The SATA 2 ports are controlled by the JMicron JMB363 chipset controller. This is shown under device manager in windows XP under the heading of SCSI / RAID controllers. The problem is when I go to use the Samsung Magician software (essential under XP for garbage deletion etc since XP has no Trim support)a message says "no Samsung SSD found" The only way I have got this to work is by replacing the JMicron device with a standard IDE controller and it is then fully recognised by the magician software. Unfortunately I have been unable to replace it with any AHCI controller. The other SATA ports on my motherboard are only SATA 1 and are controlled by a NVIDIA nForce3 250 south bridge chipset . Again Magician won't recognise the drive if I connect it to the NVIDIA SATA ports and again I have to remove the NVIDIA driver and replace them with a standard IDE controller. I want to know why the drive magician software won't work with the correct controllers on my motherboard? As a result I have had to resort to standard IDE controllers. As an experiment I got another drive and installed windows 7 on it. In windows 7 the SATA 2 ports controlled by the JMicron controller are listed under device manager as Standard AHCI 1.0 Serial ATA Controller and as such the drive is recognised by the magician software. I tried to copy the Standard AHCI 1.0 Serial ATA Controller driver from windows 7 over to my XP install, however when I try to replace the JMicron driver on my XP install with the standard ATI driver from windows 7 I just get the blue screen of death on reboot. Does anyone know if there are any standard AHCI Microsoft controller drivers that I can replace the JMicron with in XP (like in windows 7)?
My other problem is no matter what I do the drive is vastly underperforming. No matter if I use the JMicron controller, Standard IDE (in XP), or the Standard AHCI 1.0 Serial ATA Controller in Windows 7 I only get performance for read and write of about 100 Mb/S. This is a long way behind the SATA 2 speed expected. How can I improve this?
My main priority is to get this working properly in Xp (although it would be nice to see it working under any operating system) as I have some very expensive commercial hardware that only works in XP and I would really benefit from the speed that my SSD could yield in that environment.
the issue right now is most ssd and ssd software is written for intel mb chipsets.
all i can say is try the newest drivers for your mb if that does not work look into putting your ssd on a adaptec or other newer 3 party sata controller. ftp://driver.jmicron.com.tw/SATA_Controller/Windows/JMB...
I already tried the newest drivers but same issue. Do you know any SSD drives and software for them that work well on non intel chipsets?
If I got a 3rd party sata controller would that relaly be quicker than the 100 mbs I already get? As it woud have to be PCI as I don't have PCI express on the board. What sort of results would I get with a PCI SATA controller?
TRIM is not the issue as Samsung and Intel provide manual TRIM programs under XP for their drives. AS I say it is the controllers on the motherboard that are the problem as the the speed issue is still the same in windows 7
