The State of 100MB 7,200RPM Drives

The HTE721010G9AT00 is the "server" version of the 7k100, if you look at the specs closely, it probably has a lower temperature tolerance.

"The Travelstar E7K100 expands Hitachi’s secondgeneration 7200 RPM 2.5-inch hard drive series with further design enhancements for data intensive applications requiring round-the-clock operation. The E7K100 provides leading-edge capacity, performance, durability and power utilization on a proven platform for quality and reliability. With its 100 GB capacity, the E7K100 offers 66% more storage space as well as a 33% boost in sustained data rate over the record-setting Travelstar E7K60. Optimiza-tions in the femto-based actuator/suspension enable the E7K100 to endure 300Gs of operat-ing shock, 1,000Gs of non-operating shock and 600,000 load/unload cycles, contributing to the Travelstar E7K100’s highly durable and rugged design. This combination of capacity, performance and shock tolerance enables the E7K100 to satisfy the demands for rugged, reliable storage in non-stop environments."

HTE721010G9AT00 Operating:
Ambient temperature: 5° to 40° C
Shock (half sine wave): 300 G / 2ms, 160G / 1ms


HTS721010G9AT00 Operating:
Ambient temperature: 5° to 55° C
Shock (half sine wave): 300 G / 2ms, 160G / 1ms


I would go for the Momentus just for the fact of the extra 2 yr warranty. The hitachi is faster though. Also, check out NBR for the latest head to head write up with a comparison of the seagate and hitachi 7k100 drives...

Hee...theres another article out there, i think its tomshardware that did the comparison first. No worries..happy reading and enjoy your 7k100 !!!

may i ask what OEM means?

Original Equipment Manufacturer. Same item, no pretty box. Marketed for system builders, *usually/sometimes* has a reduced warranty because it's designed for the company building the systems to cover the equipment.

AHHH U HAVE ENLIGHTENED ME!!

Thanx alot! Its always nice to have someone help me out with terms :-)

I'm still wishing we'd see 120 and 160 in 7200 rpm drives. The promise a year ago was that perpendicular tech would double capacity and at that time we had 80gb 7200's.

So much for press news haha

power, if it matters to you

there may be a difference in power too, I know my 80gb 5400.2 momentus does 0.46Amps @5v and my 80gb travelstar needs more juice (too lazy to remove it, its the main one just now)

Is anyone cautious about buying OEM hard drives (or memory while on the subject)?

I stopped in a small shop today that builds desktop PC to order, and sells the usual hardware and components. Was curious what notebook hard drives thay had. They showed me several, all of which were wrapped in the grey anti-static film, but with no manufacturer labels or markings on the outside film. In the back of the store, there were teo small machine that put te grey film on small items like the hard drives, kind of a neat little device is you sell things this way.

But, it made me think how they order and receive these hard drives (and memory modules). Most likely in some bulk packaging, designed for easy of use on a factory floor/high volume assembly environment, rather than each unit wrapped individually. Any thoughts on this?

Surprised no one else has noticed the "100MB" in the post title... I think 100MB hard drives died out around 10 years ago :P

I didn't even know they're building 100MB disks now! that's huuuge. :P

That's the point. These things (disk drives, memory modules) are in sealed static bags, but not necessarily from the factory. I'm curious and suspicious of sellers that purchase in bulk, who get their products in a crate or box, and then seal the units in static bags themselves.

As I said in previous post, I saw that happening today. They had a machine that fits on a desktop that seals parts in grey static bags, sealing then looks professional and all that, but raised a few red flags with me.

Also, the 7K100 has HiVERT™ in its product description - short for Hitachi Voltage Efficiency Regulator Technology, a novel power-saving technology that works in conjunction with Enhanced ABLE to significantly reduce power consumption by the hard disk drive without sacrificing performance characteristics of the base design.

Since my notebook is not a round-the-clock server, I decided that the HiVERT feature made the 7K100 a better choice for my notebook.

I bought the E7K100 thinking it was the higher end drive. Guess the "none E" is the correct choice for laptops. Though, I have not had any problems with it yet.
