You could buy a 4-port SD card hub for ~US$63.
However, you could easily make your own: SD card readers are available for less than $US2, and a 4-port USB hub for ~US$6, so you could assemble a similar 4-SD card hub for
You don't state your purpose, so it's hard to understand what you need.
If you're trying to make copies of SD cards, e.g. as OS for a ...
It's going to be very difficult to find a quad port SATA controller that does not have RAID capabilities built in so you might as well get it with RAID and just not turn on that feature. It is nice, however, to know that you can go RAID if you want to later down the line.
That said, I would stay away from the smaller brands that don't have a strong ...
I'm not sure about their software, but being a company specialising in this presumably QNAP has good software support.
One device which I presume will meet your expectations is the TR-002 which has two 2.5" bays. They even post a test result using 2 x Samsung 850 Pro. Should you be interested there is also a four drive version.
I don't have experience with ...
For $100, you're not going to get a new card. New hardware RAID cards typically run several hundred dollars. What you can get is an old server-class RAID card pulled from a retired system.
I recommend the Areca ARC-1120 8-port card. It's a universal PCI/PCI-X card, so it can fit in almost any PCI or PCI-X slot (the exception being those few PCI ...
Unfortunately, there seems to be a lack of higher-bandwidth SATA controllers. The closest I can find are PCIe 2.0 x2, which is available on some StarTech cards. They are based on the Marvell 88SE9220/88SE9230/88SE9235 controllers.
Given the lack of SATA options, the next best avenue is a SAS HBA, which supports SATA drives when the appropriate cable is used....
SATA 1 150mb/s
SATA 2 300mb/s
SATA 3 600mb/s
If the RAID controller has SATA 3 connectors it should be able to handle it. If you are looking for raw speed a samsung ssd will do 500-550mb/s read and 300+mb/s write beating any 2 hard drives you can attach via SATA.
I personally like the LSI (now Avago) brand of products. They are actually an OEM for IBM, Dell, Fujitsu, HP, and (when they made Xserve) Apple.
There's a really good HCL (Hardware Compatibility List) on FreeBSD's website that list all the compatible HBAs.
The card that I would recommend that hits all of your points is the 3WARE Sas 9750-8I. This is ...
