Fifteen years ago buying a new computer was easy, magazines provided comparative tests of PCs for one's budget. Now typical magazine specs are not high enough for my needs:

I need a PC that can duplicate a 5 gb file in less than 10 seconds.

Where do I find comparative tests for PCs at this very high end?

...

Thanks, I was hoping to buy a computer that has been tested (meaning benchmarked) and compared to others in order to benefit from the effort of manufacturers/assemblers who also benchmark several different configurations before sending hardware to magazines - at least the winning ones probably do.

Where's a comparative test of computers using this or similar drives?

The only one that could do "5 gb file in less than 10 seconds = 0.5 GB / s" is the fastest SDD:

at least it was when the article was written, there may be a faster one. For servers using RAID and SAS, you can go higher, but I'm betting you want desktop solutions.

It's actually duplicate (read and write) a 5 Gbyte file in less than 10 s, ie 1 Gb/s. And one can't just plug an SSD drive to a computer and expect to get the full speed on any computer.

Crucially, I want the computer that is better than its competitors of the same price.

1 (Gb / s) = 128 MB / s

That would be any regular higher end HDD, you can find many HDD benchmarks online. For example:

Thanks, I know what a byte and a bit are, it says 5 Gbytes in my previous post. Not to mention 8 times less than 1 Gbytes/s would not be terribly high end.

Gb = gigabit
GB = gigabyte
Gbyte = gigabyte

at least to me.

Here is the previous post that says 5 Gbytes. It is post #6:

I keep spelling it out, but for some reason it does not get across. My posts are not being read.

Because you keep saying "Gbyte" in some places and "Gb" in others.

Gb = 1,000,000 bits
Gib = 1.048,576 bits
GB = 1,000,000 bytes
GiB = 1,048,576 bytes

That and transfer rates are usually given in Gb (bits) / sec, while file sizes are in GB (bytes). You can just use "octets" instead of "bytes" to avoid confusion.

I only wrote Gb once and that was before I began to spell it out for you over and over, getting ignored over and over.

At the risk of sounding patronizing, can I suggest that sales people have been ignoring this case convention of Gb versus GB since long before any of the people in LQ first came across a school lesson on bits versus bytes and multiples, while a search on google will confirm that the convention is still not universally accepted because different market segments and academic subject areas have different conventions, for example in some areas it's always assumed to be bits and multiples, in others it's always bytes and multiples. Common sense in this thread would immediately make it obvious that gb is short for gigabytes because 1. files are usually measured in megabytes or multiples 2. hard disk benchmarks are in megabytes/s 3. megabits would take us to the medium to low-level where there's plenty of magazines with comparative tests of PCs.

So, you will have to look up piece by piece the components you need to build a computer that is better than its competitors at the same price. So, find mobo, CPU, HDD, etc. reviews and assemble yourself the best of the best. I'm pretty sure, however, that a decent computer will be able to do that amount of bandwidth to the SSD, if you get that SSD. Also, I'm pretty sure 5 Gbyte / 10 s = 0.5 GB / s not 1 GB / s (and certainly not 1 Gb / s = 128 MB / s), so check your math too.

There are plenty of reviews around, just search for them. For example here's one for CPUs:
