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 cards, and now let’s take look on a random read workload.
I used a Cisco UCS C250 as base hardware, comparing in it:
For simulating the workload I used sysbench’s fileio random reads. Scripts and raw results available on Launchpad.
Let’s see throughput results:
|threads||Intel 320||Intel 320 2 strip||RAID10||ratio Intel 320 / RAID10||ratio Intel 320 2 strip / RAID10|
|threads||Intel 320 SSD||Intel 320 SSD strip||RAID||ratio RAID/Intel 320||ratio RAID/Intel 320 strip|
As conclusion, this card provides great read performance. A single card provides 5-8x better throughput and 10-14x better response time. Striping helps to increase throughput in 8-10x and response time in 10-22x.
While there are questions about write performance (see my previous post), I think this card is very suitable for read-intensive tasks, where you can expect significant improvements.
