Don’t Spin Your Data, Use SSDs!

 | September 9, 2016 |  Posted In: MySQL


This blog post discussed the advantages of SSDs over HDDs for database environments. For years now, I’ve been telling audiences for my MySQL Performance talk the following: if you are running an I/O-intensive database on spinning disks you’re doing it wrong. But there are still a surprising number of laggards who aren’t embracing SSD storage […]

performance boost for SSD

In this blog post, we’ll discuss how a small innodb_page_size can create a performance boost for SSD. In my previous post Testing Samsung storage in tpcc-mysql benchmark of Percona Server I compared different Samsung devices. Most solid state drives (SSDs) use 4KiB as an internal page size, and the InnoDB default page size is 16KiB. I wondered […]

Testing the Virident FlashMAX II

 | March 21, 2013 |  Posted In: Benchmarks

Approximately 11 months ago, Vadim reported some test results from the Virident FlashMax 1400M, an MLC PCIe SSD device. Since that time, Virident has released the FlashMAX II, which promises both increased capacity and increased performance over the previous model. In this post, we present some benchmark results comparing this new model to its predecessor, […]

On SSDs – Lifespans, Health Measurement and RAID

 | October 12, 2012 |  Posted In: MySQL

Solid State Drive (SSD) have made it big and have made their way not only in desktop computing but also in mission-critical servers. SSDs have proved to be a break-through in IO performance and leave HDD far far behind in terms of Random IO performance. Random IO is what most of the database administrators would […]
