+= mSATA (SSD) / SATA / Storage =
+Several Gateworks products support SATA and mSATA.
+
+For microSD card support, see [wiki:ventana/simsd here]
+
+
+== mSATA ==
+mSATA cards are miniPCIe form-factor (electrical and mechanical) cards that use SATA signalling on the PCIe signals and typically use flash based storage (Solid State Disk or SSD).
+
+
+== Ventana ==
+'''Note''' - ''mSATA requires a quad-core processor on Ventana''
+
+'''Note''' -  ''For configuring, jump to [#VentanaSoftware]''
+
+Many of the Gateworks Ventana boards support mSATA. Because mSATA routes SATA signals to a miniPCIe socket, these boards use a software controllable mux to decide if mSATA or PCIe should be routed to a specific miniPCI socket on the board. The bootloader 'hwconfig' command (see [wiki:ventana/bootloader#mSATAenable here]) is used to configure this mux at boot time because if PCI is desired, the bus is enumerated only once at boot time.
+
+Ventana boards with mSATA support:
+ * GW5520-SP308 (IMX6Q) J6 (Bottom Left socket)
+ * GW54xx (all variants) J11 (Bottom Left socket)
+ * GW5304 (fully loaded with IMX6Q) J9 (Bottom Left socket)
+
+Notes:
+ * SATA II 3Gbps interface supports Mini-PCIe mSATA disk drive
+ * Gateworks would expect any SATA 3.0 mSATA to work
+ * Only 1 miniPCIe socket supports mSATA - see the PCB silkscreen or hardware reference manual to determine which (if not specified above)
+ * Drives are currently available from a variety of manufactures including Toshiba, Samsung, HP, Intel, !SanDisk and Dell.
+ * The selection between the standard PCIe interface and the mSATA interface is under software control using the i.MX6 GPIO[2]:DIO[8] digital I/O signal, which is configured by the bootloader on powerup via the '[wiki:ventana/bootloader#mSATAenable hwconfig]' command.
+ * Gateworks tests with a mSATA Crucial CT032M4SSD3 32GB SATA SSD: http://www.amazon.com/Crucial-mSATA-Internal-Solid-CT032M4SSD3/dp/B0082PVK8Q
+
+The internal IMX SATA controller supports the following features:
+ * Compliant with the following specifications:
+ * Serial ATA 3.0
+ * AHCI Revision 1.3
+ * AMBA 2.0 from ARM
+ * SATA 1.5 Gb/s and SATA 3.0 Gb/s speed.
+ * eSATA (external analog logic also needs to support eSATA)
+ * RX data buffer for recovered clock systems
+ * Data alignment circuitry when RX data buffer is also included
+ * OOB signaling detection and generation
+ * 8b/10b encoding/decoding
+ * Asynchronous signal recovery, including retry polling
+ * Power management features including automatic partial-to-slumber transition
+ * BIST loopback modes
+
+
+=== Ventana Software ===
+ * '''Note''' - '''' Please see the bootloader for configuring mSATA [wiki:ventana/bootloader#HardwareConfigurationhwconfig]''
+ * If configured correctly device will show up most likely as a device {{{/dev/sdX}}} in the operating system , etc (sdb,sdc,sdd,sde) (where sd stands for storage device and a is an identifier)
+
+=== Ventana mSATA Performance ===
+See the following link for some read/write performance numbers for mSATA SSD drives on Ventana:
+[wiki:boot_speed#StorageDevicePerformancenocodechanges]
+
+== Laguna ==
+Laguna has support for SATA on the GW2388 [http://www.gateworks.com/product/item/laguna-gw2388-4-network-processor]
+ * SATA Serial ATA 2.6 port
+ * The GW2388 includes a SATA factory ordering option. This option adds a Serial ATA data connector for supporting SATA 1.5Gbps Generation 1 and 3Gbps Generation 2 speeds. The SATA port is compliant with Serial ATA 2.6 and AHCI 1.1.
+ * Please consult the user manual for more information [http://www.gateworks.com/product/item/laguna-gw2388-4-network-processor]

+
+
+= PCIe based Storage =
+Various cards exist that implement a SATA interface over the PCIe bus.
+
+Some common examples
+ * Solid State Disk (SSD):
+  * [http://www.supertalent.com/products/ssd_product_detail.php?parent=6&category=CoreStore&type=104 Super Talent !CoreStore Plus] - ASMedia Technology Inc. ASM1062 Serial ATA based (similar to mSATA but actually uses the PCIe bus signally and thus does not require mSATA support)
+ * PCIe to SATA adapters:
+  * [http://www.sybausa.com/index.php?route=product/product&path=64_77_81&product_id=124&sort=p.price&order=ASC&limit=64 Syba 6G mPCIe 2-port] - ASMedia Technology Inc. ASM1061 Serial ATA based
