A-data is about 4 years old, and has had little in the way of publicity.  Red & Blackness Mods sheds a little light on their very stable DDR-667 Vitesta DIMMs.

"We met up with A-data at Cebit and got a cooperation started, and here is our first review of

one of their products. They sent us a kit of their new DDR2 ram, with the DDR2 market growing

fast and replacing the DDR memory this is a great product to review right now. We will compare

this to our previous DDR2 memory kits we have reviewed in the past and we will also share

stability and overclocking results with you."
