Sata how many drives per port




















That is what I do at the moment Hennes Hennes Overview Here's a graphic detailing what I've found. Port Multiplier What you're describing sounds most like a port multiplier here and here. USB 3. Other References Similar question on tomshardware. Of course, the reason you didn't do this was that the linked question is a duplicate of this question.

Ramhound This is a pet peeve of mine with duplicates. The questions are marked as duplicate, but the answers are not. It seems like the answers should be merged. The answer I posted is an entirely valid answer to the OP Ramhound Also, in my experience, the best answers present and compare all reasonable answers. To me, the two contestable answers are 1.

Yes, you can fork SATA data, but it's a hack and 2. Just use a PCIe, which is a good alternative but not always an alternative, and it's clear the OP was looking for something else here. Quality QA isn't just about raw information, but very much about how that information is presented.

If you want to submit your own answer, I am all for new answers, just not answers that say "well this is a duplicate of this question, here is the answer from that duplicate question" because that isn't helpful. Links are broken, probably do not use links to items in shops.

Thanks for linking the duplicate. Ramhound is right from the robot point of view. But user seeking an answer does not care if an answer is a duplicate of a duplicate question, when such duplicate would not reach this user.

There is a link so it's not plagiarism. They instead use the M. If you do have an M. In this next category of users, we have people who want to leverage their SATA ports for more than two or three drives. This can be as a measure to improve the storage capacity of the computers or to create a personal media server.

Users who need to use multiple drive bays will often want some of the hard drives to be used as backups in case one or more of the hard drives that they have installed fails.

Their size and the price is determined by a few factors:. So, to be on the safe side, ensure you take your needs into account. A safe bet is to always go with three or more ports.

The amount of SATA ports you need depends upon a lot of factor. When DMA data is to be transmitted and is received from the higher command layer, the transport layer appends the FIS control header to the payload, and informs the link layer to prepare for transmission. The same procedure is performed when data is received, but in reverse order.

The link layer signals to the transport layer that there is incoming data available. Once the data is processed by the link layer, the transport layer inspects the FIS header and removes it before forwarding the data to the command layer. In the end, what is left parallels the PATA type register based information. SATA uses a point-to-point architecture. The physical connection between a controller and a storage device is not shared among other controllers and storage devices.

The multiplier performs the function of a hub; the controller and each storage device is connected to the hub. This Legacy Mode eases OS installation by not requiring that a specific driver be loaded during setup, but sacrifices support for some vendor specific features of SATA. Often, which ports are disabled is configurable. The consortium has made several revisions to SATA standards to reflect increased data transfer speeds.

The M originally stood for mini, but that designation is no longer made and the specification is referred to as mSATA. This CF card is not compatible with standard CF card slots. Its use is so far not wide spread. AHCI mode is by far the mode used. The specification details a system memory structure for computer hardware vendors in order to transfer data between system memory and the device.

In principle, Native Command Queuing is relatively simple. Speed is increased but there is also an impact on power consumption and noise level which is reduced. Another possibility in using NCQ is multitasking in the case where you run two very heavy simultaneous drive access applications. To better explain this situation, imagine an elevator, in which two people enter simultaneously on the ground floor.

The first pushes the 12th floor button and the second the 2nd floor. It would be counterproductive to go to the 12th floor and then to the 2nd floor. New posts New profile posts Latest activity. Current visitors New profile posts Search profile posts Billboard Trophies.

How many ports do SATA cards go up to these days? Looking for recommendations Any answers, thoughts and comments on this would be appreciated.

Jul 10, 6, 2 27, Basically, yes. 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. Depends on the board, but 6 or more is a fairly standard number. One of those is normally used for the optical drive. The cheap adapters often have two ports, for more money you can buy adapters with up to 8 or even 16 ports. SATA is designed to be backward compatible, and the port and drive will autonegotiate the fastest speed supported by both.

Occasionally you get a combination of chipsets that don't play nice, so the drives usually have a jumper that forces them to a slower mode to bypass the negotiation phase. Yes - but I don't have experience with them so I can't give you a recommendation. I will warn you, though, that a drive RAID-5 array is generally not a good idea - the unrecoverable read error rate of a lot of drives means that you're fairly likely to get yourself into a situation where you loose data even with the redundancy.

Feb 20, 0 18, My JMicron and Intel ICH10R are but a few that can allow multiple drives to be connected if using a backplane or multiple harddrive docking station. Can't remember how many they will detect off the same port but as sminlal already mentioned throughput is limited to the ports native speeds.

You can however run a hardware raided pair of fast HDD through a single port without hitting the sata2 limit. Rusting In Peace Distinguished.
