I am looking for opinion about an idea to build up low-cost high-performance server out of consumer-grade parts. I would use one of the Entry-level servers with addition of:
- hardware RAID controller LSI MegaRAID SAS2108 with 512 MB Cache
- iBBU battery for RAID Ctrl
- and 4 consumer-grade MLC SSD disks, for example Samsung 840 Pro
- RAID array would be RAID 5 or 10
RAID controller with its internal 512 MB cache would take up much of disk writes, so SSD's would last much longer. I think.
On Linux machine on it I would add "noatime" to fstab to reduce disk writes even more (and gain on speed). For Windows platform I have no idea of such a filesystem parameter.
What do you think?
For the price of one single server-grade SSD disk I would get whole server.
