I'm guessing people are considering these tier D based on the lack of DRAM cache. They are not marketed as high performance like the WD Black series.
Relative to a mechanical hard drive it'll be way faster. Relative to other SSDs it may be faster or slower but the difference will be much smaller.
Blue SATA is probably the same as the variable BOM Sandisk SSD Plus drives. I have multiple of those used as replacements for mechanical drives and they've been fine.
Blue SN550 NVMe has gotten fairly good reviews as one of the fastest DRAMless drives. Example [tomshardware.com]from Tom's hardware. It's uses HMB so it will use up some of you system RAM though.
·
Why do you categorize this as tier D? I've used WD blue for over 6 years now. Zero issues.

Holding out for WD Blacks on sale, but thanks for the heads up!

EDIT: SN750 1TB is $119.99 right now [amazon.com]
Not bad! Though I did buy the same drive in November 2020 for $115.99

I can't speak for WD blue SSDs but having owned a WD red SSD. Any ssd is better than a red. Red is like the mechanical drive of SSDs. So I can't imagine the blue being worse than a red. Freakishly slow loading everything. And yet they both come with 5 year warranties. Take that for what it's worth

I could not find anything about the WD Blue 3D NAND SATA drives having DRAM or not. However, performance actually seems to be decent according to this review [tomshardware.com]. That shows it's close to a Samsung 850 Evo. Hopefully, WD has not messed with the BOM lower performance since that review in 2017.

These are actually also sold as the Sandisk Ultra 3D SSD. I had forgotten that WD has the even lower performance Green line.

In any case, I'm still wondering if / when we'll ever get back to the ~$80 1TB NVMe pricing from around Nov 2019. That was drives like the SX8200 with DRAM too.

the old wd blue --non 3d-- does not have dram. This version, the newer 3d nand one, has dram. It is identical to the Ultra 3d drive and is a good drive. I consider it to be a high performance sata ssd, it is also considered to be a performance drive on NewMaxx's extensive ssd database. It competes with the other performance sata drives such as the 860/870 evo and mx500.

It doesn't have dram, but it does have a cache as a substitute to dram.

The performance doesn't match dram for sustained rights that eat the cache up, but sustained rights go into the hundreds of gigabytes at a time, so it's for very specific cases where you're moving many/large files to the drive.

Quote from StevenA5412 :
Just replaced my WD NvME with a Samsung. The samsung is almost twice as fast read/write.

WD is only good if you're on a budget. Otherwise highly recommend samsung instead
Unless you're in the <5 % of PC users who have a use case where you can tangibly use the increased Read/Write speed, spending more for a Samsung will make no difference.

So for the rest of the PC users, you won't be able to tell a difference between a SATA SSD or a top of the line NVMe PCIe gen4 SSD for general use, work, gaming, etc.

I have several of the 4 TB WD Blue 3d drives. They're excellent drives. Highly reliable and fast. They are also TCL..

I would say the one drawback I hear about these drives is the write endurance being low. But at 600 TBW, I could write 82 GB every day and it would be 20 years before I hit the limit. So I don't see it as an issue for the 4 TB drive.

WD's system RAM caching with their drivers does a very good job so this is perfectly usable even in a high performance system as an OS drive. Far better for responsiveness than the cheapest NVMe drives that you often see in prebuilts.

I'd probably say it's more like a tier B drive in real world performance. Not the very best possible drive you can purchase but nearly as good and excellent for the money.

The NVME are good for secondary drives. I would not use this for a primary drive (no DRAM)

Go here and scroll down, you'll the comparison to their Black series.

https://www.amazon.com/Blue-SN550...B07YFF3JCN

But as others said, their SATA are good for primary.
