Now you should keep it in your mind that their differences are noteworthy, but they are hardly rivals in the world of NAND flash storage media. SD card vs flash drive :Īs you know now that they’re both small, portable, and used to transfer and store files. So, is sd card faster than usb flash drive? The answer on the question on sd card vs flash drive speed may vary from device to device. While most of the flash drives use USB 2.0, recently some newer drives on the market offer USB 3.0 with many times the data transfer rate or speed that we currently use. They can store anywhere between 128MB to 256GB of data. There are different types of flash drives. USB flash drives normally draw power from the computer via the USB connection. Mostly the flash drives use a standard type-A USB connection to connect to a USB port on a PC, but drives for other interfaces also exist. For example- The USB connector might be protected by a removable cap or by pulling back into the body of the drive, although it is not likely to be damaged that easily if unprotected. Here is a class 10, 128GB SD card for you from Sandix:Ī flash drive consists of a small circuit board carrying the necessary circuit elements and importantly a USB connector, insulated electrically, and protected inside a plastic or metal or rubberized case, which can be carried in a pocket. The UHS-1 has also a minimum sequential writing speed of 10 MB/s but it’s slightly better than class 10. Mostly we use microSD card.Ĭlass: Based on read and write speed rating there are different Classes of SD cards.Ĭlass 2 has a minimum sequential writing speed of 2 MB/s and functions smoothly for normal recordings like SD video recording.Ĭlass 4 and Class 6 have a minimum sequential writing speed of 4 MB/s and 6 MB/s respectively and functions smoothly for normal HD recordings.Ĭlass 10 has a minimum sequential writing speed of 10 MB/s and functions smoothly for Full-HD recordings and large HD files. The SD’s are available in the original size, the mini size, and the micro size. Though the 2 TB storage SD hasn’t been made yet. The SDHC card can store data up to 32 GB.Īnd the SDXC card can store data from 32 GB to 2 TB.
Step 5: check files to recover when scan is completed.The SDSC card can store data up to 4 GB storage. Step 3: select the inserted SD card to scan.
Only when the SD card is properly inserted into card reader and the card reader USB interface is properly connected to computer, can we succeed in accessing SD card and reading/writing data correspondingly. Using skills: insert SD card into the corresponding slot on one end of card reader, and then connect the USB interface on the other end of card reader to computer. What's more, the function of card reader with SD card inserted is basically the same with that of USB flash drive.įor a computer, the card reader is similar to a USB floppy drive the tiny difference lies in - what the card reader reads is a variety of flash memory cards while USB floppy drive only reads floppy disk. Some of the card readers are even close to that of common USB flash drives. Usually, an SD card reader is not very heavy and the size of it is small. Besides, it supports reading & writing data and allows the access to SD card files.Īctually, a card reader is specially designed to share information on SD card conveniently. It's an external device with corresponding SD card slot and USB interface. Well, SD card reader is a kind of device used specially for reading SD card. It is now widely used in digital camera, DV, MP4, MP3, PDA and smart phone. And it is favored and used by a lot of people due to its excellent characteristics of small size, fast data transfer and hot swap.Īt present, SD card is the most common memory card on the market. On This Page :Īs a new type of storage device based on semiconductor flash memory, SD (Secure Digital) memory card is produced to increase the capacity of digital devices. Now, you can read this post to learn some useful information about SD card reader.
Thus, to access to the files on the SD card using the computer, you need an SD card reader. You know that you can’t connect the SD card to your computer directly.
