The IT industry as a whole still hasn&#x27;t quite internalised that servers now have dramatically worse I&#x2F;O performance than the endpoints they are serving.<p>For example, a project I&#x27;m working on right now is a small data warehouse (~100GB). The cloud VM it is running on provides only 5,000 IOPS with a relatively high latency (&gt;1ms).<p>The laptops that pull data from it all have M.2 drives with 200K IOPS, 0.05ms latency, and gigabytes per second of read bandwidth.<p>It&#x27;s <i>dramatically</i> faster to just zip up the DB, download it, and then manipulate it locally. This includes the download time!<p>The cheapest cloud instance that even begins to outperform local compute is about $30K&#x2F;month, and would be blown out of the water by this new Samsung drive anyway. I don&#x27;t know what it would cost to exceed 15GB&#x2F;s read bandwidth... but I&#x27;m guessing: &quot;Call us&quot;.<p>Back in the Good Old Days, PCs and laptops would have a single 5400 RPM drive with <i>maybe</i> 200 IOPS and servers would have a RAID at a minimum. Typically they&#x27;d have many 10K or 15K RPM drives, often with a memory or flash cache. The client-to-server performance ratio was at least 1-to-10, typically much higher. Now it&#x27;s more like 10-to-1 the other way, and sometimes as bad as 1000-to-1.

It&#x27;s going to be rough without Anandtech reporting anymori wonder if a new outlet will spring up to fill the void.<p><a href="https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=41399872">https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=41399872</a><p>Here&#x27;s to hoping this PM9E1 drive makes it into the Samsung EVO 9x series drives..<p>I&#x27;m curious why the capacity only goes to 4TB, aren&#x27;t there a bunch of 8TB NVMe&#x27;s out there? When will we see consumer-grade 16TB SSDs? Capacity hasn&#x27;t seemed to increase in more than half a decade.

Why don&#x27;t all drive makers (both solid state and rotating) use a RAID-like structure to offer drives with any speed or reliability level that buyers want? Seems like it could be much more efficient to put RAID into the drive than to wrap it around multiple physical drives. Maybe it would actually decrease reliability (you lose all the storage if part of it goes out and you can&#x27;t replace component drives)? It seems like it would be a way to get large permanent storage that is as fast as SRAM, which has been a holy grail in computing for a long time, to get past the CPU I&#x2F;O bandwidth bottleneck presented by slower drives.

&gt;<i>Comparatively, we now see the Gen 5 Samsung PM9E1 achieving a whopping 14.5 GB&#x2F;s read and 13 GB&#x2F;s write</i><p>Isn&#x27;t this comparable to DDR3 memory?<p>I wonder if at some point we will have GPUs extend their memory with like a raid array of SSDs.
