Question What is slowing down the boot time on the Samsung SSD compared to the WD Black ?

[relentless612]

I have a PC with a Samsung I believe 980 Evo gen 3 on a mini ITX motherboard and 3600 CL 18 RAM and one PC and a Western digital 770 gen 3 on atx even though the full ATX motherboard is newer and has more bloatware on it is still boots a lot faster is that due to the the storage the ram the motherboard but it seems like a fresh install of Windows should post faster than one that I have been using for 2 years that has all kinds of programs on it

Software, startup, settings, RAM.

There is no real difference between the two drives.

Your difference is from other reasons than the drives.
Exception... If one drive is near full, it can be very slow.

The performance of the cpu makes a difference.

You don't mention the capacity of your WD SN770. As usual, the 250GB version is slower than larger versions.

According to this review, the SN770 is Gen.4, not Gen.3.

It gives the speeds of the various capacities as follows:-
1). 250GB Sequential Read 4000Mbps, Sequential Write 2000Mbps
2). 500GB Sequential Read 5000Mbps, Sequential Write 4000Mbps
3). 1TB Sequential Read 5150Mbps, Sequential Write 4900Mbps
4). 2TB Sequential Read 5150Mbps, Sequential Write 4850Mbps

If, say, your 980 EVO Gen 3 is 1TB and your SN770 is 250GB, you might notice more sprightly performance from the 980, simply because of the larger capacity allowing more channels between controller and memory.

I'm assuming both designs are DRAM-less, but if one contains DRAM and the other doesn't, you might spot the difference.

Check also if both SSDs are running 4-lanes and not 2.

Is your SN770 running on a Gen.4 bus or a Gen.3 bus? That's assuming it's Gen.4 capable.

In terms of boot times, if you have additional PCIe cards with their own BIOS, e.g. LSI HBA, 10GBe NIC, they can add a significant delay before the system loads the OS.

Best bet is to run benchmarks on both drives and compare results.

Unless your seeing the spinning circle waiting on the OS to be ready to use I think your seeing a difference in the time it takes the motherboard to go through it's self test.

Task manager/perf/startup.....what does bios time show for each pc?

 

[Misgar]

You could try running one of these programs on each machine, to get a break down of which section of the boot cycle is taking longest to complete.

If your new PC boots slower than your old PC, it might be the initial "memory training" that sometimes occurs, the first few times you boot up.
