Scratchdisk

[The117thCon]

Ok so I am curious what you guys think should I go for either 2 1TB Sabrent Rocket PCIe gen 4 SSDs in RAID 1 or a single 1TB Samsung 970 Pro, im using it as a scratchdisk and realised where I am the cost isn't hugely different so my question it one more relieable drive or two faster ones in RAID 1 I will use it for a lot of video production work that I cant really afford to lose mid project.

I am running on X570 so can actually take advantage of the faster PCIe speeds so what do you think I should do?

I'd personally go for the single 970 PRO.

The extra speed of the PCI-E 4.0 drives really doesn't make that much of a difference in real-world tasks, so I'd instead go for some cheaper drives, like the regular Sabrent Rocket, if you go for the RAID 1 option.

I mean its only £30 more per drive for me to go with gen 4, that much i can spare vs an extra £300 to get dual 970 Pros as the point of this is high speed but ultimately very reliable storage as both a scratchdisk, cache and to temporarily house active projects

But why 2 1TB rockets instead of one 2TB one?

[The117thCon]

Reliability, two drives are less likely to fail than one, they would be running in RAID 1 after all

[Kilrah]

Oops, didn't see and assumed you wanted to RAID0 them. 

 

What's your mobo? Normally you'll have one SSD connected straight to the CPU and the other through the chipset, so running 2 in RAID would slightly reduce performance.

 

Not sure of options for dual NVMe RAID with AMD.

X570 Taichi and it does support RAID like I want and sure slightly but on gen 4 as well as most of the stuff ill be doing it wont make a huge noticeable difference as they will bei in slots 2 and 3 if i went with the RAID option

[Kilrah]

I'd go with the dual PCIe4 RAID1 setup then.

Scratchdisk usually means a lot of writes for which the Gen4 drives are not ideal due to their large SLC caches. You'd instead want good steady state performance. WD SN750, 970 EVO Plus would be the best two TLC-based options.
