A SSD cache is used to store, in non-volatile memory, the programs and files you use the most often. When you run them, the computer checks the SSD first to see if the files are there. If they are, the HDD isn't used. Only when there is new data that the SSD does not have that the system accesses the HDD.
Seagate Momentus XT does just that, pairing a 500GB / 750GB HDD with 4GB / 8GB of SSD cache. A small SSD as a cache drive is a logical extension to the idea.
It makes commonly used programs load very fast and allows bootup times akin to a computer with just a SSD for storage. The downsides being 1) you have to "train" the computer for it to figure out what you use all the time, and 2) it might be fast
er than HDDs alone, but it's still no substitute to a SSD.

This thread isn't a comparison between X number of devices, Sahee, it's basically an Astroturfed ghost-written review for the ZBP and a Kanye West rap battle against the MBPR.
To recap:
- You want people to agree with you that the ZBP is a better value than the MBPR simply based on pricing. On a Mac-centric forum. With zero consideration of everything else without a price tag.
If you are cost-conscious, don't buy Apple, problem solved. No need for stupid threads like this trying to reason - and fail hard at it - why a pot is better than an apartment hot water boiler unit.
- The MBPR is heavier and larger than the ZBP. So what? It has far more processing power on tap that makes many gaming laptops feel outdated.
- The good news about the GT 620M is it's faster than Intel HD4000. The bad news about the GT 620M is it's faster than Intel HD4000. In other words, it's crap.
- The ZBP in the configuration you described does not include a SSD. A HDD + SSD cache is all about
meeting Intel's minimum requirements to use the Ultrabook(TM) moniker, and is at best faster than a HDD. This setup is still nowhere as fast AND responsive as a SSD.
- Intel ULV dual-core Ivy Bridge vs Intel standard-voltage quad-core Ivy Bridge. Furthermore, if you insist on using its integrated GPU, the ULV cannot run its GPU on Turbo all the time due to thermal restrictions.
- Up to 10GB RAM (unconfirmed) vs 8GB RAM minimum and 16GB RAM max.
- The ZBP screen is slightly better than the MBPR's, but it's nothing to write home about. Also 13" 1080p is so last year's tech - it's already possible to cram a 1600v resolution into a sub-7" LCD screen. ASUS even has a tablet smaller than the ZBP yet uses a 1200v IPS screen, with oodles more battery life to match.
My review is not bias-riddled
Overstatement of the week.
It is full of bias from the get-go and it only goes downhill from there.
