1) Setup:

• Fast PC (Threadripper, 64GB RAM, system on M.2 SSD, Windows 10 64bit,...)
• 2x HGST He10 HDDs (10 TB, 7200rpm, 200+ MB/s sustained read/write speed!, SATA 6Gb/s)
• Testfile: 50 GB folder with a CDNG image sequence from BMPCCK4k (each image is about 8 MB)

2) Pre-Test:

I tested both HDDs individually => sustained sequential read/write speeds close to 250 MB/s (empty disk) for the 50 GB folder

3) The goal:

I want to Raid 0 those two 10 TB drives to get higher sustained transfere speeds especially when the disks approche 50% capacity (I need arround 300 MB/s).

Videofiles (stored on another HDD) will be copied to the Raid for the time I work on them in Davinci Resolve, only to deliver the data to Resolve. Rendering results will be stored on a SSD (so there is no risk of loosing data even when the raid is totally destroyed). I need at least 10 TB of fast storage, as the RAW CDNG image sequences in 4k are quite large - and I don't have the money to do the same with SSDs.

4) The Problem:

When I convert the two drives in Windows 10 to one "striped-volume" I get a nice 20 TB software Raid 0, but when I test the transfere speed by simply copying the 50 GB folder I get 200 MB/s MAXIMUM transfere speed (thats even below a single drive!). The throughput starts at 400+ MB/s for the first 2-3 seconds filling up the disk caches and some system memory and then plummets to arround 100-200 MB/s, where it stays for the rest of the time.

5) I tried:

different stripe-sizes, an (old) hardware raid controller (even worse results, 150 MB/s max), checking for new system drivers (the Windows HDD disk drivers seem to be from 2006 and are only 32 bit!), checking HGST website for information and of course searching the internet for many many hours (either its a different problem or there is never a solution posted to the problem).

I can't try/use the onboard raid controller of the motherboard (because of Windows bullshit and I can't do a fresh system installation at the moment).

Why isn't it working?! (Setting up a Raid 0 is nothing extraordinary...so I thought.)

UPDATE: After some fiddling with Windows and a system reboot, read performance is high as it should be - only write performance is still bad.

Most retail PC configurations sucks.

I am serious. Look only on top of the range, as below you can find such strange things like top CPU, little memory, horrible or even lack of GPU all of this paired with small slow HDD, all in blinking red-blue case. Such monsters come to life due to simple fact - it is also business. Every company is interested to throw maximum of junk and sell it for highest price possible.

Common things that sucks the most in every retail PC

General parts:

• Keyboard. Keyboards on all retail PCs are just horrible, usually it is $5-10 crap with modern design. 98% of them use cheap membrane approach, 2% left use scissors like on good notes. Both you do not want. Check part about input devices to get an idea that is made for real work.
• Mouse. Same shit. Not so bad as with keyboard, but it is usually cheap small wired or wireless mouse. Mouse is one of three main things (other being keyboard and monitor), so do not save on it. Good mouse for you must be good for your palm size, must be made by reputable firm, and must be produced for quote long time to see the issues. Usually none of this is true for cheap mice.
• Case. Exceptions happen here, but they are all in red book. Companies throw plastics rich "games" cases or ultra thin, bad steel cases. You do not need it, it is DOA products. They look cool and works only for people with severe brain damage and heavy drug use. Bad case won't allow you to install top GPU, will be noisy and will eat dust by kilos. It also usually hard to add things and have limits on HDDs you can install (preferably with good cooling).
• Fans. Usually it is two extremes - one fan in more entry models, and up to 8 in the "gamers" editions. All of them are pure junk usually, even one that with work more or less tolerable noise will start to die in a year or two.
• CPU Cooler. Around 90-95% of retail PCs use bad coolers (or stock ones), they are fine if PC is under no or light load, but as soon as you start heavy editing, grading, encoding, it'll be real mess. Some top configurations can use good ones, but it is rare thing and you usually pay big premium for this.

Power stuff:

• Power supply. Most retail PCs come with default supply that came with case they use. Usually it is real shit. Inefficient, with inflated power ratings. Few manufacturers make quote good cheap PSUs, but it usually do not come together with low noise and efficiency. To be short - you'll get underspecced, noisy and inefficient PSU.

Storage

• SSD. While they dropped significantly, that are still too costly for mainstream retail PCs. And you really need at least one SSD as disk for your OS.
• HDD. Most common size in retail PC is 500GB, all else usually go with 1TB. It is just waste of your money. As you need lot of space. For backup and general storage it is good idea to use slightly below the top sizes (now it is 2-3-4TB) as they are economically more interesting. We'll go in details in corresponding part.

Now we go to the PC components itself:

• Motherboard. Many retail companies not only install cheapest MBs that manufacturers have in their line, they can even order special custom versions with reduced price (and some removed ports, PCI or PCI-E slots). Only in top gamers PCs you can usually see more or less good motherboards. Manufacturer can also use MB without slot for second or third video cards (yes, they are useful for grading).
  Remember - with motherboard now also comes sound part and network chip. Cheap MBs like to cut on this.
• Memory. Memory are usually not extra important if you are not doing heavy rendering or encoding all day. But companies try to save here also. You can find cheapest DIMMS, with worst parameters, with no memory heatsinks.
• Graphics card - GPU. It is not so bad now, as middle to top class GPUs can be seen in retail PCs (most are still sold with entry GPUs somehow claiming that it is "for games"). But no one will select for you card with best cooling system and with better clocks. If you are not gaming usually you do not need top GPU, just middle NVidia one (AMD support is growing also) with lot of memory (DaVinci likes GPU memory and more GPUs).
• CPU. Just ignore anything except top of the i5 and i7 lines for mainstream (now it is 1150 socket) and enthusiasts (2011 socket), including all AMD chips (they are cheaper, but you later pay it out in electricity bills :-) ). Usually it is models with K in the end (overclocking ready). Retail companies like to use one year old CPUs, and all the range, starting from Celerons (so consultants can push something with people with any amount of money).

Next part will be about places for getting stuff.

Provide you input, if you agree/ do not agree with something.

i;ve tried it in every way to do it but no luck

I tried this guy apps on a mac and it works perfectly

How can we do this on a pc? anyone knows how to do pixel summing? Thanks

thanks seth

Anyone get the GH3 to connect to your PC for WIFI photo transfer? Anyone get a Mac to work?

I was wondering what is the optimal hack/settings for GH-2 if I have a slower pc? I just finished editing for a DepicT film festival and the Full HD playback was slow when i started to tweak the videos.

My pc specs: (general stuff) Amd phenom II 920 - 2.8 GHz 4 core 4870 radeon 8 GB ram DDR2

What should I do? Should I shoot in 720p from now on? Should I use a diffrent workflow (now I just threw .H264 video in adobe premiere)? Is there a way I could encode videos to a diffrent codec before I edit (I know I will be loosing quality...). Are there any other tricks and tips in post, if so let me know please :)

Processor: 2.53Ghz Intel Core i5

Memory: 8GB

HD: 500GB

Perfect working condition

Extra: Body protected with Black Case Keyboard protected with keyboard Skin

My mac laptop has finally given up and it is time to upgrade. Since i'm doing a lot of music, photography and now video since acquiring a GH2 in january (which is giving me great joy), i'm considering splashing out on a dell XPS 8300 Desktop going all out Max memory, max graphics and a raid hard drive....

Has anyone got any suggestions apart from this beast would be greatly appreciated. Please no mac chat! i have been burnt. I must say their customer service was great but the machine itself was not up to the job and kept breaking down at the most critical of times making me look like an ass loosing me good gigs.

I currently have a decent enough samsung screen but i will be upgrading to a 32inch LED screen in a few months for video work and pleasure.

Thanks
