Seagate officially unveiled its Exos X18 hard drives on Thursday, which have been shipping to some customers for some time. The new drives are designed for hyperscalers, data centers, and enterprise NAS systems that require maximum capacity, reliability, and 24/7 availability. The Seagate Exos X18 is the fifth generation of the 3,5-inch helium-filled hard drive family with a rotational speed of 7.200 rpm. Hard drives can store 16TB or 18TB of data using eight or nine platters. Hard drives rely on conventional magnetic recording to ensure predictable write performance. Aimed at multiple customers with different servers, the Exos X18 can use a SATA or SAS interface, as well as 512e or 4KN format. The SATA version has an average power consumption of 5.3W, while the SAS version consumes 5.8W. When it comes to performance, Seagate rates its 18TB Exos X hard drives for a sustained data rate of 270MB/s and also claims that the new drives offer higher random read/write I/O per second. (IOPS) compared to previous generations of hard drives. .
18 TB for Enterprise and Hyperscalers
Since hard drives in data centers operate in multi-bay racks, a highly vibrant environment, Seagate Exos hard drives come with a number of reliability features, including a dual connection engine and virtual reality sensors for ensure reliable performance. Stable and predictable performance. In terms of endurance, the manufacturer rates its Exos hard drives for up to 550TB / year of workload over a five-year period.

(Image credit: Seagate) 18TB capacity hard drives allow businesses to store up to 4320TB of data in a single standard rack (240 drives), 11,1% more than 16TB hard drives. Using extremely dense 4U servers with approximately 100 3,5-inch hard drives inside, they can now store up to 1800TB per enclosure or 18PB (petabytes per rack). Cloud data center owners are always willing to increase their capacities per watt per square foot, which is why they value high-capacity hard drives. The Seagate Exos X18 hard drive is available now at retailers and resellers for an MSRP of €561,75, which is slightly lower than the €599 price tag for the drive that was listed last month. At $32 per terabyte, the Exos X18 isn't the cheapest hard drive per TB, but its main selling point is its extreme capacity that maximizes storage capacity per rack, and therefore per data center.
