Re: T61 Support SATA II ?

2009-05-10, 14:57 PM

Of course I am assuming, if I knew exactly what was going on I would probably do something about it, wouldn't I :-)

 

Given all that was written on the forum, I'd say that SATA300 is disabled in BIOS only, but the reasons for such action remain

unclear. If there indeed is an issue with the bay adapter, I guess there won't be an update, but if the reason is battery life

then I really don't see why there wouldn't be an extra option in BIOS to enable SATA300 at battery life's expense.

 

And if what you're saying about "community issue resolving" is true, then I really don't see why am I bothering writing here.

 

Only 8 months ago I paid ~$1400 for a laptop that touted SATA300, and instead I got SATA150.

Now when it became a real issue and a feature users actually want, all we can hear (from Lenovo fans, not officials!)

is "buy a new ThinkPad".

 

Good bye Lenovo, and thanks for all the fish.

@amastilovic.... T61 that you got was unsold stock, you paid $1400 for a T61 in USA? 

 

I don't think Lenovo ever advertised that the T61 supported the full SATA 300 mode.

By the way, from your signature I see that you have a T400. Does your model have SATA300 enabled?


I don't know. I never tested it. It is not very important to me. I don't crunch big projects with it.
If I get time soon I will test it. Which particular test do you want me to run?

No, they just say SATA2 support.

However, they also did not mention this is SATA2 compatible mode only. (ie not full SATA2 support).

 

This is same question as USB2 and USB2 compatible mode support question. Just think of you bought a USB2 (but not USB2 high speed support device) ! - ie USB2 device actually running at USB1 speed !!!

Re: T61 Support SATA II ?

Well I guess it's right that we all read sata2 and so believe in the good sense and trust in tradition that lenovo has good engineers,

I'm afraid that instead of that we not only get sata1 and we all complain about an update,

but the bizarre response of lenovo is turn of the update system. So now we can't make the updates but manually.

My question is are they thinking in to close the company?

I just give up of waiting for the update and get (still waiting) a new multipart mechanical hdd, but with 500 gb

That is what I wanted before knowing about the new ssd.

So quite happy to forget every issue, It becomes that if I don't clone the disk I'll need to download and install all the updates myself last time I install everything from 0 I had to download and install about 1gb of updates and drives etc. From lenovo. That took a very long time, and I had run the system update several times and restart... Etc. So doing that manually I guess is work for a technician with plenty of time to do it.

So my English is not good enough to say that I fill a worse than disappointed.

I called lenovo and has no answer to say why the move out the update system but just say do not wait for it again.

I recently installed a OCZ Vertex SSD capable of reads of about 250 MB/sec.  But in reality, it will only read at less than half of that rate on my T61P.  This is way under the SATA1 standard of 1.5 GB/sec., is it not?????  Why should we need a SATA2 transfer rate of 3 GB/sec? 


The 1.5 Gb/s specification is in bit/s. I believe SATA uses a 10bit/byte encoding so 1.5Gb/s translates into 150 megabytes per second. This is of course the theoretical maximum so the real transfer rate is a little below that. This is where the limit comes in.

Hi - no need to get upset.

 

Spend ~290 € incl. tax for 80GB ? Newegg US $ 325

This is the current price of Intel X25-M SATA Solid-State Drives

 

Performance tests of the latest high quality SSDs (Intel, Samsung) reveal rather disappointing random write transfer rates under heavy load and when disk capacity has being used above ~80% and when workload characteristics change.

 

Ref.: c't 11, 2009 / (c't is the leading german computer publication) http://www.heise.de/ct/inhalt/2009/11/100/

 

http://www.pcworld.idg.com.au/article/302571/ssd_performance_--_slowdown_inevitable

http://www.techworld.com.au/article/299310/intel_offers_firmware_upgrade_ssd_performance_problem

 

Check out prices for those high performing notebook disk drives and balance speed with price and capacity

Seagate Momentus 7200.4 500GB 7200rpm
Western Digital Scorpio Black 320GB 7200rpm

 

These drives barely saturate a SATA 1.5 Gbit/s link

 

http://en.wikipedia.org/wiki/S-ATA#SATA.2F300

 

SATA II misnomer

Popular usage may refer to the SATA 3 Gbit/s specification as "Serial ATA II" ("SATA II" or "SATA2"), contrary to the wishes of the Serial ATA International Organization (SATA-IO) which defines the standard. SATA II was originally the name of a committee defining updated SATA standards, of which the 3 Gbit/s standard was just one. However since it was among the most prominent features defined by the former SATA II committee, and, more critically, the term "II" is commonly used for successors, the name SATA II became synonymous with the 3 Gbit/s standard, so the group has since changed names to the Serial ATA International Organization, or SATA-IO, to avoid further confusion.

Re: T61 Support SATA II ?

What are you trying to say? That SATA 3.0 Gb/s is pointless? SSD are a waste of money? The slowdown on the x25-m has been corrected by a recent firmware update. There are also cheaper (but also very fast) alternatives such as the OCZ Vertex, GSkill Falcon, Crucial, and more are coming out. They are more expensive on a $/GB perspective compared to rotational disks, but ask yourself how much data do you really need on your laptop all the time? With this much competition the prices will drop.

 

Really there is no comparison between the performances of good SSDs vs. rotational disks. Even with the crippled SATA bus, upgrading to a X25-M has significantly boosted the performance of my T61p (I chose the Intel over other comparable SSDs for reasons other than speed). The sequential read speed is severely handicapped, but fortunately that's not a typical usage scenario for me. The random 4 KB read/write performance do seem to be affected also. The read appears to be 66% of what I see in reviews and the write ~50% (13 MB/s and 19 MB/s are what I get). Note that the read is not scaled linearly with the bus speed. It's fast enough, but definitely could be faster.
