Fantastic way to get your hands on 2 x WD 8TB Red drives cheaply.

The WD enclosure is user serviceable so they expect and allow you to remove the drive from this unit unlike the single MyBook 8TB which requires you to break the enclosure.

You can of course use this as intended as a very large encrypted 16Tb USB 3.0 drive. Or 8TB using RAID 1 (Mirrored).

On the WD Store Front Page about midway down is a box on the left that says "Sign Up for WD Specials". If you enter your email address and click "Sign Me Up" you get an email sent to you instantly with a unique 10% off code.

Despite WD making the drives they seem to be out of stock for long periods of time with this drive just coming back into stock this morning after a long period away.

Unique 10% Code emailed to you also stacks with WDSTORECPN giving a fantastic prince of £377 for 2 x 8TB Reds

I could do with one of these for my Xbox. Already filled 4TB lol.

Decent price for what it is

I can't bear the thought of losing 16TB (or 2 x 8TB) of data due to hard-drive failure.
That would be suicide inducing.

that backblaze report got torn to shreads. I would suggest only about 30% of what's in the report is true/accurate

Wonder how long the defrag would take with a full drive used?
Other things to think about, creating partitions and which windows versions would recognise that size of drive.
I remember the days of people struggling with 200gb hard drives on windows xp as 120gb was the max recognised.A service pack fixed the issue i think.

It's actually more likely than you think. Power cuts, enclosure malfunction, damage etc.

Having said that, you should be keeping separate back ups for critical data anyway. So drive failure should be an inconvenience and nothing else.

Anyone with 16Tb of data and no backups deserves to lose the data......as is always the case when buying storage you should factor in the cost of more storage to backup the storage you are buying....

and remember with RAID you still have no backup, RAID can give increased availability via hardware redundancy but is never a backup solution.

You're missing the point then. If you lose 8TB the other 8TB has it backed up.

You're a liability to the internet Sir.

And if the failure is down to an issue with the array controller you've lost both drives and all of your data....

Most of the "Raid" implemantions in low end nas drives is nothing other than Linux MD raid, I'd be more worried about the drives being fried by a surge or dieing around the same time (which can happen)

Indeed...in my day job I look after racks and racks full of storage, disks of a similar age have a nasty habit of failing close together :-(

It is always out of stock from WD Store.

This morning it was back in stock only for a very short period before it runs out of stock again.


If you need it, should act quickly when it is back in stock. The buying decision should be made before hand. There is literally no time for discussion when it is back in stock.

I have 20% off + £10 off £100 order + free express delivery, I can have it for £334.

This morning I caught it in stock, but I was busy at work. So thought that I will buy it at lunch hour. When I check back in less than one hour, it became out of stock again.

This drive is selling around £500 on ebay, bear in mind RRP is £430.

There might be people who just bought few cheap and sell on ebay to make a profit when it is back in stock.

An onsite Raid back up is still a backup. STOP BEING PEDANTIC.

I'm not being pedantic at all...There is a HUGE difference between a backup and disks in a RAID config.

As i said before RAID gives you hardware redundancy in the event of one or more failed disks. In no way is it a 'Backup'

Amongst other things a backup will give you the ability to restore data deleted in error or to restore data from a completely failed Disk array....

RAID simply allows you to continue to access your data until you can replace a failed disk If one or more (depending on RAID level) disks are offline.

Pretty good price if you're after large drives. Certainly cheaper than buying the drives alone. Shame the stock is always out but you can always request notification from them.

It's quite likely! Think about it: you are running two drives from the same production charge, with exactly the same access pattern, heated to the same temp, switched on the same number of times.

These two drives are certainly MUCH MORE likely to fail on the same day than two random drives with uncorrelated use. It's like identical twins with the same diet dying of the same cancer - it's entirely possible.

By that same logic they're more likely not to fail. Statistically most hard drives don't fail. So if by that logic being part of the same batch links their reliability your odds of having two good drives from the same batch are higher than having 2 bad drives from the same batch. Where as having them from different batches doubles your chances of one of those batches being bad. See making up odds and statistics is flawed, we're just applying what feels like logic to a problem and making wild speculation.

Odds of having a dodgy drive are about 5% historically speaking. Yes some times certain batches and models seem to have a higher failure rate like certain 3tb Seagate drives from a few years back. But the data isn't in on these drives yet to make any assumptions with, so historically speaking across many models and brands less than a 5% failure rate is typical.

No sense using guess work, voodoo or trying to moneyball the odds. Just take wise precautions with your data back up strategy like not relying on RAID as a backup, having more than one backup and having at least one off site and you'll be fine and prepared for the inevitable day you lose a disk so that you don't make an emotional association with that failure and create some kind of superstition as to it's cause like certain brands, big drives or buying from the same batch being at fault.

Phew it's good you don't work in statistics.

Obviously there are certain brands and makes that have worse failure statistics - you call that superstition? When you buy a car do you also claim that all makes are the same and looking at breakdown statistics is voodoo?

I claim that harddrives sometimes fail because of wear and tear, because they were heavily used and are now at the end of their lifespan. That alone increases the odds that two drives used together fail together compared to two random drives failing together.

Likewise, if you were driving two cars exactly the same every day it'd be much more likely they break down together.

It's more likely than people think, also even if the 2nd drive does not fail on exactly the same day the addational stress on the drive caused by the rebuild onto a replacement drive (After all you have to read all of the data to re-mirror it) can also cause it to fail.

If the data is important then have a backup copy stored elsewhere, ideally offsite if possible.

If you don't want to pay out for one of these storage services or don't trust them with your data maybe consider putting a NAS as a relatives house as a lot of them now support syncing/backup over the internet, and some of them can even do a block level backup (Meaning if you change 1MB of data in a 10GB set of data, it only needs to transfer that 1MB change over the internet not the whole 10GB again)

It does largely depend on what the data is, if it's just something you downloaded you probably don't need to go to those lengths, but if it's photos you've taken whilst on holiday once lost you'll never get those back.

'addational stress' - accessing of the hard disc.

the reason they exist!
#31
Is it confirmed in writing anywhere that the hard drive warranties are still valid if used outside of the enclosure?

you can defo take these drvies out and put them in a nas once formatted?
