Disk load making my PC hot n' slow - will an SSD help on SATA I?

My laptop has had some overheating and sluggishness issues. This is because of the HDD. HWmonitor reads the drive as 50° or more, and that seems quite hot. When I try doing very simple things, like luanching an app, HDD usage hits a hundred percent usage a sticks for a while. I know that an SSD will always stay cool, but will it be lagging in performance due to SATA I? The theoretical max of SATA is 187, but the real is about 144 (using a 0.77 multiplier, common for SATA), so will the limiting factor be the interface? I can also get a HDD with 200 MB/s transfer, so that won't operate at max nonstop. Thanks.

Sadly your system only has a SATA I (1.5 Gb/s) drive interface. So you are limited on the throughput of the interface not the drive its self.

As for your problem a drive thats running hot could be the drive but it could also be the SATA cable as well. over time drive do wear-out and the custom SATA ribbon cables laptops use also tend to breakdown. So you may want to replace both here.

As to which drive to go with you could go with either a SSHD or SSD.

A SSHD is a hybrid traditional drive like a Seagate laptop SSHD. But you do need to be careful here as you'll need one of these older Seagate drives the newer version called FireCuda doesn't offer SATA I support.

For a SSD you could go with a Samsung 750 EVO.

Note both of these drives list SATA I (1.5 Gb/s) as well as the other SATA I/O speeds. These drives are called auto sense drives. Many of the drives today are fixed speed only listing a single SATA I/O speed often just SATA III (6.0 Gb/s). These fixed speed drives only work in systems which have the same SATA I/O speed.

But before you make the investment of a new drive consider the limitations of the system if you want to use newer versions of your apps. and the fact Microsoft no longer offers updates for its older OS's so you do run the risk of virus/malware/trojan infections.

So even if I did get an SSD, the system performance would still be lacking? I know that the offload speed would be limited to 144 MB/s, but I figured that it may be something else that made an SSD fast that I didn't know about. Anyway​, if you recall Seagate FireCuda SSHD vs Standard SSHD, did you ever try fixed SATA III drives on windows or Linux? Anything besides Mac?

In this case, there is no point in going to a SSHD, because I can get a HDD with near 200 MB/s transfer, which means the limiting factor is yet again SATA I. But because it won't be running that fast all the time, it should stay cool. https://www.amazon.com/gp/aw/d/B01LYNQXC...

One more thing

Can't replace the cable. The SATA is basically a slot. Like a dock in a way. The connections at the end are soldered onto the motherboard. I'm thinking the heat is because of max load all the time.

This is just a secondary computer, so it's not too important.


@pccheese - if this system has a direct SATA interface mounted to the logic board then you don't need to worry about the cable as it doesn't have one then.

As for performance yes a SSD would do wonders! But, the given version of MS Windows may not offer TRIM services which is something you do want.

Frankly, I would go with the SSHD it will be cheaper and may offer enough bang to hold you over until you can save up for a newer system (new or used).


Windows 10.

I won't be getting a new system anytime soon, as my PC money goes into my desktop. All my laptop needs is a good SSD. Besides, I can always re-use a SSD.


Here's the TRIM command for Windows 10 How to ensure TRIM is enabled on Windows 10 to keep an SSD at top performance.

Keep in mind if you system is limited in RAM Windows will leverage the drive for virtual RAM. So you may want a larger SSD if you can't up the RAM. I would recommend a base of 8 GB or RAM and a minim of 256 GB SSD. IF you are running anything heavy or need to store large apps/files then you might want to up the SSD to 512 GB.
