Seagate's 8TB HD

[Data-Medics]

SMR scares me to death as a data recovery guy. Not only are these drives next to impossible to recover if the heads fail, but I just wonder how often data gets lost if the thing gets powered down during it's overlapping data re-write cycles. Makes me really doubt data integrity especially for database type applications.

I certainly wouldn't trust one. Espceially given Seagate's current reliability catastophy. I'm thinking the move by WD and HGST to fill the drives with helium, make the platters thinner and more of them might be the smart choice. Though I'm not looking forward to sounding like mickey mouse while working on them and having to refill with helium. LOL!

That and the helium will make all your movies and music sound funny.

I am curious, how do they fill these up with helium in the first place, I see no port where they can fill them.

I just assumed that there is a robot doing the assembly in a vacuum cage filled with helium and when the top is put on, it seals the helium in it. But then again, helium would leak out, unless the seal is leak proof.

8TB HDD's at $260? Lol...
So we'll see them at a far higher premium. At least it will push other drive prices down. I won't complain because the 1TB increases were really annoying. From 6TB to 8TB is very welcome.

If I ever actually see a drive hit retail at $260 for 8TB I'll pick one up.
Currently 6TB is still at aroudn $300 regularly.

 

[Red Squirrel]

That's not a bad price. I'd be tempted to do a 4 drive raid 5 with them or something. Use strictly for backups or other duplicated data.

 

[StinkyPinky]

wow, so that can hold about six to seven 4k resolution movies? "yay! I can finally start my 4k movie collection!" said nobody ever.

Interesting, I've never looked before. How big are 4K movies??

IIRC the uncompressed (i.e not pirated) 1080p movies aree about 20 gigs aren't they? Damn 4K must be enormous.

single sided single layer bluray is ~25GB, and a typical compressed 1080p is about that (blurays are compressed). 4k using the same compression technique would be 4x the size, i'd assume, so ~100GB

uncompressed movies are ginormous.

This.

Actual uncompressed video at 24 FPS is roughly 1 GB/minute.

Sheesh - Even with most of the 'extras' in my bluray's filtered out, the 1:1 rips take up so much space - not looking fwd to doing the same with 4k :s

 

[imagoon]

Damn, these are really old. I wasn't even born at the time.

But I'm talking about 3.5-inch form factor HDD's manufactured in the last 10 years or so :biggrin:

There hasn't been a year since the development of the 3.5" form factor that hasn't had drives with more than 1 platter. The first 3.5" drive, the Rodime RO352, was a 2 platter drive. Single platters were not that typical until fairly recently.

 

[StrangerGuy]

Really, who is THAT naive to believe blurays are uncompressed?

There is no point to fully uncompressed video anyway when there is loseless compression.

6-10 days @ 314 each.. enjoy !

BTW I dont know if my controller can even handle it.. its a hp smart array

I'm currently using 4tb drives with 16tb array..

It should be able to, unless they did something really dumb, and hardcode a max value it can support.
The 2TB limit was only because of a 32-bit limitation.
With 64bit, and you have a max of 9.4 ZB limit (9,400,000,000 TB).

I wouldn't mind upgrading to 8GB drives but not at that price.

I just picked up a 5TB Seagate external for $114 (TigerDirect @ $140 - $20 Visa coupon - $6 Discover 5% bonus) so I will probably wait until the prices for the 8TB drop to $250 or thereabouts. I'm willing to pay a slight premium but not $90.

 

[alzan]

You mean back in the 50's?

http://en.wikipedia.org/wiki/IBM_350

Heh. The drive in my avatar used 12 platters/22 recording surfaces @ ~13.6MB each for an abundant 300 MB per disk pack. Course that was '80's tech but still...

 

[harobikes333]

video on that page disappoints.

was hoping for another classic like https://www.youtube.com/watch?v=xb_PyKuI7II

Thanks for the chuckle Good stuff there.

 

[Elixer]

I am wondering, has anyone even thought about getting these beasts ?

http://www.bhphotovideo.com/bnh/cont...G&Q=&A=details

Looks like it will sell for $250

I am really curious on seeing reviews on this thing.

 

[Red Squirrel]

Can't seem to find it on sale anywhere in Canada. Was curious to see the actual retail price.

I don't know if I'd trust seagate though, but like 6-8 of these in raid 10 would be pretty awesome.

These'll get used for cold storage in data farms and not much else.

If you're writing performance critical DB applications, it'll still be to tier 1 SSD or 15k RAID-10, for 2015 anyway.

I am not sure about that, since they list 180TB lifetime writes to the HD.
It seems this new tech has some serious limitations on how it works.

I know it is geared toward long term storage, but still, that is a odd limit. Only about 22.5 times you can wipe/fill the HD up to remain under warranty.

What happens after that, do the shingles fall off, digitally speaking ?

 

[rumpleforeskin]

Purchased a pair of these to store my old media on, the speed during the initial sustained sequential write was better than I anticipated (110 MB/s) while transferring about 7 terabytes. Random writes after this where a lot slower as the drive shuffled data around rewriting the shingled tracks.

These drives seem ideal for their intended purpose, data archiving.

My main gripe with them was the mounting hole layout, almost all drives I have purchased in the last 10 years have used the standard bottom mount hole locations, this drive used the alternate hole layout which sadly did not match the HDD mount in my case.

Oh wow I missed this part. The limitations of SSDs, with the speed of a HDD. No thanks then. Though I guess they would be ok for backups. I could back my entire environment on one drive, and have multiple for different rotations. Not sure why they have a write limit though, it's still magnetic data. Unless there is flash in it too, maybe it has to update some kind of allocation table or something.

 

[fleshconsumed]

Yeah, the 180TB write limit is both odd and worrisome. Whatever happened to HAMR that WD was working on? For now I'm good with my 4TB drives, but I do wonder about my upgrade path. From what I understand, the biggest non shingled drive is only 6TB. Not much of an upgrade from 4TB if shingled technology turns out to be a dud.

You know its really old if it needs hydraulic fliud for the head actuator. They used to be used for the mass memory of the Fire Control systems on Tridents subs as late as the early nineties.
