Before I begin this review I would like to point out that this type of memory card is more suitable to a digital point and shoot camera rather than a digital DSLR, the reason for this is that most DSLRs have burst modes and for this reason you will want to get a class 6 card. However if you’re looking for a SDHC card to go in your point and shoot digital camera keep on reading. Now most of you may think a SDHC card is a SDHC card, you may throw any one in there and snap your pictures, but think of this: what if you had been taking photographs of an event such as a 1st birthday, a christening, a wedding or even a music concert when all of a sudden your card fails and all of your photos are wholly destroyed. You then have 2 choices you may either cry or you may compensate an extortionate amount to have a great deal of expert recover your pictures, nevertheless the problem is that not all of these pictures if any are guaranteed to be recovered. Suddenly a storage card isn’t just a card any more is it? What I liked in regards to this memory card is that there are no moving parts inside it, now you may be thinking so what but this leads to the reliability of the device and more significantly the higher chance of your images being protected. No moving constituents mean that not one thing is going to get worn down or damaged. Another magnificent feature of this class four memory card is that there will be a uninterrupted 4MB read speed which is splendid for when it comes to uploading your images to a computer. Overall the Kingston 4 GB Class 4 SDHC Flash Memory Card is lowcost and very dependable and you can’t ask for any more when it comes to memory cards.

For those of you who are unsure of what card to buy/feel like brushing up on your memory standards: SDHC was created as a successor to the SD (Secure Digital) and MMC (MultiMediaCard) formats. When the original SD format was created a while ago, its maximum capacity was 2GB. Since flash memory is so cheap now, you’ll rarely find any SD card other than the maximum 2GB flavor around anywhere. Enter SDHC (Secure Digital High Capacity). SDHC adds two main things to the former SD format: 8GB is pretty much equivalent to the space of a double-sided DVD. Yeah, an entire double-sided DVD in the size of a stamp. 2000 moderate quality mp3′s, 11 CD’s, over 1100 12MP photos, and depending on your camera’s format anywhere from 30 minutes (MJPEG probably) to 90 minutes (DIVX/MP4) of 720p HD video, over 3 hours of VGA video @ 30fps–it’s pretty sweet. Class is important here if you do any of the following: This card is rated as Class 6. This means the MINIMUM transfer speeds, ie: reading and writing, happen at a minimum of 6MB/s (that’s megaBYTEs not megaBITs per second). I tested this card with a few large file transfers from my laptop, and found the following (EDIT: scroll down a little for updated read/write speeds): This is fast enough for taking all VGA (640×480) video, about two higher quality 10MP photos every second, and most 720p HD (1280×720) video. It should be ample as extra storage in a netbook, though it’s about a third the speed of a notebook hard drive. Class 6 is a sweet spot right now in terms of price/performance. Class 10 is much faster but of course much more expensive, and class 4 isn’t that much cheaper IMHO. A note on capacity: Capacity is measured really stupidly in all digital media storage (hard drives, memory cards, etc). All companies define a gigabyte to be 1000MB, and a megabyte to be 1000kb, etc etc. In reality it’s 1024KB per MB, and 1024MB per GB. Not a huge difference, going from 1024 to 1000, right? Well, sort of. This card has a capacity of 8,027,897,896 bytes after formatting (manufacturers will say ‘See! Over 8 billion bytes!),’ which equates to 7.47GB. When you’re wondering where the other 0.5GB went, it’s because manufacturer conversions ate it. I hope they’re happy. Ah well. Patriot is cool. Anyways, this card is great. Patriot is pretty awesome with memory, and I see their customer service reaching out to people who have had memory mishaps all the time on here and on Newegg. Hope this helps some people. Sorry if I confused anyone! Happy, erm, memory-writing? That is all. ::EDIT June 9, 2010:: A note on read and write speeds that I posted earlier: you will probably see better speeds from your computer than your camera. Here’s an updated comparison of its average performance after using the card for a few months: In my computer: Here you see the limitations of a camera’s SDHC card controller. What this means is my camera can only talk to the card at a certain speed, but my computer (being more powerful than my camera) can talk to the card much faster. Despite this it’s still plenty fast enough for 720p video in my camera. I have a simple point and shoot, so your camera might be different. What’s the point of this? Honestly, not much. But I’m sure someone will find it interesting! So 6 months and thousands of photos and videos later, it’s still a fast and reliable card. ::Quick further edit June 12, 2010:: *That* is all. 14 of 14 people found the following review helpful. 45 of 53 people found the following review helpful. So, based on this, I purchased a third for my spouse’s DSLR in February. To my surprise, it appears identical, even with the same part number, but Patriot changed the design. The biggest problem is that it is too big. It jams in several of the card readers I have including that in a primary laptop. It jams in my digital camcorder. These devices use a push to eject mechanism, and they don’t eject. It really takes a lot of effort with really good fingernails to pry it out since the spring eject is not strong enough. Further, they redesigned the insides. It is now about 2/3 of the speed previously–which is still very good, but obviously they changed the design and went to a cheaper MLC flash. Either that or Patriot sources these from multiple facilities, and I was just lucky. Before, I would wholeheartedly recommend this, but not any more. |
