Quick Answer: How many drives can a sata cable support?


Can I use SATA cable for multiple drives?

Can I connect multiple hard disks to a single SATA slot on the motherboard? No, not directly. Your only options are to use a port multiplier or to add additional SATA or SAS connectors.

How many SATA drives can be connected to a SATA cable?

Even though you can connect only one SATA drive to one connection, there are typically six SATA connections available on most computer motherboards. Doing this work yourself is not very difficult, and can save you money and time, as you won’t have to do without a computer while a technician installs the drives for you.

How much power can a SATA cable support?

The ATX standard for SATA or Molex connections is rated for 54 watts. Each SATA/Molex connector provides three 12v pins at 1.5 amps each, for a total of 4.5 amps.

How many drives does a SATA port have?

Normally 1 drive per port. You can get “SATA multipliers” to attach multiple drives per port, but you do so at the cost of channel throughput.

Can I split a SATA port?

SATA is a 1 device 1 port thing. You can‘t split it like a USB.

Does it matter what SATA port I use?

If you are installing a single SATA hard drive, it is best to use the lowest numbered port on the motherboard (SATA0 or SATA1). Then use the other ports for optical drives. Then use the next lowest numbered port for the second drive, and so on.

Can I put 2 hard drives in my computer?

There are two main ways to use multiple hard drives on a single computer: You can connect multiple external hard drives to a laptop or desktop computer using a USB or Firewire connection. The hard drives store data in combination or mirror one another to back up duplicate data on multiple hard disks.

How do I connect two SATA hard drives to my motherboard?

Plug one end of a SATA data cable into the smaller L-shaped connector on the hard drive, and plug the other end into one of the SATA controllers on your computer’s motherboard. The SATA controllers are usually labeled SATA1, SATA2 and so on.

What can I connect to a SATA port?

SATA is a connection type used by computers and computer-like devices to connect peripheral storage components like optical drives and hard drives to the device. SATA replaced the parallel ATA standard.

Do SATA hard drives need a power cable?

For 3.5 Inch Desktop Hard Drives the power cable and the SATA cable are separate cables. Every recent power supply should come with a few SATA power plugs. You’ve noted that the HD is SATA, so you will need a SATA cable between the motherboard and the drive, and a SATA power cable from the power supply to the drive.

Is it safe to use Molex to SATA adapter?

Safe, yes. Usable, not necessarily. A Molex to SATA connector should be fine for most HDDs and DVD Drives but it may not be sufficient for more modern SSDs and BluRay drives. The SATA power connector includes a 3.3 volt rail as well as the traditional 5 volt and 12 volt rails.

Is it safe to use SATA to 6 pin?

No. If the GPU you use doesn’t draw much power from riser it’s probably safe otherwise it’ll draw more powder over the sata cable than it’s meant for.

Can you add SATA ports to motherboard?

You can get PCIe SATA Cards (RAID controllers also often have SATA Ports as well). PCIe slots are wired straight to the motherboard or CPU; PCIe to SATA add-in cards are quite common and the traditional way to add more storage. PCIe slots are just that: an extremely fast interface to add input/output to a motherboard.

How many hard drives can a PATA cable support?

PATA is a good example of a drive technology that supports up to two devices per motherboard interface. There’s no common hard drive interface type that has a maximum of four devices per interface, although SCSI can easily support four drives on a single interface.

How many hard drives can be connected in a single SAS cable?

A typical SAS card may have just one or two connectors on it, and on its own would only be able to support up to four or eight drives. A setup using SAS expander enclosures can allow a controller to use up to the maximum devices it can support, which is typically 128 or 256 devices depending on the card.
