If you are going to use a RAID array, it is a huge time and headache saver to use EC HDDs. I would have gone WD again, but only Seagate offers EC 2TB HDDs with SATA 6.0GB/s, so I went with a pair of these. Overall Review: I was using a pair of WD EC 500GB SATA 3.0Gb/s HDDs for years in a RAID 1 that I was very happy with. The faster system response times are often needed for RAID arrays so that no HDD falls out of the array. 147 MB/s sustained data transfer rate, compared to 138 MB/s of the Barracuda XT.Ĭons: There is a significant price premium for enterprise class HDDs like these over comparable non-enterprise class HDDs, because they are higher quality, longer lasting, and have faster system response times. 1,200,000 hours MTBF, compared to 750,000 hours MTBF of the Barracuda XT. Here is a little bit of a comparison between Seagate Constellation ES HDDs which are EC and Seagate Barracuda XT's HDDs which are not EC: It is rated a little quieter than the Seagate Barracuda XT. This HDD features a 64MB cache, and is fairly quiet. EC HDDs have a faster system response time that is often needed for RAID arrays, are typically higher quality, and designed to withstand being on 24/7. Only Seagate offers a 2TB EC HDD that is SATA 6.0Gb/s. It is an enterprise class (EC) HDD, sometimes referred to as RAID spec'd or server class.
