The previous OCZ SSDs: Core v1 (SATAII): 30GB, 60GB, 120GB with Read Speed 153MB/s and Write Speed ~80MB/s Core v2 (SATAII + miniUSB): 30GB, 60GB, 120GB, 250GB with Read Speed 170MB/s and Write Speed 90MB/s The problem with these versions is that they have a random write speed of about 20MB/s. Also, when running an operating system like Vista from the drive you may experience stuttering or lag because there is no on-board cache. These new drives (I thought they would be called Core v3) have onboard cache to remove the stutter and lag effect. 64MB of cache! They also improve random writes, like the expensive Intel drives. I wasn't expecting sequential writes to be so fast. 160MB/s! Wow! If you want a cheap drive to boot your OS core files from, then this is the drive for you. I'm pretty sure it boots up XP in 5 seconds or less. Possibly 10 seconds maximum if you include from BIOS screen. This is vista booting on older Core v1's. When it actually gets to vista, it takes maybe 3 seconds max. 30GB for US$129, now just gotta wait for it to his Aus. Who wants this drive?
