Cost per gigabyte
At around $217 for 256GB, the SanDisk Ultra Plus costs just 85 cents per gigabyte. Its 128GB version costs about the same at 86 cents per gigabyte. This makes the new SSD one of the most affordable on the market. The recently reviewed OCZ Vector, for example, costs somewhere between $1.05 to $1.17 per gigabyte, and the Samsung 840 Pro is close to $1 per gigabyte. Even the older SanDisk Ultra is about $1 per gigabyte.
Prices of SSDs have been very volatile lately; you can expect them to get even lower in coming months.
The SanDisk Ultra Plus didn't impress me much in my testing. I reviewed the 256GB-capacity drive both as a computer's main drive hosting the operating system and as a secondary drive that works as extra storage space.
When used as the main drive, the Ultra Plus 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. Applications also loaded much more quickly. Compared with other SSDs, however, it wasn't much different, though 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.
What can be easily quantified, however, is the data-transferring speed, or sequential read/write performance, which is not exactly an SSD's strength. In this test, when used as the main drive of a computer and performing both read and write duties at the same time, the Ultra Plus scored 107MBps, just about average among all SSDs tested. A faster drive, such as the Samsung 840 Pro, managed about 170MBps in this test.
When used as a secondary drive, the Ultra Plus did much better in data transfer tests, at 168MBps for writing and 227MBps for reading. However, these still were just about average on the charts.
Overall the SanDisk Ultra Plus offered a typical SSD experience in our tests and would wow anyone who has decided to move up from a hard drive.
