The Micron P320h SSD is an SLC-based PCIe solid-state storage device which claims to provide the highest read throughput of any server-grade SSD, and at Micron’s request, I recently took some time to put the card through its paces, and the numbers are indeed quite impressive. For reference, the benchmarks for this device were performed [...]
Testing Virident FlashMAX 1400
May 4, 2012 By 4 Comments
I still continue to run benchmarks of different SSD cards. This time I show numbers for Virident FlashMAX 1400. This is a MLC PCIe SSD device. There are couple notes on these results. First, this time I use a different server. For this benchmark it is Cisco UCS C250, while for previous results I used [...]
Testing Fusion-io ioDrive
May 3, 2012 By 2 Comments
Following my series of posts on testing different SSD, in my last post I mentioned that SATA SSD performance is getting closer to PCIe cards. It really makes sense to test it under MySQL workload, but before getting to that, let me review the same workload on Fusion-io ioDrive PCIe card. This is yet previous [...]
Testing Intel SSD 520
May 1, 2012 By 8 Comments
Following my previous benchmarks of SATA SSD cards I got Intel SSD 520 240GB into my hands. In this post I show the results of raw IO performance of this card.
Testing STEC SSD MACH16 200GB SLC
April 25, 2012 By 9 Comments
Following my previous benchmark of Samsung 830, today I want to show results for STEC MACH16 SATA card, 200GB size, this card is based on SLC, and regarding STEC website, it is an enterprise grade storage.
Testing Samsung SSD SATA 256GB 830 – not all SSD created equal
April 25, 2012 By 12 Comments
I personally like PCIe based Flash, but from a pricing point our customers are looking for cheaper alternatives. SATA SSD is an options. There is many products based on MLC technology, and Intel 320 I would say is the most popular. I do not particularly like its write performance – I wrote about it before, [...]
ext4 vs xfs on SSD
March 15, 2012 By 26 Comments
As ext4 is a standard de facto filesystem for many modern Linux system, I am getting a lot of question if this is good for SSD, or something else (i.e. xfs) should be used. Traditionally our recommendation is xfs, and it comes to known problem in ext3, where IO gets serialized per i_node in O_DIRECT [...]
Introducing new type of benchmark
February 25, 2012 By 16 Comments
Traditionally the most benchmarks are focusing on throughput. We all get used to that, and in fact in our benchmarks, sysbench and tpcc-mysql, the final result is also represents the throughput (transactions per second in sysbench; NewOrder transactions Per Minute in tpcc-mysql). However, like Mark Callaghan mentioned in comments, response time is way more important [...]
Percona Server vs MySQL on Intel 320 SSD
February 23, 2012 By 21 Comments
If you are terrified by the stability of the results in MySQL in my previous post, I am going to show what we can get with Percona Server. This is also to address the results presented there Benchmarking MariaDB-5.3.4
Some fun with R visualization
February 23, 2012 By 5 Comments
My previous post I finished with the graph with unstable results. There I won’t analyze causes, but rather I want to show some different ways to present results.
