Founded in 1988 by Dr. Eli Harari, an internationally recognized authority on non-volatile memory technology, SanDisk has grown to become the world’s largest supplier of flash memory data storage products.
Serving both consumers (via over 100,000 retail storefronts worldwide) and original equipment manufacturers (OEMs), SanDisk designs, develops, manufactures and markets flash storage card products for a wide variety of electronic systems and digital devices. SanDisk also licenses its technology to a number of other industry-leading companies.
I will be reviewing today SanDisk Memory Stick PRO Duo 1GB that’s a mouthful. It comes in as you can see in a small neat package and the memory card is coloured in neon green. The PRO Duo also comes with its own protective case when not in use.
The Duo as I will call it in the review is very small as you can see in the picture next to a 1 penny piece for size comparison, the actual size is 3cm by 2cm. The stated memory size is 1GB but when it is formatted this is around 949 MB in size, which is still plenty to store pictures of vary sizes from the usually 3 Megapixels up to 5 Megapixels range.
The Duo can be used in most Sony products that can accept the card as is or in an optional caddy as seen below.
Here is a list of where the DUO can be used ranging from:Sony PSP
Digital Video Camcorders
Digital Cameras
Laptops
On the card you will find four folders and in the PSP folder you will find subfolders which are used for the Sony PSP held hand system to store pictures and music and game data.
The test
I will be running real world tests using image files of different sizes to determine how fast it can read and write. The test will be run three times to workout the average read and write speed. On with the test.
Test 1
Transferring 50Mb to the Sony digital camera using a USB 2 cable
40 secs
40 secs
39 secs
Average speed is 39 seconds to transfer 50Mb of image files.
Transferring 50Mb from the Sony digital camera using a USB 2 cable
18 secs
6 secs
6 secs
Average speed is 10 seconds to transfer 50Mb of image files.
Transferring 100 Mb to the Sony digital camera using a USB 2 cable
1.15 min
1.15 min
1.15 min
Average speed is 1minute 15 seconds
Transferring 100Mb from the Sony digital camera using a USB 2 cable
37 seconds
36 seconds
37 seconds
Average speed is 50 seconds
Obviously the smaller the file size the quicker it is to transfer from the camera to the PC and vice-versa and longer when larger files are being transferred. We also ran 500Mb video file from the camera to see how it would run we saw no playback stuttering at all. This can be contributed mainly to the USB 2 connection and also the transfer speed of the memory card.
Conclusion
SanDisk have produced another winner in their long line of producing memory cards ranging from Memory Sticks for Sony products, SD cards, Compact Flash and miniSD™ and so forth.
I give it a 4.5/5.
