Subject: Re: Solid State Disk to boost Mathematica performance

OS is Windows 8- 64bits.

Other HW info:

Chipset H67

Intel Core i7 2600/ 3,4 GHz (four cores - 8 threads)

Frontal bus DMI transfer rates: 2.5 GT/s

The technical info for transfer rates supplied by specialists (Intel does

not provide much information about its chipset, as far as I know) is a bit

confusing. I am posting this info from third parties in case it is of any

use for others.

These third parties say:

_________________________

"So the i7 is 2.66GHz clock speed, 4.8 GT/s per second, and uses the QPI

interface which transfers up to 25.6 GB/s of data.

While the i5 has the same 2.66 GHz clock speed, it transfers 2.5 GT/s and

the DMI interface can handle less than half the data across the motherboard.

Amazingly, the 2.66GHz 2.5GTs DMI i5 is considered noticeably faster than

the top of the line Core 2 Quad 9650 which has 12MB cache, 3.0GHz clock

speed and a 1333 bus speed (FSB)."

Which suggests that my Intel Core i7 2600/ 3,4 GHz (four cores - 8 threads)

would support the 6GB.

Thanks very much to everybody. Your remarks are going to be useful.

Likely replacing your hard drive with a SSD will have no effect on the

performance of Mathematica. Where it should improve performance is cases

where Mathematica needs to read/write data to the hard drive/SSD. I would

guess for most of what you do Mathematica performance it bound by CPU and

memory rather than I/O.

Also, you should pay attention to other parts of your system.

For example, you cannot take advantage of the greater though put of a SSD

that supports transfer rates of 6Gb/s if your system bus is limited to

transfer rates of say 3Gb/s.
