When will the 5TB drives come out?

[titanmiller]

Are there any rumors about when 5TB drives will hit the market? We know that there are 1TB platters so I'm surprised that we have had to wait so long for five platter drives.

Like never.... or not within the next year or so.. HAMR is the newer recording method from early 2000s and seagate still can't make it profitable for them.. so.

The problem is that the technology has taken longer than expected to be commercialized. In 2002, Seagate thought it would be 2008 before HAMR could be commercialized. In 2004, Seagate pushed it out until 2010. On Monday, a Seagate spokesman said that HAMR was still several years away.

As long as there is money to be made on old crap, newer better stuff will never come out.

Why do we need to wait for HAMR? 1TB platters already exist, as do 5 platter drives.

why do you want 5tb when you can get 60tb

 

[jwilliams4200]

I'd rather have a 4-platter 4TB drive than a 5TB drive. But unfortunately, you cannot buy a 4-platter 4TB drive either. I don't know why.

I'm holding out for petabyte drives.

You'll be holding out for a long time trying to fill that up or back it up at 150 MB/sec...

 

[Hugo Drax]

Mercury Delay Line memory will be out by then.

Speaking of that...I've often wondered why I've never heard of an HDD with multiple heads and platters being able to read and write to multiple heads in parallel. For example, a typical 3 platter HDD has 6 read-write heads (2 heads per platter, since the platters use both sides). If the sectors were interleaved across the platters, in much the same way that RAID 0 interleaves the blocks across drives, it seems like you could achieve about 6 times the read or write speed of what could be achieved by a single head.

It seems so obvious that I feel like I must be missing something about why it is not done. By the way, it is obvious that it is NOT currently being done that way, since single-platter HDDs are no slower than multiple-platter HDDs.

Oh, give it a rest already! It gets tiring that every time there's a Hard Drive-related thread, you have to come in and make completely useless, off-topic comments about "how much Hard Drives suck" and "you'd never use one". Sorry, but no one cares, especially since you keep spamming the same comments every time you get a chance. It gets old and tiring.

At 150MB/s it only takes 33 mins to fill the entire drive with 5TB of data. Nice try.

5TB drives will probably be released first by Hitachi, and with 5400RPM spindle speeds. Hard Drive capacity development has taken a higher amount of time from around three years ago to now and probably in the future.

Except that he was responding to the person wishing for a Petabyte HDD, which would take 77 days at that rate.

And besides, your math is wrong for 5TB.

5e12/150e6/60/60 = 9.26 hours.

I would not trust a 5 platter 5tb drive. I'm already leery of the 4 platter drives. I think what we'll see instead is a push towards lower power 2.5" drives. Smaller, less heat, lower operating cost, fewer eggs in one basket. 2.5" drives cost about 40% more per GB, but the price disparity between 2.5" and 3.5" should begin to narrow. I'm ready to pay a premium just to get rid of the noise of 3.5 inchers.

 

[jwilliams4200]

I'm not. Also, for me, that premium would include extra HBA cards, since I'd have to buy double the number of 2.5" HDDs as 3.5" HDDs that I currently use to reach the same capacity as I have with 3.5" HDDs.

And I'm not sure if you are aware, there are currently 5 platter HDDs. Hitachi's 4TB HDD is 5 platters.

IIRC someone tried it, it was buggy. It is much more difficult to write firmware for such a beast a KISS comes into play.

There is also the issue of how expensive it is to add such capability.

Yeah, it is. Guess I got my divisions wrong.

But nearly no one is gonna need to transfer/store 5TB to the HDD right away, so it's inaccurate/non-representative of real world use.

And a 1PB HDD would be well over 400 or even 500MB/s due to platter density, so that 77 day number is meaningless.

Anytime you have to rebuild a standard RAID device, you have to read and write an entire drive as quickly as possible. That is certainly "real world use".

Who said anything about RAID? And most people looking for that capacity want media drives.

 

[jwilliams4200]

Who said anything about RAID?

I did. Are you having trouble reading as well as math?

 

[LOL_Wut_Axel]

I don't care that you did. No one wants 5400RPM desktop client drives for RAID, so you have a non-argument.

who is crazy enough to store 5TB of data without RAID?

 

[jwilliams4200]

Wrong. I have a snapshot RAID setup at home, and I use nothing but 5400rpm drives. When I lose a drive, I have to completely read the remaining drives, and completely write to the replacement drive (well, technically, not all of the drives get completely read if the lost drive is less than 4TB, since some are 2TB, 3TB, 4TB...but the replacement drive is completely written).

Also, most cloud storage businesses use 5400rpm drives in the RAIDs. They are going for large capacity, low power usage, not speed. There are a huge number of HDDs used in cloud storage, so that is a big chunk of the market. Real world, indeed.

 

[titanmiller]

I would not trust a 5 platter 5tb drive.

What makes 5 platter drives less reliable? Heat? I realize that there are more read heads, is the issue that it is more likely to have a head crash?

you are correct. But please try not being so rude and condescending.

Please try not to post so many incorrect statements, then I will not need to waste my time correcting you.
