Additionally, the Silicon Power Marvel M70 is backwards compatible to USB 2.0. This means that if your USB port on your computer is not blue in colour, then you can still use the drive. You will just receive that annoying notification from Windows letting you know that the drive can perform faster in a USB 3.0 port. If your computer is not equipped with the latest USB technology, then we encourage you to have a look at our report of the HighPoint 4-Port HBA. This PCIe expansion card easily allows you to add four additional USB ports to your system, as well as the addition of USB 3.0 technology.


When you purchase the drive, you also get access to a free download of the SP Widget, which provides you with seven bake-up and security functions. You also get access to Recuva File Recovery, which lets you try to recover those lost, deleted files.

Thanks for that. Can you check if flash is TLC or MLC ?

Pro tip:
You guys at tssr should use chipgenius for every flash product you review. It gives out controller and flash information, which is always a nice thing to know 🙂


this flash memory speed is between 60 untill 70 mbps so TLC can not give this speed by ps2251-03 and ithink for usb memory conteroller phison and siliconmotion and etron is better than another conteroller

You can always check with chipgenius to be sure.
