Write performance basically does not change. As you can see, performance in throughput, IOPS, and latency drastically improves as the file is continuously read. Below are tests using 3, 6, and 9 passes. I was only able to obtain one of these for a reasonable price. Basically, if a file is read over and over again, it is moved to the SSD cache (providing it fits of course).

It uses similar technology as Seagate’s consumer SSHDs, but with a much faster (but smaller) platter. 3 passes, 1GiB each (unless otherwise specified).

Software RAID0 and RAID1 were created using the native disk management tool with all default options.I may test this is the future with a different file system. This means that numbers that you see here may differ from manufacturer specifications by quite a bit.Īt this time, Windows does not support dual port for multi-read/write, only for fail-over. These tests were not conducted with dual port, only single port.SAS dual port allows for fail-over should a cable or port die, as well as increased throughput should the software support it.

Awhile back, I made a video about USBc and the classic Mac Pro but lamented yet ago the terrible benchmarking on macOS. To use SAS dual port, two cables must be connected to the HDD via the backplane, or in case of an expander type backplane, the technology must be supported. AmorphousDiskMark is CrystalDiskMark for macOS lets all stop using BlackMagic Disk Speed Test and AJA Disk Test Benchmarking a MacBook Air M1s SSD.

Most of these models feature SAS dual port technology.

This is about double the width of consumer 2.5' SSD, so make sure they will fit where you want to use them. Even if there is a performance increase, the increase in cost probably won’t be worth it. I highly doubt there will be any serious performance increase from a SAS3 HBA over the SAS2 model tested. Provided you have a similar setup as I do, results should be comparable. Generally speaking, I/O uses very little CPU even with basic software RAID0/1.

If there’s a specific model that you would like me to test with the same methodology, feel free to leave a comment below and I’ll do my best. If I am able to test more models, I will add them to the list. This is not a definitive list of 2.5' SAS HDDs, of course. The drives were well packaged and out of 20+ drives, I had zero DOA. Popular enough to come up in many tests and reviews online so it is always easy to google up results for comparison.Most of the drives listed below were provided to me by bitdeals.tech, special thanks to the guys there for providing a pair of each for RAID 0 and RAID 1 testing.

Straightforward and user-friendly app, open source, portable version available. It could use more complex interface, capable of testing several drives and showing them side by side. I found no explanations how are they scaled so for me they are more confusing than helpful. Features Measure sequential reads/writes speed Measure random 512KB, 4KB, 4KB. Downsidesīackground graphs are not to scale. CrystalDiskMark is a disk benchmark software designed to quickly test the performance of your hard drives. Text report can be copied to clipboard from menu ( Edit > Copy) and additionally includes IOPS values. Very easy to use (just hit All button to run tests), single-screen interface, easy to interpret results.

Test data size defaults to 1GB with recommendation to lower for slow drives (such as generic flash drives). It uses both sequential and random (with different block sizes) tests. What it doesĪpp performs number of repeated tests (five by default) on selected drive partition and reports read and write performance. It tests drives for read and write speeds. I had previously posted about CrystalDiskInfo and this one is another utility from same developer. I recently had few conversations on Twitter with Viper007Bond about SSDs (I totally dig my Kingston one) and CrystalDiskMark came up as benchmark tool.
