A-DATA 16GB Turbo SDHC Class 6 Memory Card

Received the SDHC card rather quickly, but no reader. After three phone calls and 2.5 weeks finally was shipped a reader from seller but not the reader advertised. Long hard believer in don't say you got it unless you do and can ship quickly. Card works great in my Kodak Z1485IS.

this card is the deal ! the price is perfect, I use it to capture hd video without any problem

This is a great card for capacity, price, and read speed, but not a very fast writing card, at least the item I received.

It seems like flash memory is very hit or miss these days. It has amazing read performance, often around 20MB/s. Unfortunately, the write speeds (the most important for digital camera usage) are not up to par. When writing to the card, transfers start somewhat slow, 3-4MB/s, and accelerate up to 6-7MB/s (above the Class 6 spec of 6MB/s) after about 10 seconds of writing to the disk.

In camera (Panasonic LX3), on continuous burst, the camera starts fast, for about 15 shots, but slows down dramatically after that to about one shot per second (the images are ~4MB a piece). As a comparison, I bought a 2GB class 4, SanDisk Ultra II and I get only 15MB/s reads, but 12-13MB/s writes. This card records many more images in burst, so many that I stopped recording before it slowed down, >50 however. My card is fast enough to record 720P motion JPEG video from the camera for at least 2 minutes continuously (I did not test beyond that time).

Finally, further benchmarks reveal that formatting as exFAT with 16 kB allocation unit size provides optimal performance (FAT32 with 16 kB blocks was basically identical, which is good as not many devices suppport exFAT).

Realistically, this card is fast enough for almost any usage, but it is disappointing that a year old SanDisk Ultra II 2GB card (Class 4) is twice as fast in write performance.

I purchased this for my panasonic lumix tz3, and it works great, Out of the box, into the camera, and I have the capability of 5200 photos at 6mp in 16x9 format. Not to shabby, also around 120 minutes of recording time, a nice plus. I have seen no issues with it's speed or performance in comparison to my 4gb transcend card I have. Currently recommend this to anyone looking for a good value.

It could not keep up with recording HD material on my Panasonic Lumix TZ5 digital camera.... I feel ripped off...
