Re: Anyone interested in watching me stream?

I've played it - it's a good throwback to the originals. It's exceedingly campy and genuinely funny at times, even if there are frustrating stupid parts. :)

Rubbish. NVIDIA dominates in HPC accelerators.

I was speaking to performance more than market penetration. Nvidia has the mindshare and ecosystem in spades.

Re: New drive suggestions?

For Seagate drive-managed: Certain 3 TB and 5 TB 2.5" drives are SMR (it's harder to tell for 2.5" drives). This obfuscation really annoys me. Archive 5 TB and 8 TB 3.5" drives are SMR (if you shuck one, it's a 99% chance it's SMR). The 5 TB drive is measurably worse in every performa...

Re: New drive suggestions?

That's somewhat surprising. Modern drives store on the order of 2 MB/track; if we assume a 5 platter design (10 surfaces), that's 20 MB per cylinder. With only "tens of MB" per zone, you'd be overlapping only 2-4 cylinders in each SMR zone, leaving a lot of potential capacity on the table...

Re: New drive suggestions?

Does "drive-managed" mean they're zeroing out empty space like TRIM on an SSD? No... SMR drives don't have wear leveling issues, but (like SSDs) some trickery is required to make them look like a "normal" random-access disk device. SMR drives are divided into "zones", ...

I will likely be dealing with HGST host-managed SMR drives in the medium-term, unless SMR as a tech falls out of favor. I highly doubt SMR is going to fall out of favor - I'd bet that it'll be in every drive with the exception of NL-SAS in the next few years as cheap NAND continues to push on the H...

Re: New drive suggestions?

Assuming you stick with lower RPM, I don't think you will get a comparable speed boost this time, as I believe the 8TB models use more platters with only modest increase in linear bit density. Also make sure you get a PMR drive, not SMR. Performance of SMR drives for non-sequential writes is abysma...

More like I wasn't clear - I think your reading comprehension is perfectly fine. :)

It'll faithfully reproduce 5 Hz tones at pretty decent SPL. I intended it only to provide "impact" as my mains have 12" ported drivers already. :P

Shrinking is difficult/impossible beyond a certain point because Windows places files halfway into any partition you install it on. Best bet, if you have the time/motivation, is to reinstall W10 as you plan. I believe there are tools to do this beyond the 50% reduction you've noted, but I don't have...
