Enthusiast SSDs may get all of the fame and glory, but it’s the value brands that always sell the most drives. As a relative newcomer that doesn’t rely on SandForce controllers like many other vendors do, can SanDisk’s Marvell-equipped Ultra Plus deliver that “Ultra” good value we’re looking for?
Finally, we reach the first of our real-world tests where there are no unusual testing or scoring algorithms to leave us scratching our heads, just simple tests to see how an SSD changes actual system performance.
For the File Transfer test we took a 4.5GB compressed archive and measured how much time was required to transfer the file to another folder on the same drive. Keep in mind that with a hard disk, this requires the actuator arm to seek back and forth between the source and destination sectors on the disk platter, with the destination sectors often not sequentially aligned. In contrast, any SSD can concurrently perform read and write operations simultaneously on any NAND chip without regard to spatial considerations of bits strewn randomly around a disk platter, which gives them a large advantage here.
For the first of our real-world tests, the Ultra Plus slots in a cool second spot, possibly due to the nCache at work again. It’s one hell of a value when a budget drive manages to compete with enthusiast models.
Either you’ve heard of FLAC, or it is an integral part of your digital life. But iTunes and Apple devices do not support FLAC files, leaving those with discerning ears forced to use Apple’s Lossless codec. dBpoweramp makes it possible to convert between them utilizing as many threads as are available to the system.
In this test, we take 10 albums amounting to 4GB of FLAC files and convert them to Apple’s lossless format. This creates exactly 3.96GB of new data. This scenario is even more applicable for those users with six or more physical CPU cores available, because as the core count increases, the more the storage system will become the actual bottleneck. Our test rig is limited to only a quad-core processor, but even then we can see clear differences amongst the various contenders.
Our dBpoweramp test both reads and then writes 4GB of data, and here SanDisk’s solid-state drive fares a little more average, smack in the middle of the pack.
