TRIM watch

Not having TRIM wont put your data in danger. It should reduce the performance degradation seen pre-trim over time as the drive fills with data. The update is optional ;)
 
Ok, I knew the data was safe - but in practice, am I genuinely likely to actually notice the degradation - are we talking tens of seconds or just the odd second?
 
I just updated firmware - one of the easiest upgrades ever - very happy (even though am not convinced my life is going to be revolutionised!)
 
Question re trim.

I have entered this "fsutil behavior query disabledeletenotify" and am returned "0" so Trim is enabled.

I have also seen it stated that the drivers must be Microsoft - which ones?

A crucial forum post said, "if you go to device manager and double click your storage provider and click driver. If it says the drive is provided by Microsoft then trim is supported by the driver."

Can you explain which Driver you mean there are two options:

Disk Drives -- Crucial device
This shows Microsoft 21/06/2006 Version 6.1.7600.16385

OR

IDE ATA/ATAPI controllers
-- there are 3 ATA channel 0 and 3 channel 3 entries with microsoft drivers
-- there are 2 x ICH10 serial ATA controllers with Intel drivers

Please advise which ones I should be looking at? Thanks, Mel
 
AFAIK the "Standard AHCI 1.0 Serial ATA Controller" and x6 "ATA Channel"s under "IDE ATA/ATAPI Controllers" are the native drivers. That is, the ones included as default/fresh installation.
 
Added GSkill to the first post, as reported elsewhere on the hd forum.

Intel firmware is still down, no eta.

Well I am still not convinced. I had run the "Install m/b drivers" Gigabyte CD, after the Win 7 install so I was not sure if I had installed extra Intel drivers. So I "rolled" back the Intel drivers on the Controller and they ALL now say Microsoft 6.1.7600.16385:

These last ones said Intel (see above) before I did the roll back.

Is this what other people have who have a Win 7 install with NO extra drivers?

And THUS is TRIM working - I have NO idea..............

Well I set it up for ACHI but when I rolled back to the m/soft drivers it reverted to IDE - daren't change it back again to ACHI again in case it won't boot ! Do I need to though!

What drivers show for the AHCI row?
 
I remember reading a guide somewhere ( I think its in this forum) that you should install windows 7 in IDE mode then afterwards change it to AHCI mode and do a simple edit in the registry. I can't remember exactly what/why hence the bland explanation but I did it and its running fine.
 
Just bought a brand new samsung 128GB SSD from a mate for £180.

Are sammy's able to update their firmware for trim ?

Totally new to SSD's, so excuse my ignorance.

Thanks.
 
I'd be interested in knowing about the Samsung also as I'm about to pull the plug on an SSD for my N110 and would prefer a Sammy one if it is a good choice?

Thanks & kind regards,

At present end users cannot update firmware for Samsung PB22J's. There are at least 3 different firmware revisions on drives, none of which support TRIM. Later versions of the firmware support Garbage Collection.

No announcement has been made as to whether Samsung is working on a new firmware to support TRIM, or whether end users will be able to update their firmware, though there have been some rumours that it may happen.

The Intel Atom chipset only supports SATA150. This will seriously bottleneck performance of any SSD in a netbook. There will be an improvement, but it is no where near as significant as when used in a SATA300 equipped machine.
 
Thanks for the reply CL,

I hear what you say about TRIM, GC etc. but am getting got fed up of waiting TBH.

Regarding the SATA150 comment - I also have an IBM X41T TabletPC (Pentium M 1.6GHz) with notoriously slooow 60GB 1.8" HDD that I had stopped using due to its excessive boot-up time and painfully slow operation of everything! Even the cursor could not keep up with moving across the screen sometimes!

I fitted a genuine IBM 60GB SSD (that has not even heard of TRIM) and this machine has taken on a new lease of life - it has become a dream to use.

Everything flies, boot-up times can be counted in seconds and not minutes and it is now quicker than my desktop!

This definitely does not have SATA300 but the performance increase is staggering so I believe this SATA150 seriously bottlenecking the performance 'myth' is something I could happily live with if my X41T experience is anything to go by.

People place too much importance in theories & benchmarks IMHO and although I would concede that SATA150 may theoretically bottleneck the SSD one has to take into account the huge improvement over the original SATA HDD in my X41T and not dwell too much on its percieved performance deficit compared to SATA300.

Thanks & regards,

Hi Glyn,

It's certainly not a myth :) I've an eeePC with a Samsung PB22-J and it's running half the speed it is capable of in some circumstances, capping out at about 130MB/s and this is very noticeable when put alongside a SATA300 equipped machine with SSDs.

The reason for mentioning it, is if you haven't already bought one, you may be better off with a cheaper, lower performing SSD and achieve the same results as a more expensive drive which can't work to it's full potential.

Just trying to save you some money ;)
