SanDisk Ultra M.2 NVMe 3D SSD review


The Ultra 3D is available only in the 2.5-inch, 7mm-thick form factor. The M.2 form factor will allow the drive to be used with any desktop PC on the market with a free SATA port, or in a thicker laptop with an older SATA connection and a 2.5-inch drive bay, as opposed to an M.2 slot.


SanDisk offers the Ultra 3D drive in four capacities: 250GB, 500GB, 1TB, and 2TB. The last is the first 2TB drive offered by SanDisk. It is also a sign of the times: NAND flash has become affordable enough that a company would even consider launching such a capacity in a non-enterprise-grade SSD. 


The Ultra 3D SSD is specified by SanDisk to hit a maximum of 560MB per second on sequential reads, and 530MB per second for sequential writes, which is right-on for a Serial ATA drive. The theoretical ceiling on SATA allows for only 600MB per second;


the cloning was simple and perfect. The way I did it was to use the USB 3.0 SSD cable, plugged it in, initiated the disk as a simple NTFS drive using the “Create and format hard disk partitions” utility , unplugged the new drive, and restarted the computer. Then I re-plugged in the new drive, and instructed True Image to clone my C drive to the new drive. It took about 30 minutes to clone. 

NCache 2.0

Like most other TLC drives on the market, the SanDisk Ultra 3D uses what is known as a “pseudo-SLC” cache, in SanDisk’s parlance called “Ncache 2.0.” This is used to overcome the weakness of TLC flash when it comes to write operations, and it mostly works quite well. The drive writes to its “SLC-like” cache first, then when the drive is idle, it transfers the data to the flash array instead of writing in real-time from it.

XBox & PS4 Pro – SanDisk Ultra M.2 NVMe 3D SSD game review

Xbox One has their own official SSD made by Seagate however 1 TB cost 200 bucks, a total rip-off in my opinion. Installing it was a breeze. Just slide it into an enclosure, plug it in to the Xbox to format it and you’re ready to go! If you have not upgraded to an SSD yet, I highly recommend you do with this SanDisk. Worth the price for faster loading times. Also there are plenty of videos on YouTube that compare load times with different games if you want to research it more.

It has surpassed my expectations in the PS4 Pro, reducing load times on several of my current games that have, with the original spinning disk HDD, been annoyingly slow. Boot up time ‘felt’ faster, though not dramatically, but the game load times were cut in half in one instance and dramatically in others, making a much more pleasant experience. I highly recommend this SSD drive for PS4 Pro upgrades…also, had no issues with installing it/fitment.


The drive was an easy install, it was easy to restore the OS from the internet, and it’s much faster than the original spinning hard drive, which had become REALLY slow (especially when booting) probably because it was failing. This is not my first SSD rodeo, as I upgraded my and my son’s gaming laptops (Windows) to SSD drives, but this was my first experience at upgrading anything in a Mac. It was relatively the same as a PC, but it was a much more significant improvement.

SanDisk Ultra M.2 NVMe 3D SSD Performance review

Most of today’s high-end 2.5-inch SSDs make use of a specific interface, SATA 3.0 (also called “6Gbps SATA”), to achieve maximum speed versus older, but still common, SATA 2 ports, which top out at 300MB per second. We test all our SSDs on a SATA 3.0-equipped test-bed PC to show their full performance abilities. To get the most speed possible from modern drives, you’ll need a system with SATA 3.0 capability, as well.

SATA 3.0-capable drives will work just fine with previous-generation SATA ports, and there’s scant reason to pay extra for drive speed that your system can’t take advantage of. Any basic current SSD will work just as well, in that SATA 3.0-less scenario.

SanDisk Ultra M.2 NVMe 3D SSD customer review

Works, but should include screw for attachment!

his serves as a caching memory for Microsoft’s new version of flight simulator amongst other things. This significantly speeds things up compared to trying to run anything off a hard disk. The only downside to the unit as I recall was there was little to no guidance included as to how to duplicate existing information, format the disk, etc. Fortunately, I have plenty of experience doing that so find some free tools on the web and off we go. The other issue which was more significant is that it does not include the screws to attach it to the motherboard at the M.2 slot. I had to dig quite a bit to find a screw that small to anchor the stick. Since this is pretty much a standard I would think that it would come with the screw necessary to affix it to the board. The cost is negligible but the inconvenience is significant if you do not have or cannot find a screw that fits you motherboard!
