Samsung 830 64 gb is a lot slower than expected.

Hey all, I went through a major overhaul over the last week on my pc. With all the upgrade I finally got a motherboard that is sata3 6gb/s. I have had a samsung 830 64 gb ssd for about 3 months now and while it was running on my mATX sata2 board I was getting read speeds of 140-160 and write speeds of 120-130. Well the specs for this ssd states that it can get around 560 mb/s read and 160 write. The problem I am having is that the write speed now with the new motherboard is a lot higher than before but it is still no where close to what it is verified to put out. the last I ran it was 271 read and 157 write. The write is fine with me but it is half as slow as what is projected. I have changed the bios mode to ahci but there was another option on it that I didn't know. The motherboard is foxconn a9da-s. Here is a screen shot.

A couple things that come to mind: Double check there is no firmware update for your SSD (some models needed them to improve speed), and verify your bios is set to AHCI mode for this drive.

Also make sure indexing is turned off in Windows

How can you turn that off?

 

[mightymaxio]

Right click harddrive in my computer, then click properties, then the first box uncheck indexing

I’d suggest you go back to your user’s manual and confirm that the SSD’s settings are correct for the SATA 3 motherboard. Also, Samsung’s SSD Magician software, which comes standard with your drive, offers an auto-configuration function, which should be able to help you confirm that the system is configured correctly.
