And there you have it - the best sequential speeds we've seen from any QLC product. Factory sequential specs are 3,200/2,900 with CrystalDiskMark. We have no issues significantly exceeding both specifications despite the fact that our user state is OS Disk 50% filled. These results also serve to illustrate the fact that data read back from QLC is served up as fast as other typed of flash.

The Rocket Q comes very close to hitting the 6,000-point threshold we are looking for in terms of total read score. Our test subject comes in just below Samsung's 970 EVO Plus and beats out the MDD BPX Pro. This is quite a feat considering that we are dealing with QLC, which is at a disadvantage when reading back random data at higher queue depths. In terms of overall scoring, the Rocket Q delivers a remarkable 18K. Impressive.

The read results serve to illustrate our assertion that QLC performance does suffer some at high queue depths. Random writes are happening in the drives SLC cache, and we see an impressive number of almost 800K.
