View Full Version : SD card speed with Pocket Mechanic

I have a new Jasjar and the package came with a 2GB SD card. The supplier tells me it should be a 60x card but in Pocket Machanic the benchmark says it is 4x on read and just 0.2x on write.

This is my one and only SD card so I have no others to compare. Is it possible Pocket Mechanic uses a different measurement method and that program just gives low figures for all SD cards? Or is my card really a slow one?

Can someone with PM give me some benchmark figures for their SD card so I know whether I have a slow card or not.

And should I expect a 2GB card to perform more slowly than say a 1GB card?

On my Exec using a 4GB 150X Transcend card, I'm only getting 0.7MB/s read and 0.2MB/s write (benchmarked by PocketMechanic)

Like in most other PPCs and PPCPEs, the SDIO interface is low speed so no matter how fast your SD card can run, you'll be limited to the speeds of the SDIO interface on your Universal.

Good observation O2. Actually I find it a bit surprising the Universal would have a slower than normal SDIO interface. After all it is just about the most expensive (if not THE most expensive) PDA/phone available. I guess I expected better - er, if that really is the cause of our slow SD card performance.
