Know your gear

The PEXMSATA3422 PCI Express SATA Card helps you improve the overall speed and storage capacity of your computer by giving you multiple 6 Gbps SATA connections for connecting high-performance SSDs (Solid State Drives) and hard drives in a HyperDuo array. Now, you can easily add two mSATA slots and two SATA III ports to your computer through a single PCIe x4 slot.

Featuring HyperDuo technology, the SATA card offers SSD auto-tiering which lets you balance the performance advantages of SSD storage with the cost-effectiveness and large capacity of standard hard drives. By combining SSD and HDD drives into a single volume (up to 3 SSD + 1 HDD), HyperDuo discreetly works in the background to identify and move frequently accessed files to the faster SSD drive(s) for improved data throughput - up to 80% of SSD performance! (Note: The HyperDuo automatic storage tiering feature is compatible with computers that use a BIOS.)

This versatile RAID controller card helps to relieve the internal space constraints often associated with multi-drive configurations by letting you install two mSATA SSDs directly to the card via convenient, latching slots. With dual mSATA slots, as well as two internal SATA ports, the card offers an effective hardware RAID solution, with native RAID (0, 1) support.

The PCIe SATA controller also offers Port Multiplier (PM) support, so you can connect multiple SATA drives to just one port, for a total of 7 drives (up to 4 drives through PM on one port, plus a single drive to the other SATA port and two mSATA slots).

For added versatility, the controller card is equipped with a standard profile bracket and includes a low-profile/half-height bracket for installation in small form-factor computers.

Rated 5 out of 5 by from Lots of tricks to use 1st installed and system(s) just came up with black screen: no system BIOS, errors or "Control-M" messages. BIOS MUST be set to PCIe Gen2 and legacy boot to get anywhere and then I still did not get a card BIOS setup message (Control-M for card setup). Accidentally accessed by hitting the keys during startup.

Rated 5 out of 5 by from PEXMSATA3422 is an asset.

Rated 5 out of 5 by from Excellent hyperduo and RAID controller I've bought two of these for storage of video. I run them both as RAID1/hyperduo and get very quick file reads and writes. One runs in a Supermicro X10slq and one in an ASUS Q270. Getting into the rom setup is easy in the supermicro, but a pain on the ASUS (as mentioned in another post). I definitely think it is worth getting to use as a large quick raid especially if you don't have the sata slots.

Rated 5 out of 5 by from Nice add-in card for extra fast storage I've had one of these installed in my PC for over three years and it had s been great. I use WD red Sata drives which are slow but reliable, but pairing them with 256GB mSATA SSDs in a hyperduo mode gives them quasi-SSD speed.
