## Overview

The StarTech.com PEXSAT34RH is a high-performance 4-port PCIe 2.0 SATA III controller card that adds four 6Gbps SATA connections to your desktop or server. Featuring Marvell hardware RAID support (0,1,1+0) and exclusive HyperDuo SSD auto-tiering technology, it intelligently balances speed and capacity by moving frequently accessed data to SSDs. Compatible across Windows, Mac, and Linux platforms, it supports Port Multiplier for up to 7 drives and comes with flexible installation brackets and management software, making it an ideal upgrade for professionals seeking reliable, high-speed storage expansion.

## Description

The PEXSAT34RH 4-Port PCI Express 2.0 SATA Controller Card with HyperDuo adds 4 AHCI SATA III ports to a computer through a PCIe slot (x2), delivering multiple internal 6Gbps connections for high-performance hard drives and Solid State Drives (SSDs). 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.) The PCIe SATA controller card supports Port Multiplier (PM), enabling multiple SATA drives to be connected to one port over a single cable, for a total of 7 drives (Up to 4 drives through PM on one port, and a single drive to the remaining 3 ports). Plus, the SATA controller card offers an effective hardware RAID solution, with native RAID (0, 1, 1+0) support.

Review: Great Product For Upgrading Your Computer - I purchased this controller along with a pair of 3 TB WD Hard Drives to upgrade the built in RAID Controller on my 4 year old MSI Mother Board. I had intended to use it to replace the built in controller but discovered that the BIOS on my mother board would not support booting from hard drives larger than 2 TB. Drives larger than 2 TB under Windows 7 require a BIOS that supports UEFI in order to take full advantage of the drive's capacity. So instead, I am booting from my original RAID controller and my original drives and using the StarTech controller and the new 3 TB drives for additional high speed storage in a RAID 0 configuration. The controller was recognized by Windows 7 and worked fine with the standard Windows 7 Drivers. I was pleased that the StarTech was compatible with the build in RAID controller. I had tried another controller but found that it wasn't compatible with the built in controller. The only problem that I encountered was with the driver that I downloaded from the StarTech site which I installed to "upgrade" the Windows driver. When I tried to run Picasa, after installing the StarTech dirver, Windows crashed. Very strange! I went back to the Windows driver which solved the problem. I highly recommend the StarTech controller. It is compatible with Windows 7 and my MSI Motherboard and has excellent performance.
Review: Hardware RAID works Linux - No fuss Linux RAID. Forget MDADM and MB driver software RAID junk. Install disks, install this StarTech.com 4 Port PCI Express RAID Controller, on boot setup controller config and one-and-done done. Using Ubuntu 22.04 and the OS recognized RAID drive no problem.

### ⭐⭐⭐ Will not support HyperDuo SSD from a Raid 1 Mirror Logical Volume.
*by R***N on January 19, 2018*

It will not support HyperDuo from a Raid 1 Volume, only 1:1 with a physical drive. This is not a limitation in the card itself. I think it's just the way that hyperDuo tech works. Works OK Running MSI Z270 on Win10 x64 i7 using WD Gold 1TB Sata3 with a Samsung PRO SSD. Very Fast. Just wish there was a way to cache a Raid 1 mirror volume on the SSD using hyperDuo. That would satisfy both requirements (speed of SSD, but benefits of RAID 1 mirror).
