My motherboard has 2 M2 nvme slots. Is it better to use both of them, or just use a single slot with a bigger drive?

Only if you're planning on doing raid for your boot disk.

Raid 0 will slow down boot time. Please do the research.
It will enter chipset then only processor.

for RAID, u need use both.. 2 same NVME drive


if not RAID.

use 1 Bigger Drive 1st.

Because SSD go cheaper by time. you can upgrade space later.

150GB for windows Drive is "just ok"

slower 2sec?


it doesnt impact the reason to get RAID

I also want to raid 0 for boot but it will slow down compared to normal boot.

...
boot? slow 2 sec = not ok ??

Few solid reason to RAID.

check these 2 NVME. ( low speed vs Mid Tier Speed ) 's price







it different ALOT for both 500G version

( 2400 vs 3500 Read ) Different RM100.


Here comes the reason for RAID.

u Buy 2x 512 from Crucial RM178, RAID IT, u get Double Perf.
now you got read speed near 4000 1TB nvme but at much cheaper price.


1~2 second delay in BOOT got what problem?

Or u buy PC just to boot?

I think you get 1tb more faster compared to 2 512.
Better do some research

.......

ya 1 tb 2400 read
is faster than

2x 512 raid0 (2400) read.


yah.
fast..


wa.. somemore ask me go research.....

never said it was for speed though?

In summary, the choice between using both M.2 NVMe slots with separate drives or a single slot with a larger drive depends on your specific use case and priorities. If you need the highest performance and data redundancy, using both slots with separate drives may be the better option. If you require more capacity and cost-effectiveness, a single, larger NVMe drive may be the way to go. Consider your current and future storage needs when making this decision.

I personally prefer using one larger drive instead of filling both slots, mainly for simplicity and to avoid potential heat buildup from running two drives. Plus, I’ve found that a big single drive is usually enough for most setups, unless you really need extra speed or want RAID for redundancy. If you don’t have a specific need for both, sticking with one big one can save you some hassle. But if you’re into tweaking your system for maximum performance or backup, using both could make sense. It just depends on your needs.

The choice between using two M.2 NVMe slots or one large disk depends on your needs. If you need more storage space, two disks can be a good option, allowing you to separate systems and data. However, for optimal performance, one large disk may be preferable, as today's larger NVMe disks often handle workloads better. Also, if your motherboard supports RAID, you can configure it to increase speed (RAID 0) or reliability (RAID 1). Cooling is important to consider, as two disks can get hot, requiring good airflow in the enclosure.
