NVDIMM在用作内存数据库系统存储器时可以匹配传统DRAM的速度，同时提供完整的内存数据库持久性。那么为什么还有人要用带***诱导事务日志的内存数据库系统呢？这里有多种理由，包括成本，因为GB规模的NVDIMM成本要大于DRAM；想要使用非IntelRomley和Grantley的平台；要求的数据库大小(AgigATech公司的NVDIMM支持高达128GB的总内存容量)。如上述数字所示，增加事务日志实现数据持久性将降低内存数据库系统的性能，但IMDS+TL组合在插入、更新和删除操作时仍能超越传统磁盘型数据库管理系统的性能。
今后用户会遇到的另外一个问题是他们所选的内存数据库系统是否支持将NVDIMM用作主要内存。如前所述，McObject的eXtremeDB内存数据库系统包括许多功能——在产品开发早期就加入的，用于支持与电池供电型RAM的交互——这些功能可以用NVDIMM平顺地***数据库。使用没有这些功能的内存数据库系统可能导致更高的复杂性，并且在实现可工作的解决方案之前需要很大的开发和测试工作量。
另外值得注意的是，本文讨论的数据库持久性——也就是确保数据库和所有提交的事务能在发生系统故障事件时得到***——有别于高可用性，或不***操作的能力。虽然两种技术都是想帮助数据库经受住故障，但如前所述，高可用性通常是通过***实现的，故障转移时间单位是毫秒。相反，持久性——带事务日志的内存数据库系统或将NVDIMM用作主存所能达到的——不保证消除***时间。使用NVDIMM或事务日志进行数据库***通常是自动的，但两者***有可能的使用场景是在意外的系统宕机之后，这意味着冷重启(如重新启动)这样的时长为分钟级的过程。开发人员在考虑用这些技术克服易失性问题时应该理解数据库高可用性和持久性之间的区别。
