Super Talent ST4 64G 号称4ch的dongle 2. Apacer AH350 16G 号称...最轻的usb 3.0 dongle 不罗嗦..直接上数据 ST4 on I公司原生USB 3.0 ----------------------------------------------------------------------- CrystalDiskMark 3.0.1 x64 (C) 2007-2010 hiyohiyo Crystal Dew World : http://crystalmark.info/ ----------------------------------------------------------------------- * MB/s = 1,000,000 byte/s [SATA/300 = 300,000,000 byte/s] Sequential Read : 126.334 MB/s Sequential Write : 82.552 MB/s Random Read 512KB : 120.605 MB/s Random Write 512KB : 40.940 MB/s Random Read 4KB (QD=1) : 17.800 MB/s [ 4345.8 IOPS] Random Write 4KB (QD=1) : 1.207 MB/s [ 294.7 IOPS] Random Read 4KB (QD=32) : 19.598 MB/s [ 4784.5 IOPS] Random Write 4KB (QD=32) : 1.188 MB/s [ 290.0 IOPS] Test : 100 MB [E: 0.0% (0.0/58.6 GB)] (x5) Date : 2012/01/17 7:15:59 OS : Windows 7 Ultimate Edition [6.1 Build 7600] (x64) ST4 on NEC晶片 ----------------------------------------------------------------------- CrystalDiskMark 3.0.1 x64 (C) 2007-2010 hiyohiyo Crystal Dew World : http://crystalmark.info/ ----------------------------------------------------------------------- * MB/s = 1,000,000 byte/s [SATA/300 = 300,000,000 byte/s] Sequential Read : 123.616 MB/s Sequential Write : 82.177 MB/s Random Read 512KB : 117.352 MB/s Random Write 512KB : 40.188 MB/s Random Read 4KB (QD=1) : 15.089 MB/s [ 3683.9 IOPS] Random Write 4KB (QD=1) : 1.152 MB/s [ 281.2 IOPS] Random Read 4KB (QD=32) : 17.837 MB/s [ 4354.8 IOPS] Random Write 4KB (QD=32) : 0.000 MB/s [ 0.0 IOPS] Test : 100 MB [I: 0.0% (0.0/58.6 GB)] (x5) Date : 2012/03/01 17:32:38 OS : Windows 7 Enterprise Edition SP1 [6.1 Build 7601] (x64) 4K QD 32接在 NEC反而测不完, 会当掉.. 懒得去找原因. 数据跟楼上I公司原生非常接近. 2.
