Drive Write Speeds

I have just installed a NAS and noticed some slow write speeds. So fired up HD tune and noticed some odd differences between drives.

Screenshots show the HD tune graphs. One of the 3TB drives I have is dog slow and erratic but shows healthy.  Other shots for the other drives to compare. Any ideas what maybe causing this?

BIOS is old also, could do with updating but the system runs fine. Worth the risk?

Also see device manager. I thought i might not have the AHCI drivers loaded correctly, does this suggest I do?

Think thats slow, My Os drive is a 40gig and hardly pulls off more then 25MB/s ;)

But ya you have one drive thier that seems to have problems.

here you go

I have actually removed one on the 3TB drives today one that seemed to be working OK with 2TB. The 2TB writes OK also. I swapped a couple of SATA cables and ports but to no avail. That one 3TB is a dog.

Had that happen to meny drives that got old my self, they don't 100% die but data speed on the drives in question dies as well some of the cheaps on the logic board heat up like mad, check with your finger when the drive is doing something if you can pick up on heat, if this is going on it means the logic bord is done as is the drive, time to back things up befor you can't anymore off that drive.

here you go

Which drive is currently used for the operating system?

The Speccy doesn't show any problems with any of the hdds.  The temperatures look good.  The only thing I believe you should consider is the fact that with the newer hdds of 2TB or 3TB the read time will be slower that with smaller or SSD drives.  I don't see anything worth being concerned about here.

The SSD for the OS. Did you see the attachment showing the hdtune results for the 3TB, its awful.

i did, 1MB/s HDD, my floppy drive can do better !

And a logic board chip heating up won't show up in any hardware monitor, you have to go for the finger test to pick up on that topic, chances are you have one chip that will be ripping hot.
