Number of games based on a 36GB average per game. The number of games will vary based on file size, formatting, other programs, and factors. Also of interest are two of the most premium SSDs from the PCIe 3.0 era: the 1.5TB Intel Optane SSD 905P and the Samsung 970 PRO. The 970 PRO was the last high-end consumer drive to use MLC NAND, which gave it a significant advantage on heavy, long-running storage workloads as compared with TLC SSDs that use SLC caching to provide improved peak performance. The 970 PRO is old enough that newer, faster TLC NAND is catching up even in tests where MLC used to be a major advantage—and of course the latest and greatest TLC drives with PCIe 4.0 have far higher peak performance. Intel Optane SSD 905P Considering that Western Digital (WD) is a business built on mechanical drive storage, those running it have made an impressively smooth transition to solid-state solutions, with many of its SSDs being highly popular. Intel’s upcoming Z590 motherboards and some Z490 motherboards paired with the latest 11th Gen Intel Core CPUs will also support Gen4 SSDs. Again, you can install this on a PCIe 3.0 M.2 slot, but the speed will be limited to around 30Gbps. Below are the specifications of the system I used to test the 980 PRO 2TB capacity.

Yes, it really comes down to pricing. Specs sheet might show a somewhat substantial difference, but based on actual day to day use, it’s really hard to tell the difference.I just bought a 2TB 980 Pro. Yes the SN850 is a tiny bit faster but it was also a fair bit more expensive in my market. I had also read someone having issues with it when it was connected through the chipset. If money was no object I would have gone the Corsair MP600 Pro as it looked the best to me but had a price to match which wasn’t worth it for the small gain over the 980 Pro. Reply Those with an existing PCIe 3.0 system should consider a cheaper SSD than the SN850, as relatively soon systems with PCIe 5.0 or 6.0 will become available.

That enhanced version not only offers superior cooling but also has some programable LED lighting on it that can be controlled by a Windows application if you run that OS. Specs & Features abufrejoval - Thursday, March 18, 2021 - link Somehow I think that I'll never be able to recover in the faster response times of this drive the time it would take me to swap it against the 980 Pro I currently have in my Ryzen 5800X workstation... Both the 980 Pro and SN850 are excellent Gen4 SSDs. You can’t go wrong with any of these drives. However, with a Samsung SSD, you can take advantage of the company’s proprietary software; like the Magician and Data Migration. Samsung’s Magician software is simply well polished and ahead of its competition. WD also has an SSD tool kit, called the WD Dashboard. But WD doesn’t have proprietary migration software.Looking at the results above, this tells us that there’s not a huge difference between all of the Gen4 SSDs. Their storage scores are very close; although the 980 Pro 2TB seems to fall behind when it comes to its storage bandwidth. I ran the benchmark a couple of times, but the results were very similar. PCMark 10 Full System Drive Benchmark Results It’s heartening to see this level of competition in the NVMe market, and I hope it continues unabated when quad-plane NAND arrives to push these devices towards the very limits of PCIe 4.0 throughput and beyond with PCIe 5.0. Price However, in fact, the performance of PCIe 4.0 SSDs released in 2019 were never better than 5,000 MB/s for reads, 4,400 MB/s for writes. This is only 42% better than the previous PCIe 3.0 SSD’s 3,500 MB/s performance even though the bandwidth doubled. Samsung’s answer to this is the 980 PRO, which features up to 7,000 MB/s for reads and up to 5,000 MB/s for writes.” So any proper NVMe is certainly good and already Phison E16 based 5GB/s drives with their now closer to PCIe v3 drives price would go long way to future normal user/gamer. All these capacities offer 7,000MB/s read speed, but write performance varies from 4,100MB/s for the smallest drive to 5,100MB/s for the largest (2TB) option. Interestingly, the best write performance available is with the 1TB unit that can potentially achieve 5,300MB/s writes.

In this test, the Samsung 980 Pro 2TB outperformed the SN850 in the sequential test. However, both newer Gen4 drives performed poorly during the sequential write workloads. Although, it wasn’t the case when it comes to the 4KB random workloads. Both the 980 Pro and SN850 performed well; with a read and write speeds of above 2,000MB/s. PCMark 8 Storage Benchmark Results Take advantage of irrational PCIe® Gen4 NVMe™ speeds up to 7000MB/s 2 read and 5300MB/s 2 write (1TB model) for a responsive and seamless gaming experience. Before we start comparing both drives, allow me to discuss a little bit about the Samsung 980 PRO 2TB capacity first. The Samsung 980 Pro SSD series features a new Elpis controller that can process 128 I/O queues simultaneously. It is about four times that of the previous Phoenix controller used in the 970 Pro and EVO Plus. Popular Now: Nintendo 64 classic Perfect Dark ported to PC, playable in 4K 60 FPS with keyboard and mouse MB/s = 1 million bytes per second. Based on internal testing; performance may vary depending upon host device, usage conditions, drive capacity, and other factors.
Alongside those solutions, new NVMe storage designs will appear to exploit the increased throughput that these interfaces will allow, even if the SN850 is likely to be supported on them. Performance

The drive is available in two versions, a bare drive that I received from WD for review or an alternative version that has an attached heatsink. The Samsung 980 Pro SSD is a PCIe 4.0 Gen4 SSD; meaning the older generation or system may not support this drive. The only system that currently supports this type of SSD is an AMD X570 or B550 motherboard; powered by (at least) an AMD Ryzen 3000 CPU. Of course, the latest Ryzen Threadripper supports them as well.Differences in TBW (total bytes written) are down to the raw capacity and the number of times each location on the drive is written to. Larger drives have each part of the flash written to fewer times for the same amount of use. What’s challenging to quantify is that these numbers are heavily influenced by cache memory since Flash modules won’t operate at this performance level. Space you don’t have doesn’t have any speed… Except maybe to minus direction, because after running out of space you need to uninstall game/remove something to install new game. Reply Like its smaller sibling, the 2TB SN850 is among the best gaming SSDs ever made. Real-World Testing: PCMark 10 Storage Tests
