While increasing the storage capacity and reducing the overall size of the chip, SSD665p can still use the capacity of single-core 1024GB. In other words, you don't have to expect a huge improvement in the capacity and performance of the new model, but you can look forward to a lower price.

During the live demonstration,Intel Intel SSD 665p with pre-manufactured firmware was compared with 660p with the same capacity of 1TB, and both SSDs were installed in the same model.ASUS In a laptop computer.

Results The Beta version of Crystal DiskMark 7 benchmark test showed that the sequential access performance of Intel SSD 665p was improved by 40-50% and random access by about 30%.

It should be pointed out that the drive runs for a short time and the hard disk is relatively empty, so these burst data can only be used as a reference for SLC cache speed.

However, after comparing the measured results of Intel SSD 660p, AnandTech points out that when the queue depth is high enough, sequential transmission can reach a similar 1.7 ≤ 1.8 GB/s, so the actual I ≤ O increase of 665p may be only about 20%.

As for the real performance of QLC flash after cache exhaustion and the consumer acceptance of QLC flash compared with TLC flash, it still needs time to test.

Finally, according to the close-up photos of 665p and 660p shared by Natan Kirsch of LegitReviews, it is known that there is little change in the PCB locally--it is still single-sided M22280 plate type, and only four NAND can form 2TB version.

Unfortunately, Intel has not yet disclosed the release date of 665p, but I believe we will only have to wait a few months. In terms of price, it should be on par with the 660p sequence and even become one of the most affordable NVMe SSDs on the market.
