The new OCZ Vector 150 is a great solid-state drive, but it doesn't really have anything that you haven't seen before.
Made to be the upgraded version of the Vector drive that came out last December, the Vector 150 looks almost exactly the same as its predecessor. On the inside, the drive uses more affordable NAND flash memory but shares the same controller. To balance the value out, it now supports AES-256 data encryption, which the Vector doesn't.
In my testing, the new drive showed slower performance than the Vector in certain tests and faster in the others. At launch, it carries the same price tag as the Vector, about $1 per gigabyte.
After almost a year, I expected the Vector 150 to have more to offer, or at least have a lower price. For this reason, the OCZ Vector 150 is a great drive but won't be an excellent choice until its street price is on par with those of its competitors, such as the Samsung 840 Evo.

The OCZ Vector 150 has an aluminum chassis, which makes it feel solid and look expensive. It has the same pattern as the original Vector. In fact, the only difference between the two is that the 150 says "Vector 150" on it; the original Vector only says "Vector."

On the inside, the two also share the same OCZ Barefoot 3 controller, but the Vector 150 uses 19nm MLC Flash NAND from Toshiba, as opposed to OCZ's home-grown 25nm MLC Flash NAND. The smaller flash memory size means that you can put more memory cells per square inch, leading to a cheaper manufacturing price. This will also mean differences in performance and endurance.
Despite using the same controller, the Vector 150 supports AES-256 hardware encryption. This is a great new feature for business users. For home users, this makes no difference, since the encryption needs to also be supported by the host, such as a laptop's motherboard, and most home computers don't include the hardware encryption feature.
OCZ says the new Vector 150 drive has endurance of 50GB per day. This means if you write 50GB to the drive every day, it will still last at least five years before it becomes unreliable. This is significantly better than the 20GB-per-day rating of the Vector. Most of the time, however, we don't write 50GB to a computer's internal drive each, and especially not every, day.
The reason SSDs have an endurance rating is that, unlike regular hard drives, all SSDs come with a finite number of program/erase cycles, meaning that you can write to them only so many times before you can't anymore. For most users, SSDs' endurance ratings are so high that it's not really an issue. (Read more about SSDs here.)
Other than that, the Vector 150 has a standard 2.5-inch internal drive design and supports the latest SATA 3 (6Gbps) I/O interface. It's also backward-compatible with SATA 2 and the original SATA standard. In other words, it can be used virtually anywhere a regular hard drive of the same standard is used.
The drive's package includes the SSD itself, a desktop bracket to make it easily fit inside a desktop computer, and a serial number for a retail copy of Acronis True Image 2013, which is one of the best backup and drive-cloning software for Windows. You can download this software and use the key to activate it.
