Depending on the chosen model of UDOO X86 you could have an embedded multi media card memory up to 32GB to install your favorite OS.
The eMMC use a SD 3.0 compliant interface.
Heads up! As a flash-based storage device, excessive drive access, particularly write commands, reduces its useful life. Therefore, it is strongly suggested to NOT create a swap partition on the eMMC device.
The N-series Intel® Pentium® / Celeron® and x5-Series Atom SoCs embed a SATA Controller, which offers two SATA III 6.0 Gbps interfaces.
Of these interfaces, one SATA channel is carried out to a standard male S-ATA connector, CN18 (the other SATA channel is available on the M.2 Key B socket).
A dedicated power connector (CN21), can be used to give supply to 2.5" Hard Disk Drives (or Solid State Drives) connected to the SATA male connector.
The dedicated power connector is a 4-pin male connector. You can find this cable in the SATA data and power cables for UDOO X86 kit.
Heads up! To connect a 3.5" Hard Drive you need to provide SATA +5V+12V combo power supply from an external source.
The SoCs used on UDOO x86 module offer a SD 3.0 compliant interface, that can be used to implement another mass storages media other than the optional internal eMMC and the two SATA interfaces. This SD interface is carried to a standard μSD card slot (CN17), soldered on top side of the module, push-push type.
Heads up! Due to a UEFI BIOS bug you couldn't be able to write data on the μSD connected. A bugfix is already released in the latest official UEFI BIOS version (1.02). Make sure to keep updated the firmware of your UDOO X86 using the UEFI update procedure.
M.2 SATA/PCI-e Slot: Socket 2 Key B type 2242/3042/2260
The mass storage capabilities of the UDOO x86 are completed by an M.2 SSD Slot, which allow plugging M.2 Socket 2 Key B Solid State Drives with SATA interface or PCI-e x2 interface (PCI-e x1 is also supported).
The connector used for the M.2 SATA/PCI-e slot is CN20, which is a standard 75 pin M.2 Key B connector.
On the UDOO x86 board there is also a Threaded Spacer which allows the placement of M.2 Socket 2 Key B SATA/PCI-e modules in
It is possible to place also modules in
3042 size, by using a M/F Spacer which allows fixing the M.2 module on the spacer already available on the PCB, deemed for the fixing of the M.2 Wireless module.
