WD NAS Family
WD has an expansive NAS family of HDD's to suit every need. In today's product evaluation, we compare the performance of the Red, Se and Re.
The primary purpose of the Red HDDs is to serve the NAS and RAID user base. This is accomplished through a mixture of features that are tailored for small-scale NAS usage. The recommended limit of 1-5 drives per NAS or RAID group limits the Red's to home and SOHO (Small Office/Home Office) usage models. The Red HDD's include IntelliPower, NASware 2.0, and 3D Active Balance to suit them for NAS usage. Typical desktop HDD's do not include these features. The Red HDDs have a three-year warranty period.
For larger deployments of 6-12 hard drives, the WD Se series provides optimal storage for NAS and scale-out architectures. The 7,2000 RPM Se is designed for Small-Medium Business (SMB) and large-scale enterprise use with a moderate workload requirement. The Se drives spin at 7,200 RPM and feature enterprise-specific characteristics such as StableTrac, RAFF, TLER and enterprise-class firmware. The Se series also has a longer warranty period of five years.
The Re series spins at 7,2000 RPM and offers many of the same features as the Se model, but is designed for heavier workloads. The Re series is intended for entry to high-end datacenter NAS use in rack-mount environments with large numbers of HDDs. These drives feature many of the same features of the Se, but also come in with the option of SAS for high-availability and SATA 3GB/s.
The final offering from WD comes in the form of the 10,000 RPM XE, which is designed for high performance storage. These drives are only available with a SAS connection, and feature a five-year warranty period.
