Question SK hynix Platinum P41 2TB SSD Write speed dropped by half

[Super Spartan]

Only about 4TB written to the SSD so far, when I first got it, the performance was:



Now, the write has dropped by about half:



the only difference which I think was different is I was on Windows 11 21H1 when I benchmarked it the first time and now I am on the latest 22H2. The read speeds are the same. What gives?

PS: I even tried using the Samsung NVMe modded drive but that didn't change the write speeds.
Antivirus is disabled while taking the test

Laptop specs are in my signature

I have been using mine for 6 months and still getting full read and write speeds. I don't use BitLocker, so I suspect BitLocker may have something to do with it.

no, I never ever used BitLocker and never will.

I ran into a similar problem with my work laptop, it's a Dell Precision 5470. The NVMe inside is an SK Hynix PC801, which I think is the OEM version of the P41. Initially, the read/write speeds were amazing, hovering around 6000-7000. But a while back, I noticed the write speed had dropped to about 2000-2500, though the read speed was still above 6500. The funny thing is, I found this out purely by accident. I wanted to run CrystalDiskMark on an external drive but ended up running it on the NVMe by mistake! Honestly, I probably wouldn't have noticed otherwise. There were no error messages or warnings, and everything else about the daily work on the laptop seemed normal.

I started looking around for any information on what could be wrong and found this forum, among other places, but didn't find any answers. And since it’s a work computer, RMA'ing it was off the table —not to mention how silly it would sound asking our IT department to look into it just because the NVMe drive doesn't perform well in benchmark!

But then things took a turn yesterday. I was using BitLocker on an external drive and saw a message saying, “Device encryption is temporarily suspended. Encryption will resume automatically the next time you restart this device.” Trying to fix this issue (of course restart did nothing), I ended up turning off the device encryption altogether. Then it hit me—could encryption be messing with the write speed? So, I ran CrystalDiskMark again and, bingo! the write speed was back to normal, over 6000.

Now, I’m left with a new puzzle: I can’t re-enable device encryption. Still, I wanted to share this in case it helps anyone out thereMY .

MY SSD is PC801 with same write 2500m/s issue, I try to disable the bitlocker after watching your post , but unfortunately problem still, so I think the problem is nothing about bitlocker, for your case should just a coincidence , there should be some logic that FW will prevent SSD to use Catch, im very struggle cus I just bought a P41, and it is still under delivery, I think I better to cancel the order right now.

Yes and get something decent like WD or Crucial or even Corsair. Kingston is also fine as far as I know.

 

[Ridiculous_Death]

I have two P41 2TB and both have this issue. What a piece of crap
, should've got the WD

 

[igor_kavinski]

Looks like some crappy employees who got fired from Samsung joined SK Hynix...

I think mine is absolutely cooked????? what's going on????

At least your reads are good. That's what applications/games do most of the time.

 

[Hail The Brain Slug]

I can't believe they still don't have a fixed firmware for this. SSDs seem like they're becoming abandonware.

 

[Shmee]

If the drive is under warranty, reach out to SK Hynix and they should give you a refund for a return.

 

[fastandfurious6]

random read/writes at Q32 T16 are also 10 times less than normal......

at least is latency/ μs normal?

basically is all that impacting Real World performance in any way? seq writes only happen once in a blue moon anyway

 

[Hail The Brain Slug]

I think there might be something to the bitlocker thing. I disabled bitlocker (and let it decrypt the entire drive) and my performance appears to be back to normal - no format or secure erase involved.

Granted, I didn't have the 2500MB/s speeds. Mine were kind of floating around 3000-5000MB/s instead of the normal 6500+

Possibly two unrelated issues.

 

[lopri]

What a shame. I was about to order a couple of Hynix SSDs. Glad to have found this thread. I guess I will wait.

yep mine got literally cooked!!!!
basically the drive dies quickly after operating for 1-2 minutes and pc needs total reboot to retry
can't pinpoint what exactly makes the drive to die, any pointers? for science


loading OS in drive:
loads OS but in 1-2 minutes 'computer capabilities' increasingly freeze:
1. the program doesnt load / window doesnt scroll / refuses to do things
2. mouse is still moving
3. can click on other things
4. in the next 10-20 seconds increasingly unable to click on other things,
5. mouse stops moving for 5 seconds

6. BSOD: CRITICAL_PROCESS_DIED


loading OS from different drive:

1. reads data normally, until it doesnt
2. example movie file: can skip forward for 3-6 times, until it doesnt work anymore
3. drive "dies" and becomes unrecognized by OS
4. reboot revives the drive until it dies again



basically cloned the entire broken SKhynix drive to a new drive and OS and everything loads normally now

Leave the drive in a spare slot for a day and don't try to access it. Its firmware may be trying to recover from some internal corruption or whatever.

However, if it doesn't work after 24 hours of being left alone powered up, time to RMA the piece of crap if it's still under warranty.

ebay purchase... listed as new but no purchase receipt

any way to get direct RMA without receipt?

do firmwares really do that? some kind of self recovery on their own? basically it started 4 days ago and it was becoming increasingly worse every day, i.e. 1st day 2 bsods, 2nd day 4 bsods, 3rd day bsod in 2 minutes etc

did a lot of troubleshooting but basically cloning the whole drive into a new drive removed the issue completely, the ssd got cooked

I only have one experience of that (a Sandforce controller based Corsair F60 SSD that fixed itself after several hours of just being connected to running PC. Previously, it would hang within 5 minutes).

Hey everyone,

I bought 2 x 2 TB Platinum P41's last summer. I was copying some large files today when I noticed the write speeds were much lower than advertised. The drives benched normally when I first got them. I ran a bench on crystaldisk and found that my hunch was correct. The drive with my OS installed has significantly reduced write speeds. My other drive which I use for file storage and some gaming is still running at full speeds.

I'm glad I found this thread.

I reached out to SK Hynix and they offefed to refund me stating they would not replace it. This is problematic because the price when I bought it is much lower than current market prices and I won't be able to replace it due to being low on funds right now. They also said I would have to pay to ship it to them because it's out of some arbitrary 30 day window.

I replied expressing my concerns and linking them to this forum post. I am trying to get it escalated so I can talk to someone who actually matters to see if this is something that can be fixed with a firmware update.

I also wrote an email to Gamers Nexus and a few other publications to see if maybe someone with a little more sway could get to the bottom of this and with any luck shed some light on it.

Godbless 🙏 the drive is cooked by design / factory, there's some serious flaw

firmware update would probably be hard to trigger, and maybe it's not even fixable who knows

if there is a referral more people can use the same escalation to get a refund, let us know!

SK Hynix asked me to send them pictures of the drive, told me they would then promptly send me the shipping address. It's been almost 72 hours since I sent the pictures, I have sent a follow-up email as well, and sadly it's radio silence from their end. It would seem they are ghosting me.

Over the holidays?

pictures of drive sounds like nonsense delay tactic, why the hell they need pictures of a chip

they probably dont know what to do and are scrambling

Their customer service reps are probably ignored by their managers and the managers themselves are ignored as being pretty low on the list of people that really matter to the organization. Because most executives with the power to do anything just tell their subordinates to "handle" problems without bothering to do anything further unless a real ruckus gets raised by the customer, particularly on social media.

 

[fastandfurious6]

exactly this is a problem literally everywhere, it's by design

when will these shitty dark patterns be properly exposed so they disappear...

When we start punishing boisterous psychopaths instead of promoting them to high positions of responsibility. It starts with school, the bullies. We tolerate them there instead of getting them expelled.
