We are a commune of inquiring, skeptical, politically centrist, capitalist, anglophile, traditionalist New England Yankee humans, humanoids, and animals with many interests beyond and above politics. Each of us has had a high-school education (or GED), but all had ADD so didn't pay attention very well, especially the dogs. Each one of us does "try my best to be just like I am," and none of us enjoys working for others, including for Maggie, from whom we receive neither a nickel nor a dime. Freedom from nags, cranks, government, do-gooders, control-freaks and idiots is all that we ask for.

Pic: Result from using incorrect wiring with the new fast hard drives.
Actually, I should correct something I said up above. I said a digital drive is "blazingly" faster. I probably should have said screamingly faster. I mean, there's really no comparison, as you'll see in the figures below the fold.
I made three different types of test:
— I made a real-time test by making a duplicate of a 4.6 GB file on each drive, which combines both read and write speeds.
— I ran both drives through two standard hard drive speed test programs.
— I ran Norton Disk Doctor on both, which does a full-system scan of the entire C Drive looking for physical problems.
The tests were done on a 64-bit Lenovo ThinkPad E545 laptop, AMD Radeon 2.9 GHz processor with 8 gigs memory. No other programs were running in the background.
Both drives are attached to the main bus, not a USB port. Details on how to do this are here.
SSD = Solid State Drive
The SSD drive is a Samsung 850 EVO, about $175 on Amazon. If you're plugging the SSD drive into a 3.5" bay in a tower, you'll need one of these. The HDD drive that came with the laptop is a Western Digital WD32.
Here's a performance chart from this site where I typed in the WD drive and it compared it to some SSD drives:
You can see why I upgraded to the Samsung within minutes of seeing the chart.
As I said, the numbers are so lopsided that the word 'comparison' really isn't applicable. If you're looking to give your machine a boost, this is the way to go.

Gad! Screamingly is the word! I just ordered mine. It's actually the first new computer part I've bought in years. But what a part!
Here's an example of how fast this critter is. You know that little Windows 7 logo that appears when the rig is first booting up? It used to appear for, oh, about seven or eight seconds. It now goes BLIP! and it's gone. :)
I started using these when the Crucial M4 128gb broke $200. Had SSDs in all our machines (5) for several years, switching to the Samsung EVO some time back. When I occasionally fix a kid's, or neighbor's, or a kid's neighbor's machine with a platter drive in it, I feel like I'm in one of those dreams where you're swimming in molasses.
Okay Doc, its fast, but what is the best way to deploy an SSD? I understand that there are only so many read/writes you can do before failure. Its lot, but a concern. One never defrags an SSD because it doesn't speed anything up, and it is burning read/writes. Also, an SSD drive is expensive for the size. If I were to install an SSD, I think I'd load the operating system and all program files on it, but direct MyDocuments and other storage to a spinning disk. Maybe put Temp files off the SSD as well. What are your thoughts?
As far as the life of one, I figure compared to how flaky disk drives are overall, the SSD still has the edge. And I once read an article on just how many bzillions of read/writes it has, and it's a real bunch, so I don't view it as a concern.
As for usage, I bought the 500 gigglebyte, so 50 gigs of that is devoted to the C Drive and the rest to my 'Work' partition, as that's the one I actually do stuff on. The old WD drive is just used for storage. So it all works out nicely.
Nice write-up. Switched over to SSDs in both laptops and hybrid desktop.
Got my hands on a newer core 7 machine w SSD, and wow. Word, excel, and all the office sw boot up in about 1 second.
Perhaps next you could drop some hints and tips on networking and/or "smart" things?
Nice to see you back.
"Got my hands on a newer core 7 machine"
"Perhaps next you could drop some hints and tips on networking and/or "smart" things?"
Can you explain that a bit more? There are some aspects of 'networking' that I'm pretty good at, but others, not so much. And the word 'smart' needs better defining in today's world. It could mean anything from a phone to a toaster. :)
When your HDD is full of stuff, that seems the way to go: SSD for work, and HDD for storage.
I avoid SSDs. All the ones (3) I've had have failed, apparently on the limited number of writes thing.
I'd rather keep the data with higher odds.
I mostly run stuff that's unattended though so I don't see the speed advantage anyway.
from a phone to a toaster.
Ah, you haven't seen the new HD screen interactive Alexa enabled toaster...
Those test results are just startling! I'm definitely going to look into buying one. I copy lots of large ISO files, so the 4.6 GB stat was of particular interest. Thanks for the great post!
The "limited number of writes thing" is baloney. If your SSDs are failing, there's some other reason.
I tend to agree. The number of read/writes on the things is in the bzillions. I'd suggest the brand is at fault, or maybe the power supply.
Three different laptops, all with 16gb ssd's. Dell inspiron 910 I think. They ran unattended mp3 recording Imus in the Morning each M-F, which is what ran the writes up after a couple of years.
Dr. M, I don't know where else to direct this comment, so I am directing it here. I tried to make a comment at the Fun Football Quotes posting, but it got rejected as Spam. Gringo speaking.
What the @%$&@ was wrong with my comment that it got flagged as spam?
It's a glitch in the Maggie's system, because it's actually split between two servers, and occasionally they don't sync up and it spits out that spam message. Happened to me just the other day. Simply hit the Submit button again and it should go through.
Submit again didn't work. Moreover, when I tried to make a comment at another posting, it got rejected as spam- my blog name+ e-mail + location were considered verboten. What worked was to unplug the Internet and get back on- thus giving a different location- and to have a different blog name w different e-mail.
Gringo under different name.
Hum. Not sure what to say. You left a comment in this thread just yesterday without a hitch. Perhaps you're actually a Mexican, not a "gringo", and the software is punishing you for 'cultural appropriation'?
Well, it's a theory. :)
The comment had a link+ "[quote]" Preview indicated the comment was correctly formatted, so that wasn't an issue.
But I have made numerous comments with same that have not been kicked out as spam.
This is the second time in a week or two I have been spammed. Guess the solution is to do what I did this time.
Given previous performance, I predict that tomorrow I will be able to post as Gringo.
Gringo didn't work, so blog name + e-mail got blocked w different location. I got out of Internet so have different location from the last block.
I suspect that too many previews will trigger spam. I have noticed that in Disqus [spelling]- which I believe doesn't have Preview- too many Edits [3?] will trigger spam.
Well, er, I don't think so. There wouldn't be any reason for the software to actually count edits or previews. I say we chalk it up to the classic "forces beyond our control" and be done with it. The software Maggie's uses is quite archaic and hasn't been updated in a decade.
Price. You should really mention that SSD drives are VERY expensive.
A 1TB spinning laptop drive WDBMYH0010BNC-NRSN is $60.00
For 500GB WDBMYH5000ANC-NRSN it's $45.00
A Sandisk 1TB SSD SDSSDHII-1T00-G25 is $270.00
A 500GB Samsung MZ-75E500B is $150.00
So the SSDs are about 4x the price of regular drives.
So, spending $270 to upgrade the drive on an old laptop may not be a good idea when all the other components are getting old... (fan, video, keyboard, etc...)
At least the drives can be used elsewhere if your old laptop dies...
"So the SSDs are about 4x the price of regular drives."
Yes, but they're 8x faster. So there's that to consider, no? 'Bang per buck', and all that.
And you're right about them being able to be used in a future machine. Six small Phillips screws and it's switched.
