Yeah, unfortunately my laptop's secondary drive has no clearance with respect to the shroud that runs over it. It has space at most to only apply a thermal pad which of course will only make things worse. My primary drive has a thermal pad and heatsink and if I were to swap the two, I am pretty sure the temperatures would be much better.

Maybe you could someday swap both drives, and make this one primary, as it has slightly better speeds too!
But anyways, it's all good this way as well, cuz atmost you would place some games / softwares on this drive, and running a game / app wont put it to 100% load, hence temps won't go so high while in practical usage scenarios.

Practically don't see much difference between the two in terms of usage. For gaming, both will operate close to what DirectStorage is capable of. However, having a DRAM drive as the boot drive is still a better option.

HMB is as good as dram on board the drive. Only issue is that it is affected by windows as seen in a recent windows 11 24H2 update which disabled/caused issues with HMB feature of SN770 drives resulting in BSOD but WD promptly released a firmware fix.

It is not exactly as good but good enough. Had read about it previously on one of the sites, so sharing here for reference as well.

DRAM & HMB

SSDs often, but not always, come with DRAM for caching. While it’s possible to embed the DRAM into the controller, more commonly this memory lives in one or more packages external to the controller. These can be standard DDR3 or DDR4, or be a low-power form of DRAM to reduce power consumption...

It does depend on the controller too. WD SN770 is able to match/beat (even if by a few seconds/fraction of second) 980 pro in some common real life usage tests precisely because of this.

WD Black SN770 1 TB Review - So Impressive

The competitively priced Western Digital WD Black SN770 achieves impressive performance results that match the more expensive Samsung 980 Pro, WD Black SN850, and Kingston KC3000. It seems WD has found a solution to overcome the limitations of DRAM-less designs—very impressive.

Received the drive in 4 days through Delhivery. It was uninitialized with 0 writes as stated. It was on firmware version 731030WD which I promptly updated.

It benchmarks better than my primary 2 TB Samsung 990 Pro drive.

I had transferred about 400 GB from the 990 Pro to the SN770. It is close to 40 degrees when idle and 70 under load, which is okay considering both drives are in a laptop. I had also taken a screenshot of the write performance but deleted it unintentionally. It was about 2500 MBps peak and the cache seemed to give way at around 300 GB, after which the speed was around 410 MBps, which is as expected considering it uses high quality Kioxia BiCS NAND.

Just out of curiosity, how is your 990 Pro benching so low?

Here's mine:

or is it that the samsung is running on Gen3 and wd on Gen4 ??
Click to expand...
It says that the Samsung is his primary drive, so I'm assuming that the Samsung is also on Gen 4?

If the Samsung is indeed running on Gen 3, then I doubt he would have done an apples-to-apples comparison, because it'll obviously be slower then.

On the laptop, the PCIe 4x4 bandwidth is certainly getting shared. However, the benchmark was still too low. I couldn't put a finger on it but later in the day, with the extra space, I decided to finally enable over provisioning on the 990 Pro which is when I realised that I had Bitlocker enabled, which is now the case by default for Windows 11 installations.

After disabling Bitlocker, it seems that it has about a 40% overhead, at least on peak performance.

The CrystalDiskMark benchmark is more representative, so the 990 Pro is about 50% faster sequentially and about the same for random data.

This is true only for Home edition as far as I know. I however enable bitlocker on any drive in warranty as it means no tension of any data leak/recovery when giving the drive/device for rma under warranty.

My laptop's factory image is for Home edition, so that caused it to be enabled by default when I reset everything a few months ago. It is a fully unattended installation and hence there is no specific prompt for BitLocker, unless you are trying to boot another OS from the same drive or trying to repartition it.

In my case, I don't mind system and game files being unencrypted. Mostly concerned about photos, videos, documents which are all synced on OneDrive. I am using the drives unencrypted now, but have OneDrive installed on a Veracrypt container.

Do you have good deal for sn770 2tb
Click to expand...
for 2tb, XPG NVMEs keep coming in stock, WD Blue ones, and mostly EVM ones.
If you are currently looking for an instant deal on 2tb nvme, dm me with your budget, will get you from the Open Box collection (where price is usually 80-90% of amazon mrp.)
And yes, open box units come with bill on your name, and full warranty by brand (unlike OEM)

I must buy SSD from wd black, crucial, kingstone, and samsung only, other brands i dont like because they fail soon without warning and data loss happens.. especially adata

I agree
But WD slammed me once on my face.

I had 1 x nvme for windows and apps, and 1tb hdd for data (continuing since 5yrs).
The HDD had all my personal files, business stuff, content assets, everything, literally everything, which if lost, i'd lose everything that i am currently doing.
Hence I decided to upgrade to a SSD.
I bought a WD BLUE 1tb SATA SSD, and replaced the HDD
And guess what, the next month, the ssd failed.

Tried every form of data recovery, but the drive showed no files on it.
Problem was that it suddenly got terribly slow, and then crashed the PC. Now the pc wont turn on at all, super slow, spinning at the windows logo. I tried to connect it via external enclosure, and as soon as connected, the PC would get anciently slow.
Later, by luck, after approval of RMA, i gave it a shot by connecting it to my phone via the enclosure + OTG connector, and guess what, it showed up! All files intact, except for a few folders. I managed to copy out all my 500gb of data, by batches of 32gb (i copied stuff from ssd to sd card, moved sd card to pc, stored the data, again put sd card on phone and started the next batch.)

Though I got it RMAed and got a new one, but it randomly failed. Which still leaves me with trust issues.

Lesson that I learnt : If it is important enough to be stored for ages, then it is def important enough to be backed up.

Such situation demands backup of an offline backup of a backup saved in onedrive/google drive/icloud (aka original drive+backup drive 1+offline backup drive 2+cloud backup) irrespective of the brand/price of ssd/hdd being used.
