Need more sata ports... Pci?

post #1 of 3
Thread Starter 
If this is in the wrong subforum, please let me know or move it accordingly.

Like the title says, I'm looking to add more Sata ports to my rig. Preferably sata III. My x16 port is being used for my gtx 970 and my x8 slot is covered by the gfx card, but I have an x4 and an x1 ready for use. Searched around but can't really find a rock solid answer. Would like at least 4 extra ports. Saw a few syba cards but the reviews were mixed, and most didn't note compatibility with win 10.

Not PCI-E but PCI? The most common PCI controllers use the VIA VT6421A chip and have 2 SATA ports and 1 PATA port. Avoid the older VT6421 and VT6421L chips, which require drives to be limited to 150 Mbytes/sec or slower. eBay typically has VT6421A-based cards for $7-10, delivered. The other choice is something that uses a Silicon Image chip, such as the SiL3112 or SiL3512 (2 SATA ports) or SiL3114 (4 SATA ports). All of these cards can boot from optical drives, unlike the Promise-based cards, but none can use drives bigger than 2TB.

A PCI port has only the equivalent speed of a PCI x1 slot (one lane), if that. Each lane of PCI-e has only 5Gb of bandwidth (SATA III is up to 6Gb). Assuming your board is using only the 24 lanes the two cards you already have are using (many boards use PCI-e lanes for USB 3.0, etc., making them unavailable for your use even though you have open slots), you would get nearly full bandwidth from an x4 card in the x4 slot for only four SATA drives (HDDs haven't saturated SATA III speeds yet so the slight reduction will not be noticeable). The x1 slot will support nearly full bandwidth only on cards with one SATA port. There are a lot of x1 cards that have more than one SATA port; stay away from those.
