Batu69 Posted March 3, 2016 Share Posted March 3, 2016 WD today announced its 8TB HelioSeal consumer HDDs. To achieve such a large capacity the disks are filled with Helium in order to reduce internal resistance. The disks are available in both internal and external versions. The internal drives are the WD Red and WD Purple which rotate at 5400 RPM and have a cache of 128MB. The WD Purple drives are targeted for usage in surveillance systems while the WD Red drives are designed with NAS devices for home or small business in mind. The external drives are the My Book (for Mac) and My Cloud with both 8TB capacity. WD also has 16TB versions available which contain 2 drives. The high capacity is possible due to the usage of Helium. This gas has a lower density than air which has the benefit that platters and heads suffer from less friction. This in its turn reduces generation of heat which allows platters to be closer to each other. Because in Helium it takes less energy to rotate the platters, the Helium filled HDDs also consume less energy. To properly function the HDDs have to be air-tight. WD currently allows consumers to pre-order the drives. The WD Red and WD Purple are available at $345. The My Cloud and My Book can be pre-ordered at $299.

wacm1979 Posted March 3, 2016 Share Posted March 3, 2016 A lot of space but also a lot of eggs to put into once basket Link to comment Share on other sites More sharing options...
Pequi Posted March 3, 2016 Share Posted March 3, 2016 A reasonably priced basket though. Buy a couple and mirror them and your data should be safe for a long time. (No new technology has appeared that requires hundreds of GB for a single video/data file, I reckon THIS time round "a long time" will be just that. Back in the day I bought a 1GB HD and thought I was good for 3-4 years. I had to replace it less than a year later with a 4GB model.). ;) Link to comment Share on other sites More sharing options...
CODYQX4 Posted March 3, 2016 Share Posted March 3, 2016 I'd take a wait and see approach. This is using a new manufacturing technique (helium/whatever else), and new capacity. These first batches will never be as good as later batches where issues only found after they've been bought have been found. Link to comment Share on other sites More sharing options...

Seagate and WD are lagging behind with there 8TB ones http://arstechnica.com/information-technology/2015/12/hgst-releases-helium-filled-10tb-hard-drive-seagate-twiddles-shingled-fingers/ Link to comment Share on other sites More sharing options...
oliverjia Posted March 3, 2016 Share Posted March 3, 2016 what if the helium gets leaked out of the HDD metal casing. I doubt its reliability and durability will be as good as the 2-4TB ones. Link to comment Share on other sites More sharing options...

Im never going buy over a 1 tb because i dont like to store stuff on pcs were the O/S is installed its too risky to lose all the data . I have 5 tb external HHD that's not very old and some portable 1tb ones ive had for years and im happy with those. Link to comment Share on other sites More sharing options...

Im not going out my way to buy a bunch of space I will never use . Every Thing I have I want to keep plus I have many portable programs all stored on externals . I really dont install many programs on windows but what I use most the ones I dont use a lot I have as portables. I been on the internet since 2001 and never needed even 1TB internal even though most pcs comes with it for many years about 500gb is quite enough maybe i would use 38 gb of that Link to comment Share on other sites More sharing options...

CODYQX4 Posted March 5, 2016 Share Posted March 5, 2016 I have a 1TB SSD and a 4TB External HDD. Hopefully this tech is sorted out and much cheaper by the time I need more. Link to comment Share on other sites More sharing options...
