Nice, but...
These days I'm more interested in speed than capacity. Ultimately I'd rather have tiny SSDs than massive HDDs. It'd be nice to have something that's both big and fast but, you know: big, fast, cheap - choose two!
Seagate has spread its 14TB, 7,200rpm helium-filled disk drive tech across the PC, NAS, enterprise capacity and surveillance market sectors. A few years ago the idea of having a PC or workstation with a 14TB disk drive was fantasy. Dream no more: the 14TB helium-filled BarraCuda Pro (PDF) does cost about $580, though. The …
A real SCSI or SAS disc offers decent speed, reliability and longevity. Desktiop drives are so slow and unreliable they are likely to wear out before the user had a chance to fill them. In the year 2000 we had 15.000 RPM drives, so something spinning at 7200 RPM is consumer grade.
Well, first of all, even finding an SAS drive these days is like trying to buy a floppy drive, unless you happen to work in a data centre (which I don't), and I'd imagine that even they have a hard time finding any. Surely they're all using SSDs by now anyway, if for no better reason than to drastically reduce power consumption and thus costs. I dread to think of the power bill for a data centre filled with 15k drives in 2018.
Second, the few SAS drives I actually managed to find at retail all looked rather elderly, meaning they use older and much slower technology, and were ridiculously expensive. Did I mention that I can't afford expensive storage?
Third, NVMe M.2 utterly destroys SAS in both speed and price, and also unlike SAS is readily available.
As for tech wearing out... welcome to the 21st century. Nobody cares. People now regard tech like polystyrene cups. It has to be as near to free as possible, and just barely good enough to get the job done to the required specifications (i.e. fast), before chucking it in the bin and starting again with a new cup.
It's sad but true, and the rationale should be self-evident: in this era of austerity nobody can afford the luxury of genuinely high grade products, and getting things done quickly and cheaply is simply an unavoidable necessity.
Both are still good imho. 14GB HDD for video / video-game content and SSD as always for OS / Application startup etc.
On the budget retail side it hasn't been easy to find anything larger than 8TB Ext HDD / 256GB USB memory for years now...
Anyone know why?
Sadly you imagined wrongly: I work in the industry and everywhere you still see SAS drives. Yes, 15k is dying but there are still many many many 10k drives installed and running, with sizes like 600GB, 900GB, 1.2TB and 1.8TB. Yes, even in big data centers of major enterprises.
Same with SATA (NL-SAS) where it's mostly 2TB, 3TB, 4TB, 6TB and 8TB. Yes, 10TB and 12TB are also available but not yet sold too often.
Regarding power consumption: Replacing SAS-disks with approximately same sized SSDs will by the way not really help you much, for the usual 2U shelf with 24 disks the difference is only about 50-100W. The big factor is consolidating many racks of SAS- and SATA-shelves to only some rack units of SSD-shelves. You can easily consolidate the performance but now you can also consolidate the capacity.
With SSDs we're currently at 30.6TB per SSD. Not really affordable yet but 7.6TB SSDs are used often for this purpose.
And with the performance of SSDs you can activate all the juicy efficiency features, like inline-dedup and compression without noticeable latency hits which means even more usable capacity per rack unit.

I'm guessing the drive 'certified' for the larger NAS box costs more even if it's the same hardware barring some model number foolery.
The same goes for all manufacturers Red Blue Green branding. Maybe some insignigicant firmware changes but I doubt they are using better bearings, motors or heads etc.

Cookie cutter driver pops off the line, quick diagnostic test and the results point the blank drive to the correct labelling slot with the ones producing more vibration and/or heat heading for consumer land.
It's more or less the same with modern car engine mapping onto a software defined power band. How many 'different' 2.0 litre petrol motors will any manufacturers beancounters want to make?
I would love to get 28 TB of storage in my two bay NAS
Why?
At an average of 2GB per movie that's about 14,000 films, do you really need to watch 2 films a day for 20 years?
If music is your thing then assuming good quality FLACs at about 500MB per album that's 56,000 CDs worth or roughly 20 years listening for 8 hours a day every day.
Maybe you like reading, epubs average at about 250kb so about 100 million books, you may be a fast reader but not that fast. Mind you buy another one and you could store every book ever published (approx 130 million).
That's of course once you've collected and collated it all which would take a few years.
Alternatively I suppose it's big enough make a local mirror of PornHub.
Why?
My Photo and Video library are close to 7Tb[1]. That's Stills going back to 2003 and Video back to 2014. All shot by myself. A quick check showed that I've added 476Gb this year so far and it has been a quiet year.
I'm sure that there are other use cases.
Just thinking of using the storage for your copy of other persons work is IMHO rather shortsighted.
These things are perfect for archival use.
[1] Currently this is held on TWO 4-drive NAS systems in raid-5.

Which kind of makes my point - in 15 years you've generated almost (let's round up) 8TB so a 28 TB system assuming a slight annual growth in your output will last for another 25 to 30 years.
Far longer than the discs themselves will last and depending on your age, possibly longer than you will last.
Also as others have stated, 14TB in a system without redundancy is insane.
I also store various VMs
Ah, a valid use that may well eat a lot of space but how many VMs are needed?
My home server has 5 x 4Tb drives as R5. It stores all the familys files, kids school / uni work, films, music, downloads from early 2000 onwards (mainly old games that the kids can't get any more). I also store various VMs and backups of old server OSs and at the moment I have 1.51Tb of space left.
I don't need speed, but I need capacity. Saying that, a single 14Tb is a lot of data to lose if it fails.
you'd think 14Tb is excessive and yet... just all the photos and family (i.e. camera-made) videos here take up around 3 - 4 Tb. And then, there's this little-used term "backup"...
sure, some of it is excess (the other day I discovered a 12GB mp4 file on the camera sd card, only to find out it contains a (mandatory) 29 min of footage being all black, with my daughter making some off-stage comments every now and then (she must have forgotten to remove the lens cap).
And then, there are my tif files which take about about... 12 tb, currently, maybe more. Now, for that little-used term "backup".
And I haven't even started about my pron collection, never mind backup, and the backup's backup...
p.s. did I mention my multi-Tb collection of linux distros?
you'd think 14Tb is excessive and yet...
Of course there will be outliers who do need humongous amounts of disc space but they are very much the exception to the rule.
The vast majority of users will never need anywhere like that capacity and if they don't have multiple discs with redundancy then it's a disaster waiting to happen.
Really this kind of capacity is only of use to enterprise systems where they can afford to buy discs by the box full.
I'm afraid your assumption that "vast majority of users will never need anywhere like that capacity" is wrong, as people take picks (never mind that) and video (oh) at an increasing rate (and quality). Yes, arguably, this is just, well, rubbish (then never look at 99.99999% of it, ever in their lives), but this does not counter the fact of such videos growing fast.
Well, I suppose, as most of them have been sold (successfully) the idea of "cloud storage", they'll just happily record away, and the cloud (lol) storage providers will just as happily delete those older videos, as per their t&t, the same way our garbage truck collect the content of our bins and make it disappear (if only!)
I have 17TB in my home NAS, of which over 9TB is used.
The problem isn't films, it's TV series, especially when they're HD.
As an example, Halt And Catch Fire ( 4 series, all 1080p ) takes up 130G. That would obviously be considerably more if it was in 4k and if I had a lot more storage, it would be.

... or NAS drive has a re-silver lining.
It's all very well to dream about filling a great big N-bay NAS with 4TB drives. But I'd suggest people also consider time-to-resilver, and the increasing odds of additional drive failures during re-silver operations. Or maybe I'm just being unduly cynical and pessimistic...
I've heard many people saying "with drives that big you need at least RAID6 because a drive is bound to fail during rebuilding because it will take so long!", but I'm yet to here anyone who that's actually happened to.
If it's happened to anyone it's probably happened to an elReg reader, so share your stories folks.
In the meantime I'll be over here with a big stick, dealing with our biggest cause of data loss: Users.
Seen it happen at a company I used to support, drive failed in a RAID5 NAS, and before it could finish rebuilding another drive failed.
So it does happen, but at the same site I saw several of the same units rebuild happily after a failed drive was replaced, so it doesn't always happen
Years ago I managed a small server I had configured with RAID 5. One night the controller failed and all data was lost. Fortunately, one of two independent nightly backups had completed before the controller went titsup. I was able to restore the data to a temporary server before the company opened the following morning (it was an all-nighter to do it).
Is there no obvious reason why they don't make He blimps (silver mylar obviously) with SSD/hard drive storage onboard, as drive(s) would then be less vulnerable to corrosion etc as in an inert atmosphere already.
Gives a whole new meaning to "Cloud storage"...
Just navigate the "Navigator" to where its needed, and connect via microwave/etc link.
No need for docking, just use solar and onboard battery for position hold, drives full disk encrypted so if the thing gets lost nothing of value is ever onboard and besides every blimp communicates with every other blimp when in range for mirroring.
sadly, remain helium-high, over the last 2 years I have only recently noticed a SLIGHT drop of a 4TB external storage, down from about £120 to around £85 - 100. And then, some of us, think of back-up. So I don't expect larger capacities to actually become available at any reasonable prices at all. I mean, at a certain point, flash prices/capacity becomes attractive enough for most punters to make a switch, and then the regular drives become gone overnight, like a floppy. One hopes ;)
"Do these big drives have hardware assist? Multiple overwrites would get tiresome..."
There is still no evidence that a single overwrite with zeros would allow any data to be recovered. The unproven theory of reading data from gaps between tracks has been out there so long, it is an urban myth.
The "Secure Erase" leverages the on-controller encryption of drives that are compliant with the ATA6 command set (SATA and (IIRC) Ultra-ATA100/133 IDE drives), which is also why it's a 20 second drive wipe instead of a physical overwrite- the data is stored encrypted, and the secure erase command tells the drive controller to generate a new key which renders the bits on the platters into garbage, because you can't recover the encryption key.
The ATA controller has to support allowing the command (a great many don't!), and older drives don't understand the command anyway, so for wiping drives I usually go with my old standby of a 4 or 5 pass random fill with DBAN and a blanking pass at the end; (although even that's overkill; a single random pass and blanking ought to be fine for 95% of purposes. If you are paranoid, you should probably shred the drive anyway, which I generally prefer a trip to an underpopulated area with a nice backstop, and populate the drive with a series of dents and holes from rifles and other firearms. :) )
Well, 8TB, 10TB, 12TB and now 14TB HDDs are not meant to be backed up, and they are not appropriate for traditional RAID schemes due to incredibly long rebuild times, although some smarter RAID controllers have learned a few tricks about rebuilding very large HDDs. These HDDs are destined for scale-out, object storage clusters which protect data objects using replication (making multiple copies of data objects) or erasure coding (sharding data objects and calculating parity fragments). In object storage clusters, data protection focuses on the number of cluster nodes and not the HDDs in them. Replication and erasure coding is spread over cluster nodes. No one cares if HDDs here and there fail, which they inevitably will if you have enough of them. Immediately replacing failed HDDs is not a priority. Replicated and erasure coded data objects on failed HDDs will have their "missing" replicas and erasure coded shards/fragments re-created on other HDDs on other cluster nodes by the object storage software running on each cluster node.
Toshiba has received 10 potential offers for the company, eight of which would take the company private, while two would allow it to remain publicly listed, according to reports.
Toshiba shares are said to have risen as much as 6.5 percent following the news, with some estimates valuing the deals at up to $22 billion.
The Japanese conglomerate announced in April that it was considering proposals to take the company private following numerous scandals and pressure from investor groups.
Toshiba has appointed two directors from activist hedge funds to its board in a move that could tip the balance in favor of a sale that would take the company into private ownership.
Shareholders of the Japanese conglomerate voted their support for all 13 director nominations recommended by the company during the annual general meeting of shareholders held on June 28 in Tokyo.
This included two directors from hedge fund investment companies, a contentious move that led to the resignation of external director Mariko Watahiki, a former high court judge, who reportedly objected to their appointment on the grounds that it skewed the membership of the board towards activist investors.
Western Digital has confirmed the board is considering "strategic alternatives" for the storage supplier, including spinning out its flash and hard disk businesses.
This follows calls last month by activist investor Elliott Management, which has amassed a $1 billion investment in WD equating to a six percent share stake, for a "full separation" based on those product lines.
In a statement, CEO David Goeckeler said: "The board is aligned in the belief that maximizing value creation warrants a comprehensive assessment of strategic alternatives focused on structural options for the company's Flash and HDD businesses.
Disgraced tech giant Toshiba has revealed it has received ten buyout proposals, and devised a plan to grow its digital businesses.
"As of today, the Company has received eight initial proposals for privatization, as well as two initial proposals for a strategic capital and business alliance with the Company remaining listed from Potential Partners," the Japanese conglomerate stated in a canned statement [PDF] dated June 2.
Toshiba didn't say who submitted the buyout proposals, but Bain Capital is known to have expressed an interest. Reports have indicated CVC Capital Partners and KKR might be in the running too. It's worth noting that CVC has sought this opportunity before.
Ailing Japanese giant Toshiba has revealed it has 10 potential suitors for its possible sale.
A Friday announcement revealed that Toshiba's decision to consider a sale to a private buyer has progressed to the point at which discussions are under way with §0 parties who have expressed an interest in submitting a proposal to buy the company.
Those talks have become sufficiently serious that Toshiba has appointed two sets of advisors – from Mizuho Securities and JP Morgan Securities – to offer financial advice and assist the special committee Toshiba assembled to consider offers.
Updated Activist investor Elliott Management is pushing for Western Digital Corporation's board to break the business in two by splitting the hard disk drive and NAND flash divisions into separately traded entities.
In an open letter to the board [PDF], Elliott – which has over time invested roughly $1 billion in WDC, representing about a 6 percent stake – says it is almost six years since WD bought SanDisk for $19 billion, scooping up its NAND memory biz.
At the time, this purchase was "nothing less than transformative", the letter adds, propelling five-decade-old WDC beyond HDDs into one of the biggest players in flash. Synergies, a better strategic position, and enhanced financial profile were among the rationale for the deal, says Elliott.
One of Toshiba’s largest shareholders has called upon the company's board to solicit bids to acquire all or part of the ailing Japanese giant.
The shareholder in question is 3D Investment Partners, which owns 7.6 per cent of Toshiba. On Wednesday it spelled out its disappointment in an open letter that notes shareholders have now opposed four turnaround plans proposed by management.
The letter expresses 3D's displeasure as follows:
Toshiba has decided it will consider proposals to take the company private, and devise yet another strategy to improve its performance, suggesting alternative proposals for the company's future will be revealed – and perhaps decided - in late June.
The beleaguered Japanese giant yesterday announced [PDF] it has created a special committee to consider any offers for the company.
Membership of the committee is only open to Toshiba's independent directors – an important decision because investors have already rejected two plans cooked up by the company's management, and expressed displeasure at many management decisions.
Updated Singapore-based Effissimo Capital Management, the largest shareholder in troubled Japanese tech giant Toshiba, has signed a deal to sell its stake to American private investment firm Bain Capital – if Bain decides to launch a takeover bid.
As explained in a regulatory filing Effissimo submitted on Thursday, the deal does not bind the investment firm or Bain if a better offer, or rival buyer, comes along.
Effissimo vigorously opposed Toshiba's plan to split itself into two companies earlier this month. That plan and a previous strategy to split into three companies were Toshiba's attempts to put years of scandal and underperformance behind it.
Toshiba's shareholders have rejected both the company's plan to split into two companies and a proposal to look for a private buyer.
The company today staged an extraordinary general meeting (EGM) to consider both proposals. The plan to split the company into two listed entities was developed by management after a previous plan to split into three was not well-received by investors.
Both plans were a response to years of management and governance failures – plus serious financial and corruption scandals – that drew investor agitation for a turnaround plan.
