OCZ Gold Series SDHC
Feb 16th, 2009 | By SimonATTO Disk Benchmark
ATTO Disk Benchmark is a commonly used program by manufacturer to gage how fast a drive reads and writes. With the OCZ Gold Series, we’re off to a good start with the memory card peaking out at 11.4MB/s write and 20.2MB/s read. The 20.2MB/s read speed is lower than the listed 22.5MB/s transfer rate for 150X however the 11.4MB/s write speed far exceeds the minimum class 6 of 6MB/s.
CrystalDiskMark
CrystalDiskMark is another synthetic benchmark that determines read and write speeds for sequential performance, performance with transfer sizes of 512KB and with 4KB. The results are very similar to those from ATTO.
HD Tach RW v3.0.1.0
HDTach gives us our first look of performance from start to finish. The drive almost consistently write at 12MB/s and reads at 20MB/s. There were a few hiccup that caused the read and write performance to take a small dip. HD Tach RW also shows our CPU utilization to sit at 3% and gives a random access time of under 1ms. Both numbers are very respectable.
HD Tune
Our final synthetic benchmark is HD Tune. It does essential the same thing as HD Tach and the numbers are identical.
From the benchmarks we’ve seen, the OCZ Gold Series has consistent read and write performance. When I put the 8GB OCZ GOld Series SDHC card inside my SD880IS I was pleasantly surprised by the write performance the card offered in real world testing. I set the camera up to shoot at the highest resolution (3648×2736) and at the superfine level. The card was able to hold 1824 photos at this setting. At the lowest resolution, 640×480, the card holds over 10,000 photos. Each picture at the highest resolution and detail was 3.382 MB and with continuous mode I never had to wait for the camera finish writing on the memory card before being able to take another photo. I fired off 200+ photos before getting tired of holding down the button. When I tried the same test with the original OCZ SDHC card, it would occasionally flash a “busy” icon indicating the buffer is getting full but still the pictures only slowed down for a split second before going right back into rapid fire. The camera shoots at approximately 1.4 frames per second on continuous mode.
After formatting the 8GB OCZ Gold Series SDHC for my Samsung SC-MX20, I was able to store 4 hours, 4 minutes and 54 seconds of video. The battery was only good for 164 minutes!
