Solid-State Drives (SSD)

[kallogan]

It's no use blaming Crucial...It's not the end of the world. The drive's still running and nobody forces you to upgrade your firmware since it originally works fine. Make yourself a favour and downgrade to 1571 if you're not happy people...You guys aren't very resourceful sometimes...always cryin'. That's how computers work especially with new tech. Besides Trim is overrated and not that indispensable.

Fine, but what about the question of whether or not it is OK to use 15xx until Crucial gets the product working? Is there any comment on this from Crucial?

There are people on this forum who have reverted to 1571 and seem more than happy.  If you need a response from Crucial support it's probably best to contact them directly as Maulmod suggested.  If you click Customer Service in his signature it will take you to a screen where you can select your local support then you can email them or use an msn style live chat with them.

uneverno,

As targetbsp said, many other users have either not performed the update or reverted back to 1571 and are happy with this.  It really depends on your system and what your needs are which version you want to run with just now.  The latest firmware fixed a lot of bugs which are detailed in the Release Notes on the firmware update page so you would not benefit from them if you go back to 1571.

You'll also notice going through the various threads that some users have updated and do not have performance issues so a lot of it depends on the hardware configuration i.e. what chipset, processor etc is being used rather than it being an issue with a particular drive or firmware revision.

The feedback we've been given has been passed on to our lab so we can investigate and we'll report back with any findings.  We understand that with your SSD, you want all the features and functions without compromising performance.  Please keep checking the community for any updates and advice from other users, as they have proved to be really helpful so far.

It's been over a week or so and  I haven't heard anything back from Crucial about this potential issue.

Have you been able to reproduce the problem some of us are having?

Is the issue specific to a chipset?

Is the issue specific to 64 bit or 32 bit?

Are we missing some kind of step to keep the performance at max?

Is the write performance drop just a side effect of TRIM in the new firmware?

Please, some additional information would be helpful.

Here's another question. Does FW 1571 natively support the ATA-TRIM command? If I just go back to 1571 can I use Windows 7 to TRIM instead of using the wiper.exe program?

[targetbsp]

1571 does not support trim.  Basically the big new thing with 1819 is the Windows 7 trim support.

[Tekno]

Well, I think 1571 supported some form of TRIM which is what the wiper program sends to the drive. Wiper queries the OS to learn which blocks are free and then it sends a TRIM like command down to the SSD. I have read reports from some people that it's a proprietary TRIM command and then I have read from others that it's the official ATA-TRIM command. If it's the official command, I don't see why I couldn't just use Windows 7 with 1571 to get TRIM support. However, if it's a proprietary TRIM command I will be forced to use the wiper program. I just can't find any definitive articles on this matter.

[targetbsp]

Err what? :S Where have you read reports that 1571 supports trim?? The whole point of firmware 1819 is to add ata trim support. It says so in the changelog and they spent 3 months programming it.  It would have been a bit of a waste of 3 months if it already supported it.  Remember that while Windows 7 is new out a lot of users have been running it since august and I've not seen a single claim here or on the ocz forums (with their equivalent fw 1.3) that trim works.

[edit]

there was an older firmware, 1711, that was both fast and supported trim but was withdrawn because it trashes your data.  Are you thinking of that?

[edit2]

If you are just querying the fact that wiper uses the word 'trim; while it;s running then see towards the bottom of this article: http://club.myce.com/f138/ssd-faq-297856/

"Basically, it creates a large file on the drive, which fills a large part, but not all of the free space on the drive. It then deletes this large file and sends an (Indilinx exclusive) garbage collection command to the drive,"

So it's definitely not ata standard trim. hope this helps.
