Hi guys,

I plan to get a new system and aware that PCIe SSD such as M.2 is easily 4x as faster in reading speed. But the price is 3x as much.

I wonder if it is worth to buy PCIe SSD (2500+MB/s reading) just for the Drive C (OS, application loading time etc)? Will I actually notice any differences if I just buy normal SATA based SSD (around 500+MB/s reading).

I do aware reading speed is about 4x more... But I wonder in real-life got much differences. Processor wise planning on i7.

Do hope the experienced guru here can share their view.

Usage?

It needs to depend on the load...

pcie ssd is speedier than sata ssd in many areas, except for common use, in which case you don't really notice the differences. yeah it depends on your usage.

imo it's better to spend on 4x of ssd capacity than 4x speed for most users. however, if you're an enthusiast, you know what you want

Well, the SSD will solely be used as boot drive + application loading.

What I wanted is... Impressive OS loading time that I can smile, as well as speedy launching application that make me proud.

Hope you know what I mean...

Just that I do not know what is the actual differences... Will be 4 sec vs 5 sec? 13 sec vs 14 sec?

If it is like 10 sec (PCIe SSD) vs 15 sec (SATA SSD) for loading windows + whatever stuff, then yes, it worth la...

So far I think if can more than 30% in actual performance then sure go for PCIe. If 20% only maybe can consider also... But if 10% only... Forget about it.

if im not mistaken, pcie ssd vs sata ssd will be +-10sec difference in booting...m.2 will be between pcie ssd and sata ssd

I think the boot time will be negligible. Win10 on SATA SSD and it takes me about 10 seconds to boot to Windows.. it'll probably be around 7 seconds with M.2

If SATA SSD 10 seconds can become 7 seconds using PCIe SATA, it worth the money already...

What do you guys think? 30% improvement?

er about boot time, i use samsung xp941 and i disable fastboot on w10. to me it's the same as sata ssd. sHawTY can give you better pictures because he has a sammy 950 pro.

I also in the same consideration between SATA & M2 :

SATA-
SAMSUNG 850 EVO 250GB 97K/88K 540/520 RM424
SAMSUNG 850 PRO 256GB 100K/90K 550/520 RM615
M2 PCIE-
SAMSUNG 950 PRO 256GB 270K/85K 2200/900 RM863

Not sure worth the money for the performance?

I am using an SATA SSD now so boot time around 10 seconds or so. Was somewhat an early adopter for SSD, bought 128GB for 700-ish at the time.

Considered using m.2 pcie but most probably wait till prices drop low enough for 256gb.

I've used both SATA + NVME SSD
The difference between both is negligible as not a lot of apps / games can utilize NVME

Windows 10 Cold Boot Time (Fast Boot Enabled)
Single HyperX SAVAGE 240GB : 9 seconds
Dual HyperX SAVAGE 240GB RAID 0 : 15 seconds
Samsung 950 PRO 512GB : 3 seconds (I kid you not)

But it all comes down to your pocket
If you can afford NVME, go for it
If you think an NVME SSD is too expensive, then go for SATA SSD

dem boot time, make me wanna cry, that sata ssd is fast enough for me, my question is, why is dual Savage is much slower than a single Savage ?

wo nice guess that's the difference between ahci and nvme.

the raid is slow because it takes additional time to load driver and initialize raid.

is this a single ssd setup?

Wow... Hahaha.. That's the exact info I need... PCIe SSD here I come...

For 950 Pro, yes

Nice - but what are you going to use your machine for?

Got it. That's what i thought too. Everything must be blazingly fast

PCIe SSD will be the last thing I wanna upgrade. Priorities go to GPU, PSU, monitor...

just to make you smile, why not. ensure to buy pcie nvme-based ssd, and plug it to pcie slot that connected direct to CPU, not thru chipset. that's all.


side note: since OS have hibernate mode for quite some time, it makes boot-time is not so crucial anymore. tangible benefit maybe faster game loading time and for video editing. that's all.

When booting Windows, the motherboard have to load the RAID driver & instructions first
But once you're in Windows, everything will be faster than a single SAVAGE

Speaking from my personal opinion & experience using many types of SSD, boot time doesn't really matter, what matters most the loading time for applications & games once you're inside of Windows

But with NVME SSD's, you can have both
