Sequential Write

We really want to pay close attention to write performance. These days, enthusiasts pay more for this specification since read performance is almost always at the limit of SATA 6Gb/s anyway. 

The two smaller drives with Toshiba A19 TLC get close enough to steady state during this portion of the test script that their numbers waver. We also see that a capacity advantage doesn't always translate to significantly higher write performance when it comes to TLC flash. The 960GB TLC drive delivers less sequential write performance than the smaller 480GB MLC versions. The same performance drop-off also occurs in the 480GB TLC drive compared to 240GB MLC drives.
