SSDs and Distributed Data Systems
A few obvious conclusions are that SLC SSDs are priced roughly the same as memory. In a sense SLC SSDs are better than memory since they are persistent, but if keeping all your data in memory sounds expensive then so will SLCs. And in any case you can’t eliminate memory caching entirely as at least some part of the index likely needs to reside in memory even with the faster access times SSDs provi

Intel Consumer SSDs: Not appropriate for databases (evanjones.ca)
[ 2010-September-03 10:04 ] I have been testing one of Intel's "consumer" SSD (X25-M G2) to see if it stores data durably, meaning that if the disk claims the data has been written, it actually survives a power failure. This is important because you want your airline ticket to stay purchased after your buy it, even if the system crashes. The conclusion is that this SSD can lose data in power failu
FlashCache: first experiments
I wrote about FlashCache there, and since that I run couple benchmarks, to see what performance benefits we can expect. For initial tries I took sysbench oltp tests ( read-only and read-write) and case when data fully fits into L2 cache. I made binaries for FlashCache for CentOS 5.4, kernel 2.6.18-164.15, you can download it from our testing stage. It took some efforts to make binary, you may get
