## 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: Firmware version appeared to be important. But it's fixable by user. - I bought this controller 1st time in 2019, and after that I had some issues with it. I have a RAID1 array of 2 SATA drives 4 TB each. From the installation, it seemed to be working OK, but in a couple of weeks the array lost the integrity, so I had to reconfigure and sync it again to fix the problem. It continued working OK, but in a couple of weeks, the same issue happened again. After some research, I found that apparently, the firmware was not of the latest available version. So I found the latest version (2.3.0.1078 at that time) online together with an appropriate updating utility and performed the update. That required to run the update process in old DOS mode, but it's not a problem for an advanced user. After the firmware update, the controller works stable up to now, and doesn't cause any problems. Hopefully, this controller model is now proposed for sale having the last stable firmware version. I gave 4 stars to this product just because of this firmware issue, but I repeat it's fixable by user.

### ⭐⭐ Not working with Windows 10 Pro and new motherboard
*by S***S on May 25, 2020*

This board worked great with my old motherboard and i7 Intel chip. However, after I have installed a new motherboard with a new i9 chip and Windows 10 Pro, the board created a ghost disk that always generates a Virtual Disk Manager error "The request could not be performed because of an I/O device error". I have removed the device and reinstalled the driver from StarTech multiple times and the ghost disk continues to appear and the system continues to display an error. I will have to purchase a new SATA card.
