how hot is your e7k60?

I8kfanGUI on my i8600 indicated that my hitachi e7k60 temp hovers around 46C~48C. my laptop is running mostly 24/7 at home and i set the accoustic and power management lvl to max performance by using hitachi feature tool. i read some people saying theirs never go over 40C. if you are one of them - how do you do it?

I am looking at getting this drive, and I've been speaking w/ Hitchai about the two versions of it. Here's the reply I got this morning:

FYI:

Here is the reply I received from Hitachi regarding the E7K60 vs. the (non-E)7K60, and using the Hitachi tool to enable power management:

"The operating temperature specification is correct. The 7K60 has an operating ambient temperature of up to 55 degrees C whereas the E7K60 has an operating ambient temperature of up to 40 degrees C. The reason ties into your next question. The operating ambient temp is lower on the E7K60 because the E7K60 has power management disabled. Because it is disabled, it is not able to spin down to stay cool, requiring the drive to be run in a lower ambient temperature.

Using the Feature Tool, you can enable power management on the E7K60; however, it is recommended that for laptop use, the 7K60 is used instead."

What that boils down to is that the E7K60 should be used in cooler environments; however, the tech basically said you can use the tool they provide to enable the power management, making the E7K60 into a (non-E)7K60.

I have sent a reply to them asking them to clarify, and I'm waiting for a response.

its prob the same drive with a jumper or something set inside to turn the power feature on/off

Yes a logic jumper in the form of a firmware that is flashable.

So, with power management disabled, the regular 7k60 would *theoretically* run at a lower operating temperature as well?

If I'm not mistaken, ambeint temperature is the heat range the drive is certified to work -in-, not the temp it actually runs. The E7k60 has less tolerance for heat than the 7k60.

Here's the response/clarification I got from them:

"Unfortunately that is not correct, The E7K60 is designed for blade servers and does not have the power management functionality available at all. I would recommend searching in other places than Dell to purchase this drive.

Its is possible you will find it considerably cheaper elsewhere. You want to search for part number 08K0939, we link to resellers on our website here: http://www.hitachigst.com/hdd/buynow/buy_tr7k60.html"

I just sent him another email - since he contradicted himself in the two emails. I said:

"Wait, in your first email you said: "Using the Feature Tool, you can enable power management on the E7K60; however, it is recommended that for laptop use, the 7K60 is used instead." But in your response just now, you say that "...(the E7K60) does not have the power management functionality available at all." So which is it? If I can use the Hitachi tool to enable it, then it must be there.

He hasn't replied to that email yet.

edit: Also, when I asked about flashing the E7K60 with the (non-E)7K60 to "enable" the power management features, he replied with:

"Unfortunately that is not possible and any drive that it was attempted on would have a voided warranty."

I'm curious as to what impact not having power management on the drive will have on battery life. It seems that the biggest impact to battery conservation is going to be shutting down the drive when not in use. That's a function of the PC's bios and not the HD, correct (I know I can power down my hd's in my desktop and they don't have power management functions). If that's the case, then power management functions on the drive will provide incremental power savings over the bios controlled functions. How big of an impact will that be?

he recommended the one for the laptop, there make hds test hds and they recommend it.. i think we should stick 2 the recommended option for this.. order the 7K60 its made for laptops
E7K60 is made for servers

a whitepaper on ABLE drive power management:

http://www.almaden.ibm.com/almaden/m...rd_drives.html

This is what you gain by going with the 7k60 vs. the e7k60. 7-10% improvement in battery life vs. the same drive in a benchmark scenario. Probably less in real-life usage. Assuming 5% in real life, you'd gain 9 minutes of battery life on an average 3 hour battery.

my impression is that e7k60 is advertised not just for blade servers but also for laptops. i choose it mainly because my laptop is running 24/7 except when i unplug it for travelling. i also send e-mail to hitachi tech support. hopefully i'll get an answer soon.

Its a gimmick. There are two markets, server markets and home markets. Home markets can pay more than server markets which are more competitive.

I bet the two perform exactly the same, its just a monopolist's way of dominating the market and selling at 2 prices.

Hitachi is far from a monopolist in the HD market. They may own the only 7200rpm 2.5" drive right now, but there are plenty of alternatives.

That said, I otherwise agree with you. My take is that a drive in a laptop is more prone to failure than a drive in a server, since the laptop drive is subjected to constant starts, stops, power up and downs, drops, etc. This makes it more expensive to warranty a 'laptop' drive instead of a 'server' drive - so Hitachi charges more for it. I would be really surprised if there were any true hardware differences between the two drives.

Woo-Hoo! I just checked the Dell Home site, and the (non-E)7K60 price dropped! Last week it was 10% off, this week it's "Dell Home Customers: Save 15% off Storage and Drives!"

It's showing as $174.95 - $26.24 discount = $148.71!

I still have my $25 off $150 coupon, and the system is letting me use it! SWEET!

That makes the drive come out to $132.37 after tax and free shipping!

I just placed the order, since ~$130 was my trigger point - I was prepared to spend the $156 to buy this at ZipZoomFly.com, but I'm glad I waited the two days to see what specials Dell had this week...

Sorry, the $25 off $150 wasn't a public coupon - it was a one-time use coupon I had.

this is the e-mail i got from hitachi:

The E7K60 was designed more for Blade Servers than laptops. This drive
has
Advance Power Management disabled, so the drive is constantly spinning
which creates more heat. It can not be enabled. Acoustic Management
will
not work either.
I have looked into your situation further. The ambient operating
temperature for this drive ranges from 5 Degrees to 40 Degrees C.
However,
I noticed more information as well. The system is responsible for
supplying
sufficient ventilation to maintain a surface temperature below 50ºC at
the
center of the top cover of the drive and below 53°C at the center of
the
drive circuit board assembly.
We would like you to run a different program so we can see what the
SMART
values for temperature are. Two such programs are Active Smart and Hdd
Health. They can be found at the following links:

http://www.ariolic.com/activesmart/index.html
http://www.panterasoft.com/

If you can run these programs and provide us with the data it gives
you, we
should be able to give you a better answer to your questions.

Interesting...well, the point is moot to me since Dell dropped the price on the (non-E)7K60 drive this week, and it's actually CHEAPER than the E7K60 drive. I paid $132 shipped, and that's about $2 cheaper than the E7K60 drive from them last week, so I'm happy.

ARGH...My E7k60 just shipped, and now the reg (better?) 7K60 is cheaper...I wish there was a way to return/refuse and still get my one-time-use 25 off 150 coupon to use to buy this one.

ARRRGGGG! I just checked my order status this morning for my 7K60, and the status has changed to "Currently one or more items are backordered. Every effort is being made to complete the order." Yesterday it said it would ship on time. :-(

I guess people are ordering this left and right now...

Maybe I'll try to get a Dell concession coupon out of it.
