Indeed it does! At least in my case. Running my system in UEFI mode, not legacy though...

I want to know if installing a 1 TB SSD Drive in SATA bay can produce energy / current drain problems to internal power circuitery.

A standard 128 GB SSD drains 0.3 A at 3 volts = 0.9 Watts, a Segate Momentus XT Hybrid 750 GB drive dains 0.7 A at 5 volts = 3.5 Watts, but a 1 TB SSD Samsung 840 EVO drains 1.4 A at 5 volts= 7.0 Watts eigth times more than the basic configuration.

Hi,

I know that the initial question is answered... but I will reuse the same forum to ask a question about mSATA SSD devices.

I have the E7440 shipped with HDD. I just bought a new SSD  INTEL 530 at 120 GB with mSATA interface.

I could plug it in just fine in the mSATA port-  WWAN. 

However, BIOS does not recognize it at all. Is there any trick to activate the mSATA port to put the SSD device? I did reset BIOS settings to default, I even upgraded from A08 to latest, A10 - but still no luck.

Any hint would be most welcome.

Thank you,

Stefan

Hi,


Coming in very late: when you say "standard HDD frame" do you mean the one that is fitted with the Dell 5mm drives with the rubber spacers?

The only thing I'm worried about is the lack of mounting holes for a 7mm drive - do you just shove it in and let it sit there?


Cheers!

Tim

I am running a 7mm HDD from Hitachi in my E7440, without any problems. The fit is so snug, there is no need for screws. A frame/bumber wouldn't even fit - it's that snug. Just go for it!

Just info for other more punctual people like me. For us this solution is not acceptable 

HDD is laying on bottom _plastic_ casing. HDD can emit heat and I am not sure if long-term exposure of plastic casing to weight and heat can't deform it in some minor way. This casing is not made for holding (absorbing weight) of anything.

Dell wouldn't use more expensive smaller drives if use of 7mm drives would be without compromises.

7mm HDD is not fixed in bracket so it could shake freely (gap about 0,5-1mm total).

Yellow flat cable on bottom of bracket can't be made truly flat so drive could deform it (5mm drive would made some space for it because of rubber rails).

I hope my shop will take back 7mm drive i bought and I will try to get proper solution then.

I am not an engineer so I don't know how much big this problem may be in longer future. But for me this notebook is quite expensive and REALLY WELL MADE, it's really a shame to devaluate this technological marvel by inferior "tuning". Just my two cents :P

Hello,

a rather unpunctual reply from me ; )

Well, 5mm drives are okay for music libraries and maybe movies, but not much more, since they are really slow. Plus they only come in limited capacities. And from experience (I am using a 7mm HDD for 3/4 of a year now) I can say my Hitachi Z7K1000 works very well in my E7440. No deformation or heat issues.

The yellow cable indeed can get a little pressed and/or bent. So what. It's a cable. (And again from exprience: all is good.)

But funny you even bought a 7mm drive for your E7440 - after you've read this thread here? Because in many posts it says there is no proper mounting for it in the computer. The "devaluation of the technological marvel" was a given!

Cheers

I am really not saying that one solution is good and other is bad. I think that 7mm hard drives probably won't break anything even in long term.

I know that 5mm drives are even slower than 7mm. Moreover max capacity is 500GB instead of 1TB.

But let's not hide the fact that this is not professional solution, hdd can freely move and is held just by thin plastic.

I probably have just not taken seriously enough those many posts you were talking about.

In reply to MATZEXXX's post:

Just to confirm; you say you were able to use a 7mm 1TB 2.5" HDD and a 256GB mSATA SSD drive both on the same E7440?

Is this actually working? Were there any bios or software problems? This sounds like a hot set-up and "good job" to you for trying and sharing.. Thanks.
