RAID 1 (Mirroring and Duplexing) Comparing mirroring and duplexing Mirroring is the simplest method of avoiding data loss when a single disk fails. During writes, data is sent to both disks. During reads, different data can be read from both disks, which provides good read Performance. Duplexing is another form of keeping a copy of data. Where mirroring uses a single controller, duplexing can also handle a controller failure. Duplexing requires an operating system that supports RAID 1.
This site says cost of tiling per square metre is between $95 and $170 psm for floor tiles and $90 and $160 for wall tiles. Those prices include tiles so take $30 psm off those.
Posted. Hi, we deceided to go through our builder to get the floor tiles in our project home layed. They have charged us about $8500 for about 100 metres square of a $30 tile (tile included in price).This would make it about $55 per metre to lay.y DP is a tiler and the lowest amount he charges per metre is $50. THis does not include the tiles, glue or grout. So $8500 for a floor sounds about right.
