Hitachi started shipping 4TB hard drives on December 12th!

Finally, some good news on hard drives.

From what I hear, pricing will be high on these until middle of next year at which point it is expected that other manufacturers will begin shipping 4TB drives as well.

What is the over/under for bets on when we get 4TB hard drives from Kaleidescape?

I am going to fathom a guess that we will be looking at around September of 2012.

(I have no inside knowledge from Kaleidescape on the subject.)
 
I have no inside knowledge either. My guess is May 24, 2012 at 6:00 am EST.:D
 
I agree with the 3TB.......

Ouch...I hope not. I've been waiting on the 3TB drives so I can join the Kaleidescape party in style. I figure the 3TB drives are the sweet spot for blu-rays...a 3U fully loaded with 3TB's can handle two M700's of blu-rays (assuming a conservative 50GB per disk), with a little room to spare for DVDs. That's all of the K hardware that I can entertain for the next few decades. :)

Aye, famous last words there. Though you could get the pair-vaults with room using existing 2Ts, just not as much wiggle room (mine has been tracking fairly true on the just-over-2:1 ratio so far.)

Given this is only a consumer grade, soft-launched, and even the external isn't coming out until next month... I'd say we are looking 2013 based strictly on this announcement. Or December 22, 2012, since anything after that is all the same anyway, right? :D

Yep in the next 4 months we will see the 3TB drives

As of only a few weeks ago I was to understand they hadn't found a 3tb that made the grade, so I'd be surprised if something came to market so soon. I gave up waiting and ordered 2tb's.

That is probably true, although in true K form, we'll not know for sure until the actual release. I certainly would not wait around for larger disks, and for anyone that may have taken my earlier comment on a date as a statement of inside knowledge, forget it, I have no inside information about disk releases. I recently ordered a new 2TB as well.


Jim
 
Imagine 360Tb of useable storage in a 3U server!!!

This is pretty interesting also..... :)

Quote:
"A recent advance in platter data density promises up to 6TB per platter ? and you can squeeze five platters into a 3.5-inch drive. So that?s 30TB in a single drive"

Of course all things being relative it will take years for the HDD manufacturers to milk the hdd's one step at the time!

That would certainly help with BR storage! Unfortunately, I agree that there will likely be "baby steps' to get to that point.:(

There is a Moore's law on hard drives. I don't know what the exact expansion coefficient has been over the years but I think it is doubled about every 2 years.

I bought a 210MB Rodime 3.5" hard drive back in fall of 1989. That was the largest 3.5" drive in the world and the largest 5.25" hard drive was the 600MB Hammer. If we doubled every 24 months, we would be 2048 times the capacity, which would make 1.2TB the largest hard drive. Figuring going from 600MB to 4TB in 22 years, we have doubled 12.8 times or roughly once every 21 months over the last 22 years. I don't know how much deviation the industry has had from that rate - that would be interesting if somebody has a graph on it.

One of the reasons for the "baby steps" is because companies are not going to wait 21 months between new product launches and a 25% increase is going to be enough to warrant having a new item. I mean really, if you could choose a 2TB drive, or a 2.5TB drive, wouldn't you prefer the 2.5TB drive? 25% increases translate to roughly one doubling every 3 launches so you could have a 7-8 month new product cycle with that and keep up with Moore's Law. Also, realize the "baby steps" are not making the later items get pushed back but are not punishing people who need to buy something 18 months after the product is launched from buying something that is going to be 50% as good as what is coming out in 2 months.
 
All good points Mike.:)


Jim
 
Very good points. I remember adding a 10mb hard drive to my Apple II sometime around 1985 - it was called something like the "Cider" and it was physically the size of a large box and it sounded like a hair drier. I thought it was the coolest.

Will a new 3 tb or 4 tb drive work with a current 3U that has several 2 tb in it?

Yes, but keep in mind that you do not gain the additional storage value with the first two larger drives you put into a 3U. This is because of the Hot Spare requirement (the HS will always be as large as the largest drive in the system) and the KRAID (RAID will always be allocated to cover the largest drive in the system as well).

This means that once the larger drives are released, you will not see the "full" increased storage benefit until you install the 3rd drive (the first two being allocated as described above).

This is why I've reminded clients that holding out for larger drives when you only have two empty slots remaining in your 3U Server makes no sense because you do not gain any storage increase with the first two larger drives you install.


Jim
 
I still have six empty drives on my 3U. So four could be used for more storage. Can we expect a 3tb or 4tb drive in 2012? Thanks
