Possibly up to double (480MB/sec) that soon for large sequential read workloads. Seagate has their multi-actuator Exos 2X14 Mach.2 drives which should start hitting some level of channel availability within the coming weeks.
For video editing, ETL and other read-heavy workloads, they have a point.
They are actually presented as two drives, so in order to benefit you have to overlay a RAID 0 or some other form of striping.
You've been out of the loop for a while. Certain HDDs have been able to achieve such speeds for about a decade, if not more. Most of their (slow) gains over the last 10 years have been in capacity.
Only takes you 8 days to read it, funny right? ;)
230MB/s, not 230Mbps; one day, not eight.
Yes, but that appears to be if you're doing sequential reads. Works for a handful of use cases, but not most normal desktop or server workloads.
Sounds ideal for large arrays for video post use. We used to string 16 drives together to get speeds of what a modern m.2 SSD can do as a single drive. Only, the arrays gave you the capacity to do useful things rather than the toy-like capacity of 2-4TB SSDs. Doubling the speed of spining rust might be interesting when building RAID-6 volumes for edit bays
But even if in "normal server workloads" it's comparable to older drive you still get the benefit during things like RAID recovery where it very much will be sequential operations dominating. So it's an improvement which can really matter for unlikely but very critical server operations.
I've also seen a lot more reasonably priced gear include 2.5gbit LAN, which is a good pairing if you're home rolling a NAS for example.
