The most important features of an SD card Must Check Before Order online:-
The most important features of an SD card are speed, reliability, price, and warranty. SD cards are most commonly used in cameras for storing image and video files as you shoot them. Because most cameras can take photos faster than they can write them to storage, images are first saved to a small but speedy buffer in the camera. Once the buffer is full, the images have to be written to the SD card before you can shoot any more photos. The faster the host device can write data to the card—the card’s write speed—the faster this buffer clears and the sooner you can start shooting again. So write speed is the most important spec for SD cards.
Read speed is important when copying data from the card to a computer via SD card slot or USB 3.0 reader, and when reviewing photos on the camera. Read speed is not as important for cameras as write speed, but because read speed is often faster, manufacturers like to brag about it on the label. Read speed is more useful for SD cards used for additional storage, since you’ll mostly be accessing media that you’ve already put on the card. Almost every SD card we tested in early 2016 had an average read speed of around 92 MB/s, with little variation between cards.
An SD card holds the only copy of a photo between the time you take it and when you copy it to a computer for editing, so it’s important to get a reliable card from a reputable manufacturer to minimize the chances of something going wrong. Many SD cards come with a lifetime or 10-year warranty, and the SD Card Association says most SD cards have a life span of about 10 years with “normal usage.”
Keeping these criteria in mind, we researched SD cards from SanDisk, Lexar, Samsung, Toshiba, Transcend, PNY, and others. Unfortunately, the sources we’ve relied on in the past to help us choose which models we test—like professional sports photographer Chuck Steenburgh and Tom’s Hardware—no longer review lots of SD cards. So we tested more cards this time: 10 in all.
We tested the 64GB versions of the SanDisk Extreme, SanDisk Extreme Plus, SanDisk Extreme Pro, Samsung Pro Plus, Lexar 633x, Lexar 1000x, Transcend W60MB/s, Transcend W85MB/s, PNY Elite Performance, and Toshiba Exceria UHS-I.
We tested each SD card’s real-life burst-shooting performance on two entry-level DSLRs (the Canon Rebel EOS T4i and the Nikon D3300), a mirrorless camera (the Olympus OM‑D E-M10), and a compact camera (the Sony RX100 MKIII). We tested with a variety of cameras because an SD card’s performance can vary from camera to camera based on memory controllers, image processors, and a slew of other factors—the fastest card in any one camera won’t necessarily be the fastest in every camera. For each card, we averaged these test results to get an overall measure of performance.
Using a USB 3.0 card reader in a 2015 gaming laptop’s USB 3.0 port, we ran CrystalDiskMark, a benchmarking program designed to test sequential and random read and write speeds on solid-state storage. (We tested SD cards via USB 3.0 to prevent bottlenecks, since USB 2.0 tops out around 33 MB/s and the cards we tested are faster than that.) Between each test, we cleared the cards and reformatted them using the recommended utility from the SD Association to stabilize performance.
