KB4566782 Cumulative Update Windows 10 v2004 build 19041.450 - Aug. 11 Win Update

Pejole2165 · 12 Aug 2020

Although modern SSDs have much better firmware and hardware optimisations to improve wear levelling and garbage collection (all of which happens outside of the OS) it is still necessary to TRIM (optimise) SSDs to improve performance over time, this is especially important on SSDs where a lot of delete/ writes occur. I use Intel and SanDisk SSDs and both manufacturers advise running TRIM once a week. according to Intel TRIM does not affect the SSDs endurance, so even if the Windows built in optimise tool is running more often than needed it is not going to reduce the lifetime of the SSD. Having said that I have disabled Windows optimisation and run TRIM manually either from the manufacturers utility or through PowerShell depending on how many deletes/ writes have been done. My OS drive is trimmed once a week, others maybe once a month or less according to usage.

Hi there

@Pejole2165

What data metrics are there these days to show SSD degradation over time -- certainly not for small capacity ones.

Might become more interesting when people start using larger SSD's (> 1 or 2TB) either individually or in RAID arrays / storage arrays.

currently I doubt if anybody using a laptop would notice any difference in performance at all - especially if using typical laptops. - I'm still using SSD's around 5 to 6 years old -- can't say there's anything wrong with performance -- a few microsecs on read / write is hardly going to be noticeable -- we aren't running mission critical "real time systems" on our computers --at least most of aren't I'm sure.

Commercial / Cloud servers - different Ballgame -- often DB's serving 100,000's of queries per sec -- and these use very specialized HDD's like SAS fibre channels etc .

IMO if you've got performance problems on a Windows laptop the problem is almost likely to be anywhere apart from with the SSD.

If it doesn't hurt by all means do it -- but all I'm asking is for ANY evidence that this process actually achieves even the tiniest "NOTICEABLE" gain for an average user,

Cheers

In any case, a quantum leap over mechanical HDDs, specially in case of slow HDDs.

Installing now

Downloaded and installed pretty fast this time around.

Went fairly fast. Performed SFC no issues, at this point only time will tell.

" with 'nary a need for TRIM."........HOW(?) do you know trim is not needed ??

Modern file systems now support TRIM. NTFS does. Every time you delete blocks in a file the OS/file system sends a TRIM command to the SSD with a list of the deleted blocks. The defrag optimize is a big hammer that was originally developed for file systems that do not support TRIM. It sends a list of ALL unused blocks to the SSD. Sending this to an SSD with a TRIM supported file system generally does nothing since the file system keeps the SSD trimmed. There may be unusual circumstances where the a file system TRIM got lost (like a power fail while deleting a file I suppose) that the bulk defrag/optimize might correct. But generally it is not needed. Nor is over-provisioning, unless you are keeping your SSD nearly full all of the time.

So, the whole MS- " Drive Optimization" is not needed anymore.........?!

I expect there are some situations where the file system can get out of sync and not know some logical blocks were deleted. They would eventually be discovered by the SSD when a new write to the logical block occurs. It doesn't hurt to sync the SSD up this way every so often. It isn't urgent ore necessary though.

You'd want to do it after restoring a disk image from backup for instance. Macrium has a default option to do this for you.

I would consider the company who made the SSD drive you are using. You may find they have an optimization for your brand and advice. As for Micro Soft, I would not depend upon them to fix this problem, sooner or later.

" As for Micro Soft, I would not depend upon them to fix this problem, sooner or later. "...........nope, it has no priority at all for MS !
