An anonymous reader writes "ARM Holdings has made available Linux kernel support for AArch64, the ARMv8 64-bit architecture. No 64-bit ARMv8 hardware is yet shipping until later this year, but ARM has prepared the 36 patches amounting to 23,000 lines of architecture code for mainline integration."

Do you realize that the chip on the other end of a SATA link - typically the controller in the SSD you're using right now - has a lot of chances to be an ARM chip ? It is the case for common SSD disk controllers (Marvell or Sandforce).

And even if it is not common in today's products, there are a lot of recent high-level ARM SoCs that offer SATA - not least because its low pin count makes it easier to route on the board in the end than a parallel bus. For example, TI's OMAP5, Freescale i.MX53 or CSR's Prima 2 have SATA support.
