Seagate's Mozaic 4+ platform uses 10 platters with up to 4+ TB capacity per platter to enable drives of up to 44TB. The drives are believed to feature a 7200 RPM spindle speed as well as conventional magnetic recording (CMR) and therefore offer predictably high performance by HDD standards: think sustained data transfer rates of around 300 MB/s, though we are speculating. Normally, Seagate and other makers of HDDs tend to release a lineup of hard drives offering different capacity points upon formal launch. With its Mozaic 4+ platform, Seagate is changing its tactics and only formally introduce its 44TB HDD that is currently being shipped to just one hyperscaler. Other large CSPs are currently qualifying Mozaic 4+-based drives, though we do not know which capacity points we are talking about.
Perhaps, the main reason why Seagate disclosed shipments of its 44TB HDDs now is the fact that its arch-rival Western Digital announced plans to ship its 40TB hard drives in the second half of the year . Unlike Seagate's Exos 44TB HDDs, Western Digital's 40TB drive does not rely on HAMR technology. Instead, it uses energy-assisted magnetic recording (EAMR) and UltraSMR technology that greatly expands capacity at the cost of slow overwrite performance. By making this announcement now, Seagate sends its potential customers a clear message that its HAMR-based hard 44TB drives are more technologically advanced than WD's 40TB offerings.
Seagate updates its lineups with new 32 TB CMR hard drives, starting at $699.99
