Got it on sale. Been using EVO 960 and EVO 970 in other builds, and they're fast and fantastic. On a mini PC I have, the OS was on an 2.5" SSD. I slapped an M2 SSD in, and could replicate the OS to it no problem. But, wife's laptop had a 125GB M2 SSD as only drive. Didn't have a 2.5" SSD. Got this 1TB EVO 990 as a nice replacement. Saw vids showing how to use an M2 enclosure to easily replicate a laptops old M2 OS drive to the new replacement. But, that would cost $30, I had a 2.5" SSD + 2.5" enclosure already, and I was being cheap. So, I replicated the OS drive to the 2.5" external, tore apart her laptop, installed the blank 1TB EVO 990, and tried booting from external 2.5" SSD. Laptop DID NOT want to boot. Kept going into Windows Recovery like the Windows install was corrupted. Spent 2 days messing around with options. FINALLY.. just popped $30 to buy an M2 enclosure (like I should have from the start). Ripped her laptop apart again, put the old 125GB M2 SSD in, booted.. got into Windows. Put the 1TB EVO 990 into the M2 enclosure. Plugged in, recognized as external drive. Replicated OS drive to it. Tried booting from it, but laptop acted like it was corrupted again. At this point, I figured the laptop was just prima donna and had issues booting from external drives. So, on a leap of faith I ripped apart her laptop AGAIN and slapped the cloned 1TB EVO 990 in. After putting it all back together AGAIN, it booted just fine into Windows, and now she has TONS of drive space left.
So, if you're getting this as a replacement for a laptop's M2 drive... don't be stupid like me and waste a bunch of time. Just buy an M2 Enclosure and make replication easy on yourself.
I ran some winsat times on my old EVO 960 vs EVO 990, and the 990 is getting ~1000 MB/s on random 16 vs the 960 ~1400 MB/s. So, the 990 seems slower there.
But, on the 64 bit read/write, 990 is getting ~3200 MB/s on BOTH, while the 960 is getting ~3000 on the read and ~1800 on the write.
So, the 990 is blazing along. It's also newer than the 960 I have, which may be seeing wear-n-tear impact performance. So, I may eventually get one of these to replace my 960, too.
like 3200 MB/s on
