Lexar introduces NM800 SSDs, feature read/write speeds of up to 7.4GB/s and a graphene heat spreader.
Lexar has announced a new series of M.2 solid-state drives (SSDs). The Lexar Professional NM800 drives are capable of sequential read and write rates of up to 7.4 and 5.8GB/s, respectively, depending on the model and configuration. In addition, graphene is used to create a thin heat spreader for the SSDs.
The Lexar Professional NM800 will be available in M.2 2280 format and will be available in 512GB and 1TB storage configurations. The SSDs are equipped with tlc-nand and are connected to a PCIe 4.0 x4 interface using an undisclosed NVMe 1.4 controller.
The sequential read and write rates of the 1TB model reach up to 7.4GB/s and 5.8GB/s, respectively. The random read speed is 450,000 iops, while the random write speed is a maximum of 750,000 iops, with the random read speed being the fastest. The 512GB variant has slower sequential read and write capabilities, with a sequential read speed of 7GB/s and a sequential write speed of 3GB/s for the 512GB model. The random read and write rates of the 512GB model are 200,000 and 550,000 iops, respectively, according to the manufacturer.
According to Lexar, the endurance is a maximum of 500TBW with a mean time between failures of 1.5 million hours and 0.44 drive writes per day. The 512GB model has a suggested retail price of 100 euros, while the 1TB model has a suggested retail price of 180 euros.

throwing it out there because why not, I'm running 1x pcie 4.0 nvme 1x pcie 3.0 nvme 6x sata ssds
other than the use of copying large and only large files between the two nvmes everything else works better with regular sata ssds
5-7gb/s where with what ? small files copy is still very slow my ssd often do better
I managed to get 1Gb/s copying a 27gbs file from my 10gbit server to a nvme but that's the odd case, for everything else, gaming downloading etc...a regular ssd works better, not the same..better
nvme drives are borderline a scam those speeds you will never see outside of maybe very specific professionnal use and that's all they talk about

not going to pick nits as we all have different crap of variable file sizes on our storage.
but there is a definite use case that justifies most usage and that's physical size.
i do regularly copy massive files (esp. back-ups - the cloud is useless in a service interruption) and a folder is often 15 Gb. and relevant to gaming i do not want to schedule my internet. the advent of on-pcb nvme means my back-up is on my mobo. and that's the fastest you will ever be able to transfer files - between on-board drives, which you just cannot do with a 2.5"/3.5" RAID array (where often the price of the array is greater. but i concede the array is larger volume sizes).
so that's i guess is picking nits after all
. but if you have the time and space to fit your gear, you are right for the daily life of the majority of people.

@kakiharaFRS i can not talk about slower than sata and what not , but moving from an intel 330 ancient ssd 120 gb to a 250gb evo literally noticed no difference nothing i could tell other than that my os drive have a lot more space . Either way it is benched over and over again that any ssd will do just fine for daily tasks . Putting timers up to be able to measure 0 to 2 sec gain in the majority of the time does not even matter . Waiting to see what the direct storage will do until there is an actual reason for me to update i am in no rush to get nvme drives .... Hell by the time we finally see direct storage actually getting used i might be able to buy 2x the capacity for the same money compared to today :p
Ps. Obviously there are use cases that nvme ssds will benefit your workflow me and the majority of everyday users are not among em :p

Backing up my drive from one nvme to another is insanely fast.
That said, until we see DirectStorage in use with games and other programs, I'm holding off upgrading my drives any time soon.
