When it comes to performance with client SSDs, Samsung has been leading the market for years, but the company is somewhat behind its rivals with PCIe 4.0 drives. At the CES 2020 trade show, Samsung showcased its first PCIe Gen 4 drive — the 980 Pro — but it has yet to start commercial shipments. Last week the company published (opens in new tab) specifications of the drive at one of its websites (which have now been removed), an indication that the product is about to be launched.
Samsung's 980 Pro drives feature quite impressive performance. The company promises up to 7,000 MB/s sequential read speeds as well as up to 5,000 MB/s sequential write speeds. As far as random performance, we are dealing with SSDs capable of up to 1,000,000 random reads (4 KB, QD32) as well as up to 600,000 IOPS random writes (4 KB, QD1) for the 250 GB model, the 500 GB, 1 TB and 2 TB models are up to 1,000,000 IOP. To put the number into context: competing SSDs featuring a PCIe 4.0 x4 interface often have read speeds of up to 5,000 MB/s.
The Samsung 980 Pro SSD is based on the company's proprietary controller and uses the company's 3D TLC V-NAND memory (which Samsung calls 3-bit MLC V-NAND). The drive comes in an M.2-2280 form-factor and features a PCIe 4.0 x4 interface. Current capacities consist of 250 GB, 500 GB, 1 TB and 2 TB versions.
The controller supports AES 256-bit encryption as well as TCG/Opal IEEE 1667 coding, so the drive can be adopted for PCs used by enterprises and government agencies that require advanced security. Power consumption for the Samsung 980 Pro is is rated at up to 8.9 Watts peak, but on average the drive's power consumption is about 6.2 Watts.
One of the things that has an important impact on performance of modern SSDs is proper thermal management of the controller. To that end, high-end drives for gaming PCs come with heat spreaders that may prevent their installation into laptops. Samsung's 980 PRO drives feature a nickel-coated controller to manage its heat levels and ensure consistent performance. Furthermore, the SSD also comes with a heat spreading label based on graphene.
Samsung's publication on its Singapore website does not reveal pricing or ETA dates of the 980 Pro SSDs. Companies in general hardly ever publish information about their products well before their actual release dates. To that end, it makes a perfect sense to expect Samsung's 980 Pro drives to be released shortly.
As usual for Samsung's Pro drives, the 980 Pro models are covered by a five-year limited warranty. The company declares an endurance rating of up to 600 TBW (terabytes written) for its 980 Pro 1TB drive, and 300 TBW for the 500GB model, which is half the endurance of the previous generation 970 Pro SSDs.

250GB = €99
500GB = €169
1TB = €249
I'm really disappointed with them pushing TLC into Pro lineup.
If I look to put in a second m2 drive in my system it will be something based on the Phison E18 controller.
Possible maybe the bottleneck in bootup is more windows than the NAND.
How much of a difference does an Optane drive make on bootup which is suppose to be much faster?
I will wait for Intel Optane PCIEGen4 SSD and see .
What is the max TBW you've personally seen on any of your solid state drives?
