OCZ's Vector 150 is a direct replacement for the Vector. It uses OCZ's own Indilinx Barefoot controller, which we first saw on the original OCZ Vector. Unlike the Vector, which used Micron flash, the Vector 150 uses Toshiba flash. This move seems to be related to a recent statement by OCZ that they are having difficulties acquiring enough flash chips to satisfy demand. The Vector 150 is a little bit (2%) slower than the Vector, a difference that you'll never notice during real-life usage, which also depends on the application used. Performance matches that of typical high-end SandForce drives, but falls a bit short compared to the latest and greatest from Toshiba and Samsung. The Vector 150 improves steady state performance, which results in higher longer-term performance even when the drive is closer to its maximum capacity. This will provide an additional performance boost versus other drives with worse steady state performance.
The Indilinx Barefoot controller has been used on several OCZ products for a while now, and we didn't hear of any horror stories involving it, so the drive should be stable and without issues; we also didn't encounter any problems in our testing.
OCZ includes TrueImage HD with the Vector 150 to make sure moving your data from your HDD to this new SSD will work quickly and without any problems—you should be up and running in no time.
With a price of $240 for the 240 GB version, the Vector 150 is quite expensive when compared to other offerings on the market. Its biggest threat seems to be Samsung's 840 Pro, which sells for less and offers higher performance. Another option for the more price-minded buyer are older SandForce drives that offer better performance per dollar, but might not be as fast. OCZ should, in my opinion, shave another $20 or $30 off the price to make it more competitive.
While not directly related to the product itself, OCZ has recently gone through some financial trouble. These news have me worry slightly about what will happen if OCZ runs into more trouble now, as it might even affect warranties for existing products. OCZ is giving a five-year warranty with the Vector 150, which suggests that they are confident in their product and the company's future.
