on the same PC without and with RAM caching using 1GB of random data.
Specs:
Core i7-3930k, 64GB RAM, not O.C.'d, Windows 7 64bit Ultimate
ASUS P9X79 Deluxe with additional LSI SAS/SATA3 controllers 6Gb/s
All HDDs are latest gen Seagate Barracuda, All SSDs are Plextor M5S 256GB.
This PC is a dedicated sample server in a music production setup. It stores and serves
soft synth audio samples for various instruments at the same time (30+) to be recorded and played
back through a software sequencer (SONAR X2 Producer). The data is hence mostly static after installation.
RAM caching with FancyCache v0.8beta
ONLY read caching; write caching is too unsafe, and for this application, almost useless
since the data on disks storing samples is mostly static..
Most important are READ rates
On each line below:
LEFT tables : results without RAM caching
OTHER tables : results with read-only RAM caching active (default config & cache size 4GB)
1. HDD E: - Seagate 3TB connected to P9X79 main controller @ 6Gb/s
2. HDD S: - Seagate 3TB connected to LSI through SATA3 removable tray bay @ 6Gb/s
Note: the limitation seems to be the tray itself.
3. HDD D: - Seagate 3TB ASUS cached by SSD using P9X79 Marvell controller @ 6Gb/s
4. SSD F: - Plextor M5S 256GB connected to LSI controller @ 6Gb/s
5. HDD C: - The SYSTEM disk - Seagate 1TB (older gen) connected to the P9X79 main controller @ 6Gb/s
