Really slow SSD? did I get scammed?
Posted by ElectronicShoe6220@reddit | buildapc | View on Reddit | 17 comments
I just built a new system, with a B760M-H motherboard that supports NVMe drives, I bought a WD green 250gb SSD, that apparently should have 2000MB/s speeds, but I've been noticing really choppy performance in just windows, and when I ran a benchmark I'm getting like 90MB/s in read and 70 in write

WD green is a QLC, dramless garbage drive.
The basic WD drive you should buy is the sn580/sn5000. And get a 1tb drive.
250 only use a single channel from the controller that makes them the slowest possible drives. And for the love of god don't use a 250gb QLC drive for Windows. it will shit itself at the first download or cumulative update.

I can't really return it, but I can get a replacement, is it really that bad that I can't run windows on it? I have a sata ssd from crucial and it ran smooth, an nvme should be faster right?
John_Mat8882@reddit
If the crucial you have is a MX, even being sata the MX has dram and TLC nand, it's fairly superior to handle windows than the WD green in NVME format.
ElectronicShoe6220@reddit (OP)
Yeah it is MX, I never had problems with it, but this nvme drive is struggling to open file Explorer too, I'm stuck with it though, can I atleast use it for games once I get a replacement?
John_Mat8882@reddit
again check the authenticity with Crystaldiskinfo.
But you can definitely use that for a secondary drive, drop it in the lower motherboard slot and install games there.
Be aware not to set any temporary file such as AMD relive or Nvidia shadow play recording feature on that WD green and force pagefile to run off your C: drive.
Be aware that installing games there or downloading them there may take longer as the write speed of that WD green may tank below older HDD speeds (for sustained writes). Which is probably what you are experiencing now as Windows continuous background I/O is probably exhausting the drive already.

Oh so, my drive isn't really defective? through crystaldiskinfo, it does say all the correct details, nvme pcie 3.0, the model etc etc, and it's un used as well.
is the drive really that bad that, it just dips to 90MB/s speeds?
John_Mat8882@reddit
Yes, these are QLC Nand + dramless wonders. Even Crucial P3(+), Kingston NV1/2 do stuff like that (Kingston nv3 has improved a bit tho).

ah man, what a bummer, I should've done my research, I'll just repurpose it somewhere then.. Thank you for helping me out!!
John_Mat8882@reddit
Unfortunately the numbers are always there to fool the unaware buyer.
You think this is 2000mb/s it's certainly faster than a MX SATA that is capped at 550mb/s..
Mud-Butt1@reddit
QLC drives are not great for large file transfers. They start off full speed the creep down very quickly. QLC is generally cheap and OK for standard operations and should be fine for most uses. Take a large file 4gb file for testing and monitor you file transfer speed. If the drive cache is clear you should see full speed when starting the you'll start seeing it drop down....

In which benchmarks?
Manufacturers advertise their peak sequential read/write numbers, but real world usage is primarily limited by IO latency, aka how fast the drive can read/write to a single randomized block.
ElectronicShoe6220@reddit (OP)
CrystalDiskMark, and yeah it's actually slow or defective even, Windows lags as well.
DZCreeper@reddit
I would definitely return the drive then. Cheapest SSD I recommend for normal use is a 500GB SN5000.

Was it used? Probably defective, just get in contact with WD, they'll probably replace it
op3l@reddit
Just return it if you bought from a reputable place.
Also I'd suggest going at least WD Blue as the green is absolute cheapest of the cheap stuff.

Sorry someone else will know but there are tools to validate the SSD but this feels very slow. Are you using anything else in pcie like built in wifi that’s sharing channels ? I’d check crystal disk info.

No except the GPU, there's nothing else
