HDD-8261 Overview
The HDD-8261 PXI Express/cPCI Express Storage Module supports a software-based striped/ simple/spanned RAID array. The HDD-8261 is a three-slot wide hard drive storage device that holds up to four or six 2.5 in. solid-state or mechanical laptop hard drives. The module has a GEN2 x8 PXI Express high-bandwidth connector to the chassis backplane.
Note The only supported version of Microsoft Windows is Windows 7 (64-bit).
Using the HDD-8261 in any other version of Windows results in reduced performance and is not recommended.
Optimizing Streaming Performance

Understanding RAID ex88ay
The HDD-8261 2U in-chassis storage module expands NI high-speed streaming solutions by offering high in-chassis data streaming rates and storage capacities, using software RAID combined with either HDDs for capacity or SSDs for bandwidth. For maximum streaming bandwidth, use the HDD-8261 in the PXIe-1085 chassis with the PXIe-8880 controller.
The HDD-8261 offers up to 2 GB/s read and write speed for the SSD drive option and up to 250 MB/s read and write speed for 80% of the striped array (RAID 0) capacity across all four drives in the HDD drive option.

SSD/HDD Performance
The system configuration used for this benchmarking included a PXIe-8880 embedded controller running Windows 7 64-bit OS, with 24 GB system RAM, in PXIe-1085 chassis. For best throughput, configure a striped volume across all the drives of the HDD-8261 using disk management.

MB/s
Note The HDD-8261 HDD version performs best in a PXIe-1085 chassis with fans
set to Auto. With fans operating on High, performance degrades due to increased vibrations.
Hardware Installation
Caution To protect both yourself and the chassis from electrical hazards, leave the
chassis off until you finish installing the HDD-8261.
Note For important information about using the HDD-8261 with chassis fans on
high, go to ni.com/info and enter Info Code HDD8261Setup.
