Western Digital to release 20TB HDD

Western Digital said at a media briefing in Johannesburg that it plans to release a 20TB mechanical hard drive.

The world's most-used storage brand already offers a 16TB HDD, but the company plans to increase the storage capacity of the cheaper HDD technology.
 
I have an 8-Bay NAS here at home, imagine what I could store with 8 X 20TB!!! Don't see me going for that much due to where do you back up so much data?

You still stuffed if the box goes down due to hardware and not drive failure!

Eh? Having hardware and not the drive fail are two different stress levels!

Just move your drive to a new device if your hardware fails... but if your drive fails? You're f*cked.

Drive failure is taken care of by RAID but hardware failure is an expensive exercise especially if the NAS box is legacy!
 
I have a NAS here and what do you think is the best type of RAID to use?
 
Backblaze will love their customers who buy 1 or more of these.

Having restored my own data a few times, plus from some bespoke NAS device and in-site massive amounts of data center data: Use RAID 1 or RAID 10 for critical stuff. Forget RAID 5. Use software RAID. Why?

Hardware RAID controller going bye-bye is a nightmare. "especially if the NAS box contoller is legacy and OEM". While it works, it's great. Till one day ... Yes, you can restore the data using special tools, but their mileages varies, is slow and it's pricey. The benefit is it relieves the CPU from disk management.

Many consumer NAS devices actually uses a little Linux kernel and software RAID. Software RAID is a breeze. Depending on what you use, you simply import the data (I :love: CloneZilla). However simply loading a PC with enough disk connectivity, with Lunix allows you to gain access to your precious data. I personally use a microserver with 4 disks in RAID 10 config, one large disk for backups. The actual server has been taken out by lightning a few times, the same data disks have just moved about. RAID 1/10 is not CPU intensive, unlike software RAID5 (stay away). This strategy has not only severed me well, but also clients of mine.
