- Four DapuStor Roealsen6 R6060 drives now provide a full petabyte of storage
- Read speeds remain high, while write limitations become more apparent
- Fewer physical drives reduce rack space, power consumption and overall infrastructure complexity
Projections made in 2025 that SSD capacities could reach around 246TB by the end of 2025 are now coming true, with DapuStor’s latest drives living up to expectations.
The DapuStor Roealsen6 R6060 offers 245.76 TB of capacity in a single E1.L form factor and maintains the “doubling trend” moving from 61.44 TB to 122.88 TB and now to nearly 256 TB equivalents.
This scale means that only four such drives are required to reach one petabyte of storage space, profoundly changing how data centers approach physical space and infrastructure planning.

Petabyte-scale storage with fewer drives
The drive relies on PCIe Gen5 connectivity and a 16-channel controller that reaches up to 14,000 MB/s sequential read throughput and approximately 2.1 million IOPS for random reads.
These figures closely match measured results, suggesting that the advertised specifications are not exaggerated in this case.
However, the architecture relies on eQLC NAND and limited onboard DRAM, which introduces trade-offs that become more apparent as capacity increases.
This SSD is compatible with systems such as Ubuntu, Windows Server and VMware ESXi, which means it is aimed at deployment in large environments rather than individual use.
The Roealsen6 R6060 is primarily designed for read-intensive workloads, and this design choice shapes its overall behavior.
Sequential read performance slightly exceeds the official figures, reaching over 14,000 MB/s during testing, while sequential write speeds remain around 3,600 MB/s.
Random read operations also perform strongly, especially under 4K and 8K workloads where the drive delivers close to its rated limits.
However, the write performance does not scale in the same way. As capacity increases, the indirection device grows larger, reducing both endurance and write efficiency.
This limitation is recognized within the broader category of QLC-based enterprise storage, where fast retrieval takes priority over sustained write-heavy operations.
As a result, workloads involving frequent random writes are not the intended use and their performance appears to be relatively limited.
Despite the density of the E1.L form factor, thermal behavior remains relatively controlled under sustained workloads.
Tests show peak temperatures of around 51°C when using air cooling, suggesting that cooling requirements are manageable even under sustained stress conditions.
This is notable because compact enterprise drives often face thermal challenges that affect stability and performance consistency.
Since the high-capacity drive reduces the number of physical devices required in a rack, the total power consumption per petabyte be lower, which reduces costs.
The R6060 reflects a shift in enterprise storage priorities, where capacity and retrieval speed are more critical than balanced performance across all workloads.
