I formatted this brand new Extreme 120GB SSD which came factory direct with the R211 firmware using Windows 7 selecting 4096 bytes for allocation size and unchecking “Quick Format”. I just bought four of these SSDs to speed up four of my slower systems. It would be nice if the two running the nVidia NForce590 chipset would work like the two running the ICH7-R chipset.
Note: all my systems run on XP Pro 32Bit and I only use a laptop that has Windows 7 to format the SSD’s attached by USB.
On my Dell XPS 700 with the nVidia NForce590 chipset, running a Intel E6300 CPU and 4GB RAM it gets no better than 111MB/s write and 138MB/s read with ATTO. BIOS is the latest.
Thinking that maybe I buggered something up during formatting I then placed that same drive into a USB3 desktop hard drive dock and got 144MB/s write and 178MB/s read using ATTO.
I then placed it in a different system running an Intel MoBo with a ICH7-R controller (SATA2), D840 CPU and 4GB RAM and got 255MB/s write and 247MB/s read again using ATTO.
Finally I placed it on yet another system using an ASUS U3S6 PCIe 4x card that claims SATA3 on a Marvell controller and got 181MB/s write and 411MB/s read with ATTO.
The nVidia NForce590 chipset is suppose to be SATA2 but I am seein what looks like SATA1 speeds. Is there something that I’m missing here or is this a known problem with this chipset?
