Comparison of nine Serial ATA RAID 5 adapters
Feature comparison (2)
In order to provide an overview of the features supported by the RAID-adapters in our roundup, we have put all relevant features into a table. Due to the large amount of data, the table had to be split into two tables found on this and following page. To free the tables from the standard page width, some CSS-trickery was necessary.
1 Excluding 168-pins obligatory SDR SDRAM DIMM
2 Including 256MB PC133 SDRAM worth € 45, -
3 Memory not provided, a minimum of 64MB is required
