Died after 8 months 7/29/2020 4:16:35 PM

Pros: Super fast while it worked

Cons: Have to get a speedy replacement since it was my system drive. We’ll see how the warranty process goes.

Got a blue screen and a day later the drive isn’t detected in BIOS. My other drives show up fine. Tried reseating and resetting BIOS but no dice. It’s dead.

Overall Review: Bought a WD solid state drive as replacement.

High speed drive 6/21/2020 11:19:23 AM

Pros: I bought this to replace a 128G SATA m2 drive. The difference measured dramatically better. I wish I had kept the crystal disk mark info.

Cons: None.

Overall Review: I didn't take time to resolve the issue when Acronis would not seem to allow me to reload my full backup.
Since I went from a SATA to Nvme and UUIDs of all the partitions etc changed, now that I did a full reload of Windows and Linux I'm glad I did. Linux uses UUID's of partitions and that would have been a nightmare to resolved (at least for me). I had my system reloaded in about 2 hours. It was fun to watch things load so fast.

Blazingly fast and a bargain to boot 6/20/2020 12:23:11 PM

Pros: I've dropped these 2TB NVMe's into several different higher end builds, in pairs. I've used the 512GB and 1TB drives in a bunch of i7 engineering workstations, as well. Their performance is up there with the fastest on the market (brand "S") but at this price point they are a value proposition as well.

Cons: It would be great to see even larger sized options, a 4TB would be spiffy.

Overall Review: My go-to SSD for performance AND capacity.

Great SSD 6/19/2020 3:37:11 PM

Pros: Amazing boot drive
boots super quickly
took my pc to the next level

Cons: a little warm but i dont have a heatsink for it, so its expected.

Overall Review: I got this ssd to put my windows on, to hopefully improve my stutter issues, and it did, and blew me away with how much extra performance i got.

Top NVMe TLC drive on market 6/18/2020 6:51:25 AM

Pros: -Fastest TLC NAND drive on the market (even faster than the Adata Sx8200 Pro)
-What more do I need to say?

Cons: -None

Overall Review: Hp has just released new firmware for this drive that, according to reviews, including those by Techpowerup, makes it the fastest nvme drive they've tested, beating out the Adata Sx8200 pro, the Samsung 970 Evo and just barely edges out the Samsung 970 Pro. Where it does this is on having the lowest latency and the fastest, low queue depth random read and writes (this is what really determines how fast the user experience is, not sequential performance). The new firmware should be available on their website now.

I've had the 1TB version since November 2019 and I haven't had a single issue with it as the boot/OS drive on my daily gaming/content creation PC. I've been so impressed with it, that I picked up four of the 2TB capacity, placed them in a Highpoint Storage SSD7103 pcie 3.0x16 m.2 adapter with hardware level RAID 0/1/10, put them in RAID 0 and have the cumulative 8TB acting as the top storage tier in my Server/NAS (I have a 10GBase-T home network and an intel X710-T4 four port 10gig NIC with all links aggregated in my server/NAS giving it a 40Gbit backbone). The HP Ex950s in my server do tons of little writes and huge writes everyday and I haven't had a single endurance issue yet.

Overall, for PCIe 3.0x4 M.2 drives, this is the one I recommend above all others.

Great so far. 6/5/2020 12:58:26 AM

Pros: Fast. The specs on this drive are excellent for the price.

Not quite as fast as the Samsung Evo Plus but it cost half as much.

Cons: Does not show up as a drive in my BIOS.

This is a really minor thing. See review.

Overall Review: My BIOS does not show this as a bootable drive, but it does show up in the NVMe options section, and works and boots just fine.

Real-world performance (using Blackmagic Disk Speed Test) is 2.6GB/s write, 2.8GB/s read. Bytes, not bits.

In comparison, my SATA III SSDs get about 475MB/s write, 516MB/s read.

Protip: if you have an older M.2 slot that only supports Gen 3 x 2 lanes, get a PCIE M.2 board. They are inexpensive because they do not need any electronics, just a M.2 socket and PCIE contacts. That way you can get full performance out of this Gen 3 x 4 SSD.
