pug_s I really don't understand why Sata specs haven't changed since 3.0 while hard drive size increased dramatically. Clearly they could've changed the speed from 6.0gb/sec to 12gb/sec or even higher. Reply

It's not necessary because even a dual actuator 7200rpm HDD is barely capable of saturating spec. Reply

It's not necessary because even a dual actuator 7200rpm HDD is barely capable of saturating spec. and the main reason (besides the fact that SAS SSDs exist) for SAS getting higher speeds is because SAS expanders often run 6 HDDs per SAS lane so they need to be fast in order not to bottleneck. SATA's exquivilent to this is a complete dumpster fire that should never be used; but perhaps if the specification for port multipliers wasn't so thouroughly botched there would be more pressure for a faster revision of SATA to come out. JaiJai1 said: any faster and their life spans decrease. Slower lasts longer The exact opposite is true, but not because of the speed of the disk. The reason slow rotational rate HDDs don't last as long is because they are the worse balanced and binned components that the HDD factories come across put together. All the best balanced and binned components go into the faster or more up market HDDs. Reply
leclod "Moreover, Seagate itself has 32 TB offerings built using HAMR, but these new units all use Conventional Magnetic Recording (CMR)" CMR and HAMR aren't mutually exclusive, those 32TB drives must be HAMR drives. And of course SATA didn't evolve past SATA3 because it's useless. I haven't yet seen or heard of an HDD crossing the 300MB/s barrier. Edit : rather the 600MB/s barrier Reply
icraft SkyHawk AI for $699.99, Exos for $729.99, and the top-end IronWolf Pro for $849.99. Later in the article IronWolf Health Management for predictable health monitoring. It's priced at $729.99, so just $30 more than the SkyHawk. Finally, we have the top-end Exos 32 TB One of them is wrong Reply

The 32TB CMR HAMR are new. Dec 2024 article https://www.tomshardware.com/pc-components/hdds/seagate-launches-32tb-exos-m-hard-drive-based-on-hamr-technology-mozaic-3-drives-are-the-worlds-first-generally-available-hamr-hdds "Coinciding with this, Seagate silently published the product page for its Exos M HDDs, which includes a 32TB model using the shingled magnetic recording (SMR) storage format and a 30TB model using conventional magnetic recording (CMR)." We only increased 6.7% CMR capacity after 1 year? Reply
