SSD UPGRADE FOR Z97 GAMING 5

I have a SSD 850 EVO SATA M.2 250GB installed in my Z97 GAMING 5 and want to upgrade to 4 or 6 TB.
I also want to remove that replacement later this year to be installed into a NEW MSI MB build for Win 11.
I realize the upgrade WON'T perform at full speed in the Z97 and that's ok.
I need more capacity and want to use it in the new build.
Can you recommend/specify the upgrade please?
Thanks
Howard

Current drive prices are crazy; I can't recommend anything more than 2TB; a 2TB drive now costs what a 4TB drive cost a few months ago. I would recommend a Samsung NVME M.2 drive like the Samsung 9100 Pro NVME PCIe 5.0 M.2. With current RAM and SSD prices, I would not be thinking about building a PC this year.

Yeah, that's an understatement, the M.2 slot runs at PCIe 2.0 x2. So maybe not get a high-end PCIe 5.0 x4 SSD. Any SSD that you can currently get will be bored, but at least you can use it in a nicer system later.

You can think about something like a Samsung 990 EVO Plus, WD Blue SN5000 or SN580, WD_BLACK SN7100, SN850X. Something that is not completely over the top, but will perform very well once you upgrade the system at some point.

But on those older systems, it might not be such an easy swap. You see, Windows tends to only boot from an M.2 PCIe SSD once you have the BIOS settings a certain way, and if you don't, it can mean some work.

On these older boards, the best settings should be something like such:

Under Settings\Advanced\Windows OS Configuration -> Set Win 8/8.1/10 WHQL Support to [Enabled], Win7 to [Disabled]
Under Settings\Advanced\Integrated Peripherals, set SATA mode to [AHCI]
Under Settings\Boot, any Fast Boot options to [Disabled]
Under Settings\Boot\"Boot Mode Select", set [UEFI]
Under Advanced\PCIe Subsystem, set Above 4G to [Enabled]

Personally, I would wait until you have the money for the entire system upgrade. And this is a system I would actually upgrade, it's getting a bit long in the tooth. Then you just do a fresh install of Win11 right onto the new SSD.


With current RAM and SSD prices, I would not be thinking about building a PC this year.

If you need to upgrade, you need to upgrade. And sadly, we cannot say that the prices will become normal again after this year.

I will quote something I read today:

"Analyst Jukan points out trends suggesting that the current memory crisis could potentially become a permanent state of affairs. At least, any hope for a short-term recovery has vanished, and even a medium-term recovery is uncertain – resulting from the ever-increasing demand in the server sector [specifically for AI data centers], compared to the rather sluggish capacity expansion among memory chip manufacturers. Memory chip production is projected to grow by only 5% annually until 2030 – meaning that by then, it might not even be enough to cover the current demand.

To make matters worse, much of this additional capacity will be directed solely towards HBM (High Bandwidth Memory), thus not relieving pressure on the regular DRAM market. Apparently, the memory chip industry's capacity expansion is very conservative, as each of the few remaining manufacturers wants to ride this high-price phase for as long as possible, and avoid jeopardizing it with their own overcapacity. An additional risk is that a potential bursting of the AI bubble could trigger a significant market correction, resulting in a substantial loss of demand all at once. Unfortunately, no serious relief is expected from Chinese memory chip manufacturers, as CXMT, for example, has reported that its capacity expansion is currently hampered by US export restrictions on semiconductor manufacturing equipment."

The prices for RAM etc. may not come down considerably again, unless the AI bubble bursts for some reason. So now might be as good a time as any to upgrade an old system.

The AI bubble will burst. AI demand has not met the planned infrastructure investment. At some point, real money has to be made to pay for these AI data centers. Prices of RAM, etx. will come down because otherwise you are assuming the demand for AI will continue at this unsustainable pace.
 
Let's see. For sure they spent crazy money on it, without earning much back yet, which speaks for a bubble. On the other hand, if this can really replace most desk jobs as they say it could one day, then I don't know, sounds kinda valuable.

If we just look at the current facts, they have basically reserved any memory chip manufacturing capacity for the foreseeable future. They're willing to pay whatever price, so the market doesn't regulate itself via supply and demand, because demand is not going down at higher memory prices.

Unless the AI-bubble-bursting is right around the corner, this tells us that RAM prices are not coming down substantially again, not this year, not next year.

With a 4th gen, sure, he could try to stretch it for another couple years, if he does office work and a bit of Youtube or something. But if there's any kind of workloads where this system is really struggling, I wouldn't wait for the bubble to burst, it could be years from now, if ever.
