Not interested in m. 2,looking for sata drive only.

That ssd will be used only for windows installation. Other large programs will be installed on secondary hdds.

Modern motherboards use SATA III which maxes out at a throughput of 600MB/s (or 300MB/s for SATA II, in which case, it’s time to upgrade). Via that connection, most SSDs will provide Read/Write speeds in the neighborhood of 530/500 MB/s. For comparison, a 7200 RPM SATA drive manages around 100MB/s depending on age, condition, and level of fragmentation. NVMe drives, on the other hand, provide write speeds as high as 3500MB/s for Gen 3 and 5000MB/s for Gen 4. That’s 7x over SATA SSDs and as much as 35x over spinning HDDs!

@shreeux Those 300/400/500/3500MB/s speeds are for sequential speeds of ssd which have no relevance with typical operating system/software performance for which random 4k read write speeds matter the most & those you won't find in even 3 digits(aka 100MB/s or more) for both of them. For reference, probably the best NVMe ssd, samsung 970 pro has random 4k read speed of less than 70MB/s.

i tried installing a large game on a 120gb ssd and the installer slowed down to a crawl and the estimated time for completion was shown as >1 hour.
whereas when i installed the same game on a 1tb hdd,it installed in a little under 10 mins!

This means SSDs are still way behind when it comes to random write speeds.

BTW can i go ahead and get the PNY 120GB ssd? is it reliable?

That sounds like either:

1. A bad SSD. This could be for various reasons such as poor firmware, bad microcontroller design, no DRAM or SLC buffer, worn out memory (possible with old SSDs) etc.
2. A very specific case where for some reason your SSD did not have enough free cells, and trimming (zeroing free cells) had not yet happened and each cell which was being reallocated was zeroed at the same time new data was being written to it during installation. This is because of wear leveling. SSDs like to spread the data as far and wide as possible within the available memory instead of re-writing to the same cells, so the freed up cells need some maintenance, TRIM being an example, to reduce the write times. Smaller SSDs are more likely to face this than larger ones.

Even though it took longer to install the game to your SSD, you'll find that the load times will be significantly faster than the 1TB HDD installation.

Even a shitty QLC with zero buffers will do better on random writes than an HDD. The IOPS on an HDD is in an order of one or two magnitudes lower than the IOPS on an SSD. Even within the limits of the SATA interface.

Something wrong in this case as mentioned above because even the worst ssd has random read write speeds at least 20 times more than hdd.

Seagate 1TB hdd:

Kingston A400 120gb ssd:

It really sounds like the cells are being cleared and rewritten with every write operation, instead of scheduled background trimming of unused data.

Would make sense if the data on the disk is being almost constantly modified and somehow in his specific use case the scheduler is not being able to run maintenance on the disk.

May be a windows issue especially if OS is old/not updated or too new(windows 11).

I can't imagine TRIM failing Windows 8 onwards.

Windows 7 IDK about the service packs but the original version should not have optimisations for SSDs enabled by default. Manually enabling TRIM using fsutils was a thing back then.

AMD CPU prices are going down?
Ryzen 5 3500 for 12.8k on Primeabgb
Is this better price considering past prices?
And is this good time to purchase any AMD cpu + motherboard? Or should I wait?
(I can wait for longer time not in hurry )

Buy Online Intel Core i3-12100F 12th Gen Alder Lake Quad-Core Desktop Processor BX8071512100F - in India
Better choice, check i3 12100 reviews. Can consider i5 11400F at under 14k as well.
Intel processors nowadays do seem better from price/performance perspective but what about those looking to keep/run their pc for 5-6 years(or even more) because for intel based systems it is almost certain that once the 3 years warranty is over it is almost impossible to find a decent compatible mobo(processor rarely malfunction nowadays) compared to amd where even today one can buy a good B450 mobo compatible with 1st gen ryzen processors launched in mid 2017.
