Best 16TB SSD external storage for Mac? Drobo 8D?

Hello,

Does anyone have suggestions for a 16TB SSD external storage solution for Mac? It looks like Drobo released the 8D which houses 8 SSD drives and has two Thunderbolt 3 ports. This thing is huge for the desk, so I'm wondering if anyone knows if I could install (5) SSD drives in the drobo 5D3 and get the same read/write performance of the 8D?

Would drives like the Samsung EVO 4TB SSD mounted inside 3.5" converters give me the same performance as buying the drobo 8D and installing...

Clean Mojave install, RX 580, USB

Hello,

Right now I got both ATI 5770 and NVIDIA GTX 970 installed in my Mac Pro.

I want to future proof it (be able to install Mojave) and since WEB drivers from NVIDIA aren't available I have decided to get a Sapphire RX 580 instead...

I have been used to using my 5770 for boot-ups/clean installs etc.

I can't use my 5770 for Mojave install since it isn't METAL-compatible.

The RX 580 is OOTB but what are my possibilities when performing a completely clean install?

Will I be able...

So I found something interesting-and fun, but I'm limited in testing due to only a solo Cinema Display, but want to test both engaged simultaneously to see if the RX580 becomes displayable in macOS... Full Metal Acceleration on both a GTX770 and RX580 in both Mojave 10.14.3 and Win10; I am running Bootrom 140.0.0.0.0 in my MP 4,1->5,1 upgrade.

My NVIDIA GPU is a MVC flashed GTX 770 Founders Edition 2GB with bootscreen-and reports correctly as a 770 since I purchased in 2016. Doubtful a MVC...

Is the latest and greatest Macbook Pro better than a 5,1?

Was just wondering. I know the Mac Pro is slated to come out this year, but my work is getting tougher and tougher on my 5,1 and honestly I don't know if I can wait.

I know there's the nMP but it's 2013 tech and I don't want to drop any amount of money on the trash can.

Was recently looking into buying a MBP because of improved performance as well as mobility.

Thoughts?

I was an diehard Amiga enthusiast and I've always missed having drive activity LEDS.

Since last week I've been fooling around ( and getting positive results ) with cooling down the 4,1 cMP's Northbridge chip with a USB fan whose cable I ran THROUGH a spare cMP 2,1 side cover which I cut a 5mm slot for the cable to run behind the 4,1 and up to a spare PCIe USB card's slot.

My Samsung 970 EVO's PCIe adaptor has a 2 pin power connector and I had a spare green mini LED so . . . ....

I/O CREST w/2x970Pro's WAY SLOW??

* I/O Crest SI-PEX40129 controller card
* Slot 2
* Two m.2 970 Pro 512MB
* Format RAID/0 HFS boot drive
* 2010 cMP 5,1/12 core 3.46 GHz,
* Boot ROM 140
* High Sierra 10.13.6(17G5019)

Read/Write speeds are only 380/390MBs and should be in the 2000MBs. Any idea what I did wrong? I also tried a single 970EVO 1TB and ran AJA with same low speed results.

Had this same set up in a High Point 7101A with warp speeds in the 5000/6000MBs range.

Thanks!

No boot screen? No problem. :)

Warning!: It has been discovered that Windows when installed in EFI mode is corrupting the Mac Pro’s firmware by signing it with multiple Secure Boot (X.509) certificates. Therefore Windows should only be installed in Legacy BIOS mode on the Mac Pro (5,1 and older.) Detailed information on this issue can be found within the...

Rebooted, no change.
Moved keyboard (wired) to all rear usb, still nothing.

Nothing works from rear USB ports.

Apple Technician Guide is really helpful :(

Hi there, I'm upgrading an old Mac Pro to be my main edit machine. I've got a PCIe SSD, a standard SSD, and a 7200 HDD.

If I'm separating based on:

  • OS Drive
  • Media Drive
  • Cache
Which drive should be the fastest?

The OS or the media drive?

Now if we're not talking about video editing and we're talking about editing photoshop files with many layers/masks, would that be better suited on the fastest drive, or am I going to see more speed gains from having the photoshop...

Hi everyone i have some issues trying to install windows 10 on my mac pro 4.1-5.1

Everything is fine until i have to install the drivers via bootcamp assistant (already on win10)

i've trying to re install (win10) so many times but it seems to be a never ending race,

MAC PRO 4,1 and 5,1 PCIe AUX Power

The Mac Pro 4,1 & 5,1 have plenty of PCIe AUX power, unless you need more than 300 watts for your GPU(s). Remember you get 75 watts from the PCIe slot. Each PCIe AUX 6 pin connector in the Mac Pro towers delivers 150 watts. Yes all three power pins in both of the PCIe AUX plugs are connected. The PCIe specifications don't required pin number two to have power, but it also does not prohibit it either. In the MAC Pro 4,1 / 5,1 it is connected. To be clear, this delivers the same power as a 8...

4-kyroM.2 with 1TB Samsung EVO (boot drive)
Internal drive bays x4 4TB WD Black HDDs in RAID5

Problem is with the internal RAID5 drive. It will occasionally not mount and just disappear.

Hello,I don't want to bother the sellers and to return my cards, So I would to know if the Titan or Titan X works natively without the web drivers on Sierra or High Sierra like my 780 GTX does.
Because I did a try with the 1080 GTX and it was simply a nightmare, so I want to go to a Titan X.

Thank you for your answers !

Hi everyone,

I recently swapped my original stock Radeon 5870 graphics graphics card for a Quadro K5000 (Mac Edition, NIB) on my cMP 5,1. After swapping the cards, I set up Windows 10 and Boot Camp (using the workarounds) with the ultimate goal of doing some SolidWorks CAD work with the machine. Unfortunately, when installing the Nvidia drivers (either the Windows Update version, the SolidWorks-recommended version, or the latest version), the screen immediately goes black and never...
