剛從Amazon入手Sandisk Extreme II 480GB SSD, 慳了約$600.
SSD乃祖國制造, 盒內附有一個7mm轉9mm框架及說明書. 請看圖 -
測試開始:
(1) CrystalDiskMark
Seq. Read: 525 MB/s, Seq. Write: 486MB/s --- 不錯
4K read 31MB/s 普通, 但write有120MB/s很快
(2) AS SSD Benchmark
不過不失
(3) HD Tune
最高read有467MB/s, 平均403MB/s
(4) ATTO Disk Benchmark
平均有510MB/s --- 不錯
SSD平均約$5/GB --- OK.
此SSD會為CachecadePro 2.0作SSD caching用

唔同容量,冇乜可比性喎Samsung 1tb, Sandisk 480g, Plextor 256g
相對上,反而隻plextor好快,隻sandisk就差d喇

以Normal Mode計,暫時最快應該都仍然係Samsung 840 PRO

呢隻Sandisk Extreme II 480G用Crystal Disk Info睇唔睇到SSD既資料寫入量?
作者: kenn 時間: 2014-4-8 16:03
Sorry, I have connected this SSD to the raid card to activate the CachecadePro 2.0. So I could not check it with CrystalDiskInfo now. Perhaps later after I disconnect it from raid card.
Yet I had saved a screen shot of it in HDTune (see below) . Please note "F1" and "F2".

因已駁raid card作SSD Caching, 故開CrystalDiskInfo 6.1也看不到此SSD (除非將SSD caching disabled再駁回底板之sata port).

用1隻和用2隻 SSD 做 Caching,速度分別大唔大?

作者: kenn 時間: 2014-4-9 16:47

SSD caching之速度同SSD之size有關 --- 理論上SSD之速度亦不會太慢,亦相差不太遠。
SSD本身也有不同容量之DRAM作cache用途。
作者: idolclub 時間: 2014-4-9 23:27
2 x SSD RAID 0 CacheCade,Seq Read/Write速度大約比單隻SSD CacheCade高20~50%
