发帖数: 25662 | 17 as for real world performance, there is no difference between Agility and
Vertex from my research. There maybe some long term advantages on Vertex's
side because of its higher IOP rate.
I jumped newegg Vertex2 120G but got canceled.
MC is not selling any Vertex line...
If you measure in terms of Gb/$, 90G 120G 60G are approx. the same.
32G is too small for me even as a system drive. I prefer at least 60G.
Idealy, I would like around $100 for Vertex 2 60G as sys drive and buy one

Vertex 2 has higher IOPS. ppl say that means potentially longer life. I
would expect(but thats not the case based on reviews) a better random 4k
write/read performance, which is more important than sequencial r/w for a
sys drive imho. Based on my research, ppl like vertex better than agility if
they are priced the same or almost the same. |

http://iopscience.iop.org/page/Nobel
有人说我他就是先切个碳薄片，然后所有文章都是描述这个薄片的各种性能的
。只在技术上有贡献，没理论，没有啥好东西，诺贝尔奖为啥给他。我个人认为他首先
做出这个薄片就不容易。这东西是最薄东西里最硬的，茫茫的材料世界，人家找到这个
还是需要理论指导方向的。另外他论证出了那么多好的物理property，让这个材料的应
用价值变得太大了，是革命性的。这跟光纤之父获得诺贝尔一个道理。现在的风向显示
物理上的研究能获奖不是靠理论突破了，而是其应用价值。 |

New Superconductors Propel Chinese Physicists to Forefront
Adrian Cho
Hai-Hu Wen went to work as soon as he heard the news. In late February, the
44-year-old physicist at the Institute of Physics (IOP) at the Chinese
Academy of Sciences in Beijing learned from a colleague that researchers in
Japan had discovered a new superconductor that carried electricity without
resistance at a relatively balmy temperature of 26 kelvin. He immediately

俺也来说说BB cream
这个东西说的人太多了，但是每个人的体会不一样，我来说一下我的使用感觉。
首先说它的性质，我以为应该定位为有遮瑕作用的隔离霜。不是粉底也不是遮瑕霜，因
为它是不加色料不分色号的。至于为什么遮瑕我不甚了了。我的皮肤很干，用粉底要起
皮，看起来很皱，换了无数种产品都一样。可是用BB cream 则没事，只要之前涂过保
湿霜，经过一个白天摸上去都是潮湿的，看起来非常健康。我本来毛孔就不大，肤色均
匀，只有小小雀斑，所以遮瑕的诉求不高，BB cream恰好满足我对自然效果的追求。有
的品种太厚重了，我不喜欢。跟我情况类似的人，推荐使用Hanskin的最基本款（白色
包装叫magic没防晒的），极为细致，涂上根本看不出有东西，可是显得皮肤非常好。
当然啦本人不是非常白，我知道很多亚洲女人白得像僵尸，那样的话可能Hanskin有款
黑色包装的super magic不错。如果是比较黝黑的，我用过一种IOPE的，价格有点贵，
但是颜色略深，效果清透自然，品牌是很好的（大公司而且产品以护肤品为主）。其实
我们黄种人年轻时白，衰老后黄，所以略往白里涂 |

发帖数: 1309 | 46 现在SSD肯定是要冒风险的，SF已经是一个比较可靠的方案
不过总体还是Intel最好，它唯一的劣势就是初始态持续读写的数据没SF那么YY，其实
使用中真正需要比的是GC态QD1 4K IOPS，这点上只有C300强于G2，说SF比intel强其实
也没什么道理的

发帖数: 1309 | 47 They have the same control chip but vertex is better in 4k IOPS.
Of course it could improve your system speed significantly. The problem is
that they sound luxurious for netbooks. Anyway, it depends on you. |

t*****s
发帖数: 1309 | 48 这个说法不太正确，ATTO和HD TUNE一样测试的是主控能力，和NAND速率无关，所以能
达到所谓的275/285
CDI才能测试真正的磁盘能力，这个持续读写并不奇怪，比较奇怪的是QD1 4K的速度，
即使在GC态也应该有20/30,10附近太低了
可以用HD TUNE测一下4K IOPS看有没有8000 |
