Thanks for a very informative and precise video!
I've got an external ssd as a media server .
Is there a life expectancy figure for reading cycles?
Another maybe stupid question
my ssd sometimes seating in a drawer for weeks.
So it can't preform wear leveling but it also not in use. Is there any effect to a seating data? Besides the material degrading
@eriklamelakillingspree7690 Says:
Can you explain further how HMB would have a negative impact on gaming performance?
@johneygd Says:
I tout that ssd drives became the holy grail solution for reliability,speed and life span over harddisk drives,by since i know that also ssd drives do rely on power in some form or another to maintain it’s data,i have changed my mind about ssd drives,why couldn’t they just invest ssd drives or flash cards wich will work the same way as rom chips in wich the data has to be burned in wich can be only erased with a laser if it is not protected,so why not relying on those rom chips instead for preserving data forever,damnit what a letdown about the vulnerbility of ssd drives🥲🥲
@helladubbz Says:
Great video thank you very much
@RichardBejtlich Says:
Superb video. Is there any way to check how well used a SSD has become?
@The_Pariah Says:
Recently found this channel and he deserves a lot of praise.
I came here wanting to learn about DRAM-less, and he definitely covered it.
Plus, I learned a couple other things I didn't know about SSDs.
The added graphics are really nice.
10/10 channel. Easy upvote from me.

Since some drives will reconfigure MLC to SLC for cache it seems like they could also do this when getting older and errors increase. Any manufacturers do this to extend the life of their drives ? (probably no good business case though ... :-/
@InuYasha-SitBoy Says:
i come for the info, but i stay for the accent
@Vednier Says:
Need corection on HMB. 1) Normally Dram cache used for cell translation tables, not data writes 2) Normal Dram cache is 1mb per 1Gb NAND, so its 1GB of Cache for 1 Tb drive. HMB can provide much smaller size, they say its 128Mb on Windows and up to 256 on Linux. 3) Smaller cache do affect performance, but not linear writing (this mostly handled by SLC cache) but random writes and reads since drive cannot contain whole translation table in DRAM.
@Bob-The-Guy Says:
Does increasing the size of Over Provisioning prolong SSD life?
@hasansalim1868 Says:
Hi Chris. Thanks for the update. Quite refreshing indeed.
@sebastjansslavitis3898 Says:
I wish you could configure your SSD to be SLC, MLC, TLC etc. Like with jumpers or something, would be cool. Or they could make that if cells gets unstable it automatically switches to less bites. I assume memory cells are same, just different controller or protocol or something
@erb34 Says:
We all love a little bit of TLC.
@johndrake3472 Says:
You explain things so well to the layperson - it’s a talent, I appreciate you.
@vinishshetty8055 Says:
Always buy ssd or nvme ssd with DRAM and Cache.
@aldus3833 Says:
You did not mention Write Amplification. Maybe in the next video about SSDs...
@Rivenworld Says:
Astonishing, thank you so much, I never knew there was so much behind SSD's until now, thank you so much - Legend!

Earthlings, after viewing my visual lark scope I see you creatures down there are not cleaning yourselves after you take a dump in the bathrooms. Sitting for hours at your computers and ignoring the signs of taking a shit. Well....read below.
Why do I have to wipe my anus repeatedly after having a bowel movement?
This is an automatically translated article.
Post by Master, Doctor Mai Vien Phuong - Department of Examination & Internal Medicine - Vinmec Central Park International General Hospital
If you have to use half a roll of toilet paper after having a bowel movement, chances are you have an underlying medical condition. Not to mention, wiping a lot can make you itchy and uncomfortable when you finish going to the toilet. Ideally, after a bowel movement should only use two to three times to wipe the toilet paper. If you're experiencing something that's bothering you, see your doctor if your symptoms persist.
1. Why do I have to wipe my anus after going to the bathroom so much?
There are a number of health conditions that can make wiping more difficult or affect your ability to feel completely clean after going to the bathroom.
Remember that every person may have to wipe a little more than usual from time to time. But if you find that excessive wiping is the rule and not the exception, consider that one of these conditions could be the underlying cause.
Anal abscess or fistula An anal abscess is an infection of the anal gland that causes pain, redness, and drainage in the rectal area. The discharge may be blood, pus, or stool. An untreated anal abscess can develop into a fistula. Anal fasciitis are skin masses that develop as a result of friction, irritation, or recurrent inflammation. Common causes include:
Chronic diarrhea Constipation Hemorrhoids Crohn's disease The skin of the anus can stick to the stool and make it difficult to clean the anorectal area after a bowel movement.
Leaky gut Leaky gut is also known as fecal incontinence. It happens when you have trouble having a bowel movement. You may leak stool with gas or find yourself leaking stools throughout the day.
Hemorrhoids Hemorrhoids are swelling of the veins inside or outside the rectum. They can cause symptoms such as itching, pain, and bleeding.
Hemorrhoids are quite common. Research estimates that 1 in 20 adults in the United States and about half of adults age 50 and older have hemorrhoids. Hemorrhoids can be difficult to clear completely because stool can get on them.
Don't forget to wipe your ass!!!!

If HMB DRM-less drives use the computer's RAM, how does that affect the life of the computer's RAM, or is that an entirely different kind of technology that has no life expectancy issues. Informative videos. I find them very useful.
@tutacat Says:
The SLC cells, are actually just using TLC-capable cells for SLC (1-bit).
This probably depends (you could have cheaper hardware for just SLC cache) but the vast, vast majority will use random cells as SLC cache for wear leveling.
@tutacat Says:
Yes, but it stores more bits per cell, so you need to erase it less because you have more capacity.
Also, 3D NAND is a different technology that actually has much more lifespan because of how it works.
@250bythepark Says:
Great video, I think this is one of your best

11:20 I cannot find "trurbo" on the image.
@user-ik5uw9rf9o Says:
Wear leveling (one that needs RAM) is not explained,
@hexinli Says:
This should be held up as the "Gold Standard" by which all technical explainer videos should be judged. Clear, concise, broad yet detailed coverage of the topic, and lots of "why" mixed in. I tip my hat, sir.
@IN5T1NCT66 Says:
Is Mvne or the likes of SSDs good for long term storage ? your vides have been very informative and clear thank you
@NaPH273 Says:
so in short, i still need a DRAM SSD if i want to have a new SSD drive as a fast-mass-storage and scratch-disk for my editing files such as PSDs, cad(dwg), 3d(skp),... next to my existing nvme ssd boot drive, even if the SSD drive is relatively an older model?
@colt5189 Says:
I've read that SSD's can lose data if say you store the SSD in a drawer for many years and then try and access the data compared to a regular spinning disc hard drive that they say is more reliable for long term storage.
@mapesdhs597 Says:
11:00 - The issue of write cache capacity is why, for expanding my main media archive last year, I bought a WD Blck SN850X 2TB NVMe (adding to a long used 1TB SM961), because it has a substantial 600GB SLC buffer, so copying data onto the drive can go at full tilt for a long time befoe slowing down. Sometimes I've needed to copy as much as 200GB in a single session from an external source, something which just isn't viable using mainstream models with small cache buffers, and especially not the cheap QLC products. I've also been using the 970 EVO Plus and Adata SX8200 Pro because they also behave well for this type of task, but the SN850X is in another league.
Data of course expands, and I'm not yet even dealing with 4K maerial, so to this end I've just upgraded again to a 4TB SN850X. The previous 2TB and the old SM961 will be repurposed elsewhere.
For general tasks though, especially where random I/O doesn't much matter, there is a plethora of sensible choices, eg.for storing converted mp4s of dumped DVDs I bought a 2TB WD SN570, a model which also works very well as a system drive (3s boot to desktop using Win10 with an i5 10400).
I'm glad you mentioned backup at the end. I copy all my data to two separate 8TB Toshiba Enterprise HDDs (same data on both), while a third holds the raw data from the dumped DVD collection. Data backup is something rarely mentioned in the PC space for home users. I always thought it a shame that there's still no such thing as a consumer oriented tape backup technology. I expect many people do backups using cheap SSDs in external USB cases, but in the long term, especially if never refreshed via a full read, these devices are liable to fail if just left in a drawer for years on end. At least with mechanical drives there is scope for significan data recovery.
When you mentioned wear levelling, was that meant to include the way in which SSDs include additional flash, beyond the stated capacity, to serve as replacement blocks as the drive ages? I've noticed that QLC models can have a large amount of this spare area.
Something you didn't mention was the consequence of the industry moving toward ever higher density and capacity individual flash ICs, namely the ability to provide higher capacity drives using fewer I/O channels, resulting in lower performance. SSDs of many years ago often obtained their higher tier speeds by utilising many channels, in part because they had to as IC capacities were lower. But capacities have not increased in line with the reduction in channel count, so some modern products, especially SATA, can be significantly slower than older models.
This is why, even today, for a 1TB SATA I would much rather obtain a Samsung 850 Pro or 840 Pro, used or otherwise, the latter inparticular demonstrated excellent behaviour in TechReport's SSD Endurance Experiment, conducted in late 2013, in which the 840 Pro was the final drive to give up the ghost, by which time it had survived a whopping 2.4PB of writes (I would be very.surprised if any modern mainstream NVMe could come anywhere close to that, especially the plethora of junk Chinese brands one sees on Amazon).

For me the main thing is QD1 latency in Advanced Format mode, for the most part other things are fast enough on most.

Thank you, again for sharing you knowledge!
@ZeeKay80 Says:
This is by far the best explanation of SSDs I’ve seen. So thank you for that. As a next step, can someone pls create an online spreadsheet for SSDs with columns like Type of NAND (SLC, TLC, QLC) | SLC Cache | Interface | Max expected speed | Measured Max Speed | DRAM-less |. It’ll make buying process so much easier

Given a motherboard USB C port and external device, how did you get these transfer speeds, did you use a thunderbolt device?

Since you talk about OS, isit possible to make one teaching is about win 10 and 11 sunset-ing?
I still have some questions.
Like which one is more worth it,since usually they have free upgrades from previous gen?win 10 got 2 more years and win 11 will be 1 yr.
Or is it better to wait for next ver?
Will the TPM2.0 requirement be new standard or its just a win11 thing?
@elkudos6262 Says:
Honestly, I like the Samsung nomenclature better. It's more generalized.
@Markos581973 Says:
I miss the days of HDDs, I miss the little noises and light indicator that it was working. I also hate that I can't settle into any given tech because in 6 months its outdated. Like hit the brakes and let us enjoy our tech for a little while before I'm forced to upgrade.

Enjoy the low SSD prices while you can. Samsung is spearheading the SSD price increases before this year is out
