It’s been a while since I have seen this at $130. The WD SN550 is about $2 dollars cheaper on Amazon. They are both great drives but this is the one with DRAM. It just depends which review you read first as to which one is better or even what colour goes better with you’re motherboard.
DRAM makes this drive worth it for $2 more
The SN550 has SRAM.
That would make the SN550 a better buy no doubt. SRAM is a better technology
I only have Samsung drives so I didn't know too much about Western Digital and Kingston's offerings.
Real world stats on the sn550 is amazing.
1.5GBps when there is cache available (not too amazing, but good).
But the amazing bit?
800MBps write even once the cache is exhausted.
Real-world amazing numbers.
With 1.5x sata's max theoretical speed. It's pretty wild for the entry-level price bracket.
@MasterScythe: SN550 reviews generally indicate the SSD is quite good given its price. However, something is a bit weird with Tomshardware charts and results.
Real world 50GB copy transfer rate:

If you then look at 100GB result, you would notice most NVMe SSDs with good controller and SLC cache get better result than 50GB. So, is this a latency issue or the NVMe SSDs somehow managed to take advantage of SLC cache again later on (seems unlikely) or something else? Or, those are not sustained write tests?
Yes, I saw the 800MB/s bit. That's why I am confused.
