作者 capri75 (capri) 看板 Storage_Zone 标题 [测试] Ramdisk大乱斗:Buffalo/Dataram/ImDisk/QSoft/VSuite/SuperS 时间 Fri Feb 18 00:09:44 2011 ─────────────────────────────────────── 既然要做Ramdisk测试 那就乾脆多做几间的比较 来个大乱斗 XD 先把心得说在前面 数据看起来很怪 Dataram狂输Vsuite 加上ImDisk的部分写入异常低落 我觉得奇怪的部分都有重复测过至少三次 变化不大 这次测试感觉用处不大 但想说都已经花时间测完了 还是PO上来给大家鞭一鞭 不知道到底哪里出了问题... =============================== 测试环境 i3-530 DDR3-1333 12G(威刚4G*3) ASrock H55M-GE Win7 x64 (刚重灌完的状态 仅安装驱动程式与win更新 关UAC) =============================== 测试对象 SuperSpeed RamDisk Plus 11.5.390 x64 (15天试用版) 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以内免费) http://memory.dataram.com/products-and-services/software/ramdisk QSsoft RAMDisk "Enterprise" 5.3.2.12 (试用版) http://members.fortunecity.com/ramdisk/RAMDisk/ramdiskent.htm (网页似乎故障 我稍早下载时还是正常的) VSuite Ramdisk 服务器版 V4.6.7531.1240 (15天试用版) http://www.romexsoftware.com/zh-cn/index.html ================================ 测试设定 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 六个ramdisk 全都从官方网站下载并安装 1G容量 FAT32格式 4096位元组配置单位 没有放置任何档案或其他系统设定(如pagefile 系统变数或IE暂存等) 以ATTO Disk Benchmark v2.46与Crystal Disk Mark 3.0.1 x64两个软体测试 (同一时间内只对一个磁碟进行一项软体测试) * QSoft设定system memory跟resident memory两者跑出来的效能有天壤之别 新设定值：2G空间 fat32 4k resident memory ================================ 测试结果 (以下两张实测图) 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 * 後来重测Qsoft http://dl.dropbox.com/u/8246392/Ramdisk/Test%20of%20Qsoft.png 跟原本测试软体的设定不一样 但影响测试最大的是ramdisk软体内部参数 * 新增Vsuite SCSI与Direct IO两种模式的比较 http://dl.dropbox.com/u/8246392/Ramdisk/Test%20of%20VSuiteD%26S.png (以下是CDM的数据 ATTO无法复制数据就没贴上来了 请看图) (顺序同上述试软体列表 由上而下) Superspeed

ImDisk 4K QD32特强 但ATTO的128k 256k写入异常低落 ??? 3. 这六款软体中 只有Buffalo在OS启动前就产生Ramdisk 4. 我主观评比: V功能最强大 B最简洁直觉 D介於V跟B之间 I Q S的设定介面都不好用 --
