Patriot Memory LX Series 32GB SDHC Memory CardDec 9th, 2009 | By Simon
I tested my Patriot Memory 32GB LX Series card with my Canon SD880 IS digital camera. This is a 10.0 Megapixel camera and with the largest resolution and highest level of detail, I was able to shoot 7193 pictures. Even if I managed to take 200 pictures a day, this memory card would be adequate for over a month!
Sliding in the memory stick into my Samsung High Definition Digital camcorder, it indicated that I could record 292 minutes at 1080p. The large capacity will let me capture a vacation or any special occasion without having to change memory sticks.
With digital cameras and camcorders it is hard to determine if the LX Series is actually capable of sustaining 10MB/s sequential write so I’ve called on a few applications to gauge the performance. First we’ll use Crystal Disk Mark where I will set the test file to 1GB.
Moving on, I will use IOMeter. IOMeter is an I/O subsystem measurement and characteristic tool for single and clustered systems initially designed by Intel.
IOMeter is both a workload generator (that is, it performs I/O operations in order to stress the system) and a measurement tool (that is, it examines and records the performance of its I/O operations and their impact on the system). It can be configured to emulate the disk or network I/O load of any program or benchmark, or can be used to generate entirely synthetic I/O loads. It can generate and measure loads on single or multiple (networked) systems.
I configured IOMeter to create a 1GB file on the target device, Patriot Memory 32 LX SDHC, and it will pull the performance over 5 minutes and report back the average transfer rate for various block size transfers: 4KB, 16KB and 32KB.
Both Crystal Disk Mark and IOMeter only test a portion of the drive and in order to see the performance from start to finish I switched to HD Tach for the final benchmark.
As you can see, Patriot Memory lives up to its claim of being a Class 10 drive. Based on the numbers above, it would even qualify for Class 15!
