as MLC based NAND is expensive.
