如何分辨NAND FLASH 等級不同的差異!? SSD效能壽命關鍵!! - 小P的SSD秘密實驗室

2012年4月11日 9:08

HI~~大家好，我是小P

小P用兩週的篇幅好不容易將SSD的Controller介紹完畢了，接下來要講的是比較沒有人注意到的小細節---NAND FLASH顆粒。

大家有沒有想過有些SSD品牌不同，Controller選擇同一品牌，但是價格卻差了一大截？難道是該公司特別佛心嗎？當然不是的，秘密就在於「NAND FLASH」，這個通常不會寫在規格表的另一個關鍵因素。

而NAND FLASH在顆粒上有「同步顆粒」（synchronous NAND flash）與「非同步顆粒」（asynchronous NAND flash）的差別，簡單的來說在大量生產NAND flash時等級較高的就是「同步顆粒」，而在品管階段達不到同步顆粒的效能等級的NAND FLASH就被歸類為「非同步顆粒」，一般來說非同步顆粒的效能與壽命都比同步顆粒的NAND FLASH差。

而您買的SSD到底使用的是同步或非同步顆粒，說實在話除非你將SSD拆開查詢批號，否則永遠都不會知道，有的製造商甚至會將NAND FLASH上面的批號打磨掉（除非像Plextor敢強調是使用同步顆粒，http://www.chiphell.com/thread-346363-1-1.html 的中後段有部分SSD所採用的顆粒批號與種類給大家參考）。

既然「非同步顆粒」效能比較差，那為什麼有的廠商會使用非同步顆粒來製造SSD呢？想當然爾，因為非同步顆粒的成本較低，但在搭配部分Controller之下，如果不做詳細測試看不出差別的，以下圖來說，這是兩款都使用SandForce SF2281控制器，但搭載同步與不同步顆粒的SSD。

▲在規格上幾乎看不出差異。

而且跑ATTO DISK BENCHMARK時也沒有很明顯差別：

 

但是只要用HD Tune Pro與CrystalDiskMark測試讀寫效能馬上高低立見，這是因為這兩個軟體都不能透過資料壓縮的方式進行測試，所以品質較差的非同步顆粒效能就被比了下去（尤其是CDM中的連續存取與512K這兩個區段）。

 

 

其他在Windows的各項運作表現上同步顆粒的表現也會好上許多（如軟體讀取、遊戲、開機….）：

 

 

 

最後除了NAND FLASH顆粒等級的不同以外，最後影響效能的就是資料傳輸介面，目前有三種：EDO、ONFI、Toggle Mode。

EDO（extended data output）：這個規格最舊，最大讀取速度只有40MB/s。

ONFI（Open NAND Flash Interface）：此技術的優點就是非同步顆粒也可以使用，最新的ONFI 2.2的雙通道顆粒輸入200MB/s，SandForce採用的就是此技術。

Toggle Mode：採用類似DRAM傳輸的方式，寫入速度達320MB/s，仍然高過ONFI的雙通道顆粒寫入速度，這也是Marvell採用的技術。

但是不管ONFI或Toggle Mode哪一個傳輸介面，目前8通道讀取的SSD，都已接近SATA2/SATA3介面傳輸速度的上限，而連續寫入是看使用Flash品質，Flash寫不進去這麼快，Controller再快也是枉然。所以聰明的您應該知道應該要挑選那一個傳輸介面與NAND FLASH顆粒的SSD了吧？（給您點小提示，Plextor SSD就是採用Toggle Mode技術與同步顆粒NAND FLASH）
