Kingston SSDNow UV400 240 GiB SSD Review
Compressible Data Test
Contents
As you will have gathered from the previous page, we measured the performance of each drive using CrystalDiskMark.
It is important to note that we connected the SSDs to a SATA-600 port on our motherboard rather than a SATA-300 port, which could cause performance limitations.
First, we set CrystalDiskMark to “All 0x00 Fill mode” to evaluate the performance of the SSD when dealing with compressible data.
On the sequential read benchmark, the Kingston SSDNow UV400 240 GiB performed similarly to the SanDisk SSD PLUS.
On the sequential write benchmark, the Kingston SSDNow UV400 240 GiB was 25% faster than the SanDisk SSD PLUS.
On the random read test with 512 kiB blocks, the Kingston SSDNow UV400 240 GiB was 12% faster than the SanDisk SSD PLUS.
On the random write test with 512 kiB blocks, the Kingston SSDNow UV400 240 GiB was 10% faster than the SanDisk SSD PLUS.
On the random read benchmark with 4 kiB blocks, the Kingston SSDNow UV400 240 GiB was on a technical tie with the SanDisk SSD PLUS.
On the random write benchmark with 4 kiB blocks, the Kingston UV400 240 GiB was 49% slower than the SanDisk SSD PLUS.
