SSD transfer speed

[realV00]

I've made a few storage purchases where the promised read/write speed benefit is rarely realized.

With the Samsung 960 evo/pro about to be released, and promising big speed increases, could you help clarify...

The speed of all writes to the 960 will depend critically on the read speed of the device being read (and its connection method to the motherboard) ?
So, if I am transferring from a slower device e.g. sata3 HDD to a 960 then the maximum possible speed will be the max read speed of the sata3 HDD ?

Similarly for reads from the 960 - depends critically on the write speed and connection type of the second device ?

If big benefits are seen when doing more than one operation at a time, is there software / a way to absolutely guarantee that the max number of files possible are being written to / read from the 960 e.g. does Teracopy guarantee to do this if I was to transfer multiple files to the 960?

Hey there, realV00.

You are correct. The faster drive's performance will be bottlenecked by the HDD's transfer speed, since it's a lot slower than that of a SATA SSD, not to mentioned a NVMe SSD, which is a lot faster. This goes both ways so, yes, the transfer speed (regardless of which drive is the destination drive) will be determined by the HDD's speeds.

As for your other question, there are different programs, which are said to optimize transfer speed and ensure file integrity, but unfortunately, as an official Western Digital representative, I can't really recommend a product/device, which is not under the WD brand. But I'm sure that someone from the community will be more than willing to help you with this.

Hope that helps.

Yes, you are correct.
Think of it like this:
You have a fire hose capable of 1000 gallons per hour (SSD), and a garden hose(HDD) capable of 10.

No matter how big that firehose is, you're still trying to feed it from the garden hose.

I wouldn't expend any brainpower on trying to find some magical software. You're still dealing with the read/write speed of the garden hose HDD.

Thanks folks for clarifying
