- 4 DapuStor Roealsen6 R6060 drives now ship a full petabyte of storage
- Learn speeds stay sturdy whereas write limitations turn into extra obvious
- Fewer bodily drives cut back rack house, energy consumption, and general infrastructure complexity
Projections made in 2025 that SSD capacities may attain round 246TB by the tip of 2025 at the moment are materializing, with DapuStor’s newest drive assembly expectations.
The DapuStor Roealsen6 R6060 gives 245.76TB capability in a single E1.L kind issue and sustains the “doubling pattern” transferring from 61.44TB to 122.88TB and now to just about 256TB equivalents.
This scale means solely 4 such drives are required to achieve a petabyte of storage, which drastically alters how knowledge facilities strategy bodily house and infrastructure planning.

Petabyte-scale storage with fewer drives
The drive depends on PCIe Gen5 connectivity and a 16-channel controller, reaching as much as 14,000MB/s sequential learn throughput and roughly 2.1 million IOPS for random reads.
These figures align intently with measured outcomes, suggesting that the marketed specs will not be exaggerated on this case.
Nevertheless, the structure is dependent upon eQLC NAND and restricted onboard DRAM, which introduces trade-offs that turn into extra seen as capability will increase.
This SSD is appropriate with programs equivalent to Ubuntu, Home windows Server, and VMware ESXi, which suggests that it targets deployment in large-scale environments relatively than particular person use.
The Roealsen6 R6060 is designed primarily for read-intensive workloads, and this design alternative shapes its general conduct.
Sequential learn efficiency barely exceeds official figures, reaching over 14,000MB/s throughout testing, whereas sequential write speeds stay round 3,600MB/s.
Random learn operations additionally carry out strongly, significantly beneath 4K and 8K workloads, the place the drive delivers close to its rated limits.
What to learn subsequent
Write efficiency, nevertheless, doesn’t scale in the identical method. As capability will increase, the indirection unit grows bigger, which reduces each endurance and write effectivity.
This limitation is acknowledged inside the broader class of QLC-based enterprise storage, the place quick retrieval takes precedence over sustained write-heavy operations.
Because of this, workloads involving frequent random writes will not be the meant use case, and their efficiency seems comparatively constrained.
Regardless of the density of the E1.L kind issue, thermal conduct stays comparatively managed beneath sustained workloads.
Testing reveals peak temperatures of about 51°C utilizing air cooling, which means that cooling necessities are manageable even beneath steady stress situations.
That is notable as a result of compact enterprise drives usually face thermal challenges that have an effect on stability and efficiency consistency.
Because the high-capacity drive reduces the variety of bodily models required in a rack, complete energy consumption per petabyte can be decrease, lowering value.
The R6060 displays a shift in enterprise storage priorities, the place capability and retrieval pace are extra crucial than balanced efficiency throughout all workloads.
