Product ReviewsSamsung SM951 512GB Internal (MZHPV512HDGL) SSD

One of the best upgrades you can do for your old Mac Pro!

Works great in my upgraded 12-core Mac Pro 5,1 combined with a Lycom DT-120 PCIe adaptor. Really excellent read-write speeds and super easy to set up as the main drive after cloning my old SSD with Carbon Copy Cloner. Just make sure to put it in slot 3 or 4 for maximum speeds.Read full review...

Great upgrade for my cheese grater

This worked out great for my late 2009 Mac Pro but it did take some time to have it set up correctly to see its max speed. I had initially put this on the second 16x lane PCI-e slot but was only getting around 250mb/s write and 700mb/s read speeds. I followed the advice on one of the other reviews here and put in on the 3rd 4x lane PCI-e slot and my read speeds doubled to around 1400mb/s, which is what I was expecting. The write speeds were still terrible, at 200mb/s but I was able to sort this out by enabling TRIM on my system. Enabling TRIM got my write speeds up to the expected 1400mb/s. Hope this helps!Read full review...

Amazing Speed SM951 AHCI type

In my MacPro2012 PCIe SM951 gain Write 1500MB/s and Read 1800MB/s Over! I’ve never seen such speed before. and OSX Boot takes Only 20sec.
M.2 M-key AHCI type are going to be rarely. I think they are still keep top speed for bootable OSX not only data storages.
I’m very happy to get it.Read full review...

SM951 AHCI 512

Arrived quickly.
Dropped this on a dt120 and Into my Mac pro 5,1. Recognized right away, formatted and installed OS and was able to boot from it immediately. No SSD on the PCIE bus, but I do have one in one of the SATA slot.
BM shows SM 951 consistently over 700 R/W where SSD was 250. A bit expensive, but it keeps my MP going for some time! Very happy with drive. Read full review...

Fast SSD and easy to setup.

This is a really fast SSD, easy to install and setup (AHCI) for the money, especially if you have an older MB. However if you don't have a M.2 x 4 socket available, you will need a PCIe adapter ($18-$26) to take advantage of full speed. I read that it has higher latency by comparison to NVME, but for the most home users that is not a problem.Read full review...

Great upgrade for silver Mac Pro 3.1

Read and write speeds greater than 500 mbs, very easy to install and it boots perfectly. A better solution than what Apple is selling.

This product was installed in a Mac Pro (mid 2010). It works excellent. Unfortunately, the price is extremely high.

Excellent service

Still a cutting edge product to use in a classic Mac Pro. Used with a m.2 adapter card. Very fast and reliable so far.
