人生中的第一顆固態硬碟 The first SSD in my life



由於英文寫作的能力實在有待加強,所以以後會盡量練習自己的英文寫作,如果有時間的話,盡量會以中英文介紹,藉此機會練習英文

Because the ability of English writing is not good,I have to practice it if I have time in the future,I will do my best to introduce both in Chinese and English.


首先非常的簡短以通俗易懂的說法來介紹固態硬碟吧,從2008 Apple WWDC 會場裡,大家看著賈伯斯從牛皮紙袋拿出的MacBook Air那一刻起,一直到現在的Wintel聯盟出的 Ultra book,很多的筆電都慢慢捨棄了傳統硬碟而轉投固態硬碟,究竟固態硬碟到底在貴什麼?憑什麼容量小又賣的比別人貴這麼多!?

Let me introduce SSD in a easy way first,it's starting from the WWDC in 2008 when Steve Jobs took out MacBook Air until Ultra book which publish from Wintel.There's more and more PC company give up pre-installing a HDD on it.That's see why the storage space of SSD is smaller but the price is  higher.







我已經觀望非常非常久了,之前好像有說過如果120g SATA III 降到3000內我就買,但後來又卻步了,原因有兩個,一個是以目前的情勢來說,我..不負責的認為,SSD的價錢是一年跌一半,是什麼意思呢?可以說成去年120g的SATA III也許要賣6000多,但今年這時候就掉到了3000,不過這只是我這一年的觀察,而且每家廠商也有不同的經營策略,所以還是那句話,有需要而且能真的發揮它的價值,就不要吝嗇吧!第二是後來我才知道現在市面上大部分廠商做的速度非常快的SSD都是採用sandforce晶片,這也是另一個讓我在觀望的地方,並不是說sandforce晶片不好,只是想買的人可以做功課了解一下sandforce和Marvell晶片的好壞差異再買也不遲

I have already observe the SSD 120g SATA III for a long time,and I will buy one if the price downward under 3000NT.There's two reasons why I haven't buy it because I roughly guess the price will cheaper to half next year.For instance,if the SATA III 120g sell 6000NT this year,then the price next year will probably go 3000NT and so on(but it's still my thinking) .If you do really need that and use it as it's really worth,don't hesitate
to get one. Another thing I care about is,most company use the sandforce controller in newest SSD,it's worth to wait and see a while.It's not mean Marvell controller definitely better than sandforce controller,it's not too late if you can do a reaserch before purchase .


這個故事是這樣開始的,當時想著便利性,就先帶著姐姐於2007年中在澳洲買的Acer aspire 5573A2 WXMi notebook 來澳洲,想不到這台電腦的硬碟問題越來越嚴重,一開始只是偶爾當機後來我索性就重灌,也試過還原,還用HDD regenerator 掃壞軌,雖然一開始都有效,但是你也知道的,壞軌就算能靠軟體修復,但也只是治標不治本,硬體壞軌壞了就是壞了,如果一直拖下去,雪球只會越滾越大,最終還是會造成無法彌補的損失,所以平常的資料備份真的真的是很重要阿,千萬不要省小錢而損失了大錢,因為就算是使用HDD regenerator,也只能撐一下,也許這區的壞軌修好,但用幾天或幾週,那邊又會出現壞軌,修不完的,甚至壞軌越來越多都有可能,還好裡面的資料有備份出來,話說小硬碟的好處就是,資料一下就備份完了!哈哈(苦笑)

This story is begun from my sister's computer(Acer aspire 5573A2 WXMi notebook) bought in the middle of 2007 in Australia,the problem of bad sectors is bigger day by day.I have tried many ways to fix it including HDD regenerator,but maybe this section is OK today and another section failed next few day e.t.c. although the software can fix bad sector,it's still in a risk to use the drive until the whole drive failed.It is important to backup your data in specific time,because if the bad sector is in physical area,the problem will increase more and more,that's why we need to backup data ASAP.I am glad to backup my data before the HDD is more and more weaken.Because the storage  is small that I can backup my data in short time.

現在如果要買舊筆電用的硬碟真的非常"監介"因為我拆開來看雖然是SATA沒錯,但我心知肚明,知道他了不起就是SATA I,不可能給你到II,所以我就上台灣的y拍也好,r拍也好,甚至是澳洲的e拍,發現到,真的是尷尬的不得了,要買個80~320的硬碟,全新的價錢都要一千五吧?到兩千多都有,二手的雖然便宜,大概是1000多可以買到80g或160g,但重點是...二手硬碟我真的覺得運氣成分很大...何況又要運來運去,我會怕啦,後來,不知道哪來的想法,我就直接衝固態硬碟了,我的想法是,先給這台筆電用,反正這台筆電最多我也只會用個3年多吧,先用固態硬碟擋一擋,而我這台筆電也就是上網打paper和寫coding,盡量保持硬碟和系統的乾淨,這樣穩穩用應該三年後還是可以拆下來裝我家的舊電腦的,於是打著這樣算盤的我就在e拍買了這個OCZ SATAII 的SSD,以現在的技術來看,應該很多人會覺得不該買這顆的,但是我想在價錢方面,我想應該是還好啦,反正也就是比我要買的hdd多個500~1000,而速度又是快個2倍半,所以就買下啦

It's hard to make a decision to buy HDD or SSD .I tear and try to figure out the port is SATAI,so I search some bid websites then realized that buying a new HDD(80g~320g) is not as worth as I expect,maybe the price of second hand HDD is good but it's a risk to use second hand electronic product especially HDD.Finally I decide to buy SSD for further view.My opinion is ,I can use this SSD as my notebook's
operation hard drive and I just use it to do the heavy free work like browsing website , coding and doing paper.If I can leave my system and ssd as clear as possible,I think it also can be useful when this computer is out of work.I know this SSD is out of style in this time,and someone might think it's not worth to buy,but I still think it's worth to try and think about it.so I just bid it on ebay.



來個一張正面圖,真的是有點像玩具的樣子
It's looks like a toy



再來一張是背面,怎麼背面比起前面有質感太多了!
But the other side is much more quality than toping!



最後一張來個世代交替的圖片吧!
the last photo show the previous and next gen of hard drive


下面是裝到電腦上的硬體測試圖片,當然,這些數據的東西還是僅參考就好,但是有很多東西真的是親自體驗過才知道
here's some photos of benchmark,it's for reference only and the rest part should experience yourself.

買這顆硬碟唯一的遺憾是,我買了才知道我的主機板不能開AHCI,開了AHCI才真正的發輝SATA的技術的價值所在,由於不能開AHCI,所以理所當然我的Win7不能用到Trim的技術,但是呢,算了吧,目前的開機速度雖然不像一般接在SATAII的開機那樣飛快,但是比起之前的5400轉,我已經滿意很多啦!
Unfortunately,I found that my motherboard is not suport AHCI,so it can't be as worth as a real SATA,and the "Trim" function in Win7 can't enable either.but anyway,I am satisfied at my new SSD although it's not as quickly as in SATAII,at least still better than previous HDD(5400 rpm)

    話說SSD的讀寫速度不是可以到幾百MB的嗎?

  3. 我買的這顆是SATA II的,所以理論值最高的速度就是讀寫到300mb,但是我是接在SATA I且不支援AHCI的主機板上,那麼最高的速度就會被限制在Parallel ATA(比較耳熟能詳的是名稱是ide),而ide理想速度就是在UDMA5(100)或6(133)的速度了,改天等我有另一顆2.5吋的接到這台筆電,我就能把這個SSD接到我的桌上型了,先委屈它一下,到時候在來分享一下速度 :D
