Transcend Announces MTE240S PCIe Gen4 M.2 NVMe SSD

Transcend today announced the MTE240S, a mid-range SSD built in the M.2-2280 form-factor, with PCI-Express 4.0 x4 host interface, which boasts of some stellar manufacturer-rated endurance numbers. The drive uses an unknown 4-channel controller, and while its rated sequential speeds fall well below what the bus is capable of, they're higher than most PCIe Gen3 drives. The MTE240S is available in 500 GB and 1 TB capacity variants. Both come with graphene-coated copper heatspreaders.

The 500 GB variant offers sequential speeds of up to 3800 MB/s reads, with up to 2800 MB/s sequential writes, up to 190,000 IOPS 4K random-reads, and up to 540,000 IOPS 4K random-writes. The 1 TB variant, on the other hand, clocks up to 3800 MB/s sequential reads, with up to 3200 MB/s sequential writes; up to 370,000 IOPS 4K random-reads, and up to 560,000 IOPS 4K random-writes. Transcend claims that the 500 GB variant can handle 850 TBW endurance, and the 1 TB variant 1,700 TBW. The company is backing them with 5-year warranties.

500GB with TBW 850T ? damn.price will be double. best NVMes are like 350~480T.

No best are 600TBW+Ironicly from Transcend themselves: geizhals.eu/?cat=hdssd&xf=2028_512%7E252_500%7E4832_3%7E4930_1000
~1.1PB for 500GB. I wonder what they're doing to achieve those number on a 500GB TLC drive. Im guessing massive spare area (overprovisioning).

Also it's likely using a 4 channel controller looking at the slow (for Gen4) speeds. Kind of defeats the whole purpose of using a Gen4 interface if they are using a 4 channel (instead of 8 channel) controller.

Likely they bought the "unknown"controller 2nd hand. :p
