KLEVV CRAS C920 Gen 4 2TB NVMe M.2 SSD
In order to meet the popularization of PCIe 4.0 technology, KLEVV launched a new CRAS C920 Gen 4 NVMe M.2 SSD product, using PHISON PS5018-E18 main controller, with 64 Layer Micron 3D TLC NAND particles, which can provide up to 7GB/s Read, 6.85GB/ s Write continuous reading and writing capabilities, 4K IOPS can reach more than 1,000,000, with Acronois True Image HD data migration software attached to the product, the original factory provides a 5-year maintenance service, with 1TB and 2TB capacity to choose from.
As a high-end PC brand of a subsidiary of South Korea’s SK Group, KLEVV is very aggressive in attacking the SSD market and has achieved good results. CRAS C920 is the company’s first Gen4 SSD product, using PHISON’s second-generation Gen 4 solution, with Micron 3D TLC NAND Flash, since most motherboards have M.2 SSD heat sink design, CRAS C920 does not have a pre-loaded heat sink, which actually saves the trouble and risk of removing the heat sink.
This time I received the test from the manufacturer as a 2TB version, model “K02TBM2SP0-C92”, using M.2 2280 Form Factor, PCI Express 4.0 x 4 transmission interface, supporting NVMe 1.4 transmission specifications, compatible with Ryzen 3000/5000 series processing The processor and Intel’s 11th generation Core processor platform have a TBW write life of 1,400 TBW.
PHISON PS5018-E18 controller
KLEVV CRAS C920 upgrades a new generation of PHISON PS5018-E18 controller, adopts TSMC 12nm process, built-in 32bit ARM Cortex R5 triple-core processor and dual CoXProcessor processors, with 8 Channel, 32CE data transmission channels, each Channel can be up to speed Up to 1,600 MT/s, it brings an amazing 7GB/s read and write bandwidth and 1 million-level IOPS performance, with the 4th generation LDPC error correction engine, and powerful error correction code technology to improve data reliability.
Micron 96-Layers 3D QLC NAND particles
In terms of NAND Flash, the KLEVV CRAS C920 2TB version provides a total of 8 Micron IA7BG64AIA 3D TLC NAND particles on the front and back of the PCB, with 96 Layers, a single 256GB capacity, using BGA lead-free, halogen-free packaging, supporting 3.3V Toggle 3.0 mode, in total 2TB capacity, the available space for formatting NTFS is 1,907.73GB.
There are 2 SK Hynix H5AN8G8NBJR-UHC DDR4-2400 1GB memory particles on board, a total of 2GB cache capacity, which can be used to store FTL data and cache, which can effectively increase the speed of reading and writing. In addition, random write data is processed by the SLC block. It can provide fast response time similar to SLC SSD, and continuous writing is directly passed to the TLC block.
ATTO Disk Benchmark test:
ATTO Disk Benchmark is a disk performance testing tool launched by ATTO company. The test uses 256MB of data size and increases the data size to 64MB in multiples of 0.5K, 1K, and 2K to test the impact of different file sizes on the speed of disk writing , The test results are expressed in bar graphs It uses sequential writing to test the best read and write capabilities of disks. It is a theoretical benchmark test that currently marks the highest performance of products in the industry.
According to the test results, the maximum read speed of the KLEVV CRAS C920 2TB version is about 6.64GB/s, and the write speed is 6.31GB/s, which is close to the performance specifications.
CrystalDiskMark test:
CrystalDiskMark is a set of disk testing programs developed by Japanese Hiyohiyo. It provides continuous disk read and write speed test and 4K random multiplex read and write performance test with different queue depth (Queue Depth).
Tested by CrystalDiskMark 8.0.2 version, the continuous read and write Q8T1 speeds of the KLEVV CRAS C920 2TB version are 7,025.23 MB/s Read and 6,756.45 MB/s Write; 128K continuous read and write Q32T1 speeds are 7,108.41 MB/s Read, 6,757.42 MB/ s Write; 4K Q32T1 random multiplex read and write speeds are 2,702.52 MB/s Read, 5,581.86 MB/s Write; 4K Q1T1 random multiplex read and write speeds are 77.87 MB/s Read, 384.22 MB/s Write.
AS SSD Benchmark test:
AS SSD Benchmark is also one of the main benchmarks for testing SSDs in the industry. On the premise that system memory acceleration is not used, it tests the read and write performance and speed of all aspects of SSDs by measuring reading and writing large files of 1GB.
The KLEVV CRAS C920 2TB version has a performance benchmark score of 11,355 in the AS SSD Benchmark, of which the read performance score is 3,577, the write performance score is 5,932, and the 4K random read and write performance with a queue depth of 64 is 2,992.99 MB/s Read And 5,111.59MB/s Write.
Set up Copy-Benchmark to simulate file copying under different conditions. In the “ISO” test, two large ISO image files will be copied to the test target; in the “Program” test, a large number of random size files will be written Fragmented files, simulating a typical program folder usually contains many small files; in the “Game” test, a large file and a small amount of fragmented files are written, and the simulated game folder usually contains a large game body file and some small files. Material files, etc.
The results showed that the write speed of simulated copying ISO image files reached 2,258.35 MB/s, the speed of simulated copying of typical program folders was 2,113.30MB/s, and the speed of simulated copying of game folders was also 3,259.45 MB/s.
Anvil’s Storage Utilities test:
Anvil’s Storage Benchmark is a set of professional disk performance testing software. It has a built-in IO Threaded test program, which can analyze the IO performance of disk 4K 32 queue depth in multiple read, write, and mixed read and write.
In terms of IOPS performance, 4K QD128 Read recorded 589,492.6 IOPS, 4K QD64 Write recorded 946.917.0 IOPS, 4K QD64 Read/Write mixed read and write recorded 1,171,347 IOPS, and finally scored 25,482.55 points in Anvil’s Storage Benchmark test results.
PCMark 10 Storage test:
The PCMark 10 Storage test simulates the speed of reading and writing program software, art software, games and other programs on a computer storage device, and can reflect the performance of opening programs or archiving in real use.
In the PCMark 10 Storage test, the KLEVV CRAS C920 2TB version scored 2,612. After combining different usage scenarios, its average Bandwidth was 429.45 MB/s.
