Hello. Let me preface this request with an explanation of my current situation...

Last year I purchased a 2010 mac pro configured with a new out-of-the-box OWC Mercury Accelsior E2 SSD 960GB which has recently failed. After sending the device back to OWC for warranty replacement and having a weeks worth of testing performed, OWC is now refusing to honor the 5 year warranty that the item has by claiming there is a burnt pin somewhere on the unit.

After asking the rep what would have caused a pin to burn, the rep stated that they did not know but that it's beyond what they consider to be "normal wear and tear".

The previous OWC rep I spoke with stated that they discontinued carrying the Accelsior E2 due to problems with performance and the units having a high rate of failure, which is what has now happened to mine. My guess is that they sold a bunch of these E2's and were hemorrhaging money on warranty replacements, so now they've created a loophole to deny claims based on any reason they can find and Voila! problem solved.

Anyway, its not the only time OWC has denied a warranty claim for a product that has failed us. I suppose we should have known better after the first time. Guaranteed there will not be a third.

So we are trying to find what is in 2019 the best dollar value which will work in our machine for editing video, be bootable if needed and not overheat or tax the system too much. Its a Mid 2010 mac pro 5,1. Processor is 2x 3.46 GHz 6-Core Intel Xeon. The previous PCIe SSD was getting read and write speeds of 823MB/s and 783MB/s.

We'll need both a compatible PCIe card and SSD blades and we'd like it to be as fast as possible within a reasonable price range and that will last longer than OWC's garbage product which only lasted 13 months.

If more information is needed, just let me know what and I'll look and see if I can find an answer.

Thanks in advance for any help on this.
 
Have you checked out the Blade SSDs sticky? NVMe blades can achieve 1500MB/s Read/Write speeds in a basic M.2 PCIe adapter, and if you throw more than one in a multi-blade supported M.2 PCIe adapter with bifurcation then you can achieve speeds significantly more than that.
 
Wow, another OWC failure! I guess, other than simple mechanical stuff such as brackets and adapters are prone to failure in case of OWC brand. They get slaughtered here from time to time, but it really becomes questionable. I wonder if they are aware of this. MR is a big forum, they will feel a dent for sure. As the commenter before, check out this exhaustive blog down below.

Blade SSDs - NVMe & AHCI

The short version mixed with my personal experience ist this: If you go with a 4-blade adapter, the Highpoint card 7xxx used to be the very best one to use for a very long time. Lately, the Sonnet Fusion card came out, which is also a great card and Mac Pro 7.1 compatible. However, if you can be happy with a dual blade card/adapter/setup, the I/O Crest card is the one that I can highly recommend. The cooling is best in class and it works great with older AHCI SSD blades as well.

Just a note here, PCIe switched cards share the total bandwidth, bifurcation is what newer Intel chipsets do slitting the lanes.

Bifurcation should not be used when referring to switches and it's a worse/cheaper solution then sharing the lanes.
 
The Sonnet should have official Apple support for some time, which might be meaningful to some. They’re updating the list of supported blades pretty frequently. Confirmed MP7,1 compatibility does future proof it a little bit. If you can work within those restrictions, it might be worth it. Would look at it as a 4TB maximum for this current generation/release of NVMe blades. The single-sided 2TB compatible blades are rarely in stock and fetching a large price premium right now.

Highpoint support doesn’t want to deal with Mac. Mentioning the word gets issues with warranty. Maybe that will change when MP7,1 is available?

Yeah, I saw the sticky and tried deciphering some of it, then gave up, it's like overhearing a conversation between a room full of people all asking different technical questions and I'm not even sure how much of what I'm hearing applies to my situation. This is a work computer and I've already lost a week and a half having OWC string me along trying to weasel out of the warranty because it was from an approved OWC reseller and not directly through them. I jumped through every hoop they had and they still found/made up a way to deny the claim. I have no idea if there's a burnt pin or not and if it was caused by the weeks worth of testing they performed. I know there were no power surges and I keep a fan in front of this machine cycling cool air through the system the entire time its on and monitor the system temperature through an app icon thats installed on the menu bar. My previous system was an imac and it had heat issues so I'm very conscious of keeping up with things like that. This is a Mid 2010 5,1 mac pro, do you know of an online retailer that has a website that will give products designed specifically for that model so there's no way to get a wrong part? OWC has a way to sort for system upgrades on their site so you can't get anything except something made for the model you're looking for.

Thanks, but I have a 5,1 Mid 2010 mac pro. That Sonnet Fusion is a Thunderbolt attached external, no? This machine does not have Thunderbolt and no way to upgrade it unless something has changed in the past 14 months. If there's a 4-blade PCIe card you could link to that would work in this older model mac and some of the older AHCI SSD blades which are compatible or at least the brand to point me in the right direction. That'd be great. Thanks.

This is a 5,1 Mid 2010 mac pro, and the Sonnet which was mentioned earlier seemed to be a Thunderbolt attached drive which this computer does not have access to. Is there another that they make which would work in this model? Thanks.
 

Just a few more quick questions.

I've been reading about the Samsung Evo Plus and Pro SSD blades found here ( https://bhpho.to/34kZ5Q8 ) and from what I've seen the original Samsung 970 Evo NVMe blades, ( https://bit.ly/2C4uvOD ), give more reliable performance and have less system heat issues in the 2010 mac pros.

Can you take a look at these 500GB EVO modules, ( https://bit.ly/2C4uvOD ), and confirm if they are compatible with this Sonnet PCIe card ( https://bhpho.to/36t0whC ) which is the same that you originally sent the link to.

Also, these Crucial 500GB blades ( https://bhpho.to/34rnh3z ) are about twenty dollars cheaper but slower, and if they will work as well the reduction in speed should still be acceptable considering all of these options will be faster than what I was previously using.

Any other advice you may have which you feel might be pertinent would be appreciated.

Thanks in advance.
 
What was your final decision on the replacement? My OWC Mercury Accelsior failed for the 2nd time this morning. I have a MacPro5,1 (mid 2012).
