Latitude E6510 Owner's Lounge

I thought the SSD issues are with the SATA minicard slot/BIOS, not the HDD bay.

Not having any experience with accelerometers in laptops, can someone correct me if I'm wrong in thinking that the accelerometer is separate from the hard drive and doesn't come as a part of a special hard drive?

I am thinking of upgrading to the WD 750GB Scorpio Black but I want to make sure the motion sensor still works with that.

Also bought the caddy off ebay, I'm assuming there's no accelerometer support for that.

 

The accelerometers are basically manufactured on a semiconductor process, and are chips that are on the hard drives themselves.

 

The E6510 'accelerometer' is on the motherboard and requires a Dell driver. Use any HDD you want.

So does that extend to any number of drives connected or just the primary drive?

 

I assume the MB-based accelerometer instructs the attached HDD to 'park it NOW!' when notebook acceleration is detected. Not sure through how many connectors/controllers that instruction would get sent. Would it make sense to manage eSATA external HDDs the same as the onboard primary HDD with regard to dropping the notebook?

I guess it may to some degree. But my question is with reference to the caddy I have ordered. That is something that would definitely benefit.

 

Can't be sure without asking Dell or similar.

I recently bought an Intel 320 300GB SSD for my E6510 bought a year ago, did a BIOS update, enabled AHCI and installed 64 bit windows 7 on it. Now, can I be sure that my AHCI driver supports TRIM and that it's working?

(I did the usual test, but apparently it's not reliable: DisableDeleteNotify is 0)

 

I have set up the caddy bay with the HDD from a WD portable 640GB (Scorpio Blue 5400rpm 8MB cache) drive that I had and it works like a charm. Read and write speeds are great and I've no problems streaming HD content from that drive.

I'll test the read write speeds properly once I have some time, but right now I'm happy.


I'm going to test out the battery life soon. I think I need to play around with hdparm and configure the second HDD to spin down quickly.

I'm not sure if windows/ubuntu allow me to do this, but I'll keep you guys posted.
