FMS: Samsung launches fast and large data center SSDs
Samsung's latest QLC SSD holds a whopping 128 TByte. Another new SSD tops all data center SSDs in terms of IOPS performance.
The Samsung SSDs come in a 2.5-inch housing. However, if you want to spend a fortune and install them in a desktop PC, you will need a U.2 adapter.

Samsung presented two new SSDs at the FMS storage media trade fair: PM1753 and BM1743. The BM1743 holds a whopping 128 TByte and is thus on a par with the SSD announcement from Western Digital. Samsung uses memory chips that write four bits per cell (Quadruple Level Cells, QLC). The manufacturer promises 7.5 GByte/s when reading large files and 3.5 GByte/s when writing. The speed when accessing random addresses also differs greatly: 1.6 million IOPS when reading, only 45,000 when writing. The latter value is lower than that of conventional SATA SSDs; the data carrier is therefore not intended for many rewrites. The BM1743 is only available in a 2.5-inch housing with a U.2 connection. Compared to previous QLC SSDs, Samsung has reduced the idle consumption: the SSD requires 5 watts, in later versions the SSD should even only consume 2 watts.
The new PM1753, Samsung's second PCIe 5.0 SSD for data centers, is significantly faster. It achieves 14.8 GByte/s when reading and 11 GByte/s when writing. Samsung promises 3.4 million IOPS, which puts it just above the new SSDs from Micron and Solidigm. It still achieves 600,000 IOPS when writing; further details, such as endurance, are not yet available.
The capacity of the PM1753 is a maximum of 32 TByte; it is also available in a U.2 housing, but also in the enterprise format E3.S. Samsung also claims to have reduced the power consumption of the PM1753, but does not specify any values.
Petabyte SSD still a long way off
The SSD with the legendary capacity of one petabyte mentioned by Samsung some time ago does not yet seem to have disappeared from the Korean company's mind: Samsung once again showed a slide with this value on it. However, underneath it was the year 2035, so it will still take some time. However, capacity increases are planned: An SSD with 256 TByte will follow between 2024 and 2026; 512 TByte are marked for the years 2027 to 2029. However, these will not find their way into desktop PCs or notebooks because they are planned in the EDSFF-E3.L data center format. According to this slide, you will have to wait at least until 2027 for an M.2 SSD with 16 TByte from Samsung. Other manufacturers are much faster.
