Weve always built systems with my dad but this time his emotionally or nerves get tested and yelling insues. We argue yell. So he is 70 he didn't want that.

He bought a POS www.cyberpowerpc.com . 1600 dollars for a Gigabyte mobo that is nothing special. 8GB RAM 500GB hard drive. 128GB A-DATA POS SATA3 SSD that does 375mbps. I told him to get my same video card.
The case has front usb 3 port and what not which is cool I guess.

Anyhow I launched Crystal yesterday on his machine cuz it felt sluggish.

I mean he has a Sandy and my computer is soo much faster. His bootup is about 40 seconds. His PS CS6 launches in couple seconds , about 4 seconds.

My boot up is 17 seconds thanks to 010G firmware. PS CS6 launches in 1 and half 2 seconds. His other apps open instantly. I mean you can tell its a SSD inside but something didn't feel right.

So I launched Crystal info and it said 97 percent,,, and it was figure on degration or wear and tear. Then I tested the speed with crystal disk and it was 315mbps. Yap it fell from 375mbps pos sata 3. when it should be 480MBPS if he bought a quality SSD.

So crystal shows 97 percent and it shows the figure in the wear and tear degration. It's much slower then when it was new.

Is there anything that can be done to take him back to 375mbps. I told him to call their 24/7 free lifetime support and say the SSD is degrading and ask for exchange... gosh a-data is soo cheap. 375mbps on sata 3 is sad and means the whole ssd is junk. gl

AVOID all a-data products. CHEAP CHEAP CHEAP and that is the fact!

All SSDs degrade in time.

How old is that PC/SSD, how long did he have it ?

Is a S51x SSD, by any chance? If so, while he may have not gotten a great deal on the computer, that would be perfectly normal, expected, behavior. If it was an SP900, FI (128GB), I would wonder if TRIM weren't enabled, and would question what was causing the 3% wear. Might as well make sure TRIM is availabel and functioning, anyway.

I honestly doubt anything is wrong, except for buying cheap parts. This kind of long-term behavior from many SSDs would be among the reasons that Plextor, Crucial (sans V4, which I would like to see go one sale, to snag a few), and Samsung drives go on sale for what SF drives go for every day.

Thank you brother for long great reply. Yes he has TRIM enabled according to Crystalinfo

He is only 3000 hours useage ? Has had it about a year.

Cuz he puts his comp to sleep whenever not in use.

Degrading 100% -> 97% in a year is pretty good.

Theoretically it will reach 0% in 33 years.

How full is the drive? (They slow down in steps when they're more than X or Y % full)

If he's got plenty fast launch times, but his boot is slow, it sounds like a hanging driver, not an SSD problem.

Nice math work LOL thanks hddd1.

Well the thing is as that percentage goes down the speed of the SSD gets slower and slower... so 3 percent would be 10mbps maybe ya know :confused:

No, the speed won't go down as it wears, until it near the very end, at which point the reported life should have already been 0% for some time.

What slows the SSD down is mostly the growing complexity of mapping tables, and fragmentation of data. At some point, you have to make a trade off between wear and performance. Some of the fast JMicron SSDs chose performance, and some users have had them die on them in a matter of a few years, because of it. SF chose to be more cautious with writes, which is basically the other end of the spectrum, and performance degradation over time, which can't be fully cured with background GC or TRIM, is a symptom of that. What TRIM can do that helps is tell the SSD about more space that might be less fragmented that it can use for writes, provided there is enough space to do anything with.

Other makers, not using SF, have chosen to take a middle route, with performance drops during heavy use, and WAs that are low enough, but not extremely low, and to use better bins of NAND. Part of the issue is that SF predicted that everyone would want to use lower quality NAND, so they went to extremes to reduce WA and provide added redundancy (RAISE), which would have provided better value for their customers, compared to paying much higher prices for better bins. In the end, the market mostly chose to use better NAND, anyway, so it ended up causing issues for nothing (Samsung's 840 is the first one out there to use fundamentally 'worse' flash).

On the bright side, it's not likely to get any worse.

It has 22GB Free my friend...

On a 120? That's a tight fit. The ones I've seen charts for start to slow down at 25% or so full, and get a big dropoff around the 75% full mark. (You're over 80% now.)

Get that "free space" number up to 40GB and see if that helps. (Part of my solution for my 90GB SSD was to disable shadow copy. Since I had a restorable image on my NAS and all my data files were on a platter, it was a quick 6GB.)

The drive is getting full. Thats why the speed is coming down to a crawl. Disable hibernate in cmd prompt (Powercfg -h off) and lower the overall page file down to 2gb.


EDIT: Also lower the system restore file size.

Oh no kidding. So if he were to free up the space which I dont think he can to 40 or 50mb then it would go to 375mbps and be as fast again,,,, sighs...

That is not good news for 128GB owners cuz you already start off with 110mb then you have to have 40mb non useable,, something doesnt sound right......

My Rig is complete as far as OS and apps and DAW and Games,, I have 14 games installed right now,, not max3 tho... and I have 151GB free and since I went to 010G I swear to the holy land that the SSD has gotten faster, I mean a-data has a poor TRIM I bet...... but good info....... thank you

My dads box has no page file he has 8GB ram its enough. page file disabled.

hibernation could have played a role in this. thanks for the post.. gl :colbert:

Besides performance degradation and free space, something else to consider with "rated" and review benchmarks is that they are done on an empty secondary drive. If you are benchmarking on your system drive, performance will naturally be lower.

I'd actually like to meet Tweakboy's dad. lol Tweakboy adds flavor to this place, "devistating"ly too much at times, as the average computer user... with a cool DAW.

Tweakster, please re-enable your Dad's page file. He just called and told me you are nuts to disable the page file.
