Thinkpads Forum

Hi all,

finally I got one of those hyped SSD drives for my T60p.
(Samsung 32GB MCAQE32G5APP)
I was very exited because I use my 2nd Harddrive for development purpose (vmware, eclipse, oracle jboss).
Initially I thought this will give me a huge performance increase because of the access time which is < 1ms.

So after doing some tests I am a bit disappointed because the performance increase is not as I wished.

My experience is really more from a day to day usage. I did not do any benchmarks because you can find them on the internet.

Here are at least some numbers from my stopwatch, by comparing the same setup on the SSD with a 7K100 ibm drive:

Starting eclipse
7K100: 11s
SSD: 7s

Loading about 9000 objects into eclipse memory:
7K100: 1:45m
SSD: 1:20m

Executing about 500 XSLT transformations and executing 500 sql scripts against oracle:
7K100: 2:18m
SSD: 2:25m

restarting jboss:
7K100: 1:18m
SSD: 1:13m

So as you see, it is a bit mixed.
It is really interesting that the low access time does not give that much of an improvement, even though thousands of files are read in the test above. I can only guess that the cache/high seq. transfer in the 7K100 combination does an awesome job.

But if we think about that this is more or less the first generation SSD which is targeted for mass production, it is pretty impressive.
Wait one more year, and hard drives have only one advantage: space.

Regards,

Wolfgang

so now you don't need APS

I wonder how the power consumption compares.

It looks like the SATA version is still not yet available.

The power consumption is about 1/4 of the 7K100.
Idle is 0.1 and active is about 0.5 Watt.

One more thing in regards to performance. The system feels kind of strange. The windows startup and application load is really much faster than the 7K100, but then you have always these very short delays while working, e.g. scrolling in the file explorer, writing text in editors ...
I can only assume that the missing hard drive cache is the issue here.

In the meanwhile I am not quite sure if I will continue using the SSD or if it goes to ebay.

Great post. Good to see some numbers with real day-to-day apps than some synthetic benchmarks. Were you able to actually measure a faster boot time for windows, or you just felt it was booting faster?

And the important questions: how much did it cost you? what was your opinion about heat and more importantly, HDD noise? Was there any noise at all?

Thanks freakwave very informative topic.

Could somebody tell me, in rough terms, what proportion of total power consumption this accounts for? What kind of impact would it have on battery life?

1/50?
impact is slim

The big power eaters are CPU and LCD

Thanks a lot. The reason I ask is that I was considering getting a hybrid drive for my machine once they come out.

There are also something else available nowadays. Check the following link: http://www.dvnation.com/nand-flash-ssd.html. Note that Transcend has SSD in the form of ExpressCard. I am not sure if Thinkpads can boot from ExpressCard devices, but even not, one can still use READY BOOST (is this the correct terminology?) to improve the battery time and the preformance (probably). As somebody already mentioned, the most power eating devices are CPU and LCD, so I doubt if one can really increase the battery time using ExpressCard solution, since ExpressCard also eats some power.

By the way, since I have a X41t, I am always waiting for a 32GB 1.8" IDE SSD in order to improve the performance. Can freakwave tell us how much you get your SSD, and probably also where?

Hi all,

I will try to get some windows startup comparison over the weekend. A first guess would say that the windows 2003 server in vmware starts about 30% quicker.

I bought the ssd from overclockers for about 300 Pound:
https://www.overclockers.co.uk/showprod ... =HD-043-SA

If you are in the US you can get it cheaper from newegg (488 USD), but I think it is out of stock:
http://www.newegg.com/Product/Product.a ... 6820147015

Hard disk in general makes up around 3-10% of total power consumption at the very most... Check out this article for a break down of power consumption in a thinkpad R40. The biggest players as previously mentioned are the CPU, LCD, LCD backlight, and the graphics card. Don't expect to double your battery life by switching to SSD.

Specs say read latency is <1ms. It would seem that write latency is much worse. But how much worse?
In any case, interesting first impressions. Thanks for sharing.[/b]

To me it looks like the model freakwave use is an IDE one, not a SATA one. How do you connect an IDE HDD to you T60p? I am just a bit curious about it. Probably you use some converter and a 15" T60p is big enough to handle that converter.

Oh... I think of one way of doing it. Are you connecting through the old version of ultrabay slim 2nd HDD adapter?

Guys, this is JUST THE TIP OF THE ICEBERG.

All the major SSD manufacturers have announced substantial speed increases (3X or so) over the course of the next year for sustained data transfer rates (access times will remain VERY low). Couple that with the inclusion of SATA2 into laptops and we are in for a real TREAT in terms of performance in the next few years.

Does this mean our current SATA could be used (perhaps via some "retrofit" or bios update), or are you implying SATA2 would have to be built into the new yet-to-be-released notebooks?

Thanks, R.

The T60 already has SATA2

Got a link to back that up b/c I was under the impression that Intel's southbridge on laptops was a SATA1 controller.

Sry, don't have a link, but mine supports NCQ with my new Samsung Drive and that's a SATA2 only feature

cu

According to Intel Hardware specification for the ICH7 (page 46) the ICH7 implements the SATA I(1.0a) specification and some optional features from the SATA II specification. So, current Intel chipset (945) only fully supports SATA I, not SATA II.

oh, ok, sry, but wich Features are not Supported?
