不知道未来的服务器市场会不会迎来一次革命。
以前理解的闪存速度比硬盘快，但是它的读写寿命应该比硬盘低。不知道百度用得闪存是不是有了重大改进。

应该是固态盘吧？

百度第一个吃螃蟹，真是有胆有钱！

关于闪存读写寿命的问题，有很多牛人整天都在研究一些类似于算法的东西，原理似乎是在闪存上加一层规则，是存储数据的时候按照规则来，这样可以把闪存的寿命提到到几百甚至上千倍。
不知道百度是不是在这方面取得了突破。

提高闪存读取寿命的算法，核心就是要让每块区域都能平均使用，这个和碎片处理算法有点类似吧，不过做起来可真不容易，估计要根据应用的类型来区别对待。 对经常大块存储数据的和小块大量数据的算法肯定不同。  百度在这块应该是有些心得了，不然也不干这么大规模地更换。

对应用系统来说，硬盘读写层面一直是瓶颈，为此要想很多办法来尽可能减少读写，真要换成闪存了话，应该能减少应用开发的难度。

淘汰下来的 硬盘能卖么？买点做群集。

s135.com，什么时候弄点 微型云计算的 东西啊？

估计不是吧～如果是搜索结果，估计数据都是读的。。如果要写，可能用一个特殊的机制，减少写的概率或者××。比如访问的这个结果的节点肯定动态改变的。
