推 WARgame723 : 這顆ssd會回傳使用者資料嗎?
推 Bob9154 : 自動雲端備份
推 ltyintw : 如果他64層裡面有16層是用純硬體佈線來實做資料回傳ip的話,可以
如果這些言論是在FB之類的網路上出現很正常,但如果是電蝦版出現,那我覺得有些事
情該好好解釋一下才行。
來談談硬體跟ic的設計吧...
事實是,在超大型積體電路上的設計不是這麼簡單,也絕對不是短短兩三年就能研發出
一個穩定且不耗電的IC電路。
會這麼說是因為目前現存的主流晶片,幾乎都是超過十年以上的公司或團隊(這個很重
要)在設計、開發的,
在現在的市場環境,對很多性能上的問題是相當挑剔的,耗電量之外,發熱、延遲、負
載等都要考慮進去,才會是一個好產品。
如果一個手機加了一個會自動上傳資料的網路晶片(華為就是最常被嘴的),你可以想
像一下它的耗電量會變得多驚人,更不用說它吃得網路有多可怕,這種又熱又耗電,又
吃掉你一堆網路流量的東西你會用嗎?
這種你根本不會用得的東西,他幹嘛賣,想想就知道了。
說完手機來說SSD
一樣的道理,消費者是非常挑剔的,
每顆SSD都有他的讀寫次數,先不談不合邏輯的原理(晚點再說原因),增加一個網路晶
片要減少的壽命,連二手SSD壽命都不到的全新64層SSD,你會想買嗎?
講完壽命再來講原理
電腦的分工現在非常細了,每個事情只要夠大夠重要,
要求效率跟延遲的性能越高的東西,基本上都會有獨立的晶片在處理。
電腦中常見的網路卡有螃蟹卡、Intel晶片跟killer晶片等等幾種,
各位如果有興趣,可以看一下這些晶片做得多大顆,
再來想像一下塞在SSD裡面多複雜,
這種線路你請任何人來設計都不會有人想做的。
再來說到更實際的面向,
真正硬體實作網路封包傳輸的電路,都是旁邊直接做接頭連接RJ45接頭,或是光纖之類
的輸出入孔的,
因此,可以做到能在SSD裡面直接穿過主機板、穿過網路晶片,直接靠RJ45傳資料的晶片
根本不存在,
有也是SSD本來就直接督RJ45下去才對(幹話)
細節我就不講了,網路概論什麼握手原則這個有空可以去看一下...至少知道一下傳封包
的前提是什麼再說。
每個網路傳輸都有它的機制,向前面這個就是其中一種方式:
#1SjAY3AD (PC_Shopping)
無線有無線的,有線有有線的方式
講完消費者層面跟實際應用層面,再來就是合理層面了:
如果說我今天開發了一個能自動備份資料到網路的SSD,但是發現傳來的不是遊戲檔案,
就是A片A漫,試問,這種問題怎麼處理?
我的伺服器跟人力沒有能力處理這些垃圾呀.....
不相信的人我舉個例子好啦:
http://tinyurl.com/y4dup9hf
美國在賓拉登那邊發現一堆A片,為了怕他用A片藏什麼資料,或是在放A片的旁邊有什麼
重要資料,特別組了一個小組去看A片,
試問,我們平民何德何能可以讓阿共仔特別組人看我看了什麼A片?
最後最後我要講認真的
真正重要的資料都存在封閉式網路,
你只能用telnet之類的去跟它聯繫,這種給的權限一般都是資料只進不出或是根本不准
進出的.......
