You can see 0.6MB/s is the max for reading 4 kilobyte files.Īlso, if your speed begins with 1GB/s than that means your OS is buffering writing to RAM first. Speeds will drop the lower the file size, basically. HDDs are much slower when processing smaller files, since they have to seek. Remaining partition of the drives above, well now I know why I was having speed issues from this server now. OS : Windows Server 2003 Enterprise Edition SP2 (x86) Same model drives as before (barracuda 1.5TB) but in RAID 1 gigabyte mirror. (while streaming media, audio and 4 torrents lol), primary OS drive, single large partition Seagate Baracuda 1.5TB *2 in RAID 0 on X58 board using intel matrix raid. Western Digital 150GB Raptor (Old Version, not VelociRaptor)ĬrystalDiskMark 3.0 (C) 2007-2010 hiyohiyo Very solid scores for an AMD Ryzen 5 3600X system with no optimizations and a standard install of Windows 10.CrystalDiskMark 3.0 圆4 (C) 2007-2010 hiyohiyo CystalDiskMark:īenchmark Results: The Sabrent Rocket 4 Plus 2TB NVMe SSD came in with scores of 7,049 MB/s read and 6,831 MB/s write on CrystalDiskMark 7! The Random 4K performance at QD1 was 70 MB/s read and 243 MB/s write. Note that CDM only supports Native Command Queuing (NCQ) with a queue depth of 32 (as noted) and shows the highest score of five runs. These are amazing speeds and we are finally seeing the true potential of PCIe Gen 4 drives!ĬrystalDiskMark is a small benchmark utility for drives and enables rapid measurement of sequential and random read/write speeds.
ATTO Disk Benchmark:īenchmark Results: On ATTO Disk Benchmark we found that the Sabrent Rocket 4 PLUS SSD topped out at 6.17 GB/s write and 6.94GB/s read at the standard queue depth of 4. The test was run with the default runs of 0.5KB through 64MB transfer sizes with the total length being 256MB. It measures raw transfer rates for both reads and writes and places the data into graphs that can be very easily interpreted. ATTO measures transfers across a specific volume length. ATTO is one of the oldest drive benchmarks still being used today and is still very relevant in the SSD world.
