Please Guide me to buy sony New Z series.

I need you help to enlighten me with sony Z series. I got a series of question that I need to understand. Please help me out.

I need a laptop which is portable for me to do a little gaming and photoshop. so before getting this laptop I need some guidance.

1)Does Sony Z series provide a newer version of SSD that support TRIM? because I'm worry in longer use of SSD will be slowed?

2)Worth Getting SSD or better off with HHD?

4)Is the SSD drive changable in the future?

5)Are there a big difference between i5-520, i5-540 and i7-620? which is worth for the price?

6)Is i7-620 a quad core processor?

Please help me because I'm planning to get the right laptop with the best understanding.

Thank you in advance.

 

1: Yes, but with Sony-supplied drivers and set-up, TRIM does not work.

2: Impossible to say without knowing exactly how you're going to use the laptop, and what your personal economy is like. Even a general overview of how you're going to use it won't tell us. Overall, I think most people would be happier with an SSD solution, but some would be better served by a HD (or a combo of both).

3: Colorless green ideas sleep furiously

4: Yes, but not user changeable. The physical size and connectors are non-standard, so you would have to buy replacement drives from Sony and get a Sony repair center to do it (unless you are comfortable with an exacto knife and soldering iron).

5: Define "big". Most people would likely not notice much difference, especially not between the 540 and 620. But with very specific needs, it could be considered significant.

6: Only in Sony's marketing. The real CPU is dual core.

 

1) so are there cany solution that the SSD could be fixed prevent from slowing down in the long run?

2) so by means i7-620 is just a dual core? so there much no difference between i5-540 and i7-620 right? then i should go for cheaper i5 an worth the buck!

 

1) There is another huge thread about the SSDs, which should answer all of your questions. The slowdown doesn't appear to be too significant with these drives, and re-imaging or formatting & re-installing your OS every so often will help with this.

2) The i7 will be slightly faster, but the i5 will allow for better battery life. It's impossible to say what will be better for YOU. It totally depends on what you'll be doing with your notebook.

 

Hi, Bryan1988!

The value of the more expensive CPU is really up to you. Remember that the two different CPUs are actually identical silicon. In the Core i5-540, Intel just turns off 1/4th of the cache memory (from 4MB to 3MB), and sets the multipliers such that the resulting speed difference is just 0.266 GHz faster. Is that worth a price delta of $150 (in the USA)? Even as a performance freak, the convenience of getting a machine much more quickly and less expensively led to my selecting a Core i5 configuration. In the real world, most programs will show only small performance differences between the two models.

Cheers!
