The latest version of Samsung's firmware (available via Samsung Magician) fixes this bug, but it does leave a sour taste in my mouth. Initial firmware versions had a crippling bug that caused drive health to deteriorate much quicker than normal, something that also happened on the 980 Pro. The only point against the 990 Pro, besides the lack of higher capacity models, is the firmware. Other PCIe 4.0 drives have most of the 990 Pro's sequential and random performance for $100 or less. The 990 Pro's better sequential performance isn't really going to help in games, web browsing, and most productivity applications. For instance, the 1TB model of the 970 EVO Plus, one of our favorite M.2 SSDs, excels in the kinds of tasks and operations that users encounter the most in regular usage. That being said, there are cheaper SSDs, and what the 990 Pro is good at can be done by much less expensive and older drives. Samsung's 990 Pro is a great choice for people who know they're going to be encountering large files daily and need to access them or move them. By default, both SSDs transferred data in increasingly larger chunks, starting with 512 bytes and ending at 64MB, but both drives hit their limit once they got to the 1MB mark. Powered by a new Elpsis controller designed to harmonize the flash memory components and the interface for superior speed with a PCIe 4.0 interface that’s 2x faster than PCIe 3.0 SSDs and 12x faster than Samsung SATA SSDs every component of this NVMe SSD is manufactured by Samsung for performance that lasts. The other benchmark we're looking at is ATTO Disk Benchmark, which is useful for demonstrating how quickly SSDs can transfer data when under size limitations. It looks like Samsung already perfected or nearly perfected performance for these kinds of workloads a while ago. Target Drive: You can check partition information which will be cloned to target drive. Source Drive: You can check partition information which can be cloned from source drive. With a limited thread count, even high queue depth random reads and writes are roughly even. With the Data Migration, you can easily migrate your current operating system, application software, and user data to your new Samsung SSD. It's a different story in random performance, with the 990 Pro only seeing a significant advantage when multiple threads come into play. When transferring large files, the 990 Pro is almost twice as fast as the 970 EVO Plus. ![]() However, it's unlikely you'll run into many modern applications where SSD performance actually matters but the queue depth is only one or two. In sequential workloads, the 990 Pro significantly outpaced the 970 EVO Plus in both reads and writes, but when the queue depth is low, you'll see a slight gap in reads. Scores are organized by read/write and are measured in MB/s.
