Score Breakdown
Product Overview
The Seagate Exos X24 and ExosM series of enterprise internal hard drives, available in capacities ranging from 16TB, 20TB, 24TB, 28TB, 30TB, up to 32TB, are engineered for demanding data storage environments such as hyperscale and cloud data centers. Owners frequently laud these 3.5-inch SATA 6.0 Gb/s drives for their impressive performance and robust build, making them a popular choice for storing vast amounts of critical data, from extensive photo and video archives to complex client projects. Many users report these drives performing flawlessly for months and even years, with some expressing a long-standing trust in Seagate's reliability, noting that they have "never had a Seagate drive fail" on them over decades, contrasting with experiences with other brands.Performance and Reliability
Owners consistently highlight the exceptional performance and transfer speeds of the Exos X24 series. Described as "fast," an "absolute beast," and delivering "very good performance," these drives meet high expectations for efficient data handling. Several users have noted no hiccups or slowdowns even under heavy load, with one owner confirming it "works well" in their server. The drives are also generally considered quiet for their class, with noise levels not significantly exceeding standard drives, and maintain excellent operating temperatures when housed in cases with adequate airflow. One owner specifically praised the "excellent temps as long as you have airflow in your case," indicating that proper cooling is key to optimal operation. Installation is typically straightforward, though one owner noted the need to connect a 24TB unit directly to the motherboard as their server bay maxed out at 16TB, indicating a need for appropriate system compatibility, particularly with larger capacities.Initial Quality Concerns
Despite the strong performance and reliability once operational, the Seagate Exos X24 series faces significant criticism regarding initial product quality. A notable number of owners reported receiving "dead on arrival" (DOA) units, experiencing clicking noises, or finding drives unformattable right out of the box. One buyer received a 24TB drive that showed only 21TB and produced clicking noises, suggesting a pre-shipment disk failure, leading to a return and replacement. Another user simply stated their "hard drive was dead and unable to be formatted." While some were able to successfully return and replace these faulty units with working ones, the occurrence of such issues points to a potential inconsistency in initial quality control that can cause frustration for new buyers.Value and Support
The most frequent and emphatic complaint among owners is the high cost per terabyte and the significant price volatility of these drives. Many buyers expressed frustration over prices doubling or increasing substantially shortly after purchase, making it difficult to acquire additional units for mirroring or expanding storage pools. Comments like "too expensive" and lamenting that "the price has doubled since" are common, indicating that while the drives are highly regarded for performance, their economic accessibility is a major drawback. Furthermore, there is limited positive feedback regarding warranty or support experiences. One owner mentioned installing a DOA drive just outside the return window, implying that recourse for defective units might be challenging or time-sensitive without prompt action, underscoring the importance of immediate testing upon receipt.Final Consensus
In conclusion, the Seagate Exos X24 and ExosM series offer powerful, high-capacity enterprise storage solutions that deliver on performance, speed, and long-term reliability for demanding users. Once past any initial quality control hurdles, these drives prove to be rock-solid workhorses, capable of handling extensive data loads for months or years without issue. However, prospective buyers should factor in the potential for receiving a defective unit and be prepared for a premium investment, as the cost per terabyte and price fluctuations are significant concerns for many owners. For those prioritizing raw capacity and proven performance in an enterprise environment, and who are willing to navigate potential initial quality issues and the higher price point, these drives are a strong contender.The Good
