SSD速度测试 Using X-Bench, we saw the 128GB model—the APPLE SSD TS128C—give the following numbers: Seq Uncached Write: 134MB/sec (4k blocks) Seq Uncached Write: 158MB/sec (256k blocks) Seq Uncached Read: 68.5MB/sec (4k blocks) Seq Uncached Read: 165.8 MB/sec (256k blocks) Random Uncached Write: 32.18MB/sec (4k) Random Uncached Write: 116.5 (256k) Random Uncached Read: 8.27 (4k) Random Uncached Read: 108.56 (256k) Comparing this to my 15" unibody MacBook Pro, which has a 320GB 5400RPM Hitachi hard disk, the difference is significant: Seq Uncached Write: 8 MB/sec (4k blocks) Seq Uncached Write: 39.5 MB/sec (256k blocks) Seq Uncached Read: 5.4 MB/sec (4k blocks) Seq Uncached Read: 18 MB/sec (256k blocks) Random Uncached Write: 0.7 MB/sec (4k) Random Uncached Write: 15.14 MB/sec (256k) Random Uncached Read: 0.25 MB/sec (4k) Random Uncached Read: 12.51 MB/sec (256k) This is obviously not up to Sandforce levels, but it's really fast nonetheless.
