Hitachi Deskstar 7K1000 Terabyte Hard Drive

Introduction

Introduction 
 
Hitachi LOGOFor many years, hard disk drives were large, cumbersome devices, more suited to use in the protected environment of data centres or large offices than in a harsh industrial environment (due to their delicacy), or small office or home (due to their size and power consumption).

The capacity of hard drives has grown exponentially over time. With early personal computers, a drive with a 20 megabyte capacity was considered large. During the mid to late 1990s, when PCs were capable of storing not just text files and documents but pictures, music, and video, internal drives were made with 8 to 20 GB capacities. As of mid 2008, desktop hard disk drives typically have a capacity of 500 to 750 gigabytes, while the largest-capacity drives are 1.5 terabytes.
 
Today we have have the pleasure of testing one of the largest capacity HDD's available on the market - the Hitachi Deskstar™ 7K1000 1TB hard drive. Interestingly, Hitachi were the first to market with a 1TB HDD and the DeskStar 7K1000 is the direct result of Hitachi's dedication to pushing the technological envelope. Let's begin the review by taking a look at the Hitachi DeskStar 7K1000 1TB's specifications...

Hitachi has always been one of my favourite HDD manufacturers'. They are renowned for producing solid, quiet drives that provide more than acceptable read/write performance. The Hitachi DeskStar 7K1000, according to its specifications anyway, appears to continue the trend. Let's take a look at the Hitachi DeskStar 7K1000 in a little more detail over the page...

Looking for some seriously beefy storage that isn't a slouch when it comes to performance? Hitachi's DeskStar 7K1000 may have what you're looking for...

Great review m8.

What I draw exception to on harddrives these days, and not this one in particular, is that the mounting holes on the left and right side that astride the pcb mount still do-not protect the pcb from screws being used that are too long.

To the rear of the drives (the non pcb) there is an enclosed space where the screws can draw into and then hit if they`re too long.

As an example I mounted a 1TB WDC drive, to which the makeup is almost exactly the same as this drive according to the nice pics. In moving the drive from one cage to another I happened to use case-style screws and 1 of them happened to be millimeters longer than the others. As a result it was shorting something on the non visible side of the pcb.

On boot, the mobos I tried it on (whilst keeping it in the same cage) reported "disk not reset info!" or similar, taking it out of the cage completely it went through ok, on doing so I noticed the 1 screw was that much longer than the rest - hey a case-type screw is a case-type screw.

All it requires is an enclosed area like the rear two screw-holes have and it saves a bunch of trouble. It`s not like the harddrive people always enclose screws for u, so u often delve into the "similar screws" box u have laying around.

Meh, the drives are great performers tho, can`t argue with that.

Thank you mate and I totally agree, it leaves next to no margin for error.

Fantastic Review PV!

Not sure who at the point in time needs 1000 odd gigs of storage but a good drive none the less.

Thanks mate for the feedback and I'm glad you enjoyed the review. Although many people probably wouldn't need 1TB of storage, it's certainly cheap enough to now

I bought 1TB of storage when I got my new rig just because it is that cheap. I maybe could fill up 500GB straight off if I was that way inclined to rip DVDs etc. On the other hand, I'm off to Uni and having near limitless amounts of disk space may be useful in the event I can't pop down to the nearby shops to buy extra HDs. (The joys of living in Manchester, so many cheap suppliers, so little time (so much rain))

I've about 5TB of data on hard drives atm - be it externals or internals.

Great review btw.
