Is there a maximum SSD speed?

Good day,

I'm thinking about getting a new M.2 SSD, but I was just wondering if there's a speed cap? I currently have the ADATA sx8200pnp and would now like to upgrade to the Samsung SSD 990 PRO .

I once heard that if you install multiple M.2 SSDs, the read/write speed decreases, is that true?

Specifications:

  • i9-10900k
  • Asus Maximus XIII Hero
  • 128 GB Corsair RAM 3200 MHz
  • Aorus RTX 4090
  • Corsair 1200W power supply

Puh, a 500€ motherboard….

The first PCIe slot and the second PCIe slot and the SSDs M2_1 and M2_2 share a bandwidth of 20x Lanes in the data sheet of your motherboard.

If you want to pack two SSDs into the first slots, the bandwidth of your GPU would be halved – not so horny.

It would be best if you split up your SSDs. (as long as you don’t have anything at the SATA ports).

And instead of changing the SSDs prefer new installations and if all slots are occupied, buy SATA SSDs

Not good at all! As you can see in the first picture, the GPU gets only 8x Lanes instead of the 16x Lanes!

I’d put the SSD down on your own right now!

You can use Slot 1, Slot 3 and Slot 4 as I have shown in the picture without restriction.

Of course, this is true because the data transport via the motherboard is limited.

Which m 2 SSD is the fastest?

Samsung 990 PRO 2 TB

At Tomshardware, the 990 Pro depends on all competitors in all tests. This makes the 990 Pro one of the fastest M. 2-SSDs on the market, even if it is somewhat more expensive than some comparable competitors like the WD Black SN850X.

At the moment I have
ADATA sx8200pn I would like to say that
Samsung SSD 990 PRO change

You can just burn your money, then at least have warm hands

Are limited by CPU and motherboard to theoretical 4GB/s for the M.2 slot, real with overhead approx 3.4GB/s

Some older boards have two m.2 slots, but are designed only for one SSD. There it is in the docue that the pcie abbremmst when the second slot is used.

You don’t have to worry about it with your board.

Oh, I thought you wanted to keep the old one. Because you’re interested in whether the speed is slower at several SSDs.

So the 990 Pro is much faster than your ADATA. Reading twice as fast, writing almost 6x so fast.

If it allows your money, do it. I’m always talking about SSD as soon as a new generation appears. I believe that this is clearly evident.

AH still one of the propaganda of SumSum to the victim file

These benchmark values do not reach for a long time in everyday operation and whether ne NVMe now creates 1GB or 2GB or even more in reading or writing, do not notice as normaluser eh

Right. The largest speed advantage of an SSD is due to the fast access times of the memory chips and you also have in “slower” SATA SSDs.

The sequential R/W values with which the manufacturers are advertised are available at most when copying very (multiple gigabytes) large files and even then you have to weigh down whether it is worth the extra charge only with a copying process going a couple of seconds faster.

It already creates 3.5 / 3GB/sec… Do you have a problem in any application where you say “I need double performance for three seconds”?

hmmm good, that’ll be added and what game

I put a good test on it: after 1.5GB he had reached the height of 302Mb/sek and he kept himself a long time before returning to 170.

I live in London and use the download server in London and I have a maximum of about 140Mb/s … Limited by my Internet line, where my Ryzen 5 is already well-loaded. (Ca 80-90% utilisation on all 12 threads)

In addition, Steam does not even shove over 100Mb when the download server is in a bad day setting

As long as you don’t blow up your internet on 10Gbit/s, no NVMe SSD will be a bottleneck. And even if, for example, on Steam, you will be limited by your CPU because the download must be decromised in parallel.

Downloads faster? Do you have an Internet line that… let’s say that you can spread the 7GB/sek minimum 60Gb creates!? I doubt that you want to invest SO a lot of money in an Internet line
