Hello, is it possible to use SATA / SATA II for embedded systems ? At the moment i have almost no info about SATA, so please forgive my general questions. The SATA connector looks fairly simple (reference see below), only 4 data lines needed plus 3 ground pins. Is it needed to use the high speed of 1,5 GBit/s or 3,0 GBit/s or can i use the much slower (in kHz area, which a uC can ge...

Hi there, Before I post my problem, let me present the overall picture. We have developed a realtime embedded data acquisition system based on A/D, FPGA, SATA controller, SATA HDD, microcontroller and Ethernet. The purpose of the system is to record seismic data from the sensors, digitize them and write them on the SATA HDD. Later, the recorded data can be retrieved through Ethernet. We hav...

The company at which I am working have finally decided that they need to log data from their equipment, which has an interface that is mechanically compatible with SATA, and could implement a 3Gb/s SATA 2 interface. Reading the Seagate Barracuda 7200.11 datasheet at http://www.seagate.com/docs/pdf/datasheet/disc/ds_barracuda_7200_11.pdf I note that the "Sustained Data Rate OD" is between 105MB/...

Been doing a lot of stuff recently that requires 3.3V and 12V at moderate currents. The simplest commodity way to do this seems to be a PC power supply. The 24 way ATX connector is a bit clumsy and you only get one per PSU, so it seems simpler to use SATA connectors as a handy ecosystem of 3.3/5/12v power at up to 4.5A per rail. A scattering of these provides the necessary few hundred watt...

Does anyone know if it's standard practice for motherboards to put SATA hard drives in standby or sleep mode when they are shut down? I would like to leave the drives in a system I'm designing permanently powered, but this will only work if they are shut down with the motherboard. I couldn't find anything useful with Google searches and I haven't heard back from the motherboard manufactu...

I am trying to start using SATA drives in a system with a SOC chip which only has parallel ATA. Got some adaptors (3 of them) from dealextreme and thought I'd just connect things to work initially. All based on the JM20330 part, found its datasheet, thought I'd route a board revision with this chip instead of with the ATA buffers eventually, lets first see how things work. Or do not wor...

Hi, Two of the projects I am working on require metric buttloads of secondary storage. Some for online use, even more for offline/archival purposes. I've been using external USB drives so far. Buying more of these just doesn't *feel* right (why am I buying cases, controllers, power supplies etc. when I just need the *drives*?) So, I'm in the market for some 1-2T drives, SATA no do...


SBC with ADC, 1GE, and SATA2?

I'm lokking for a small (4x6", 6x8", range) SBC that has a reasonably good A/D converter (100+MSPS), at least one 1G ethernet, and one or more SATA-2 ports. I'm not picky about the processor. Anything that runs Linux or an FPGA would be fine. A nice option would be an LCD and keypad interface. Has anyone got any recommendations? All of my Google queries are possessed! I keep getting the s...
