The Fusion-io ioDrive 80GB
The ioDrive is made in two halves, the first with the PCIe data connection and power circuitry. The second part holds the memory modules and controller chip that is passively cooled.
There is not much going on along the back of the card other than a lot of NAND memory.
The back side of the card is fairly straight forward as well. The LEDs show the status of the drive.
Our sample used Samsung memory that was double stacked. As you saw in the previous images, there are quite a few memory chips onboard.
If you look closely you can see that for every visible memory module there is another under it.
