According to news from this site on June 18, Samsung Semiconductor recently introduced its next-generation data center-grade solid-state drive BM1743 equipped with its latest QLC flash memory (v7) on its technology blog.
According to TrendForce in April, in the field of QLC data center-grade solid-state drives, only Samsung and Solidigm, a subsidiary of SK Hynix, which have been involved for many years, passed the enterprise customer verification at that time.
Compared with the previous generation v5 QLC V-NAND (note on this site: Samsung v6 V-NAND does not have QLC products), Samsung v7 QLC V-NAND flash memory has almost doubled the number of stacking layers, and the storage density has also increased Significant improvement.
At the same time, the sequential read and write performance of v7 QLC V-NAND is at least twice that of the previous one, and the random read speed has reached 4 times.
This means that BM1743 can provide far more capacity and performance than the previous generation data center QLC SSD BM1733a based on v5 QLC V-NAND, meeting the needs of data centers for better storage.
BM1743 includes two form factors: U.2 and E3.S. The U.2 version supports PCIe 4.0, has a capacity of up to 61.44TB, and has the potential to be further expanded to 122.88TB. The E3.S version can support PCIe 5.0.
For comparison, BM1733a only supports PCIe 3.0, and the maximum capacity is only 15.36TB, which is a quarter of 61.44TB.
In terms of reliability, the write endurance of BM1743 is 0.26DWPD and the power-off data retention time is 3 months; the two data of BM1733a are 0.18DWPD and 1 month respectively.
The specific performance of the 2.5-inch U.2 version of BM1743 is as follows:
Sequential reading | Sequential writing Input | Random read | Random write |
7200MB/s | 2000MB/s | 1600K IOPS | 110K IOPS |
Samsung Semiconductor stated that users can use BM1743 directly in the existing PCIe 3.0 environment and enjoy its lower TCO cost;
You can also make full use of the improvements brought by BM1743's support for PCIe 4.0 to reduce read task response time and improve AI load processing capabilities;
The BM1743 E3.S version supports PCIe 5.0 Support will bring greater performance advantages to the data center.
