Davyc Posted September 8, 2009 Share Posted September 8, 2009 Hey there - firstly thanks to Bluebeard for posting the new FAQs for both style drives .... I'm curious about the Trim feature in Windows 7. I'm running RTM Pro and Trim is enabled, so I ran the CrystalDiskInfo program and it reports that Trim is featured in my X-64 drive (see image below highlighted in yellow); is this correct or just another false-positive from the software? It also reports that I only have 32mb cache, which is obviously wrong lol. Any clarification on this? http://www.ppsuk.com/capture2.png Link to comment Share on other sites More sharing options...

RAM GUY has previously confirmed to me in an earlier reply that Trim is currently supported in Firmware 1.0 on the Extreme drive so the newly posted FAQ is an apparent contradiction of this (I am running Win7 Ult 64bit RTM). We are also awaiting Corsair's findings on the cache issue that was highlighted last week by dbw09. Corsair staff found the same 32Mb reading but when they took the drive apart it had 64Mb. I expect some further advice on this in due course from RAM GUY. Link to comment Share on other sites More sharing options...
Davyc Posted September 8, 2009 Author Share Posted September 8, 2009 Thanks for the heads-up - much appreciated and good to know that Trim is supported :-) Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted September 8, 2009 Corsair Employees Share Posted September 8, 2009 FW Version 1.0 already has TRIM, but it uses Indilinx own specific commands (wiper.exe). I think that you are asking about ATA TRIM command which is automatically initiated by a supporting OS. Example of a supporting OS would be Windows 7. Currently none of our drives have ATA TRIM support. Link to comment Share on other sites More sharing options...
ChrisJohn Posted September 9, 2009 Share Posted September 9, 2009 Now I am even more confused! Microsoft states: "In Windows 7, if an SSD reports it supports the Trim attribute of the ATA protocol’s Data Set Management command, the NTFS file system will request the ATA driver to issue the new operation to the device when files are deleted and it is safe to erase the SSD pages backing the files." * What other attribute is CrystalDiskInfo seeing when it flags up that the Extreme disks support TRIM if not the ATA? * http://blogs.msdn.com/e7/archive/2009/05/05/support-and-q-a-for-solid-state-drives-and.aspx Link to comment Share on other sites More sharing options...
Davyc Posted September 9, 2009 Author Share Posted September 9, 2009 I think I get what Ram Guy is pointing towards - in as much that TRIM will be reported as being supported, but only at a controller level (i.e. using the Indilinx Wiper). The actual ATA command as supported by Windows 7 is not currently active in the current firmware. Windows 7 will activate TRIM if it detects an SSD but even if operating within the OS it does not mean that it will operate within the SSD until the firmware supports that command set at the ATA level. If I'm reading this correctly then it all makes sense :-) Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted September 9, 2009 Corsair Employees Share Posted September 9, 2009 I am sorry I cannot confirm or deny this ATM and until the release of Windows 7 there is not much more U can say sorry! Link to comment Share on other sites More sharing options...
Davyc Posted September 9, 2009 Author Share Posted September 9, 2009 I am sorry I cannot confirm or deny this ATM and until the release of Windows 7 there is not much more U can say sorry! Understand - NDA's still in effect ...... wonder if Microsoft is associated with the CIA lol Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted September 11, 2009 Corsair Employees Share Posted September 11, 2009 I am sorry I cannot confirm or deny anything (SCHULTZ) when it come to Microsoft! :roll: Once its officially released there will be more information available. From what I understand reading between the lines Microsoft and the SSD Manufacturers have slightly different interpretations of the spec. and I think that is what most are working to resolve.
