<p>Companies and authorities of today often handle large amount of data, not unusually with a restricted content which should be kept secret from outsiders. One way of accomplish this is to encrypt stored data in real time. For this a hardware solution is ideal since it can be independent, fast enough, and easily added to already existing systems.</p><p>This report is a starting point to achieve this with two of the most common mass storage standards SATA and SCSI in focus. It is based on the task to develop a FPGA based SATA controller and investigate the possibility to ”speak” SCSI with SATA devices.</p><p>The working process has involved theoretical studies, system design, test driven development using simulations and hardware tests and technical investigation.</p><p>The thesis resulted in a SCSI-to-SATA translation investigation pointing out difficulties and presenting a translation model. A SATA host was also implemented in VHDL on a Virtex-5 FPGA that can execute a number of SATA commands on different devices. Simulations performed shows that the total latency reaches one <em>μ</em>s/32 bits in the SATA host and that should not be much of a problem for most applications in a possible bridge solution. </p>
