I'm thinking of getting my first SSD drive and wanted know anything to avoid or watch out for. This would be an upgrade to my primary OS installation drive which is some old 75gb IDE 5200rpm drive.

you should put your OS on a zip drive that way you can load dirt like wallzy

These tips helped me a lot!

Direct and clear with the instructions. Nice. I'll be using that when I get my ssd come tax time.

Thanks Sean! Perfect!

You didn't specifically state win7 or win8 in the OP, but when looking at the article Decepticon linked to (great article btw) and then looking for the Disk Defragmenter, i found that in Windows 8, they now call it "Optimize Drives" and it will automatically run defrag or TRIM commands on a disk depending on the type, normal hd vs ssd.

I was pretty sure he has Windows 7.

Win 3.1

I have a pair of SSD drives to part with if you are interested.

No offense Tibbs...but purchasing a second hand SSD drive is NOT recommended.

that's pretty harsh. Although SSD's have a maximum lifespan that is probably shorter than most traditional hard drives (though that is debatable since my exp shows traditional drives can either last a few months to 8+ years and you never know which you'll get) , the performance degradation of a used SSD can be resolved with a secure erase.

I don't see how that is harsh. I wasn't trying to say anything bad about tibbs I was just saying that you really don't know how the hard drive was used. Were they defragged?....more than once? Did tibbs know to turn OFF scheduled defragging in Windows 7? That will surely kill a SSD's longevity. Now if they are brand new, never been used SSD's...by all means save yourself some cash and get them from Tibbsy!

Also, I am not speaking of performance degradation. I would think if he got a used hard drive or any hard drive he would erase/format it before use. I was talking about the longevity of the drive. It it entirely possible that the SSD's in question are some of the first ones available with very old FW and older SSD technology behind them....which did have longevity issues.

I was giving advice to Czar....what he does is his choice.

eh I would be more worried about it showing up with pedobears all over it.

Bit of a necro, but it falls under the "SSD question" topic so it's okay if I post here.... right?

Saw that Best Buy has a good price on 250gig samsung 840 evo drives. Comparable to Newegg, anyway. Sooooo I got my girl to buy it for me, got it a day later, got everything set up and installed and tweaked and junk. I check the performance benchmarks in the "samsung magician" software and my sequential reads and writes are hovering around the max for each (539/540 read and 500/520 write), but my random reads and writes (IOPS) are quite a bit lower than the maxes for each. Reads are about 48k/97k and writes are about 40,500/66k.

My question is should I worry about those random read and write numbers? The thing is snappy as hell and gives me about a 10-13 second boot minus bios post and password entry so I'm guessing everything is fine, but would I really see a real-world benefit from increasing those numbers... and how would I do that, anyway?

If I remember right from an install I did of these Samsung EVO's a couple months ago, there is a setting in the Samsung software to align your partition to the nand boundaries (can't remember exact wording). Should you worry about it? Yes. Aligning your partition to the nand boundaries will mean that when you're doing those random writes to the disk it's occurring in the same nand cell and not spread between two. When nand gets overwritten it's not just a straight up re-write. It needs to read what's currently on the cell (if anything) erase the nand, and then write your data, so a three step process. If it needs to change a little 1KB file (writing to a log file for example), an aligned drive will take three operations to do the write whereas an unaligned drive could be doing six+ operations for that little write. It's something called write amplification. There are methods built into almost all SSD's these days to overcome the effects of write amplification, but it's always a good idea to do what you can for performance.

For a good (but long) read, take a look at Anandtech's old articles from when SSD's were still something brand new. He does a fantastic job explaining how SSD's work and what makes them different from hard drives (and what that means to performance).
