ADVICE: Upgrade Mac Pro 2013 SSD - SSUAX vs SSUBX?

[juan99999]

I'm looking to upgrade my Mac Pro 2013 256 GB SSD to a 512GB or 1TB model. I was wondering if anyone has done this and what advice they would have. I'm trying to do it the most cost effective way.

I've found some of the older threads, but they are quite dated and was wondering if there was recent insight/additional experience.

Based on my research I'm tempted to get and OEM SSD as I've read that they are the fastest which leaves me to ebay (I'm assuming Apple won't sell me one).

Any real world experience with the speed difference between a SSUAX vs SSUBX? Seems to be a $200 price difference and I'm wondering if it's justified.

Thanks for all your thoughts!

subscribed. I would like to do the same but have no experience on it.

get the SSUBX. SSUAX is slower, some (256GB? 512GB? don't know for sure anymore) of the SSUAX models use only 2 PCIe lanes. one of my SSUAXs has died, none of my SSUBXs had any problems so far.

SSUBX if you can find one at a good price. I was looking for ages along with a SM951 but they were all so overpriced I ended up with a 480Gb Kingston HyperX Predator AHCI PCIe instead.

Edit: Apologies, this was for a Mac Pro 5,1 not a 2013.

You install a HyperX Predator in a 2013 Mac Pro?

SSUBX 2015 or newer

I'm not sure about prices, looks like $500 for 512GB in US, ridiculously expensive

I've had a few over the years, never been able to tell the difference in real world use. It's pretty close unless your disk IO is the bottleneck.

SSPOLARIS does not work in Mac Pro 2013. maybe it will, starting with macOS High Sierra. but so far, they don't work AFAIK.

over in the MacBook forums there's a thread somewhere: IIRC a french guy tried SSPOLARIS in MacPro6,1 and it didn't work. I wanted to buy an SSPOLARIS for my MacPro6,1 because the ad on eBay said it works...

EDIT
found the thread -> #44

What would you consider a good price for a 512GB?

$300? They've been hovering between $350-$400 on the Bay though.
