Hitachi Deskstar 7K3000 3TB 7200 RPM

[onethreehill]

The Deskstar™ 7K3000 is Hitachi’s first hard drive to deliver an enormous three terabytes of storage capacity and 7200 RPM performance in a standard 3.5-inch form factor. The 7K3000 is also the first Hitachi hard drive with a 6Gb/s SATA interface, which along with its 64MB cache buffer delivers a big boost to performance over the previous generation product. The Deskstar 7K3000 is designed to allow manufacturers to leverage the benefits of the latest components and operating systems to deliver high-performance, high-capacity, power-efficient systems. Manufacturers planning to use the highest capacity 3TB drive in systems should consult the Hitachi High Capacity Technology Brief. Deskstar 7K3000 is also available in 2TB and 1.5TB models that accommodate existing systems, as well as new designs.

wow, impressed with the 7200 rpm.

now the question on everyone's mind:
how many platters?

[LyP0]

seeing as samsung F4 already rocks with 5400 rpm this should be awsome. i'm hoping on a 3 platter... no realistic though. more like 4 or 5 disk array.
If this is a 3 or 4 platter i'm betting we'll see an even bigger disk before H2 2011.

[zanzabar]

i would bet 5 600GB platters

[bamtan2]

I agree

[ripken204]

6Gb/s and 7200rpm... why?
7200rpm is fine to have, not really necessary since these will normally be used as storage drives.
but why the hell 6Gb/s? marketing gimmick?

it makes it more compatible since u need all devices to be the same sata mode and there is no real increase in cost, i would not pay extra for a sataIII drive but there will be the need to transition so why not.

if the plan is to switch all drives to sataIII then that is reason enough.
i would expect all future drives to be sataIII then, if not, then marketing gimmicks.

What is this line?

Media transfer rate (Mbits/sec, max) - 1656
Interface transfer rate (MB/sec, max) - 600

That would equate to 207MB/s, which would be extremely quick. Enough so that I think I'm going to be on record as being suspicious until I see it proven. But if they can pull it off, well, that would be pretty sweet. I guess we'll have to see whether they're actually talking about the speed one can hope for from the drive or whether they're referring to a totally pointless potential internal transfer rate that won't reflect on the actual speed of the drive as a whole (eg. exactly like they are in quoted line #2).

Also, price? Availability date? Hopefully they can get this out in a reasonable time and at a reasonable price... the slow production of 2+TB drives and silly prices for them needs to stop.

[ripken204]

probably talking about burst speed, keep in mind that is max, not average.

[Serra]

Platter drives don't really burst, except from cache. It could be that's what they're talking about, others have made that claim before. If they're talking about actual disk speeds it would definitely be start-of-disk speeds and not end-of-disk.

A current WD 2TB drive is something like 160MB/s to start, so it's actually conceivable that it is the speed of the drive... but again, we'll see.

3TB of info on one disk scares me... theres never an amount of data thats acceptable to lose... but 3TB in one go if there is a catastrophic PSU failure or platter failure?

same here.. I'm sticking with 1TB for a while still - they can only get cheaper too!

if they do ~207MB/s .. thats insane.. I cant wait to see how much MB/s this platter denisty gets in a 15Krpm SAS drive

Nevertheless, higher density platters with inevitably proliferate into smaller drives, making them cheaper, faster, and possibly more reliable

[turbox997]

If I was to guess, these probably use 750GB platters since most companies have recently announced that as the current technology.

I'm also concerned about reliability, I haven't done any scientific research or statistical analysis, but to me it seems like hdd's just don't last as long as they used compared to lower disc densities, perhaps PMR technology is reaching it's limits in data handling as it becomes more and more dense.

[RejZoR]

I never liked Hitachi for some reason. Western Digital is my best bet. Though i'm hearing good things about latest Hitachi drives...

I have the 7200RPM 2TB version. Can't say I'm disappointed at all. It runs a little warm, but only a few degrees higher. If I was in the market, I'd buy a 3TB hitachi drive without question.

As for everyone scared of losing data, buy a 2nd drive to back up. That's what I do!

[Buckeye]

This is true and a large amount of data to have on one disk. But your statement is ture for any disk size and doesn't matter if it's a big drive or smaller ones.

I think we all have had drives go out at one point in time where we lost data. But you learn to make backups so this is not really an issue. If you rely on only 1 3TB drive for storage then at some point you might risk losing it all.

Get a second 3TB drive and use that one for backups. Get backup software such as Arconis and incase you need to recover data programs like DiskDoctor can recover data very easy. Build a WHS out of spare computer parts to store large amounts of data on or keep backups.

Learn these things and losing a drive is not that painful.

I'm running CrystalDiskInfo program that's monitoring vital HDD signs. As soon as one parameter goes beyond threshold, it will warn me. So the chances of losing something is very small (though not impossible). But i trust this program because it did warned me correctly on a going dead Samsung which was already causing BSOD's, but i couldn't figure out it was HDD that was causing them...

translation: "what backup?"

[crackhead2k]

Owned a 500 GB drive, It only died because I was stacking hard drives >.<" my bad.. It was running pretty hot too. I think HDs are pretty reliable if actively cooled by a quiet low rpm fan. Seagate LPs are pretty good for 89$ when I last bought them from NCIX. save spots for Sata ports/case bays instead of buying another board or controller...

>9000

Higher RPM drives use different, less dense, media unfortunately.

[uOpt]

That why you put your old array of 2 TB disks into the basement and mirror into a snapshotted backup array

[tiro_uspsss]

they are behind, but not *that far behind
current gen cheetahs do the predicted ~207MB/s that these 3TB do.. so another bump up with density..mmm..I'm just guessing, maybe ~250MB/s
