trying to choose an SSD - drowning in choices

post #1 of 8
Thread Starter 
i just about finished assembling all the parts for my new build (1090t+noctua-d14, asrock870, gtx570, ripjaws, seasonic x650), and since i ended up getting great sales on the parts i decided to get an SSD now instead of later on, as originally planned. i'm gonna use it for OS and a select few games, so i don't need anything larger than the 60-80gb range (under 150$).

as usual with stuff i know nothing about, i started reading on-line in major sites (anandtech, tom's, canucks, guru3d, etc.) and in the forums here, and i have to say it's the first time that even after all this research, i am completely flustered with the SSD technology/market. there's too many products! and controllers! and opinions!!

i was hoping you guys could help me sort it out and help me choose one that i'll be happy with. i don't HAVE to have the best performer in my range, i just want to know i got a good product, and i can't decide that on my own. should i concentrate on SF? TRIM support? benchmarks?

on top of that, there's the (relatively) new 6gb SSDs, and i also read that soon PCI interface SSDs will be out. my new mobo has 6gb, should i get a 6gb ssd then? should i wait for the pci interface?

sorry if i'm a bit all over the place, hope it makes some sense..

Hey, I'll try to simplify the SSD landscape a bit. You've seen the benches, I'm not gonna get into them. These are just a few conclusion based on the reviews you may have read already.
1. All current SSD have TRIM.
2. If you can't use TRIM (OSX, RAID, etc) what matters is how aggressive garbage collections is. SF has amongst the most aggresive, Indilinix less so and Crucial even less so. Low end controllers like Toshiba's should only be used with TRIM since they have slow garbage collection.
3. The importance of TRIM/garbage collection depends on how much the SSD will be used, the more the SSD will be stressed the more TRIM/GC is important. For ex: in a lappy the disk is used less, if you have enough RAM to disable the pagefile (or move it on RAM disk) the SSD is used less, if you optimise the OS for an SSD the disk will be used less, thus it won't need aggressive TRIM/GC so much
4. What limits the performance of a system/OS disk isn't the maximum sequential read, but the minimum random write speed (or radom IOPS). If you're gonna get a sub-100GB SSD it's likely you'll never copy tenths of GB of big files to actually notice the sequential read/write speed advantage of SATA 6Gbps.
5.Performance
*SF: best random read/write speed, sequential speed around 270MB/s, aggressive GC
*Indilinx: close second read/write speed, sequential around 270MB/s, less aggressive GC
*Crucial: Indilinx-like random speed, 380MB/s+ sequential speed (on SATA3 mobos) and even less aggressive GC; some wouldn't recommend them on non-TRIM environements
*Intel: good/great random speed, low sequential write speed ~80MB/s. They were a good choice before SF appeared. Bullet-proof GC.
*Toshiba, others: since they have TRIM they can't be that bad, but they have weak GC to compensate some flaws in the controller (high write amplification). I would only buy such and SSD if it were (much) cheaper, lower power and only for a laptop.

great feedback, thx! reps

so if i got it right- if i intend to just use the drive for OS and a few select games, my biggest concern is to make sure i get a SF for random? if that is so, does anything particular drive stand out? vertex 2? pheonix pro?

EDIT: just found and read maximus' post in another thread here (http://www.overclock.net/ssd/895550-...ed-advice.html) which basically explains why the C300 is even better than SF (4k speeds mostly if i got it right). however, since c300 speeds scale as volume increases, and i'm aiming for the lowest end, should i still get the C300 over a SF drive?

Crucial C300, $135:
http://www.newegg.com/Product/Produc...-357-_-Product

OCZ Vertex 2E, $125:
http://www.newegg.com/Product/Produc...-394-_-Product

I narrowed my choice down to those two and chose the C300. The C300 has like 20% faster 4K reads, which results in most things opening faster. Go with the Vertex if you want sequential write speed, useful for pasting/installing big files.

well you did leave out the 3rd player-the Samsung drives are looking pretty sweet as far as performance and price.Time will tell how well they stand up to SF and the C300.

true, tom's said pretty much the same thing, they seem like all-around great performers (http://www.tomshardware.com/reviews/...d,2783-18.html)

i think i'll go with the c300, since my downloads drive would be my WD anyway, so no big files movement expected on the SSD (except for the occasional game uninstall/install, very negligible i think).
