Unlike other SandForce-based SSDs, the SSD720 doesn't have RAISE (SandForce's NAND redundancy feature) enabled, making it offer slightly higher capacity, at the expensive of slightly higher risk of data loss. This is, however, is a new trend since, per SandForce, RAISE is not exactly necessary for general consumers; it's more for enterprise products.
Cost per gigabyte
Generally prices of SSDs are subject to a great deal of fluctuation, mostly for the better. For now, the new SSD720 consistently cost less then $1 per gigabyte across all of its capacities, low enough to be called affordable. The 256GB version, for example, can be had for just around $225 or 88 cents per gigabyte.
The drive is not the most affordable on the charts, but for a drive that's relatively new on the market, its initial price point is a good start. It's likely that it will get even lower in the coming months.

I reviewed the 256GB-capacity of the SSD720, and used it both as a secondary drive and as the main drive that hosts the operating system.
As a secondary drive, the SSD offered the real-world sustained write speed of 231MBps, which is above average among all SATA 3 SSDs. In reading test, the drive did better with 270MBps.
When used as the main drive, SSD720's copy speed was reduced to just 109MBps, below the average on the charts. Note that in this test, the drive performed both reading and writing at the same time. Nonetheless, it helped improve the overall performance of the computer a great deal. The test system took just about 11 seconds to boot up and about 5 seconds to shut down, much faster than when it used a hard drive as the main storage. Applications also loaded much more quickly. Compared with other SSDs, however, it wasn't much different, and slightly slower than many. Since SSDs are generally very fast compared with standard hard drives, it's hard to quantify the difference between them when it comes to the overall performance of a computer.
Comprehensively, the SSD720's performance didn't match that of the Corsair Neutron GTX or the Samsung 840 Pro but still provides a significant boost when compared to any hard dive.
