How much power does this thing take? I'm thinking of buying one for a Raspberry Pi, but it only accepts 3.3V for SD cards.

Sorry, but I cannot answer that question. I'm not an expert on electronics. I'm using this 8GB SD card just for my 2011 Nixon 16p camera. Hope that you will find a better response.

As per http://www.sandisk.com/products/ssd/sata/standard/ it consumes 50 mw - as per my knowledge it is .05 v - should be OK.

First, let me say; I am a very "Low Tech" redneck....I always assume, if an "SD" card will fit, it will operate.I am using the cards I bought in a desktop computer, and have no problems so far...

You're probably considering this device because it has its own external power supply, which prevents your Raspberry Pi's power supply from becoming overloaded. Right? I just got this device in the mail today and I had no problems hooking it up to my Raspberry Pi 2 and reading some of my existing hard drives. I found the disks with "sudo fdisk -l" and they show up as /dev/sd? devices. I did have a problem with a few drives mounting in read-only mode. This is more of a Raspberry Pi problem (not having the correct drivers). To get around this, I had to do the following: "sudo apt-get update" "sudo apt-get install ntfs-3g" then a command such as "sudo mkdir /sda2" "sudo mount -t ntfs-3g /dev/sda2 /sda2" You can find other documentation on-line, like how to get it to automatically mount at boot with /etc/fstab entries. Mine is "/dev/sda2 /sda2 ntfs-3g defaults,noatime 0 2". The "noatime" tells it not to constantly update the directory attribute to record each time a file is accessed. But back to your core question -- yes, it absolutely works great with a Raspberry Pi 2 (and by extension, shouldn't have any problem with Raspberry Pi 1 Model B+, and probably other version as well). Enjoy!

I looked up the power requirements for Rasberry Pi and it looks like this might be a good power source but the amperage has to be within a certain range and that part is not clear. The ICarrier has 5 volts so that part should be fine. If I were you I would call the friendly folks at New Trent to clarify. Good luck.

No external power required. Only needs a USB port with enough power. Most standard USB 3 ports should be adequate.

I have not used it for such, only using it with a Raspberry Pi which has limited power capabilities from its USB ports. Check the documentation but I believe the total power limit for this device is around 2 amps, so you need to determine the power requirements of the drives. Further, there are only four ports on the device so without further extenders (it's frequently a bad idea to add USB extenders onto to USB extenders, I've heard stories of problems) you're limited to four devices. I do believe there are 8 port powered USB extenders available as well. You might want to investigate one of those. But first determine the total power requirement of your drives.

Depending on what you put inside it, you might need USB 3.0USB 3.0 can supply much more power than USB 3.0And now there is even USB 3.1

I'm not sure how you would actually measure it. I can tell you that they run 10 ASICMiner Block Erupters without issue, so they meet the USB 2.0 spec of 5V/500mA per port. I suspect it would have a hard time with meeting the true USB 3.0 spec of 5V/900mA per port, but it would be close.

Actually the manual does mention that an external power adapter is available if the attached device needs more power than the ExpressCard can supply. It's on page 2. Frankly, it seems to me, the vast majority of people will be better served by running the supplied USB 3.0 cable from the card to a powered USB 3.0 hub. This avoids any power issues in the first place.

Well they say 440 watt however I myself have been using it on a system with 230 watts power supply with no issues. Just note I am not using any extra internal or external devices beyond what the computer came with other than this card...so no external USB's etc...hope that helps

The spec sheet says the minimum power requirement is 300 watts for the system and 65 for the card, so it would seem your system is right on the edge.

I can plug it directly into a USB port but just to provide power I believe you still need to use the SD card

I don't know if it'll work with out the ac adapter. I do use it to run a Raspberry Pi, without any other power source so I would assume yes.

I am not sure about the power requirements for that, but it is a high quality item. My initial thought is that it would do that without any issues.

Can't answer that since it would most definitely depend on what other components you have. This card does not require a lot of power by design, but the total power load would depend on the other components in your system - not just this card.

I know they require a lot of power, I can't tell you the exact amount. I would definitely buy a powered USB hub.

if you're asking about the card itself - no. It gets powered by the PCIe bus. If you're asking about the devices plugged into it - it all depends. If you're trying to run something that requires 1 Amp @ 12 VDC - then you need an external power supply for your device. If you're trying to run a SSD/HDD in an external box - then the card on the bus power should power up your device reasonably well.

I purchased one from another site. It came with a 5 V 2 A regulated wall wart type power supply in the factory blister pack. My unit is one of the few that works well with Raspberry Pi.
