Differences between cool USB Flash Drive vs. SD Card

Differences between cool USB Flash Drive vs. SD Card

The storage devices have always held a special place in the digital world. I still remember the days when the only portable medium of computer data was a floppy disk, and how irritating a task storing those disks was. Then came the CDs those were later further improvised as DVDs, but the portability still remains an issue for users like me, who don't like to carry around large handbags or covers while commuting and even wasting the precious shelf space, to store those thick CD/DVD organizers. 

The introduction of flash storage device came as such a big relief to users like me, who actually make a larger section of computer users. Since the flash memory technology was first invented, a lot of development has happened in the area, and storage devices itself have evolved in the much dynamic array of offerings.

Here, in this article, we are going to compare two most popular storage devices, which basically operate on the same NAND technology – Cool USB Drives & Secure Digital Cards (SD Card).

A flash drive is popularly known as, USB flash drive, Pen drive, USB stick, Thumb drive or a USB Key. Since it was first made available in markets for the common users, its storage capacity has rapidly increased and the prices have gradually reduced. At present they are available in storage capacity ranging from as low as 2GB up to 256GB.

The major user-friendly feature of a Flash Drive is its standard application. What I mean by that is – you could plug and access a flash drive to any device that has an USB port. Though the recent advancement in USB port is the arrival of USB 3.0, but it's said that the manufacturers will continue providing devices with USB 2.0 compatibility to make sure the existing drives, which is available in the market and with users to an unimaginable extent, do not become redundant.

The biggest advantage of USB 3.0 is a much higher data transfer capability; after all, we are so used to getting everything at a lightning fast speed, so why not desire the same of a USB as well?

Another interesting feature of a flash drive is the customizability of its outer body, they are designed in a most creative way to match the fancy of its user, be it a fish pout or a forward-looking sleek metallic stick. These cool flash drives are fun to carry around, and of course, the portability is unbeatable.

SD cards, on the other hand, are also built on the premise of NAND architecture. SD cards are an integral part of any device that demands rich multimedia storage, like cameras, mobile phones, music systems or gaming consoles as popular applications. Unlike USB flash drive, they do not come in one standard plug size, they are sleek chips of semi-rectangular shape, that come in different sizes. Broadly, SD cards are manufactured in four families, with three variations in each family. They are – Standard Capacity, High Capacity, Extended Capacity and Standard Input Output (SDIO). The three variations in the size are – Original, Mini and Micro. The compatibility of the host device to these cards could vary, but most sizes could be read using an external SD card reader.
