Selecting the Best Memory Card

Buying a memory card

Buying a memory card is the last thing you need to do before you can start taking photographs. Having already spent time deciding on a cameras the memory card is usually a choice that photogrpahers want to get over and done with quickly, which is quite understandable as it is only the recording medium.

Mercifully there are not many considerations. But consider them you must and these considerations are.

What type of card (This is easy).

How much storage (Down to the length of your photo shoots).

What write speed (decided by the performance of your camera)

Types of memory cards

Compact Flash, Secure Digital and Memory Stick

The above types of card form the basis of literally all card fits. In particular Compact Flash and Secure Digital with Memory sticks being a their own fitting from Sony which they have used in a variety of their electronics goods.

There used to be a bit of a standards war but this has very much settled down now.

There are other types of card such as 'micro SD' but these are a type of Secure Digital card and can be used with a plastic carrier.

Your camera will most likely take one of these fits. If it doesn't, your choice will be limited but you should still heed the following points.

Storage space

How many exposures

Like all digital recording mediums, memory cards have a certain level of storage space. More storage means more cost but its usually not proportional. However before you buy the largest card you can find or afford, consider that if the card corrupts you lose that many more photos. For those going on holiday, do they REALLY want to risk losing all their holiday shots because they were on the same card?

How big are the images, 10Meg, 25Mg?....How often will you take the photos off the card and into your PC/mac.... If its often say after an evenings shoot then a massive card may well be pointless. Will you be shooting dozens of frames per minute? I shoot live music. Maybe 2 shots per minute. I find I am unlikely to fill more than one 4 gig card per average shoot. I have 4 x 4Gb cards for festivals etc... If I have a PC with me then the PC can retrieve photos while I continue to shoot.

The size of the cameras memory card decision is very much down to your workflow.

Memory Cards read and write speeds

How fast can your camera save images to a memory card.

To achieve optimum performance from your digital camera you need to match the card's read/write speed to the upper limit of the camera.

The cheapest card in your chosen size and fit may not be the best choice for you and likewise buying a blisteringly fast card may be a waste of your resources.

Sandisk used to call their cards Ultra, UltraII, Extreme III, Extreme IV etc which denoted speed.

• Normal Sandisk (blue card) 3MB/s- Low end compact cameras
• Ultra II 15mb/s (soon to be 'Ultra') - High end compact cameras
• Extreme III 30mb/s(soon to be 'Extreme') - D-SLRs
• ExtremeIV 45mb/s(soon to be 'Extreme Pro') - Pro D-SLRS

If your PC or mac does not have a memory card slot (many do btw) then you will require a USB card reader.

Sandisk USB 2.0 readers work at 30MB/s and 35MB/S. If you had extreme IV cards then you would need a Sandisk Firewire 800 reader, however Apple Mac compatibility has in the past been problematic. USB 3.0 is just around the corner and it is likely that Sandisk will release a faster USB reader.

Speed classes also describe how cards handle video -

How to detect fake Sandisk micro SD 32GB

SanDisk microSDHC 32GB Card

How to detect fake Sandisk micro SD 32GB 6 Feb 2011

By Dr. Sanjeev Sharma

Any attempt to look for some advice to buy a genuine Sandisk microSD (any strength - in my case a 32GB card for my Samsung GALAXY tab) is met by a plethora of internet-based opinions and information as regards the masses of fake cards flooding the markets these days....most originating from some wheelie bin outside a Chinese factory.

Human that I am, I looked around for a week and realised that dependable sellers (Amazon, Play.com, PC world etc) were all selling a Sandisk 32GB card for £ 70-85 while the shady ones (Amazon marketplace, eBay etc) were dishing them out at £25-40! Hence, I decided to try my luck (and money) and bought one card from eBay after an extensive search. It cost me £35.00 + £1.98 and the seller was a `power seller' with 100% feedback. Nothing could go wrong......or I assumed huh...?

As explained below, it was a fake and after a bit of wrangling (and legal threats!), I got my money refunded. Wisdom dawned upon me and I then bought a genuine one from Amazon UK for £69.99 which was delivered free inside 24 hours! Being at the receiving end of a con, and in the absence of any constructive advice available, I have made the following tips to help the next customer - hope this helps:

DIFFERENCE BETWEEN GENUINE AND FAKE Sandisk 32 GB micro SD: (see my self-explanatory photographs for each point)

1. Package: The genuine pack is sealed and cannot be split open. The fake is just pasted at the edges and my fake item was all loose inside. Again, as far as I am aware, Sandisk does not provide any SD adaptors (Kingston does) but nearly all eBay items have a `free adaptor' inside the same pack.

2. Check the barcode: If you have a iPhone with a barcode facility (like a Amazon/eBay app), check the barcode on the reverse of the pack. My fake eBay item barcode read 4GB instead of 32 GB.

3. Check the external details: Sandisk, currently only makes Class 2 for its 32 GB micro SD cards and I confirmed this from Sandisk helpline in the US. eBay sellers are selling fakes as `Class 6 - 10' !!!

4. Check the inner details: Once you open the pack, check the card. All genuine cards should have a serial number and a manufacturing country's identity. Fake ones neither have any such details and the external details are painted in a hazy style (see photo).

5. The Catch: When you put in a fake micro SD card for the first time, you will be surprised to find that it reads the correct GB in the properties. Apparently the goons have made a software which enables the card's storage properties to give out a false capacity. One way to check this is to copy at least 60% date of the `claimed' capacity and check the card in 2-3 days time. There will be lost data in all fake ones.

6. Finally the functionality: Download a simple programme called H2testw (ver 1.4) from the internet. It is German software and the most recommended to test all your portable media including micro SD cards. My fake one showed only 3.96 GB capacity instead of 32GB as claimed.

7. Where to buy: spend the extra bit of money and buy from genuine big dealers. Amazon is always one of my foremost places but keep away from Amazon Marketplace since the same firms also sell in eBay i.e they are mostly shady and refunds will need a lot of wrangling. Of course, you might occasionally be lucky (as yours truly had hoped!), but one would probably need to be as dumb as me to follow my steps (till I became wiser!.

Hope these steps help the next prospective buyer. Feel free to correct me if you do not agree!
