'[OT] Help picking an SSD'

Hi all,

I'm looking for an SSD for my desktop computer. I hope someone here who has
some experience with SSDs can point me to some good products. I bought a
30GB AData SSD about 15 months ago and it failed inexplicably after 6
months of normal use. Will not buy AData again; I knew what I was getting
into, but took the risk anyway.

Requirements:

- Decent quality from a respectable brand. I don't want it failing on me a
few months down the line.
- Reasonable price. Doesn't have to be the cheapest, but I'm a student, so
I'd rather not empty my bank account.
- Size: at least ~60GB, 128GB would be good too.
- Has some kind of a warranty (~1 to 3 years?) so if it fails under normal
use, I can get it replaced without jumping through hoops.
- Must be SATA 3 (unless someone can tell me why SATA 2 is good enough, but
modern SSDs have higher than 3Gbps performance and SATA 3 offers 6Gbps).
-- Note: I'm looking to buy a PCI-E 2 (or 3) SATA 3 4-port hardware RAID
controller and another SSD of similar size a few months after I buy this
one so I can stick them in a RAID 0 configuration

Well....we do have the best product in the market, but its not in a students price range.  Ours are PCIe based products as well, not SATA

Here you go:

A thought on SATA3 vs 2…even with a hardware controller, your machine may not be able to effectively make use of the increased throughput. You may spend a bunch of extra money and not see a significant improvement in load times, etc.

If you do buy a controller card I suggest a card by 3Ware.

When SSD drives fail they tend to fail catastrophically and without warning.. Make sure you have things backed up. I recommend CrashPlan.

Having had two fail now I thoroughly recommend you only store your OS and not useful data on the SSD.  First went after a year, its replacement after only 2 months.

Seems to be an issue when the PC wakes from sleep and the drive goes into a panic mode.

I ended up buying two OCZ Vertex 4 128GB drives and put them in RAID 0 via
the motherboard's "fake" RAID. The Intel P67 RAID controller on my
motherboard seems to be surprisingly good and well supported. The Windows 7
installer detected it without even having to install the drivers (but I did
anyway). The drives work very well and I'm very pleased with the
performance. I don't think I'll need to get a dedicated RAID card soon.

I always do incremental partition backups to a separate hard drive every
two days, so even if something fails, it doesn't take long to restore to
another drive or partition and keep working until a replacement drive is
installed.

@Peter, SATA 3 makes a huge difference, especially on my system. I can do
greater than 1GB/s reads and writes (benchmarks) to my RAID 0 array at the
moment.

@David, I store everything on these SSDs and make backups every two days to
other drives. There's no point using SSDs if you're not actually going to
use them

faster better cheaper pick any 2
SSD means faster is already chosen for you.

faster and cheaper get an OCZ, with the latest firmware they seem to have stopped blue screening and general flakyness at least.
faster and better, get an intel, they have about the same failure rate as regular rotating media it seems

don't RAID your SSD's, TRIM commands won't go through the raid controller so it'll start to suck loads for writes pretty quickly

Yup, I'm aware of that, but:

1. Intel's motherboard RAID driver (alpha version at the moment) does
support TRIM over RAID 0. I'll just update when it becomes stable.

2. The background garbage collection in modern SSDs (especially the Vertex
4) is supposedly really good and will do its thing when you just leave your
computer idle for a bit. Since I leave it on 24/7, it gets all the time it
needs when I'm sleeping.

I'm not worried about it at all. The benchmarks show that in RAID 0 mode,
the read and write speeds are almost 1GB (GigaBYTE) per second, almost
twice the speed of a single SSD without RAID 0.

Even if it does somehow start losing its write performance, it would take
about half an hour for me to do a backup, full erase, and full restore, so
I don't really have anything to lose
