SSDs have no appreciable seek time and have much faster read rates that spinning rust. Depending upon how much onboard RAM cache they provide (some even provide no cache), you may also see considerably better burst write speed, although sustained write speeds are generally no better than a disk.
Hard disk drives usually write sequentially at around 130MB/s. I've seen QLC drives that aren't better than HDD, but unless you're buying literally the slowest drives on the market, SSDs will probably write *much* faster than HDD.
P.S: Why are you using a RAID-0 array? You have no redundancy, higher software complexity, somewhat better read speeds and much slower write speeds
Most RAID levels will have slower writes than single disks for some workload (usually small random writes on arrays with small numbers of members). RAID0 is the only level I'd expect to be faster than a single disk for all workloads.
When would you see much slower write speeds with RAID0? _______________________________________________ users mailing list -- users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to users-leave@xxxxxxxxxxxxxxxxxxxxxxx Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/users@xxxxxxxxxxxxxxxxxxxxxxx Do not reply to spam on the list, report it: https://pagure.io/fedora-infrastructure
