Intel660p Series M.2 2280 512GB PCIe 3.0 x4, NVMe 3D2 QLC Internal Solid State Drive (SSD) SSDPEKNW512G8X1

I must say that I'm extremely happy with the price the performance and how easy it was to install it ! I have used two different adapters Sintech NGFF M.2 nVME SSD Adapter Card for Upgrade 2013-2015 Year Macs(Not Fit Early 2013 MacBook Pro) and Cablecc 12+16pin 2014 2015 to M.2 NGFF M-Key SSD Convert Card for A1493 A1502 A1465 A1466 both adapters work perfectly installation is a little bit different especially the way you fix it into the motherboard but no problem with it either I decided to keep the first adapter that I mention it here now. I am a heavy duty user or 3D applications like blender 3.0.1 which makes the machine get hot and so do not Forget to put a heat sink on top of the SSD (QIVYNSRY M.2 Heatsink NVME 2280 SSD Heat Sink Support Single Double Sided M2 SSD Cooling with Thermal Silicone Pads Cooler for Computer PC PS5 PCIE NVME or NGFF SATA M.2 SSD Installation, Black) I also bought extra memory all the way up to 64 GB (OWC 64.0GB (4 x 16GB) PC3-14900 1866MHz DDR3 ECC-R SDRAM Memory Upgrade Kit, ECC Registered, (OWC1866D3R9M64), Compatible with Mac Pro 2013) I also have replaced the main CPU with a 12 core (Intel Xeon E5-2697 v2 Twelve-Core Processor 2.7GHz 8.0GT/s 30MB LGA 2011 CPU BX80635E52697V2 (Renewed)) here are the screwdrivers that use to assemble and disassemble my Mac Pro Torx Screwdriver Set,TEKPREM 8 in 1 Security Torx Screwdrivers with T3 T4 T5 T6 T7 T8 T9 T10 Torx Bit,Complete Torx Repair Kit for Mac Mini,iMac,Xbox Controller,PS3,PS4,Computer and Pocket Knife also do not forget Corsair XTM50 High Performance Thermal Compound Paste | Ultra-Low Thermal Impedance CPU/GPU | 5 Grams | w/applicator to Bond the SSD with it and afterBond the SSD with with the adapter all these items where very cheap at the time that I purchase everything but now the price is a little higher. But either way this update totally makes sense compared to what you would had spend at the time of buying the computer with this configuration at Apple when the computer was available, it's totally worth it!. All the components put together makes a very powerful computer. I recommend doing the upgrade it work flawlessly ! I add the descriptions of the components that I also got at Amazon I am very happy Cheers !

NVMe SSD drives are finally coming down near SATA SSD prices and this unit is a beast for the cost and performance. While not as fast as offerings from Samsung, the 660p drive's QLC NAND flash makes up much of the difference by having an additional 240GB SLC cache in front. This cache is a revolving buffer that writes in background to the QLC. Once filled however, you may find files in the 10s or 100s of GBs may slow down at some point but, that's a lot of fast NAND to fill up for the average user. Power users pushing very large video or audio files for editing however may not be as satisfied as they can conceivably run past that cache size and begin writing directly to the QLC NAND. At that point, writes become slower than even the worst SATA SSD's on the market due to QLC's very poor write performance.Drive lifetime is another consideration. From longest to shortest TBW: SLC > MLC > TLC > QLC. QLC's total TBW (Terabytes Written) is about a quarter of MLC I believe, meaning you are sacrificing longevity for cost however even at 400TBW, this will last an average user 3-5 years and those who don't game much or edit media will see longer times. This number however is for the QLC memory only while the SLC will have a longer lifespan. Some percentage of users don't even fill up the 240GB of SLC giving them exceptional value with a drive of this design.In summary, for most users who want fast load times for video games or even just getting into Windows or Linux in seconds, this drive is fast enough that you won't notice the difference between this and a higher performance NVMe SSD. Power users needing the higher initial and sustained throughput of something like Samsung's EVO PRO line may not be as happy with the performance of these QLC drives and should probably stick with TLC/SLC drives.EDIT:Update 1 year later -With the drive a little over half full, I've used only 13.7 TBW out of 400. I do a ton of gaming on this machine and expected a much higher number.Also, I did finally fun into an issue with the front side SLC cache filling up during a large copy from my RAID but using Intel's SSD Toolbox I was able to clear the cache with a single click and bring performance right back up to full speed maxing out my RAID's read speed at about 420 MB/s.Pros:Price/MBFront-end SLC cache makes it a good performerCons:Shorter lifespan than other NAND technologies (low TBW)Once exceeding SLC cache, drive can be VERY slow - NOTE: use the Intel SSD Toolbox to clear this periodically and you'll be fine.

I bought the 2TB model. The installation was simple; just make sure your board has the right M-Key M2 slot. I just turned off the computer, put this drive in, booted up, and went to the computer management portion in Windows to partition and format it. It was a very easy and fast process.It should be noted this drive uses QLC memory, which is the worst and cheapest. If you are doing a database workload or will utilize heavy writes, like writing 200GB+ files regularly, you won't be happy. If you plan to use this as a drive to store applications such as games, you'll be quite happy.This drive has a decently sized SLC cache, so as long as the file writes don't get large and frequent, it'll make the drive overall fast enough; by that I mean 2GB/s or very close to it. If the writes are large and frequent, this drive will be slow. If that is your workload...pay for it with an appropriate drive.My use case is a drive to store all of my games. With many being over 50GB now, you need a big drive if you have lots of games like I do. For this purpose, the drive is outstanding in terms of value. It delivers great performance in the use case of reading all those textures and feeding the RAM and CPU.If you want to use this as a boot drive, you can. It will work well in this case, but there are better options if you want outstanding performance. Still, this is a big upgrade if you're using a magnetic disk or old SSD.As to the durability of QLC, if your use case is application storage, this really shouldn't be anything to worry about. Unless you're doing very high write workloads, the SSD will last a long time. I have a 10 year old Intel SSD, and the Intel tool says it is only 10% through it's life, and I used that as an OS drive for many many years.
