Title: Samsung Joins The 60 TB SSD Club, Looking Forward To 120 TB Drives

Multiple companies offer high-capacity SSDs, but until recently, only two
companies offered high-performance 60 TB-class drives with a PCIe interface:
Solidigm and Western Digital. As our colleagues from Blocks & Files
discovered, Samsung quietly rolled out its BM1743 61.44 TB solid-state drive
in mid-June and now envisions 120 TB-class SSDs based on the same platform.

Samsung's BM1743 61.44 TB features a proprietary controller and relies on
Samsung's 7th Generation V-NAND (3D NAND) QLC memory. Moreover, Samsung
believes that its 7th Gen V-NAND 'has the potential to accommodate up to
122.88 TB,'

Samsung plans to offer the BM1743 in two form factors: U.2 for PCIe 4.0 x4 to
address traditional servers and E3.S for PCIe 5.0 x4 interfaces to address
machines designed to offer maximum storage density. BM1743 can address
various applications, including AI training and inference, content delivery
networks, and read-intensive workloads. To that end, its write endurance is
0.26 drive writes per day (DWPD) over five years.

Regarding performance, Samsung's BM1743 is hardly a champion compared to high-
end drives for gaming machines and workstations. The drive can sustainably
achieve sequential read speeds of 7,200 MB/s and write speeds of 2,000 MB/s.
It can handle up to 1.6 million 4K random reads and 110,000 4K random writes
for random operations.

Power consumption details for the BM1743 have not been disclosed, though it
is expected to be high. Meanwhile, the drive's key selling point is its
massive storage density, which likely outweighs concerns over its absolute
power efficiency for intended applications, as a 60 TB SSD still consumes
less than multiple storage devices offering similar capacity and performance.

As noted above, Samsung's BM1743 61.44 TB faces limited competition in the
market, so its price will be quite high. For example, Solidigm's D5-P5336
61.44 TB SSD costs $6,905. Other companies, such as Kioxia, Micron, and SK
Hynix, have not yet introduced their 60TB-class SSDs, which gives Samsung and
Solidigm an edge for now.
