How to choose the right memory card for your Sony A7S II

Section 1: UHS (Ultra High Speed) Card Classification

You will find few memory cards with Ultra High Speed (UHS) classifications that determine maximum reading speed of your card. Presently, you can find two major types of UHS classifications as UHS-I and USH-II where the first one is rated to serve at 104MB/s and second one serves at 312 MB/s. It simply means that footage in USH-II cards can be offloaded 3x faster but to maintain this speed you need to have a fast connection and fast hard drive.

The SDXC card technology was launched in 2010 to serve the requirements of full HD recordings with higher speed and capacity. However, these cards follow dimensions comparable to SD as well as SDHC cards but they can support only SDXC devices. You can find these cards ranging from 64GB memory capacity to 2TB and the speed variation goes from 104MB/s to 300MB/s respectively.

• These cards provide higher storage capacities ranging between 64GB to 2TB.
• Its exFAT type file support allows users to work with large files with higher bitrates.

2. Speed Class Rating: U3

Some of the common specifications that manufacturers provide with their cards are write speed limits and burst read details but both of these cannot help user to get right card for their 4K video needs. Actually the ratio between burst rate and speed does not follow a simple relation thus the best idea is to buy cards by checking their speed class rating. This speed class rating shows that your card will not reduce its writing speed below the specified speed class limit. Some of the most popular peed class ratings available in market are Class 10, U3, U1, Class 6 and Class 4.

• The U3 or UHS speed class 3 cards are designed to serve compatible speed rates for A7S II cameras.
• They can maintain minimum write speed value of 30MB/s.

3. Card Capacity

As advanced 4k recording cameras like A7S II are designed to work with high capacity cards so the best idea is to buy a card with 64GB capacity so that all frames can be processed without any loss in information. In order to get best results for your classic 4k recordings always prefer to pick a card with higher rating. When you buy a card with higher capacity:

Features

• You will be able to minimize the risks of sudden card failures. Because when cards are not able to support higher bitrates then they often lose most of the information. It is good to choose a card that can easily record footage up to 1 or 2 hours.
• Note that there is no money saving deal in memory card price ranges. When you go to buy a 128GB memory card it will naturally cost same as if you buy two 64GB cards.
• The SD cards are small sized, compact units so whether you carry a 64GB card in your pocket or choose a 128GB package, none of these are going to put additional weight on your pocket.
