SSD Shatters Speed Records with Compression
27 Jan
Summary
- Drive delivers record sequential and mixed workload throughput with compression.
- Compression system reaches up to a 4:1 ratio, boosting usable capacity.
- SSD achieved 14,200MB/s sequential writes and 15,050MB/s reads.
The DapuStor Roealsen6 R6101C 7.68TB SSD is setting new benchmarks in storage performance, leveraging an integrated hardware compression engine. This drive, built with DapuStor's in-house DP800 controller and firmware, utilizes a PCIe 5.0 interface and 3D eTLC NAND flash, supporting the NVMe 2.0 protocol.
Paired with an application processor, the transparent compression engine reduces the amount of data written to flash. Under ideal conditions, this system can achieve up to a 4:1 compression ratio. Performance metrics include sequential write speeds of 14,200MB/s and read speeds of 15,050MB/s at a 2:1 compression level.
Random write performance also reached impressive levels, with results around 1.27 million IOPS in 4K workloads at the same compression ratio. The drive operates at approximately 18W under load, features a U.2 form factor, and is rated for 1 DWPD, compatible with common enterprise platforms.
While compression-based SSDs are not entirely new, the Roealsen6 R6101C offers enhanced capabilities. Reviewers noted that real-world results are contingent on the data's compressibility, but the drive has delivered the highest sequential and mixed workload throughput encountered from a flash-based SSD.
