Hitachi Micro Drive 4 GB ATA-33 Hard Drive

Pros: works great until it breaks
Cons: Once it breaks you are done cost to recover data 300-1,000

If you are a photographer don't use a disk drive. Use only flash memory. I bought this card because the guy at the store said it was great. He was right until the drive failed. The pictures on the card are priceless to me and my client. The recovery of the data is not as simple as one would think and surely not cheap... Spend your money on a flash memory card as you will not have the headache of not knowing if you will ever get your pictures back...

Pros: great cost per gig
Cons: does not work well in extremely high vibration environment

Very cost effective flash card for professional photography. I have had good luck with this card. It writes fast and has a good cost per gigabyte. The only trouble that I have had is that it does not write well in a high vibration environment -like shooting with the camera out of an airplane window. Otherwise it works just fine.
