Digital technologies have advanced our lives more rapidly than any innovation. Our lives becoming more comforted and easier in this modern era.
Now-a-days people are more into using digital technologies as they are much more convenient to use, like smartphones, we can use them for anything for example, capturing photos and videos, digital payments, accessing social media etc. We are more informed and updated by what is going around the world and all of this with the help of smartphones. But it might have limited storage based on the device features depending on its price. A small size removable card known as SD card (secure digital memory card) is used for storing data which is capable of holding 2GB to 2TB of data depending on your device and also available in standard, micro, and mini sizes. A SD card weights approx two grams and are tiny in size almost as the size of postage stamp. There are more commonly three types of SD cards-full size, miniSD and microSD. SD cards are used in Mobile phones and smartphones, Digital cameras, Video camcorders, Gaming consoles, Newer TV models, MP3 audio players and many more.
SD cards standard are all across multiple market segments of the portable storage industry, including mobile phones, digital cameras, Personal Computers, MP3 players, car navigation systems, printers, electronic books, tablets, electronic devices set-top boxes, and home theater devices like Blu-ray players, as well as smart home/Internet and many more devices.
The first 128 GB microSDXC card is introduces by SanDisk in February 2014, a 128 GB SDXC card in September 2014 and a 200 GB microSDXC card in March 2015.
Although Samsung is the only company which came out with the world’s first 256 GB microSDXC card in May 2016.
Now lets talk about cameras DSLRs, if your digital camera is new, then they also stores images on SD cards. Last ten years manufactured cameras can handle SDHC cards.
And if we talk about the older cameras or DSLRs some of them use CF (Compact Flash), Memory Stick variants or combinations.
Some more olders one’s uses xD cards or even SSFDC. And more importantly many older cameras originally designed for SD or for SDHC have been modernized to accept the recently developed SD flavors through camera firmware updates. But you have to make sure firmware is up-to-date if you possess an older product
Recent launches supports high resolution and 4K8K video recordings. Not all SD cards offers same speeds. For instance, if you’re a professional photographer who needs rapid succession on a DSLR camera and saving them in a high-resolution RAW format, you’ll be needing the fastest SD card.
This’ll allow your camera to save images as quickly as possible same goes for recording high-resolution video and save it directly to the SD card.
Manufacturers of SD cards use a term “speed classes” to measure an SD card’s speed. Differentiated in 4 speed classes as.,
* 10 (10MB/sec read/write speed), Class 10 is the fastest, suitable for “full HD video recording” and “HD still consecutive recording.”
* 6 (6MB/sec),
* 4 (4MB/sec),
* and 2 (2MB/sec), Class 2 is the slowest, suitable for standard definition video recording.
There are also two Ultra High Speed (UHS) speed classes, 1 (10MB/sec read/write speed) and 3 (30MB/sec).
These markers are mainly intended for devices designed for professional use, but they are most popular these days.
And lastly, there are Video Speed classes which includes V90 (supports up to 8K video recording), V60 (4K recording), V30 (HD/Full HD video), and V10 and V6 (standard video).
Coming to durability of SD cards, they are quite durable except the electrical contacts and the lettuce that secures or surrounds them can be damaged if not handled carefully. So its important to be very careful while carring them, should only be carried in its original packaging box or the one which is available in markets.
SD cards comes with three different types of card storage : SD, SDHC (High Capacity) and SDXC (eXtended Capacity).
Intially , SD card could hold upto 2GB of data using microsoft’s FAT-12 or FAT-16 file format and this was actually huge amount till 1999, as the time passes in early 2000’s 2GB limits was becoming a problem after that industry launches hih capacity SDHC cards (Secure Digital High Capacity) with the storage capacity upto 32 GB.
Afterwards in late 2009, SDXC cards (Secure Digital eXtended Capacity) were introduced with the storage capacity upto 2TB. Later on SDUC cards (Secure Digital Ultra Capacity) appeared in 2018 with storage capacityupto 128 TB using exFAT.
SD cards store the data on electronic components called NAND chips which permit the encoding and storing of the data on the SD cards.
The NAND chips in SD card have a long life due to which the data can be written to them thousands of times over their lifetime.
There are so many reasons your card accidently gets spoiled or delete data from your SD card. Some of them are like.,
* Removing memory card while accessing the media on device, it may delete some of your data,
* Formatting SD card, display errors like ‘memory card not working’ or ‘format fault’ might be an indication of partly or wholly dead memory card,
* Sometimes SD card may also have a virus attacks,
* Many times deleting specific images takes up the whole of the data.
* Or what if, SD card gets stolen or accidently damaged by any reason so its always better and safest option to keep a backup of the content of your
SD card for long-term storage of digital photos.
But the good news is now there is a way to recover all the lost data with the help of stellar photo recovery software for your windows computer.
This tool not only recovers your data from the SD cards, but also comes in handy with laptop or PC drives, SSD, USB drives, and similar storage media.
In short The Stellar photo recovery is a handy and easy solution to recover your lost data. Enables recovery of file formats like, JPEG, PNG, GIF, RAW, and more.
