### ⭐⭐⭐⭐⭐ Excellent performance but loud
*by A***R on January 11, 2026*

This is a factory-recertified drive. I use it for cold storage (MAME, Atari-through-PS3/Wii ROMs) and have used it for music and movie backups in the past. It's a top performer as HDDs go, with sequentials, both read and write, around 230MB/s. It's been going strong for over a year. The one thing that may give users pause is that it is *not* a quiet drive, even as HDDs go, making a loud grinding or farting sound when the heads cycle because the actuator-arm seeking in enterprise drives is optimized for performance in loud data centers, which is normal for an Exos. In short, if you're a silence freak this isn't the drive for you. Numbers: CrystalDiskMark (MB/s) 71% full at 31C Seq1m / q8t1: 234.61 / 230.19 Seq1m / q1t1: 234.64 / 230.80 Rnd4k/ q32t1: 2.99 / 8.55 Rnd4k / q1t1: 0.92 / 15.66 Excellent benchmarks. Temps are well under control for an enterprise drive at consumer workloads. Owned: about a year with no issue.
