T61 Turbo Memory Cons & Express Card Option...

2008-03-08, 5:48 AM
Was just reading a thread discussing the stability of 32bit vs 64 bit Vista OS and it seemed to suggest that Turbo Memory is a bad thing...that it was a de-stabilizing influence to the system, is this true? Is Turbo Memory a bad thing?
 
I just placed an order and for other reasons was thinking about cancelling it to make a modification to the system. Should I also tell them to also remove the Turbo Memory selection I had made?
 
If TM does creat a problem, what problem does it create?
 
Are there any benefits to TM?
 
Also,
 
I had chosen the memroy card reader over the express card option thinking that if I wanted an express card I could just get a USB express card version later (more versatile as I can then use it with any computer). I have since been told that the express card gives more options in that it ihas direct access to the system bus at 2.5 Gb/s, with zero CPU overhead. Much more powerful and versatile than USB...that a memory card reader "sleeve" could actually been inserted if desired.
 
This being said, does the express card option sound like a better decision?
 
Thank you very much!

IMO, no.  Until Intel gets its act together over proper Turbo Memory support, its a waste of $$$ and space

Hello,
 
Right now, the main advantage to Turbo Memory seems to be slightly better battery life and application load times, especially on systems which do not have much memory installed on them.  I suspect that will improve over time with updates to Windows Vista and drivers from Intel, but unless you are purchasing a ThinkPad with a minimum amount of memory or are planning on using it almost exclusively on battery then there is probably little advantage to getting one right now (other than saving yourself the hassle of having to install it at a later date). 
 
I have a Lexar 4GB Express Card SSD in the ExpressCard slot on my T61p, however, despite the name, it is actually a USB 2.0 device in an ExpressCard/34 form factor (the ExpressCard spec is actually just a 1xPCIe connector and a USB 2.0 interface together).  It seems to work just fine with ReadyBoost, although I cannot say I have been able to see much performance improvement from having it in place.
 
If your model of ThinkPad has the 4-in-1 card reader build into it, you could possibly stick a memory card in there for use as a ReadyBoost device.
 
Regards,

Thank you both for your replies, I really appreciate your help!!
 
From what you both have said, it does not sound like Turbo Memory really causes any problems, but it is more of a question of whether or not it is of much value...at this time. If it doesn't destabilize the OS, and there is talk that in the futrue there may be some benefit... for $30 maybe it would be easier to add it now and then just forget about it with hopes that maybe in the future its benefits would become realized by future Vista improvements (...as goretsky you mentioned).
 
It does sound like the Express Card slot would be better than the getting a memory card reader...I will make this change.
 
If I could ask one other question...what exactly is the difference between a T61P and regular T61? I have been clicking every link on the Lenovo site and have not been able to find anything that really explains it. About the most I have been able to determine is that the "P" does not have the 14" WXGA+ screen available but a 14" SXGA+ instead...(this is not a wide screen, right?).
 
What are the other differences?
 
Thank you very much!!

Just asking, what are the differences when using TurboMemory vs Readyboost with a 1 GB SD card?

Hello,
 
As I understand it, "p" series units have faster processors and upgraded graphics over non-p units.  The ThinkWiki site has  entries for the T61 and T61p which you can view to compare the two.
 
The 1GB Turbo Memory card is split into two 512MB sections, one of which is used for ReadyDrive, the other ReadyBoost.  A 1GB SD Card, however, would function as a 1GB ReadyBoost device, with no ReadyDrive capability.

Thank you Goretsky...that makes sense!
 
Sorry, one last question if I may...
 
Currently I was planning on getting the 160GB HD 7200RPM. Now I wonder if maybe I should consider the: 200 GB Hard Disk Drive, 7200rpm with Disk Encryption. It would be $127.50 more... but would the encryption aspect (plus additional 40 GB) make it worth it? I have always been hesitant to do banking and personal finance related work on my laptop for this very concern (laptop theft)...would this encryption element be a good idea to help protect this info (for a computer that I will carrying around all day (city, university, etc)?

Apart from the additional expense, the other concern I had about going the encryption route was...if a had a hard drive crashes and/or files were lost through an accidental delete (as I did this past Fall...miserable experience)...would this type of HD make it more difficult (or impossible) to recover data from?

Thank you!!

Hello,
 
Unfortunately, I am not familiar enough with the Full Disk Encryption technology to be able to answer your question, but perhaps another forum member who uses it or one of the staff can tell you more about how it works and the pros and cons of implementing it on your ThinkPad.
