Tuesday, March 28, 2017

The easiest way to upload and download data between memory cards or to your computer is via a card reader!

The multi memory card reader is one of those nifty gadgets that really come useful, especially when your laptop or computer doesn't have built-in memory cards.
The ASUS ROG G751J does have a built-in memory slot for a SD card, but the USB 3.0 multi memory card reader by AKASA comes handy for increasing memory card reading functionality.
In total, you get four memory card slots with Akasa's USB powered multi memory card reader, including one microSD card slot, a SD card slot, a CF card slot and a MS card slot.
SD stands for Secure Digital, while CF and MS stand for Compact Flash and Memory Stick respectively.
Compact Flash is actually the oldest form of removable flash memory format, being released in 1994, closely followed by the Memory Stick (released in 1998), Secure Digital (released in 1999) and Microsd (released in 2005). I actually remember the microSD's original names which were T-Flash and TransFlash.
Dimensions 80mm x 56mm x 18mm 

compatible with USB 2.0 and USB 1.1
Akasa's USB 3.0 multi memory card reader supports all capacities of SD cards, including SDSC (1 MB to 2 GB), SDHC (2GB to 32GB) and SDXC (32GB to 2TB).

Akasa's USB 3.0 multi memory card reader is also SDHC/SDXC UHS-II compatible and supports SD 4.0 specification, which means you get can get read and write speeds of up to 500MB/s when connected to a USB 2.0, and up to 5Gb/s when connected to a USB 3.0 port.

As you can see from the video above, the multi memory card reader is hooked to the ASUS ROG G751J laptop and the file transfer rate is fairly fast to the SD 512MB Ultra II memory card. Cross transfer data between memory slots is also possible thanks to simultaneously active card-slots.
USB 3.0 A to Micro B Cable included

Memory Stick card types include MS Pro, MS Pro Duo, Magic Gate, Extreme and Ultra. Compact Flash card types include, CF I, CF II, Ultra, Extreme, I-Pro, Ultimate and MD.
