Wow, Surprised at URE rating on Newer (non-Pro) Barracuda and (non-Pro) Iron Wolf drives

Even simple 4K editing with some transitions and text overlays using DNxHR HQX at 4K30 is going to require 222.2 MB/s. (re: 2 x 111.10 = 222.2 MB/s). Same, but at 4K60, would require 444.4 MB/s (re: 2 x 222.2 MB/s).

...which is why anybody doing serious video editing is using SSDs already. Raw, uncompressed 4K60 actually requires ~700MB/s, which is beyond any HDD. Even beyond most smaller arrays too.

HDDs are bulk storage only today. They still do that fine, and will for the foreseeable future.

Remember I'm thinking this for a basic build that has just a C drive for simplifing things:

And assuming a person uses 4 x 4TB drives each at 190 MB/s, a RAID-5 array of such drives would have 570 MB/s (minus overhead) when empty and 400 MB/s (minus overhead) when 70% full and 285 MB/s (minus overhead) when 100% full. Adding another drive or using short stroked drives would shift performance upwards or change the performance per amount storage used ratio respectively.

P.S. Using 6 x 2TB (ST2000DM008) should give 550 MB/s (minus overhead) even with the array full.

For a basic system, get a 250GB BX500. Done. If more storage is required, add a 4-8TB HDD.

For an experienced user that is fine, but some people only want a C drive.

For an AMD user, StoreMI could fix the C drive issue but I think it might take a multi-actuator HDD to work well with 4K30 video editing. (I could be wrong though and maybe the software could do well enough swapping video from single actuator HDD to SSD.)

SIDE NOTE: Would be interesting to compare 4 x 4TB in RAID-5 to 1 x 14TB Multi-actuator HDD. My expectation is the Read performance when both storage volumes are full will be very similar.

P.S. For anyone wondering why I bring up 4K video editing for a build aimed at beginners.....consider even the iPhone SE 32GB (once available as low as $99.99 on more than one prepaid wireless service can shoot decent 4K30 video):

Well, if you want to deal with supporting RAID environments for non-technical inexperienced users I don't see what kind of argument I can make here.

For anyone concerned about using SMR with RAID-5.......All the Iron Wolf use CMR.

However, It is disappointing to see that only the 6TB (and higher capacity) Iron Wolf have the URE 1^15. (4TB and below has URE 1^14).

Perhaps this will change over time as Seagate updates their products?
