<p style="box-sizing: border-box; margin: 13px 0px; padding: 0px; border: 0px; font-family: Arimo, sans-serif; font-size: 14px; line-height: 21px; vertical-align: baseline; color: rgb(68, 68, 68); -webkit-text-stroke-color: rgba(0, 0, 0, 0); -webkit-text-stroke-width: 1px; background-color: rgb(246, 246, 246);"><span style="color: rgb(0, 0, 0);"><span style="font-size: small;">The SMB / SOHO / consumer NAS market is expected to experience good growth over the next few years. With declining PC sales and increase in affordability of SSDs, hard drive vendors have scrambled to make up for the deficit and increase revenue by targeting the NAS market. Hard drive models specifically catering to 1-5 bay consumer NAS units have been introduced by both Western Digital and Seagate. Seagate took the lead in the capacity segment with the&nbsp;launch&nbsp;of the 4 TB NAS HDD in June 2013. Western Digital achieved parity with the launch of the second generation WD Red models&nbsp;yesterday.</span></span></p> <p style="box-sizing: border-box; margin: 13px 0px; padding: 0px; border: 0px; font-family: Arimo, sans-serif; font-size: 14px; line-height: 21px; vertical-align: baseline; color: rgb(68, 68, 68); -webkit-text-stroke-color: rgba(0, 0, 0, 0); -webkit-text-stroke-width: 1px; background-color: rgb(246, 246, 246);"><span style="color: rgb(0, 0, 0);"><span style="font-size: small;">The higher end SATA DAS/NAS storage segments have been served by 4 TB models for quite some time now. The WD Re (targeting applications where durability under heavy workloads is important) has been available in a 4 TB version since&nbsp;September 2012, while the WD Se (targeting applications where scalability and capacity are important) was introduced in&nbsp;May 2013.</span></span></p> <p style="box-sizing: border-box; margin: 13px 0px; padding: 0px; border: 0px; font-family: Arimo, sans-serif; font-size: 14px; line-height: 21px; vertical-align: baseline; color: rgb(68, 68, 68); -webkit-text-stroke-color: rgba(0, 0, 0, 0); -webkit-text-stroke-width: 1px; background-color: rgb(246, 246, 246);"><span style="color: rgb(0, 0, 0);"><span style="font-size: small;">The correct choice of hard drives for a NAS system is influenced by a number of factors. These include expected workloads, performance requirements and power consumption restrictions, amongst others. In this review, we will discuss some of these aspects while evaluating four different hard drives targeting the NAS market:</span></span></p> <ul style="box-sizing: border-box; margin: 10px 0px; padding: 10px; border: 1px solid rgb(238, 238, 238); font-family: Arimo, sans-serif; font-size: 14px; font-style: italic; line-height: 19px; vertical-align: baseline; list-style: square; background-image: none; background-attachment: scroll; background-color: rgb(249, 249, 249); color: rgb(68, 68, 68); width: 646px; -webkit-text-stroke-color: rgba(0, 0, 0, 0); -webkit-text-stroke-width: 1px; background-position: 0px 0px; background-repeat: repeat repeat;"> <li style="box-sizing: border-box; margin: 0px 0px 0px 30px; padding: 0px; border: 0px; font-family: inherit; font-size: inherit; font-style: inherit; font-variant: inherit; vertical-align: baseline;"><span style="color: rgb(0, 0, 0);"><span style="font-size: small;">Western Digital Red 4 TB [ WDC WD40EFRX-68WT0N0 ]</span></span></li> <li style="box-sizing: border-box; margin: 0px 0px 0px 30px; padding: 0px; border: 0px; font-family: inherit; font-size: inherit; font-style: inherit; font-variant: inherit; vertical-align: baseline;"><span style="color: rgb(0, 0, 0);"><span style="font-size: small;">Seagate 4 TB NAS HDD [ ST4000VN000-1H4168 ]</span></span></li> <li style="box-sizing: border-box; margin: 0px 0px 0px 30px; padding: 0px; border: 0px; font-family: inherit; font-size: inherit; font-style: inherit; font-variant: inherit; vertical-align: baseline;"><span style="color: rgb(0, 0, 0);"><span style="font-size: small;">Western Digital Se 4 TB [ WDC WD4000F9YZ-09N20L0 ]</span></span></li> <li style="box-sizing: border-box; margin: 0px 0px 0px 30px; padding: 0px; border: 0px; font-family: inherit; font-size: inherit; font-style: inherit; font-variant: inherit; vertical-align: baseline;"><span style="color: rgb(0, 0, 0);"><span style="font-size: small;">Western Digital Re 4 TB [ WDC WD4000FYYZ-01UL1B0 ]</span></span></li> </ul> <p style="box-sizing: border-box; margin: 13px 0px; padding: 0px; border: 0px; font-family: Arimo, sans-serif; font-size: 14px; line-height: 21px; vertical-align: baseline; color: rgb(68, 68, 68); -webkit-text-stroke-color: rgba(0, 0, 0, 0); -webkit-text-stroke-width: 1px; background-color: rgb(246, 246, 246);"><span style="color: rgb(0, 0, 0);"><span style="font-size: small;">While the WD Red and Seagate NAS HDD compete against each other in the same market segment (consumer / SOHO NAS units with 1-5 bays), the WD Re and WD Se are portrayed as complementary offerings for higher end NAS units. We will also try to determine how they differ in the course of this article.</span></span></p> <p style="box-sizing: border-box; margin: 13px 0px; padding: 0px; border: 0px; font-family: Arimo, sans-serif; font-size: 14px; line-height: 21px; vertical-align: baseline; color: rgb(68, 68, 68); -webkit-text-stroke-color: rgba(0, 0, 0, 0); -webkit-text-stroke-width: 1px; background-color: rgb(246, 246, 246);"><span style="color: rgb(0, 0, 0);"><span style="font-size: small;">Western Digital provided us with at least two drives each of the WD Red, WD Se and WD Re, but, Seagate came forward with only one disk. Readers of our initial WD Red 3 TB&nbsp;review&nbsp;would have found us evaluating the disks in multiple NAS units with multiple RAID configurations. Unfortunately, Seagate's sampling forced us to rethink our review strategy for these NAS drives. We will start off with a feature set comparison of the four drives followed by a look at the raw performance when connected directly to a SATA 6 Gbps port. A 2-bay Intel Atom-based NAS (LenovoEMC PX2-300D) with single-bay occupancy is then used to evaluate performance in a networked environment. Power consumption numbers and other factors are addressed in the final section with the networked configuration as a point of reference.</span></span></p> <p style="box-sizing: border-box; margin: 13px 0px; padding: 0px; border: 0px; font-family: Arimo, sans-serif; font-size: 14px; line-height: 21px; vertical-align: baseline; color: rgb(68, 68, 68); -webkit-text-stroke-color: rgba(0, 0, 0, 0); -webkit-text-stroke-width: 1px; background-color: rgb(246, 246, 246);"><span style="font-size: small;"><a href="http://www.anandtech.com/show/7258/battle-of-the-4-tb-nas-drives-wd-red-and-seagate-nas-hdd-faceoff" target="_blank">Read more...</a></span></p>
