Samsung Introduces 61.44 TB BM1743 SSD with 176-Layer V-NAND
Samsung has introduced its latest BM1743 SSD, boasting an impressive 61.44 TB of storage capacity. The BM1743 utilizes Samsung's seventh-generation 3D NAND (V-NAND) technology, featuring 176 layers of memory cells. This represents a significant leap from its predecessor, the BM1733, which debuted in 2020 with 96-layer technology and a maximum capacity of 32 TB. Performance-wise, the BM1743 doesn't disappoint. It delivers up to 1.6 million random read IOPS and 110,000 random write IOPS, with sequential read and write speeds of 7.2 GB/s and 2.0 GB/s, respectively. These figures position the drive as a highly capable solution for read-intensive workloads. Samsung claims that the new SSD offers double the sequential read and write speeds of its fifth-generation technology, with random reads quadrupling in performance. This advancement suggests that quad-level cell (QLC) SSDs are now approaching the performance levels of their triple-level cell (TLC) counterparts while offering superior storage density.
The BM1743 is available in the traditional U.2 form factor, with an E3.S variant supporting PCIe Gen 5 also in the lineup, thanks to the custom Samsung controller. Samsung has enhanced the durability and data retention capabilities of the BM1743. The new drive boasts an improved endurance rating of 0.26 drive writes per day (DWPD) throughout its warranty period, a notable increase from the BM1733's 0.18 DWPD. Additionally, the BM1743 extends its power-off data retention to three months, tripling the one-month period of its predecessor. In a hint of things to come, Samsung has suggested that a 122.88 TB model may be on the horizon, potentially doubling the capacity of the BM1743. This new offering puts Samsung in direct competition with Solidigm's D5-P5336, which has dominated the high-capacity SSD market for the past year. High-density storage solutions are becoming more important as AI and HPC tasks require and produce massive amounts of data.

...and half of the lifespan of the TLCs, which is half of the lifespan of MLC, which is half of SLC...............

This drive features 0.26 DWPD while most enterprise TLC drives feature anywhere from 1 DWPD to 3 DWPD.
So you are getting anywhere from 1/4 to 1/16 of the endurance. I've seen ServeAtHome try to hand-wave the endurance of these large QLC drives off because their total endurance is very high (duh they are 60TB+) but that ignores the fact that, unless you aren't using the extra capacity, your writes scale up as your data needs scale up according to the ratio of read/writes for a given workload. If you are replacing two 30.72TB drives with one 61.44 TB drive for example, assuming the same use case, your writes on the 61.44 TB drive per day would be the combined total of your daily write of both your 30.72 TB drives. These drives are intended for extremely read heavy workloads and the amount of writes you place on a drive should be heavily kept in mind when purchasing them for your home lab / place of work.
It's also wise to point out that Read Disturb is a much bigger issue on QLC. Some drives try to allieviate this issue by storing frequently accessed data in the SLC but obviously that will only benefit certain workloads and the benefit depends on the SLC size. Read Disturb requires the rewriting of a block after a certain number of reads and thus makes QLCs issues regarding endurance more problematic.
QLC at this capacity, in this segment, is not that terrible. Same target customer as Solidigm D5-P5336. Despite all issues associated with QLC, enterprise grade NVMe has numerous tricks (extra circuitry) inside not found in consumer devices which ensure data integrity in demanding environment. Both models - even if QLC - will sell by the tonne given rapacious demand for storage in data center segment.

Yeap. Consumer drives sucks, when you switch to the industrial grade stuff you never going back to lousy M.2s. Owning stacks of Micron 7450 Pro/Max and they smoking.
It should also be noted that these higher capacity drives are really only for those who space is at an extreme premium as they typically end up being more expensive than if you just purchase more lower capacity drives. You can get four 15.36TB TLC drives for around the price and depending on what drive you snagged you'd be looking at 4x to 16x the endurance. For home lab users you'd also have to consider that anything above PCIe 3.0 is very had to get working via cable so you either have to have a server with PCIe 4.0 / 5.0 or use a carrier card (although I have yet to see a carrier card explicitly claim PCIe 5.0 support yet, only 4.0 so it's going to depend on your motherboard and how good signal quality is).
