Full DOs and DONT's

Don't know which card you need?

SD card

 

If you're unsure of which type of flash memory your gadget takes, try Ritzpix's guide. It's not comprehensive, but it's fairly detailed. Alternatively, just Google the name of the product; you should be able to find it on a product description somewhere.

What "class" memory card do I need?

Memory cards are categorised by the speed that they can take and upload pictures or video. This is called "class", eg class 2, class 4. But unless you're David Bailey, you probably don't need to worry about the class of your memory card - top speeds are only really a necessity for sports/action shots, or professional standard video recording.

The SD Association, which was established to develop and promote memory card storage standards, has a handy guide to the range of speed classes available and their associated benefits.

SD and SDHC - cheapest and most common

The postage-stamp size SD (Secure Digital) and SDHC (Secure Digital High Capacity) memory cards are common in many cameras and other gadgets which need expandable storage.

Our top picks, which include some of the cheapest on the market alongside some of the pricier, best reviewed ones, can be found below.

  • Kingston 4GB SDHC class 4 card - £2.20 delivered at Rakuten* (third party seller)
  • Integral 4GB SDHC class 10 card - £5.10 delivered at Amazon* (third party seller)

High performance SD cards

The cards above are fine for regular snaps and storing media etc, but they're not exceptionally fast. If you want to shoot fast-action photo sequences or record seamless full high definition video (and be able to quickly transfer the contents of your memory card to your computer) you'll need one with faster read/write times to keep up.

The "Ultra" SanDisk cards below have good feedback for doing exactly that, though they cost a bit more.

  • SanDisk Ultra 8GB SDHC class 10 card - £4.89 delivered at 7dayshop*
  • SanDisk Ultra 16GB SDHC class 10 card - £7.73 delivered at Amazon* (third party seller)
  • SanDisk Ultra 32GB SDHC class 10 card - £12.98 delivered at Amazon* (third party seller)

Micro SD, SDHC and SDXC - common for mobile phones

Micro SD next to SD card

Micro SD cards are about a quarter of the size of a standard SD card, and are most commonly used in mobile phones.

But they can still be used with devices that have standard SD card slots, by inserting the card into a special adapter. Many Micro SD cards now come bundled with an adaptor.

Micro SD cards

  • Team 2GB Micro SD with SD adaptor - £2.43 delivered at Rakuten* (third party seller)

  • Team 32GB Micro SDHC class 10 with SD adaptor - £8.99 delivered at Amazon* (third party seller)

More memory

Newer SDXD (Secure Digital eXtended Capacity) cards have a greater capacity than SD and SDHC ones, ranging from 64GB to 2TB. These must only be used with SDXC devices. This guide outlines which SD memory cards are compatible with which host products.

  • SanDisk Ultra 64GB Micro SDXC class 10 without adaptor - £17.99 delivered at Rakuten* (third party seller)
  • Kingston 64GB Micro SDXC class 10 with SD adapter - £20.09 delivered at Rakuten* (third party seller)

Additional memory storage devices

We've outlined the most popular forms above, but there are many other options for memory storage, whatever the device you're using.

USB stick - for your laptop or computer

USB stick

There's one big advantage with flash drive USB sticks: you'll get lots of memory for less money.

The idea with flash drives is that you load your photos or videos onto your computer from your camera, and then save them on a USB stick for safe keeping.

  • Lexar 8GB USB 2.0 flash drive - £2.99 delivered at eBuyer*
  • I-Onik 16GB USB 2.0 flash drive - £4.24 delivered at Rakuten* (third party seller)
  • I-Onik 32GB USB 2.0 flash drive - £7.44 delivered at Rakuten* (third party seller)
  • Team 64GB USB 2.0 flash drive - £14.76 delivered at Rakuten* (third party seller)
  • iBoutique 128GB USB 2.0 flash drive - £25.98 delivered at Amazon* (third party seller)
  • I-Onik 256GB USB 3.0 flash drive - £70.60 delivered at Rakuten* (third party seller)

Portable external hard drives - for your laptop or computer

Compact Flash card

External hard drives are a great way to store large amounts of data like photos, movies and music. They're much bigger than USB sticks, but they connect to your computer in the same way, via USB 2.0 or the faster USB 3.0 standard.

  • HGST 500GB USB 3.0 external hard drive - £32.98 delivered at eBuyer*
  • Toshiba 1TB USB 3.0 external hard drive - £43.58 delivered at eBuyer*
  • Samsung 2TB USB 3.0 external hard drive - £58.99 delivered at Rakuten* (third party seller)
  • Toshiba 3TB USB 3.0 external hard drive - £74.98 delivered at Amazon*

Sony Memory Sticks - for Sony devices only

Memory Stick

If you've got a Sony camera, camcorder, MP3 player, PDA, mobile phone or a PSP, you often need a different format of memory card called a Memory Stick. These come in numerous versions, much like SD cards, with adaptors to fit them in different-sized slots.

However, new Sony products now support SD/SDHC cards, which are usually cheaper, though you should always check they're compatible with your gadget first.

Got a Sony Memory Stick Pro Duo-based device but only have a Micro SD card? You can buy card adapters which are quite cheap and will bridge the gap between formats, making micro SD cards sit happily in Memory Stick devices

  • Sony 4GB Memory Stick Pro Duo Mark 2 - £7.95 delivered at Amazon* (third party seller)
  • Sony 8GB Memory Stick Micro Mark 2 - £15.99 delivered at Amazon* (third party seller)
  • Sony 16GB Memory Stick Pro-HG Duo HX - £24 delivered at Amazon*
  • Sony 32GB Memory Stick Pro-HG Duo HX - £42.45 delivered at Amazon* (third party seller)

CompactFlash - cards for SLR cameras

Compact Flash card

The oldest type of flash memory covered here, CompactFlash, is still sometimes used as the format of choice for higher-end digital SLR cameras due to its longevity and durability.

Canon has also chosen CompactFlash as the recording medium for its professional high definition tapeless video cameras.

  • Kingston 4GB CompactFlash card - £7 delivered at Amazon*
  • Kingston 8GB CompactFlash card - £8.25 delivered at Amazon* (third party seller)
  • Kingston 16GB CompactFlash card - £13.52 delivered at Amazon*

As with the SD cards above, more demanding applications will require CompactFlash cards that can be read and written faster. The SanDisk Extreme range has some of the best feedback available, and is basically industry standard for pro photographers.

  • SanDisk 8GB Extreme CompactFlash card - £21.99 delivered at Rakuten* (third party seller)
  • SanDisk 16GB Extreme CompactFlash card - £33.70 delivered at Amazon*
  • SanDisk 32GB Extreme CompactFlash card - £45.99 delivered at Amazon*
  • SanDisk 64GB Extreme CompactFlash card - £60.99 delivered at Amazon*
