SSD - low IOPS and low transrate of files from HDD to SSD.

[pigstriker]

Could someone help me understand why this is happening? I've enabled AHCI and have connected the ssd to a native sata 6g port. ANy help would be appreciated. Thanks!

Probably because your hard-disk can only deliver the 80-90 MB/second, doesn't matter how fast the SSD is...
You are copying FROM it, right ?

What about vice-versa? Will SSD be able to transfer files at a high rate? Also do you know what's going on with the low IOPS? Particularly the Random Read.

Faulty installation? -



Step 1: Prepare Installation

Please ensure your SSD remains in the anti-static carrier until installation to prevent damage caused by static electricity.
Handle the SSD with care and avoid touching the SATA connectors.
Ensure your motherboard has the latest BIOS revision installed (confirm with the motherboard manufacture for the latest updates).
Ensure your SATA controller is operating in AHCI mode.

Step 2: Install SSD

Power off the system and disconnect all power cables.
Remove the system’s outer panel (refer to your system’s user manual).
If your system provides 2.5-inch drive bays, there is no need for a 3.5-inch adapter bracket.
If your system does not provide 2.5-inch drive bays, you will need to mount the SSD onto the 2.5-inch to 3.5-inch adapter bracket with the mounting screws provided.
Note: An adapter bracket is provided with select SSD models.
Install the SSD into an available drive bay.
Connect one end of the SATA data cable and power connector to the SATA connectors on your motherboard and the remaining end to your SSD.
Note: SATA connectors are keyed to prevent improper installation.
Re-install the outer panel and power on your system. The SSD should now be recognized by the system.

Transfer between two devices can only be as fast as the slowest component, it doesn't matter the direction.

IOPs are not slow, run the benchmark on your HDD for a comparison.

Same speed for read and write only means your controller is saturated, not the flash chips themselves. Small random IOPs from RAM will always do this unless the flash is slower than the controller.

I fixed it by upgrading the bios.
