想問下intel x-25m vs corsair f60~~

想問下intel x-25m好係邊?官方標示速度係R:180/W:170
但係好多牌子都已經快過intel而且價錢都係咁上下~~但點解都仲有人推薦intel?

R:180/W:170 係錯誤數據.

SSD唔係睇sustained read / write做效能標準...
要做到SSD咁既sustained read / write 普通兩三隻HDD行RAID 0 已經有
而最主要既優勢係起random access time度 即process 細file所需時間俾傳統HDD快好多倍.
Intel本身呢方面效能做得好, 而且有Toolbox做support所以多人推薦唔出奇.
另外值得一提既係Intel X25-M 本身sustained write表面上係比其他SSD 特別係Sanforce 1200 series controller based 弱, 但係random write度就絕對唔輸蝕, 所以整體性能兩者唔會差好遠.

Random Write先輸得多...

OWC Mercury Extreme 50大約係Vertex 2E 60G水平,都快過Intel x25m G2 80G

如果Vertex 2E 90G 對 Intel x25m G2 80G...Vertex 2E 快得仲多...

x25m Write邊有170...........得100MBps

邊度見到快好多? 我睇唔到..
如果你睇2MB Write既話Intel 差係因為受制於本身sustained write speed...
睇4k random write兩者差唔多
而且你用SF1500 Controller 黎比較 唔多公平...

Vertex 2係SF1200,不過用SF1500 firmware

如果Vertex 2E 90G 對 Intel x25m G2 80G...Vertex 2E 快得仲多...

我聽講(唔記得左source)
intel SSD用起黎效能好d系因為佢個controller系parallel write既情況下做得比其他controller好,而好似話d speed test系無test到同時parallel write既效能
有錯請插

回復 6# sunderstan
V2 個寫入速度的確快過 G2 好多, 唔係個個已經一窩蜂買晒 Intel, 做埋 SSD 獨市生意

好多test都support command queuing,e.g. IOmeter, CDM, AS SSD,Intel同SandForce都suggest user用AHCI
