SSD has less lifespan ?

I was thinking about buying a used SSD from EBAY.
I can get a 250 GB SSD for 50$ with 95% + life.

But , old or new , my question is how long is it going last?

I will watch at least one movie / day in my PC.
In a month I will spend at least 10 hours playing high end games.
Most time music will be playing in background.
Every other time I will be on Chrome , browsing forums or plating videos in YouTube.
My monthly internet usage in PC is 150-170 GB.
I keep my PC on for most time.
And torrent will be downloading most time....

Should I use SSD or HDD ?
SSD for OS , App and Games
HDD for movies, videos, music, docs.

SSD life is pretty underrated. Remember, the manufacturers in general want the SSD to hit it's rated life as if it doesn't they'll catch heat for it.

Here's a -great- article where they torture tested 6 SSD's of varying types. tldr; they all vastly exceeded their rated write capacity.

Just some rough figures to think about. If you run your computer hard with a lot of stuff going on, you might have a -fraction- more to worry about, but do the math: Your average light user might write 5-10GB/day. Remember, reads don't count. A heavy user might write 40GB/day. The math:

Drive Capacity: 250GB
BytesWPD: 10GB
Total drive writes per year: 3650GB/year...


Your final comment is actually your best solution - use an SSD for OS, Apps, and Games, and a HD for everything else. Using An SSD to store videos etc is pointless since the advntage of an SSD is speed (but a HD is fast enough for playing vids etc) and the disadvntage is size (where the HD scores - lots of space to store your stuff)

As for how long it will last, chances are it will be a long time - it's not really something you need to worry about given your typical usage (though be wary of buying old model drives on eBay...)

And many SSDs (Samsung for example) come with software that amonst other things will give your SSD a 'health' reading so you'll get lots of notice when it does finally approach the end of its life.
 


I will be downloading torrent most time.... Thats why I keep my PC on 24X7.
Is it a problem ?
 

If you get a little lucky with HDDs and treat them carefully, HDDs can last 15+ years, much longer than they are likely to get used for. I have a bunch of 2-120GB HDDs, all still in working order, although I haven't used most of them for anything beyond offline backups in years.
 
Torrenting a lot could fill up the 250GB very quickly. That aspect is much more of a problem than actually wearing out the SSD.

It's true that SSDs have a limit on write endurance. But they also don't have moving parts that wear out. Depending on usage, an HDD will often wear out faster than an SSD.

Drive Capacity: 250GB
BytesWPD: 10GB
Total drive writes per year: 3650GB/year.
Total wear averaged cycles per cell: 3650GB/250GB = 14.6 total drive writes per year.
Average cell program life: 3000 cycles.
Total lifespan at 10GB/day writes: 3000/14.6 = 205 years.

At 40GB/day, 205/4= 51 years.

And that's at a conservative rating. There's a guy who's torture testing a Samsung 830 250GB drive (which I prefer myself along with Crucial drives) with 4.5PB of writes. He hammered it over about 190 days with 4.5PB writes (24TB/day!!!! WTF!!!!) before running into errors. Average program/erase for the 830 series which used the MLC is about 5000-10000 P/E cycles and it hit over 20k P/E cycles.

Well , I don't want SSDs to live more than 5 years.
Our PCs will change in that time.
I am worried if the SSDs are going to die in an year !!
 
Just as a side note, I have SSD's as the primary drives in -all- of my machines at home. The list is:

Webserver:
--64GB Crucial M4 - 36k power on hours. Zero errors.
--256GB Crucial MX100 (x2) - 16k power on hours. Zero errors.

Media server:
--128GB Samsung PM800 (old!!! lol) - 36k power on hours, one program error, wear indicator down from 100 to 95. At this rate it should be good for 600k hours of service or so. It was one of the original drives in the webserver, it was taken out for use because I needed more space.

Backup server:
--64GB Crucial M4. 42k power on hours. Zero errors.

Main desktop:
--128GB Samsung 830. 47k power on hours. Zero errors.

Main Laptop:
--128GB Sandisk MSATA. 32k power on hours. Zero errors.

HTPC:
--128GB Samsung 830. 14k power on hours. Zero errors.

The thing is though, all these are MLC drives. I'm not sure how much I like the TLC drives as they take more time to write, they can be more problematic on writes, and they just don't seem to have the robustness of the MLC drives.
