Seagate Launches 1 TB and 2 TB Enterprise Capacity 3.5-inch HDDsby Anton Shilov on January 19, 2017 9:30 AM EST

Seagate has quietly added two enterprise-grade HDDs to its Enterprise Capacity lineup of hard drives. While the 'Enterprise' name has recently implied high-density products, the new 3.5” drives only store one or two terabytes of data and are aimed at businesses seeking for high reliability, 512 bytes sector size, but not a lot of storage space.
In the recent years, we observed two main trends on the market of HDDs: the number of drives sold has been decreasing because of strong competition from SSDs, but their average capacities have been increasing because of new technologies (e.g., helium, SMR, the evolution of PMR, etc.). Enterprises and operators of cloud data-centers are the primary consumers of high-capacity hard drives because such drives help them to reduce their footprint and optimize power consumption. Since such HDDs are used in multi-drive RAID environments and are subject to heat and vibrations, they are based on special platforms that ensure their long-term reliability (by using a motor attached to both top and bottom covers, dual-plane balance control, improved heads, special firmware and so on). Because such drives offer higher capacity, they are harder to make and test. Also, on top of a longer typically-business style warranty, they naturally cost more than desktop-class HDDs. Meanwhile, due to overall benefits they bring, cloud service providers and enterprises are willing to pay a premium for such HDDs. As it appears, there are also customers who need hard drives with improved reliability and performance, but who are not interested in very high capacities or the latest technologies.
The new Seagate Enterprise Capacity 3.5 HDDs with 1 and 2 TB capacities are based on the latest PMR platters and feature a native 512-byte block size, which is a requirement of some legacy applications. The HDDs have a 7200 RPM spindle speed, 128 MB cache and a SATA 6 Gbps interface. When it comes to performance, Seagate declares 194 MB/s max sustainable transfer rate, 4.16 ms average latency and up to 7 W power consumption. The 1 and 2 TB versions of the Enterprise Capacity 3.5 HDDs are rated for 24/7 operation, up to 550 TB/year TBW and offer all the enterprise-grade features that the higher capacity models, including on-the-fly error-correction algorithms, PowerChoice technology (enables data-center managers to lower power consumption of HDDs during idle time), RAID rebuild feature and so on.

Seagate did not announce exact pricing of its Enterprise Capacity 3.5 HDDs with 1 and 2 TB capacities. It is logical to expect such drives to cost less than higher capacity models, but do not expect them to cost like desktop HDDs because we are talking about models with enterprise features, which are physically different to other hard drives. Seagate targets very specific SMB and enterprise customers with its entry-level Enterprise Capacity 3.5, so, pricing per-GB will not be a bargain. Meanwhile, the HDDs are covered with Seagate’s five-year warranty and have MTBF rating of two million hours.

MamiyaOtaru - Thursday, January 19, 2017 - linkI'm down with single platter. The one drive that's failed in my machine in the last 5 years has been an SSD
Lolimaster - Thursday, January 19, 2017 - linkAnd I tried to convince myself seagate stealthy released the 1st 10-20TB HARM HDD's and anandtech had a typical typo... oh well...
wavetrex - Thursday, January 19, 2017 - linkThey are probably single and double platter.
Less disks = Lower noise = Lighter more resilient motor = Longer life.
alpha754293 - Friday, January 20, 2017 - linkI don't really know why Seagate would even bother. I mean HGST (which is a WD brand now) has 12 TB enterprise drives. So....I wonder what Seagate is doing and/or what they're planning/where they're going with this...
stevenrix - Sunday, January 22, 2017 - linkHopefully the life expectancy of those drives won't be like 3 months.
BigDDesign - Wednesday, January 25, 2017 - linkI just bought 2 WD Gold 2TB. I would rather have 2 than 1 4TB. The thought of losing 4TB all at once is scary and I can double up and more having a bunch of drives. Hard drives still have their place. Like the other lad said, they are recoverable. SSD sometimes brick. I remember when SSDs first came out. Only Intel was deemed reliable for business. Anywho, I'm hoping my new WD Golds are nice. Haven't set them up yet. I'm going to replace a 5 year old 2TB drive on my workstation, just for safety. Seems like a small price to pay and could see some performance increase. Dunno. I'm using Intel RST with a 64GB SSD for cache.
