作者 capri75 (capri) 看板 Storage_Zone 標題 [測試] Ramdisk大亂鬥:Buffalo/Dataram/ImDisk/QSoft/VSuite/SuperS 時間 Fri Feb 18 00:09:44 2011 ─────────────────────────────────────── 既然要做Ramdisk測試 那就乾脆多做幾間的比較 來個大亂鬥 XD 先把心得說在前面 數據看起來很怪 Dataram狂輸Vsuite 加上ImDisk的部分寫入異常低落 我覺得奇怪的部分都有重複測過至少三次 變化不大 這次測試感覺用處不大 但想說都已經花時間測完了 還是PO上來給大家鞭一鞭 不知道到底哪裡出了問題... =============================== 測試環境 i3-530 DDR3-1333 12G(威剛4G*3) ASrock H55M-GE Win7 x64 (剛重灌完的狀態 僅安裝驅動程式與win更新 關UAC) =============================== 測試對象 SuperSpeed RamDisk Plus 11.5.390 x64 (15天試用版) http://www.superspeed.com/desktop/ramdisk.php ImDisk Virtual Disk Driver 1.4.0 (freeware) http://www.ltr-data.se/opencode.html/#ImDisk BUFFALO RAMDISK ユーティリティー　Ver.3.0.0.0 (freeware) http://buffalo.jp/download/driver/memory/ramdisk.html Dataram RAMdisk V3.5.130R17 (4G以內免費) http://memory.dataram.com/products-and-services/software/ramdisk QSsoft RAMDisk "Enterprise" 5.3.2.12 (試用版) http://members.fortunecity.com/ramdisk/RAMDisk/ramdiskent.htm (網頁似乎故障 我稍早下載時還是正常的) VSuite Ramdisk 服务器版 V4.6.7531.1240 (15天試用版) http://www.romexsoftware.com/zh-cn/index.html ================================ 測試設定 http://dl.dropbox.com/u/8246392/Ramdisk/Status%20of%206%20ramdisks.png http://dl.dropbox.com/u/8246392/Ramdisk/Status%20of%206%20ramdisks_2.png http://dl.dropbox.com/u/8246392/Ramdisk/CHKDSK%20of%206%20ramdisks.png 六個ramdisk 全都從官方網站下載並安裝 1G容量 FAT32格式 4096位元組配置單位 沒有放置任何檔案或其他系統設定(如pagefile 系統變數或IE暫存等) 以ATTO Disk Benchmark v2.46與Crystal Disk Mark 3.0.1 x64兩個軟體測試 (同一時間內只對一個磁碟進行一項軟體測試) * QSoft設定system memory跟resident memory兩者跑出來的效能有天壤之別 新設定值：2G空間 fat32 4k resident memory ================================ 測試結果 (以下兩張實測圖) http://dl.dropbox.com/u/8246392/Ramdisk/Test%20of%206%20ramdisks.png http://dl.dropbox.com/u/8246392/Ramdisk/Test%20of%206%20ramdisks_2.png * 後來重測Qsoft http://dl.dropbox.com/u/8246392/Ramdisk/Test%20of%20Qsoft.png 跟原本測試軟體的設定不一樣 但影響測試最大的是ramdisk軟體內部參數 * 新增Vsuite SCSI與Direct IO兩種模式的比較 http://dl.dropbox.com/u/8246392/Ramdisk/Test%20of%20VSuiteD%26S.png (以下是CDM的數據 ATTO無法複製數據就沒貼上來了 請看圖) (順序同上述試軟體列表 由上而下) Superspeed

QSoft > Vsuite(D) > Superspeed > Vsuite(S) > ImDisk > Dataram > Buffalo 2. ImDisk 4K QD32特強 但ATTO的128k 256k寫入異常低落 ??? 3. 這六款軟體中 只有Buffalo在OS啟動前就產生Ramdisk 4. 我主觀評比: V功能最強大 B最簡潔直覺 D介於V跟B之間 I Q S的設定介面都不好用 --
