I was looking at these on amazon, and decided to take some notes, and thought someone else might like them.
840 PRO Series
128gb: $1.07/gb
256gb: $1.28/gb
512gb: $1.28/gb
EVO 840 Series
120gb: $0.67/gb
250gb: $0.61/gb
500gb: $1.96/gb
750gb: $1.72/gb
1.00tb: $2.23/gb
I decided on the 250 EVO By the way.
I'm probably going to get a 1TB SSD soon.
Go ahead if you want, I wouldn't get one yet because they aren't reliable. I like WD reds, and the HGST travelstars in that respect, but I wouldn't mind a 1tb ssd if I had it backed up proper.
Hasn't there been much progress on the reliability front, then? Or is it just on higher capacity drives?
I can't imagine many people who know a thing or two about computers will want to risk data important to them on an SSD if there are still issues.
Given that Apple laptops have relied on them for years (?) now they must be reasonably safe to use.
The 840 and 840 EVO actually use cheaper TLC NAND which is only rated at 1000 writes, as opposed to more traditional MLC (3000 writes) found in the 840 Pro and most other SSDs.
I suppose larger capacities makes the limited write cycle count less of an issue, due to wear leveling.
SSDs probably are fine reliability wise, but unlike traditional HDDs, they don't often provide signs of dying - they just suddenly decide not to work from what I've read. So like always, you need to keep backups.

The biggest signs I had when my drive failed (3 times now):
OS became choppy, file transfers took longer than normally to hit full speed.
Installing an OS would fail half way through
And most recently, I could read files but I could not delete them.
The small business servers I work with are starting to slowly trickle into Intel SSD RAID setups.

Are these in a RAID setup and/or you're certain the choppiness isn't a result of having to do parity calculations or rebalancing the drive array?
But otherwise, interesting to hear!

That particular incident was my single drive in my PC.
HDDLife as been updated for SSDs, and also a program called SSDLife. Both can catch some early signs, but they are not perfect.
This is interesting I didn't know that. Most of the time though, my computers are on constantly, so in my particular case, it's beneficial to have a physical HDD, and I know that hgst and wd have very reliable failure rates, at nearly 1%. I remember reading that seagates are around 50%, and I'm not sure what Samsung's ssd failure rates are, but it wouldn't matter because everything in my case will just vs cached to ram after boot, and then it would be all HDD/ram.

Ah I see.
Wait, are your calculations correct?
Samsung 840 EVO 500GB: $245 ($0.49/GB)

Other 840 EVO:
120GB: $83 ($0.69/GB)
250GB: $150 ($0.60/GB)
750GB: $434 ($0.58/GB)
1000GB: $459 ($0.46/GB)
You didn't happen to divide the GB amount by the $ amount did you?
