Rosewill RC-218 PCI Express x4 (x8 and x16 slot compatible) SATA II 3G Controller Card/ 4 internal SATA with 2 external eSATA Design

This card is 4 channel. I did not look at the picture of the front of the box when I bought it, and was dismayed when I got it to find out that it has 6 ports, but only 4 can be used at a time. I will likely be trying a different card soon because I...

This card advertizes with 4 internal and 2 external ports. All ports work, and I have had no problems after installing this card in a FreeNAS box where I needed to add a few drives

This is pretty minor, but the pinout on the jumpers were a little difficult for me to mess with. To change over from using all four internal ports to using 2 internal and 2 external requires the moving of 8 jumper shunts. A larger block type mega-shunt...

Would be nice if Rosewill made a 8-port PCI-E x8 card.

Awesome card for Linux RAID. Very fast transfer rates, card works right out of the box

Cant use locking SATA cables due to the way the ports are laid out. You can always grab a pair of needle nose pliers and remove the locking tab from one end of your SATA cable

Required 4 additional SATA ports for a file server, had a x16 PCIe port open, so this fit in well using 4x mode (each SATA port has it's own PCIe lane.) Transfer speeds are acceptable (2x drives are SSD's, 2x are SATA II HDD's), and have had NO issues...

Spent a little time trying to figure out why, on Boot, only 2 drives appeared (tried 2 PC's, switching drive ports, wasted ~2 hrs messing with it.) ; I finally found a review here that indicated only 2 drives appear on boot in the Card's BIOS screen,...

Used this to add SATA ports to a computer I pieced together from old parts. Works great! Based on other reviews, I didn't attach any optical drives to it.

Fairly easy to install. Latest Arch Linux (as of this writing) had no problems recognizing it. SATA II ports seemed to be even faster than the on-board ports they were supplementing

Minor cons: ports were close together, but manageable. As other reviewers said, the ports don't have latches for the clips on certain SATA cables, but unless you're installing the card in a machine that moves or vibrates a lot, this shouldn't be a problem

Have bought 3 of these - all have worked flawlessly

Adds 4 SATA-II internal ports ; Provides true PCI-Express x1 lanes for each sata port ; No issues with Ubuntu 11.10 ; No issues on Supermicro MB ; No issues with multiple cards on same MB ; Low power usage

None

Make sure this card is seated as straight as can be! Glad it came with a low profile bracket. A little upset w/ Newegg because this card went on sale for 50% off a few weeks after I bought it.

Great card; it does what it says it'll do with very little trouble ; Requires nothing from the user after initial setup ; Comes with low profile bracket, which was a plus because I installed it into a rosewill server case ; 4 internal SATA ports for a...

Not worth taking an egg off for, but I couldn't figure out why the server I installed this on would not boot while my two SATA drives were plugged into this card. I tried the onboard raid controller that came with my motherboard, which worked fine so...

Bought two of these to make a RAID using Linux software raid. Got this because its a x4 PCIe interface which give much better throughput than a x1. Its hard to find a x4 card without RAID functions, which interfere with useful things like SMART data,...

Works great in Linux. Hot swap works. Able to read SMART data. Supports 3TB drives. Gets great performance (~350MB/s with two 3TB 7200rpm drives). No stupid quasi-RAID functionality

Only comes with two SATA cables

You get what you pay for, not much.

It plugged in

it didn't work, I can get one drive to show, after trying six different drives. Oh yeah, good times

If need to just add 4 more ports for hard drives (JBOD), then this is what you are looking for.

Simple and no fuss way to add 4 sata HD ports. Inserted card with 3 Samsung HD204UI drives connected. With Win7 x64, it automatically detected and installed Sonnet drivers (be sure to be connected to the net). All drives working fine. No need to...

BIOS only displays devices on first two ports instead of all four. Non-configurable. No connection for HD light

You can only connect FOUR devices to this, even though it has SIX ports. The product page explains this, but I figured I'd mention it again since some people are surprised by this.

I've used this successfully with Fedora and Ubuntu Linux without any extra drivers or fuss. I just had to put in the card, connect four 2TB drives, and boot. Sweet
