Great value memory,
Verified Purchase(What is this?)
This review is from: Kingston 8GB Micro SD HC - Class 4 (Electronics)
Before getting to the actual memory card, I'd first like to mention two things I like:
1. It comes with the MicroSD adapter - something I find very useful.
MicroSD is almost *the* standard for mobile phones (with even stubborn manufacturers like Sony Ericsson slowly ditching their proprietary formats in favor of this) but the problem is, a lot of larger products (like cameras and laptops for instance) take only the standard SD card.
Here, it is advantageous to have the adapter because all you have to do is plug the card in your adapter and you're ready to transfer your pix/files from your phone to your laptop and vice versa.
2. The packaging won't injure you.
Quite frankly, I'm sick and tired of those horrible plastic-clamshell packaging which takes a knife and two steady hands to cut open; fortunately, this card ships in a neat cardboard cover which surrounds a re-sealable plastic 'case' that can also double as a storage case in case you need it (although wasn't probably intended for that purpose).
Getting to the actual card, I found the card reasonably fast with okay read and write speeds; this is most likely attributed to the "Class 4" speeds it carries, but to be honest I'm not too sure what that means for the average joe (who's probably only going to use this on their phone or whatever)
The only (small) complaint I have is that its a tad bit difficult to pull the memory card out of the adapter, but then that's hardly a complaint considering the performance and the price, so I gladly give this five stars.

Kingston - Flash memory card ( microSDHC to SD adapter included ) - 4 GB - Class 4 - microSDHC Yes, it WAS a good price at £2.65 in April. Amazon have noticed how popular this made it. Today (31.8.11) the price has just leapt 54% - to £4.09. I hesitated to buy it myself as there was a £3.99 delivery charge to Europe. Fortunately, I was able to obtain one FOR NOTHING by ordering some printer ink catridges somewhere else. But a splendid item nonetheless. Having the adapter included is especially useful. Mine even arrived with a little plastic container to make it a little less easy to lose. Perfect product. Only wish Amazon et al were not so greedy.

Hi i am the same,fed up with all the plastic package.Ya need to get ya tool box out just to open the dam thing.
Class 4.Is to do with transfer speeds etc.

"Class 4" on a micro card means the transfer rate to and from devices is 4 megabytes per second.
Consequently "Class 10" is 10 megabytes per second. 1Megabyte is the equivalent of a millionbytes or 1Mb. 1 Kilobyte or Kb comprises 3024 characters. Muliga.

Good information, Muliga. As with all of computing, though, you have to check very carefully what you write. 1 Kb is, of course, 1024 characters, not 3024.

Not true - Class 4 means a minimum sustainable READ speed of 4MB/s and Class 10 means a minimum sustainable read speed of 10MB/s; burst speeds could be higher (i.e. for modest size files). Write speeds will normally be slower than these figures, sometimes significantly slower, depending on the quality of the card and its embedded 'firmware'; you are also likely to see much slower write speeds if copying large numbers of very small files, than you would get copying a large file of the same overall size.
Read and write speeds are also hugely affected by the interface used, so for example a budget card reader can give write speeds less than a third of that available from a top quality device on the same card; normally there would be less difference in read speeds, but it can be quite noticeable.
Storage manufacturers use 1KB = 1,000B, 1MB = 1,000,000B & 1GB = 1,000,000,000,000B, but many operating systems report 1KB = 1024B, 1MB = (1024**2)B, 1GB = (1024**3)B, so a 1GB card (as sold) will often be reported by the operating system as 931MB. This is nothing to do with 'formatting overheads' as often reported - it is just different measurement standards, which don't really help the non-techie customer.
