今天兴冲冲的从网上拉下来了一个superspeed Ramdisk与Supercache的安装文件据说是带key的乐呵的很
结果发现下来一水的序列号用户名是Evaluation 也罢可能这个craker有这个癖好安装一下通过很高兴心想这下总算能够用到不限制时间的superspeed软件了结果一查授权差点没气晕 supercache的授权是一个月（不填写序列号也是一个月）ramdisk的授权就只有短短的14天了有这号跟没有还是一样不过不太清楚是否功能上有所限制可以通过序列号解除
看来如果想用也只有一个办法就是使用安装纪录软件在安装的时候记录下此软件的所有安装信息等快到期了就卸载掉从新装再获得14天跟30天的试用期虽然办法很笨不过终究还算个办法了
ramdisk新版的改进较7.x有了很大改观首先支持多个虚拟磁盘了删除建立虚拟磁盘也不再需要从启动系统了
优点比起其他内存盘软件主要是支持自动备份以及NTFS系统和磁盘压缩这样可以用尽量少的代价换来较高的性能提升内存的利用率也会提升很多
Supercache应该还是在服务器领域用的较多主要是用来减轻磁盘负担提升性能的只要你内存足够大使用内存为硬盘建立一个影卷都不成问题当然谁没事做会把那么多内存用来做这个呢除非是超高档服务器想象一下一个下载站把那些读取最频繁或者干脆整个站点全部塞到内存盘中会是什么速度

Ramdisk简洁的界面

比硬盘要快不少的速度

毫无疑问这比技嘉出的那个Ramdisk要实惠得多起码不用添置物理设备同时又具备相对较好的数据长期储功能速度上嘛对比下吧
