Best SD Cards

SanDisk, Lexar, and PNY are brands that make the best Memory cards. The best memory cards I have used have been the SanDisk Extreme Pro SD cards.

That does not mean you need to buy a card made by SanDisk for your Sony ILCE-A5100. Look for SD cards with impressive names. That will make sure you get fast transfer rates, shock resistance, and other professional features.

I have not run into problems with Lexar Professional or PNY Elite Performance cards.

The problems I have had with memory cards has been when I have used inexpensive no name brands. Not having a brand name increases the chance of card errors or corrupted data.

If you would like to spend less, don’t buy a cheap card. You will avoid problems by buying a high-quality memory card with a smaller capacity.

Sony A5100 SD Card Compatibility

SD, SDHC, and SDXC memory cards are compatible with the Sony A5100. Use a card to get the best overall performance from the A5100.

The brand new SDUC memory cards will not be useable in the A5100.

There are four different types of SD (Secure Digital) memory cards. Newer card specifications add more features that provides for greater storage space and noticeably increased transfer speeds.

  • Secure Digital eXtended Capacity (SDXC) - 64GB to 2TB.

SD Card Speed

The speed rating of an SD memory card is based on the sequential read and write speeds. The write speed of a memory card is essential for video in addition to continuous shooting.

A slow memory card can reduce the number of continuous images the Sony A5100 can take. This is due to the camera’s buffer not being able to write data to the card fast enough.

When recording video, a slow card can cause an unexpected end to shooting. The video file might also be corrupted. If you intend to record video, it is essential the memory card you use meets the minimum requirements of the camera.

Read speed is important for transferring files to a computer. If you have cards that are full, a SD card with a fast read speed will cut down on the amount of time it takes the transfer to complete.

Speed Class Rating

SD Card Speed Class

A SD card is labeled with a Class rating based on the continuous data write speed of the memory card. Class 10 is the maximum rating, even though cards are made that have a faster read speed.

Here is a list of the Class ratings and their associated minimum read/write speeds:

  • Class 2 - 2MB/s
  • Class 4 - 4MB/s
  • Class 6 - 6MB/s
  • Class 8 - 8MB/s
  • Class 10 - 10MB/s or faster

Virtually any SD card worth choosing for the Sony A5100 will be a Class 10 SD memory card. In the time since the announcement of the camera, SD memory cards have gotten much faster.

Sony A5100 PRO Duo Card Compatibility

One PRO Duo or PRO-HG Duo cards can be used in the Sony A5100. PRO-HG signifies the memory card may have read speeds up to 50MB/s and a 15MB/s minimum write speed.

PRO Duo memory cards are consistently double the cost of an SD card. I would not recommend purchasing a Sony PRO Duo card for your A5100 on account of the increase in cost.
