Slimming Down Storage

Share

Sometimes a picture says it all. That’s exactly the case with
Hitachi
’s new Z-series family of hard drives, just announced today. The new 2.5-inch hard drives contain just a single platter and measure only 7mm in height. That’s just a tiny bit more than ¼ inch, and looking at the picture you can immediately envision the super-slim notebooks, netbooks, and tablets that will surely come to market in the near future.

The Z-series hard drives are available in capacities ranging from 160GB to 320GB, and in both 5400 RPM and 7200 RPM models depending on a manufacturer’s performance and power requirements. The drives are intended for use as direct replacements for today’s 2.5-inch, 9.5mm hard drives. In addition to notebooks, netbooks, and tablets, these new drives should also find homes in mobile storage devices, gaming consoles, DVRs, blade servers, and so on.

One wonders what the expected MTBF is....

What happened to solid state? Why aren't we focused on that? Isn't it the superior technology by far?

It's all about the mighty dollar...  Solid state drives at 160 gigs are still going for $400+  I'm guessing these babies will sell in the 70-120 range....

I imagine this would bridge the gap until SSDs become cheaper.

Hitachi -- the name for retro storage. When everyone was going to compact flash cards, Hitachi stuck with mechanical pc card mini hard drives.

Now the move is towards "solid state" non-mechanical flash drives and Hitachi again sticks with a horse-drawn carriage.

Although solid state drives are becoming more popular, they are at this time (2010) considerably more expensive than hard drives. Considering that a 160GB solid state drive is approx $430 while a 160GB hard drive (2.5") is about $60, it's easy to see there is still a viable market for slimmer, mechanical hard drives like the Hitachi Z series.

Maybe someone could use this for an iPad-looking PC. Please?

Why not just the iPad?   I know some PC IT types that really like it.

Something the manufacturers of solid state drives don't want to advertise is that these flash memory has much lower rewrite cycle (around 10k to 100k times), as well as slower writing compared to fast writing of hard disks that can write tens of millions or more times. That's why flash drives have special driver to rearrange the writing so the flash memories get evenly distributed (or worn). Reading is not an issue and of course much faster than hard disks. It is writing that is the killer. This coupled with high cost limits their wide appeal.

This is very disappointing information in this article seeing as though I am spending money now on off-site file storage for fear that my hard drives might burn out any day now.  As matter of fact it's down right asinine and insulting of Hitachi to re-introduce such old technology. Flash and solid state is most definitely the future and not mechanical hard drives.

It´s cheaper and make no noise. Perfect for storage files. Hitachi´s make great HDs, better than any other brand. Google-it. And i´ve 2 ssd´s here, and another 2 discs: Hitachi 320 G (great) and WD Caviar Green 1Tb (dont recomend to a friend).

Given that slimming down already slim products is bound to have diminished real effects with each step.

Will a drive which is 2.5 mm, (one-tenth of an inch), slimmer really set off a new range of more desirable devices. Personally I suspect not!

It's just Hitachi's USP of the moment, but there is no harm in trying to gain market share in this way, even if the effect is transient.
