# Serial ATA (SATA)
|
|
|
|
Helios64 uses the JMicron JMB585 Serial ATA (SATA) controller to provide 5x SATA 3.0 ports.
|
|
|
|
|
|
|
|
The SATA Controller is connected to RK3399 SoC via 2x lanes PCIe 2.0 offering 10GT/s (8Gbps) of bandwidth.
|
|
|
|
## SATA Controller Features
|
|
|
|
- 5 SATA ports,
|
|
- Command-based and FIS-based for Port Multiplier,
|
|
- Compliance with SATA Specification Revision 3.2,
|
|
- AHCI mode and IDE programming interface,
|
|
- Native Command Queue (NCQ),
|
|
- SATA link power saving mode (partial and slumber),
|
|
- SATA plug-in detection capable,
|
|
- Drive power control and staggered spin-up,
|
|
- SATA Partial / Slumber power management state.
|

## SATA Controller Diagram
|
|
|
|
|
|
|
|
The above diagram shows the 2:1 MUX between SATA Port 1 and the M.2 connector. The M.2 SATA bus is shared with SATA Port 1, therefore if you install an M.2 SATA SSD card, SATA Port 1 (J3) will automatically get disabled.

|
|
|
## HDD Power
|
|
|
|
Helios64 provides on-board HDD power to supply up to 5x HDDs via header J7.
|
|
|
|
|
|
|
|
The power delivery of the HDDs is devided into two group:
|
|
|
|
* HDD Rail A (Max. 3x Drives)
|
|
* HDD Rail B (Max. 2x Drives)
|
|
|
|
Helios64 implements a power staggering approach where *HDD Rail A* will be powered up first, then few seconds later *HDD Rail B* will be powered up. This power control scenario is performed to reduce the inrush current during disk spin-up.

## HDD/SSD Harness
|
|
|
|
As part of Helios64 official enclosure, an HDD/SSD harness is provided to connected both SATA + Power signals between Helios64 board and the 5x HDD slots.
