Raid 0 Transfer Speeds Dieing?

Go to solution Solved by A_Wild_SkyBear,

Hundreds/Thousands of smaller files will be a LOT LOT LOT slower than transferring bigger files at once.

The drive cant ramp up its speeds very well with many tiny files.

/you could zip them with minimal compression and that may be faster as a single transfer with enough filesize that the drive actually hits faster speeds.

I'm thinking that's the issue but usually when I back up photos to this exact USB its never this slow. Seems strange. I know the speed should be capped but not keep sloping down after a constant, seems weird to me

I have a Raid 0 boot drive comprised of 2 Samsung 840 Evo 120GB SSD's in Raid 0 and Im trying to transfer a folder of pictures to a USB3 stick I have. I have plugged the USB into a USB3 header on the motherboard and IM moving about a GB of files. The transfer started out at around 5MB per second which is VERY slow compared to all the other times ive transferred. But then the speed slows down to about 30KB  second like a drop off and then picks up for a second only to repeat. This has taken me about 17minutes so far to transfer about 60MB, can anyone help?

Bottleneck on that USB. Have you tried moving the files to a non-Raid drive first?

Maximums - Asus Z97-K /w i5 4690 Bclk @106.9Mhz * x39 = 4.17Ghz, 8GB of 2600Mhz DDR3,.. Gigabyte GTX970 G1-Gaming @ 1550Mhz

No doubt tried.....but Try other usb ports maybe, or try the same drive on other machines and test its speeds...

Other than that... new drive?
