Crucial 2GB Secure Digital Flash Card
Recently Samsung sent me their SC-X210L Sport Camera that requires SD Flash memory, and I contacted Crucial to see if they had anything available to send out. They responded and in two days I received their 2GB SD Flash Card. The information that comes with this card doesn't claim to have blistering speeds so I wondered how fast (or slow) it actually performed. Many of today's cameras can write very quickly to memory, so I thought is was worth a look to see if the CT2GBSD from Crucial would slow down your camera. Let's take a look.
There is nothing really spectacular about the 2GB Flash card from Crucial in terms of appearance. It looks like a standard SD card. Like other cards available it has a write lock so that you can not over write the files on the card.

To test out this card we ran HDTach as a synthetic benchmark and then ran some test file transfers for some real world benchmarks. We compared the Crucial 2GB SD card with a Soultek 2GB 150x SD card as well as a Transcend 80x 1GB card. The Transcend 1GB card was just compared using the synthetic benchmark as our test file package was over 1GB in size.
Let 'er Buck!
In the first test we fired up the popular HDTach benchmark. This allows us to simulate both read and write tests on these cards. Keep in mind that the scores are synthetic and not real world.
The smallest card of the bunch - the 1GB Transcend card scored the lowest in the read test. It has a bust rate of 8.8MB/sec and averages 8.7MB/sec read, but has the fastest write time of the lot with an average of 8.9MB/sec. That's right this card can write slightly faster than it can read. . . at least in this test. According to HDTach it has a random access time of 1.4ms. It's not too shabby.
The second card we test up is the 2GB 150x Soultek card. It has the highest rated speed around, and scores not too bad. It has a burst rate of 9.9MB/sec and reads at an average of 9.8MB/sec. It writes slower than the 1GB card with only a 6.9MB/sec average. Its latency is slightly faster though at 1.2ms. Overall it performs quite admirably.
Crucial's 2GB card is up last and it also performs quite solid, although a little slower in some areas that the Soultek card. It has a speedy burst rate of 9.9MB/sec to keep up with the Soultek card and also reads at an average of 9.8MB/sec. It writes the slowest of the bunch though with an average write of 5.6MB/sec. Latency however is the fastest of the three at 0.9ms.
That's how they shaped up according to a synthetic test, but we'll take a look at the two 2GB cards in some real-world file transfers next.
For this last test we have taken a bunch of pictures and some small video clips and transferred them to the SD Cards. We then moved them back to a different hard drive in order to prevent caching. In between the tests we rebooted so that Windows would not save any files to memory and spoil our test results.
The results here reflect the trend of HDTach for the most part. When we transferred 1.87GB of pictures and video to the cards (write test), the Soultek beat the Crucial card by 1:45. A noticeable margin for sure. When writing these files to our hard drive (read test) the cards performed much better. The Crucial card still came is second though - lagging behind the Soultek card by 0:44 seconds. Truly the 150x Soultek card is faster that Crucial's regular 2GB card. Not really much surprise because Crucial rates their card at a minimum of 20x.
While Crucial's 2GB card is clearly not as fast as Soultek's 150x card, it is plenty fast enough for today's digital devices. A 7MP camera writes a high quality JPEG file that is around 3.5MB. The card is fast enough for this file to be written is less than half a second. It really shouldn't slow you down at all. If you are looking for the fastest card of the two though, Soultek would be the way to go. That being said, Crucial is excellent about product warranty, and if something ever happened to the card, they'd be a lot better to deal with in my opinion. There you have it. Both are good cards, but the Soultek outperforms the Crucial 2GB SD card by a fair margin.
I would like to thank Crucial for sending over this card for me to use in my other review as well as this one. They are a great company to do business with for sure.
