I have got 2 Seagate Momentus XT (500 GB) drives. They a hybrids (4 GB NAND flash built in) and 32 MB cache and SATA 6Gb/s interface. They are very very fast, faster than my old 300 GB Velocirator infact...... But......my question is - would I gain anything with them in RAID 0 vs. my now single AHCI? I cant figure out if the drives can use the advantage of 2 x 32 MB cache and the 2 x 4 GB NAND in RAID mode ...... Anyone have an idea??
