Storage Options

eMMC onboard

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.

S-ATA

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.

μSD

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 2260 size.

It is possible to place also modules in 2242 and 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.
