Basically depending on usage you may get around 10-20 years out of a current SSD lol.
They wont necessarily die out fast because they are limited on space. Firmware is the main thing when it comes to NAND life. Depending on how often stuff is being cached and rewritten will determine the general life of the drive.

Even then, there are multiple parts to any drive that can fail and cause a drive to fail prematurely.

I will definitely read that buyers guide.

10-20 years? That's decent I suppose. As long as after writes are dead, I can make an image of the disk and toss it over to a new SSD or whatever they're using in 10-20 years (180$ for a Samsung 840 Pro that lasts 10 years? It's safe the say that the 180$ did it's job.)

Also, I'm not really saying that it'll die out faster due to smaller capacity, I'm saying it'll die out faster because it's being used as a cache or a buffer, which, by design, is meant to be written to many times just to speed things up.

Either way, looks like that takes out my Hybrid Drive option since the cache will die out faster than an SSD (unless they did something special to it) and lord knows I don't need no 750 GB of HDD space.

Looks like I'm down to just two options: SSD or a trusty High-RPM HDD.

Choose whichever you want. If you want a SSD just dont get a crappy one, stick to something like that 840 Pro, Intel, Crucial, Plextor, or something like that

HDDs are extremely slow to me now. Even 2 Samsung F3s in RAID 0 are slow as heck compared to my SSDs. I have a laptop with a HDD and really am missing my SSD in my desktop when i use my lappy. However, that is how I feel, there are others who feel that there isn't much of a difference...I think they may be crazy tho.

When I work on my fiances rig, it's going from a 64Gb 830 to a 74Gb Raptor. 10k, but still slow as cement, and the seek noises seem to keep getting louder...

And if your really paranoid, get a good brand, and set over-provision to a higher number. I don't know if this would extend the life of the drive as a whole, but I figure it would at least give you more fresh cells to work with when the time comes.

How do I "set" overprovision? Isnt that handled by the manufacturer?

I was also meaning to ask. Since SSDs are just a series of NAND flash chips in a series, would it be possible to take a 256 GB SSD (-cough- Samsung 840 Pro -coucgh-), partition the whole thing down the middle (128 GB), and RAID 0 the partitions since technically, the physical parts of the SSD are seperate and do operate independantly of one another...

A RAID 0 SSD-in-one would be pretty sweet... Plus, 128 GB for me is plenty.

SSDs are already set up similarly to RAID 0 internally. Files are fragmented across different NAND chips so they can be used faster.

To over-provision just go ahead and make a partition smaller than the drives capacity.

SSDs are already over-provisioned ~7%. However, the more the merrier.

Can I RAID 0 the RAID 0? Or no?

And ohhh so that's how I can overprovision. Understood.

Only if you get another drive.

This is more towards a gaming desktop.

I've been having some ramdisk fun the last few days. I have a 2nd 16GB kit this week (32GB total) before I sell one of them.





Planetside 2:
1st load after boot/reboot


after everything has been run once:


(click to watch full screen at youtube)



ArmA 2:

More A2 drive comparisons in the spoiler if interested. Warning: Spoiler! (Click to show)
some older ones SSD vs HDDand an oldy from 2009 comparing a raptor to a 7200 HDD


ArmA 3:


As for RAID 0 SSD's, maybe, but I don't think they would be worth it in RAID (especially when you take into account the double chance of failure of having your data on 2 drives). In most games there is little difference between a SSD and Ramdisk and a ramdisk is easily 10-20x the speed of an SSD.
