The far I know about your PC is support SATA 2 port and that limit of 3 Gb/s and the SSD 530 MB/s, Let's do some Math: 1 MB = 0.0078125 Gb, 530 MB = 4.14063 Gb, 3 Gb - 4.14063 Gb = -1.14063 Gb LOST transfer rate SATA 2 port support 3Gb = 384 MB = 298 MB actual speed so batter to get something less speed because it will give you the same performance but you will same some money like
