Technically you can slot a PCIe x4 card in a x1 slot, as long as you have the correct adapter for that (or the slot itself is open ended) - PCIe is quite good when it comes to form factor flexibility

That being said, it's not worth doing that due to severe bandwidth constraints, i.e. the drive will perform slower than a regular SATA one due to the slots can only provide a maximum theoretical speed of 500MB/s

yea…i know…but didn't see any m.2 pcie adapter card with that kind of pin

some more pointless for him to do so.

Bro seems ur result is low.. im using the same NVME but 1GB.. usually the higher capacity has better performance

I tested twice, results similar.

From what I remember, capacity in between 500 GB to 1 TB is the fastest one.

Below 500 GB and above 1 TB the performance will be lower and not the top.

Anyway that 2 TB is for storing games only not Windows OS, that slightly different is ok to me and I won’t go change it.

Probably try switch the position between slot 1 & slot 2..

I suspect either bandwidth sharing or some config in BIOS...

By right X570 should have enough dedicated bandwidth for both M22 slots..

The benchmark I did was not even on idle.. was on Teams Meeting ..

Im using X570 board too.. just that only using single slot now..

from spec sheet.. read & write sequential for both 1TB & 2TB is the same

Hi, I am not going to switch, slot one is design for OS, even ADATA M.2 SSD in slot one faster also no point as I still using my Samsung M.2 SSD as OS.

This additional ADATA M.2 SSD 2TB is for installing games or movie REMUX or editing only. That slightly lower won’t impact the real life usage.

I think slot 2 is slower as slot 2 not even provide cooler cap like slot 1, the manual do mentioned not provide for slot 2.

Actually after using aorus gen4 ssd 1tb for a while, the faster speed I don't really feel it in real life. Since my hdd is still sata 7200rpm, so file transfer speed isn't there too.

I paid premium for gen4 ssd, for new buyers I would advise you to only buy for the better endurance rather than speed. If gen3 endurance just as good, save the money and buy gen3 ssd. Endurance here means the TBW.

Orico is doing a promo for M.2 to USB enclosure

RM33 for SATA 5Gb/s
RM37 for NVMe 10Gb/s

Just bought mine

Thanks for the advice. Lucky came asking first before buying it.

Guess my only option is to change the mobo.

Any reasons why you still insist of going NVME? For real world use there's not much difference between SATA and PCIe anyway

ADATA recently switch to a slower controller for the SX8200 Pro
Yours is an older unit which is using a faster controller

Andrewtst unit is newer which definitely uses the slower controller

https://www.tomshardware.com/news/adata-xpg...ntroller-change

Thanks for the clarification, now everything is understandable.

no wonder..

well seem this no longer the best / easily available NVME.. will scout around for future purchase.. looking for a 2TB when price/gb become more reasonable

Yeap
Not only they switch to the slower controller, but they also switched to slower NAND chips as well

The only SSD that comes close to the performance of the previous SX8200 Pro is the HP EX950
Although they are a bit pricier than SX8200 Pro

https://shopee.com.my/HP-EX950-M.2-NVME-SOL...6108.5945137879

No, these are not OEM SSDs, they are actual retail SSD from HP with full 5-year retail manufacturing warranty

Good choice for future then. It still far cheaper than Samsung.

Was thinking that since both SATA and m.2 SSD are about the same price, but m.2 being 5-8 times (correct me if Im wrong ) faster than SATA, it would be more future proof should I decide to upgrade my mobo.

On the other note, would a SATA - m.2 adapter like these work too? I found that my mobo provides USB 3.1 Gen 1, which theoretically supports up to 5Gps, and seeing that most middle range nvme are 2500mbps ~ 4000 mbps, would I get full speed with this adapter?

Wrong terminology
M.2 is available for both SATA & NVMe

M.2 is only the connector. New Wi-Fi cards also use M.2 connector
Not all M.2 supports NVMe and the same thing for SATA, not all M.2 connector supports SATA

You need to check your system compatibility properly

waiting for direct storage before i commit to a new purchase. 1 tb is just not enough

no worry, in theory, it can be solved by a simply firmware upgrade.
but not very sure would affect TBW or not..
so sad to see so many 'high end' nvme ssd counter the same old issue that was happen many years ago.

M.2 is just the physical form factor, and electrically, it can either NVME (PCIE)/SATA/USB

There's no such thing as futureproofing anyway, especially there are plenty of tests that show no real world performance improvements going from SATA to NVME

Using a SATA to M.2 adapter is also a waste too, and worse still your NVME drive will not work as the underlying interface is incompatible

The product you've linked is a NVMe to USB enclosure, which allows you to turn your spare NVME drive into a regular USB flash drive

Again, Gbps =! GBps (very different units)

USB 3.1 Gen 1 only supports up to 5Gbps (gigabits per second), which is about 625MBps (megabytes per second). Most NVME drives are quoted in megabytes per second (MBps)
For instance, if a NVME drive has read speeds of 2500MBps, then by mathematics, it should be 2500x8=20000Mbps=20Gbps
PCIe gen 3 x4 has a maximum theoretical speeds of 32Gbps (or 4GBps/4000MB/s)



So no, you won't be able to use NVME drives on that board, unless you like slower than SATA speeds due to PCIe link bottleneck

8 bits = 1 bytes, mind you
