Lenny_Nero, you’re arguing on a very subjective user preference. It is true that Raptor or SSD boots OS only few seconds faster than 7200RPM drive (in my case more than a minute faster) and thus some will argue that it’s not worth the $200 difference for Raptor or $700 difference for SSD.
This is also true for other subjects as well. The popular one in this site is DVD vs Blu-ray for instance. People are perfectly fine with their $60 DVD upconverter but there are people who is willing to spend few thousands more to get hidef although both will view the same action, same dialog and happy ending. I can say more example but I hope you get the idea that you can’t just ignore some small percentage of techie enthusiast.
As for your technical arguments that MLC is faster and last longer than SLC, it contradicts my understanding reading from some articles. If you check Ridata website, “their” MLC products (click here) are rated MTBF up to 1,000,000 and P/E (program/erase or write/erase) up to 1,000,000 times, meanwhile “their” SLC products (click here) are rated with MTBF up to 4,000,000 hrs and P/E up to 2,000,000 times.
Another document that I read (click here: Samsung_SLC_NAND_Flash_Advantage.pdf) stated the advantage of SLC over MLC:
[B]SLC NAND Flash Uses Less Energy[/B]
With only two states and one bit of data stored, SLC NAND Flashâ€™s Control Logic is able to conserve energy when managing the electrical charge during operations. [B]This is why during the program operation SLC NAND Flash is faster than MLC NAND Flash[/B]. Since MLC NAND Flash has four states, and two bits of data stored, it must expend more energy to manage the electrical charge during operations. Applying higher voltage to program MLC NAND Flash degrades its memory cell characteristics. And with smaller margins, the chances of an incorrect reading are higher. Plus, due to leakage and other effects, the logic level of the cell may change. MLC NAND Flash must compensate with enhanced EDC (Error Detection and correction).
[B]The SLC NAND Flash Performance Advantage[/B]
The Write Data Rate of SLC is three to six times faster that of MLC, as shown [please look at the table/chart in the doc]
