Testing Intel, Samsung & SanDisk SATA SSD

While working on the service architecture for one of our projects, I considered several SATA SSD options as the possible main storage for the data. The system will be quite write intensive, so the main interest is the write performance on capacities close to full-size storage. After some research I picked several candidates (I show […]

Disaster: MySQL 5.5 Flushing

We raised topic of problems with flushing in InnoDB several times, some links: InnoDB Flushing theory and solutions MySQL 5.5.8 in search of stability This was not often recurring problem so far, however in my recent experiments, I observe it in very simple sysbench workload on hardware which can be considered as typical nowadays.

Intel 320 SSD read performance

(this is cross-post from http://www.percona.com/blog/) While PCI-e Flash cards show great performance, I am often asked about alternatives, as price for PCI-e cards is still significant and not acceptable for small companies and startups. Intel 320 SSD appears to be a popular drive with a quite acceptable price. I wrote about write performance of these […]

Intel 320 SSD random write performance

There is wide range of SATA drives on market, and it is hard to pick one, but Intel SSD are probably one of […]

RAID vs SSD vs FusionIO
