Intel660p 1 GB Internal Solid State Drive - PCI Express - M.2 2280-1.76 GB/s Maximum Read Transfer Rate - 1.76 GB/s Maximum Write Transfer Rate - Retail - 256-bit Encryption Standard

I purchased these quite awhile ago. I have not a single complaint about the performance of these drives. I have 4 of them in raid 0 on a asus hyperX16 m.2 adapter and never had a failure in my array even after 2 years and different builds.I would purchase again if I need more 1tb drives.

I get 1610 MB/s write and 1738 MB/s read in MacOS. Not as fast as my Samsung EVO’s but much cheaper and it is perfect for my zippy music server. A nice upgrade. It gets hot during writes, so some form of heatsink is recommended to avoid throttling. In my mini ITX fanless case, I had to mount it under the motherboard just a few millimeters from the case bottom. I used 2 thermal pads to thermal couple the drive to the case and it worked like a charm. It doesn’t get hotter than 41° C while writing! Without the thermal coupling it would reach 70°C pretty quickly and throttle.

The drive fit perfect. I upgraded from a 512 to this and it worked perfectly.

I purchased 3 of the 660p for cache on an Unraid server. They are fast but only for a short period of time. After the initial buffer is consumed, it gets extremely slow. I don't know if this would help someone, but it is what I found with the 660p.

I order this and several other computer parts for a computer my son was building so all I can say he loves it and has said that it was perfect for the build.
