Use of SSDs drives are substantially faster than traditional disks and thus can provide performance benefits to most applications. 使用SSD硬盘要比使用传统磁盘快许多,因此可以为大多数应用程序提供性能增益。
Tablespaces that have a lower sequentiality ratio also are better candidates for SSDs. 具有较低连续率的表空间也比较适合放在SSD上。
Sure, we have redundant array of independent disks ( RAID) scaling and NAND flash solid-state disks ( SSDs), but as noted by IBM Almaden Research, the time scale differences of the access time gap are massive in human terms. 当然可以,我们有独立磁盘冗余阵列(RAID)扩展和NAND闪存的固态磁盘(SSD),但正如IBMAlmaden研究表明的那样,存取时间间隙的时间尺度差异在人类语言中是巨大的。
But although SSD costs are declining every quarter, SSDs are still more expensive than HDDs. 但是,虽然SSD的成本每个季度都在递减,但是SSD仍然比HDD昂贵。
So, what data should be placed on an SSD to maximize performance? 那么,什么样的数据应放在SSD中,从而最大限度地提高性能?
All existing data is moved underneath the cover from regular disk drives to SSDs automatically. 所有现有数据都在后台从常规硬盘驱动器自动移动到SSD。
We then tested several scenarios after migrating portions of the database application to SSDs. 然后,我们将数据库应用程序的一部分迁移到SSD,对一系列的场景进行测试。

Does clustering ( or for that matter, poor clustering) really matter when using SSDs? 当使用SSD的时候,集群(或者说,不好的集群)真的会有影响吗?
I ran storage specific tests, I ran overall system tests and separate tests as well and I found the obvious that the SSD is faster. 我跑存储特定的测试,我跑了整个系统的测试和单独测试以及,我发现明显,SSD的速度更快。
Competition in the enterprise-class solid-state disk ( SSD) drive market is heating up with new players and products. 竞争在企业级固态磁盘(SSD)驱动器市场正在升温,新的球员和产品。
