This year both Seagate Technology and Western Digital Corp. introduced hard disk drives with breakthrough capacities designed for near line storage applications. Since those hard drives are based on enterprise-class platforms, they are too expensive not only for consumers, but even for cold-storage applications. This week Seagate quietly added the Archive family of hard drives into its lineup, which will combine maximum capacity with affordable price-points.
Seagate Archive hard disk drives are based on 1.33TB shingled magnetic recording platters and are available in 5TB, 6TB and 8TB capacities. The drives feature 5900 revolutions per minute spindle speed, 128MB cache and Serial ATA-6Gb/s interface. The manufacturer declares up to 150MB/s average data rate and up to 190MB/s maximum sustained data rate. Typical power consumption in operating mode of 5TB HDDs is 5.5W, whereas 6TB and 8TB hard drives consume up to 7.5W.
Seagate’s Archive series of hard disk drives are designed for cold storage applications and feature “the best” cost per terabyte available today as well as moderate power consumption, according to the company. Since it is hard and expensive to store petabytes of information that is not accessed, used or updated, many datacentres these days build cost-optimized cold data storage infrastructure. Cold data storage solutions do not use RAID or any other sophisticated technologies utilised for “hot” data storage devices. The main goals of cold data storage applications is to store maximum amount of data per square meter of a datacentre while consuming the lowest amount of energy. Seagate’s Archive and WD’s Ae HDDs are designed to do just that: they do not offer truly high performance and are not tailored for maximum reliability. However, they can hold up to 8TB of data while consuming up to 7.5W.
“Public and private data centers are grappling with efficiently storing massive amounts of unstructured digital content. Seagate’s new 8TB HDD provides IT managers with a new option for improving storage density in the data center, thus helping them to tackle one of the largest and fastest growing data categories within enterprise storage economically,” said John Rydning, IDC’s research vice president for hard disk drives.
At present official recommended prices of the Seagate Archive family are unknown, but Amazon.com offers 5TB, 6TB and 8TB models for $228, $243 and $267, respectively. Note that the prices are for 20-unit packages to be delivered early next year, therefore, actual retail prices are going to be higher. Nonetheless, even at $300 Seagate’s 8TB HDD should be considerably more affordable than HGST’s UltraStar He6 (helium-filled sealed hard disk drive), which costs starting from $722.

KitGuru Says: It will be very interesting to see whether emergence of Seagate’s Archive high-capacity hard drive have any effect on prices of other high-capacity drives. Keeping in mind that HGST’s 8TB drive costs almost two times more than a rival of the same capacity designed for a similar market segment, Western Digital should clearly reconsider the price of the UltraStar He8 HDD…
Perfect for home NAS for light access to practically never accessed data.
Just buy 2 drives and back one up onto the other and your are done. No need for expensive RAID5, no need to have all data written to both drive simultaneously in RAID1 mirror either, nothing mission critical in a home NAS. Back up on the second drive once a day and only update the data that have changed and that’s it (no full backup, just mirror backup drive A to drive B and only update the changes). This way, the backup drive is practically never in use, it’s sleeping all the time. Do that for 3 years and then reverse the main and back up drive to spread the wear and tear evenly and your good to go for another 3 years.
This also avoid scenarios where you loose the entire RAID array or must rebuild a 24TB array of 3X8TB drives because 1 drive died, rebuild that would take for freakin ever (weeks, not days). No need for an expensive RAID card, no need to buy a backup RAID card becasue the array would be useless if the RAID card dies and the product is discontinued/not available anymore. You can also migrate this solution anywhere, anytime, as long as you have SATA ports.
4X8TB with 16GB of data and 16GB backup would be relatively cheap and more reliable than RAID5 and RAID1. As soon as the newer 2TB TB per plater are here I’ll get 4 X 4 platters 8TB drives. 6 platters is 2 too many for my taste. Can’t wait to see the actual reliability of those drives! Even at a lowly 300 000 hours MTBF, and usually MTBF are only good for 50% of the projected reliability, that’s still 17 years of service on average.
Bring the price to below 250$ for a 4 platters 8TB drive, and I’m all in.
Still thinking about WD Purple Surveillance Storage, yes I know there for Surveillance but with such features how can you not wanna have them for your media needs. All I need are two and I’m happy for along time, that is until I start ripping Blu-ray.
