As our testing revealed, Samsung's 970 Pro 1TB is without question the best performing flash-based consumer SSD you can buy at this time and likely will remain so for the foreseeable future.
The advantage that 2-bit flash has over 3-bit manifests itself most when running workloads where data is not being read from a caching layer. When data is not being read from a 3-bit drive's caching layer, which is almost always the case when running a real-world type workload, 2-bit flash performs much better than 3-bit.
When running synthetic workloads, drives that have an SLC buffer are reading back data that was just written and still resides in the fast caching layer. This is why synthetic benchmarks always write data before they read data. This means that random read performance as shown by synthetic benchmarks is typically inflated in an unrealistic manner.
When we run real-world type tests, data is being read from a drives flash array outside of its SLC buffer. When an SSD has an SLC cache, it may deliver earthshattering synthetic performance, but then underperform by comparison when running workloads. Samsung's 970 Pro doesn't have a caching layer, so workload performance is more inline with synthetic results than we see from drives that use caching.
When Samsung launched their 970 Series back in April, the 970 Pro 1TB came tagged with an MSRP of 649.99. However, Samsung has since revised their suggested pricing for the 970 Series significantly. Now the 970 Pro 1TB carries a considerably lower MSRP of $499.99. Some retailers haven't yet adjusted pricing to reflect this change, but we have seen a few retailers selling the 970 Pro 1TB at its new MSRP.
With its new lower MSRP, we believe the 970 Pro presents a great value proposition for the consumer. It's not that much more expensive than many of the top performing TLC-based NVMe SSDs currently on the market. We believe that when you really dig down and compare what the 970 Pro has to offer, it is actually the better value in most cases for the following reasons:
A 970 Pro gives you more useable capacity than a typical TLC-based SSD. 1TB class TLC SSDs give you at most 1000GB of raw user capacity; some only 960GB. The 970 Pro 1TB gives you a full terabyte or 1024GB of raw user capacity. That's 24-64GB more raw capacity for the end-user. The 970 Pro outperforms its TLC counterparts. And finally, the 970 Pro offers double the endurance of its TLC-based counterparts.
Because TweakTown tests SSDs with the drive running as our system (OS) disk we are in a relatively unique position to comment on what matters most - actual user experience. The user experience delivered Samsung's 970 Pro is outstanding. Everything about the way our system performs when powered by Samsung's 970 Pro is the best we've experienced from a flash-based SSD. Samsung's 1TB 970 Pro is 100% TweakTown recommended.
