Sandisk Extreme III SDHC 4gb - £12.49 @ Amazon

Before folks start cold voting because its expensive for an SDHC, please note that the read/write speeds are blazingly fast for these and as such suited for DSLRs and the like. Please see the following link:

Link: http://www.valueflash.co.uk/sd_chart.htm

I needed one for my Pentax K-M as it only accepts SD/SDHC and this is the best price/GB for the extreme cards.

As an interesting point, the "Class No." classification system is not as obvious as it looks. The classes range from 2, 4 and 6. At class 6, it means that the card can perform writes at 6mbs, class 4 at 4mbs etc. Cards such as the Ultra series (15mbs) and Extreme (30mbs) can write a lot faster but it isn't defined within the classification. As such, cheaper cards can rightly claim Class 6, reading at 6mbs but not necessarily 30ms like this one :)

Hope this helps someone.

Same price at play.com for anyone with any spare playfunds and



Not the same item at Play - 20mb/second sequential Read/Write speeds :x

Amazon is the newer revised Fast 30MB/second sequential Read/Write speeds..

HOT!!!

but play.com has a generic 8gb class 6 sdhc for £9.99.
I wouldn't pay an extra £2.50 for half the capacity at a slightly better speed.
Most DSLR's buffer the memory cards, so you are only slowed down after taking a few shots in RAW mode.
I don't think there is a big advantage for the extra speed in this usage scenario.

Maybe if i was using it as extra disk space in an Aspire One, but then 4gb is too small...

Definitely a 'case of horses for courses'
Hot from me.

I got the ones from play - its not obvious but they are class 6 so fairly quick! works well with my D80

I got this a few weeks back, very good deal I thought, also I don't think its a good idea to have anything much more than a 4GB card, if you use just 1 card and have any sort of error, you lose the lot, if you have extra small capacity cards with you, all is not lost :)
#7
despite the availability cheaper, larger capacity cards - this is a good price for a superior card - I have 2 for my Canon 450D, and they are very fast - large JPGS just rattle away in continous shoot mode 25+ shots without slowing down - in RAW about 6 frames before it slows a bit. def hot, and I'm getting another one as they are so good.

how does this make a difference in a DSLR camera performance...sorry I am new to DSLR

I think you have just proven my point...

What you are describing is the built in buffer, not the speed of the memory card!
When you take the first 32Mb of photos they are being stored into the internal memory buffer before being offloaded to the memory card
By using a high speed card you determine how fast you can take photos AFTER the first 25 JPEGS or 6 RAW photos. (not important in day to day usage)

So for day to day photography there is no noticeable difference with the speed of the card, until you dump the photos to the computer, when a fast one may take 2 minutes instead of 3.

There are situations when faster is better, but I'm not convinced that using a DSLR is one of them. Have you tried a class 2 SDHC in your Canon? I reckon you will notice no difference until you dump the photos to your computer...

the Amazon product code is SDSDRX3-4096-E21

SanDisks product code for the 30MB/s 4GB edition is SDSDX3-004G-E31, this is the class 6 not the 30MB/s

Its the E21 and E31 bit, E31 is the 30MB/s card

The 30MB/s card product code is: SDSDX3-004G-E31

Neither Amazon or Play cards linked are the 30MB/s version

Incorrect, the point that oldrichie makes is determined by the speed of both buffer and memory. The faster the memory card, the slower the buffer is used up, and hence the more pictures that can be taken consecutively at maximum speed.

mumbojumbo
I don't think it's guaranteed that you will get the newer 30MB/s card. Some of the reviews this month mention receiving the older 133x speed cards. If this is the case then you would definitely be better off getting a Integral High Speed SDHC card at around £10 for an 8GB version.


I ordered 4 of these a few weeks ago from Amazon and they were all 30mb/sec HTH :)

Yes and the effect of this is going to vary depending on how much buffer your camera has, how many pictures you take at once and the resolution of the pictures you are taking.

The only people who would notice, would be people taking lots of continuous photos in RAW mode, eg paparazzi or sports photographers. If you shoot in JPEG, you will never run out of buffer.

My argument is that for most people with a DSLR, they will never notice whether they have a 30mb/s sandisk extreme III or a 'rubbish' generic x2 card whilst taking photos.

When they dump to a computer, the quicker card will be obvious, but waiting 2 minutes vs waiting 3mins for the photos to dump would not pursuade me to choose a 4gb Sandisk Extreme III for £12.50 over an 8gb generic play class 6 card for £10.

My advice to anyone, would be to choose the 8gb card for £10. which is not the 'best in breed', but still excellent and best value for money! (which is what hotukdeals is all about)

If you are a professional then you will not get extreme III, you will get the fastest available on the market, such as the ducati edition.

For me it's all about upload speed, hate sitting there for ages wairting for all my pictures to be uploaded onto my PC using it's card reader..

With this card its zoom Zoom ZOOM!!

HOT!
#17
Just to point out that the buffer doesn't always work so well - my Dad swapped his fancy Kodak digital for my older model because it was too slow - Dropped my Sandisk Ultra III 2GB in there, and there was no lag at all.

He took it back when he realised my camera was "just as slow", though P

IT IS THE SAME! :whistling:

The one play sent me last week was the newer revised Fast 30MB/second sequential Read/Write version, I used some playfunds and the 5% Discount code to buy it hence the reason I posted the info :roll:

I think its pot luck what one you will get from play or amazon going by recent reviews, and both sites also previously had the same wrong info about a free card reader and software (which nobody got).
