Kingston UV400 480GB TLC SSD Review
IOMeter Mixed Performance
Our mixed performance test is conducted in the same manner as our sequential tests, but once the drive is conditioned we run our test profile to look at performance in various read/write states. We start the test with 100% reads and then add write data into the mix in 10% increments until we end up with no reads at all in the workload.
The Kingston UV400 480GB drive starts out great in our 128KB sequential mixed workload test with 100% reads, but the performance drops off as writes are added and performance never comes back due to the the SLC cache filling up. Luckily other TLC drives have this performance characteristic.
When looking at 4KB Random mixed workload performance again found that performance tapers off as the number of writes increases, but we did see performance increase with 100% writes.
Let’s take a look at temperatures!
