Shopping for SSD, any particular brands?

OK, I will go for a SLC then.

Hmm... Gotcha... But the OCZ does do better in most of the write categories, no?

OCZ has operating temp of -10*C which is pretty good compared to others.

I have a 32gb Patriot Warp SSD. I have not installed it in the car yet but it works great through all my bench testing and I must say that installing windows on that drive went REALLY fast. I couldn't tell you how it hold up in the long run but so far it hasn't flinched.

I just finished installing an OCZ Vertex 120GB SSD in my laptop. The drive is extremely fast, even when applying my drive backup.

I don't think you need an Intel X25 for a CarPC. You can get a 30GB Vertex for $129. Maybe even cheaper elsewhere. Or go for the older Apex series if they're cheaper. You're not going to be doing that many repetitive writes to disk in your car pc, are you? Instead, what you're worried about is read rates. I can tell you this Vertex I have boots up my Win7 laptop in about 20 seconds, maybe less. I haven't tried hibernation yet.

the patriot warp is terrible in cold weather.

Exactly, you are doing reads, not writes.

Any of these drives will be fast enough, but if you like topend, then there is no doubt that Intel reins supreme.

And small file reading is always going to be slow because of the very nature of flash memory. In a plattered hard disk you can write or read a single bit in a field of random bits anyway you want. In a flash drive, you have to write and read in sectors. For instance the old MMC cards had 16Kb to 32Kb sectors. So to change 1 bit somewhere, you had to read in the whole 16Kb, change the 1 bit, and then write the whole 16Kb back. Same thing happens on these drives, but now the sectors are ginormous in comparison. So small file read/writes will always be slower up until the speed of a platter getting up to full rpm. Just as an fyi.

Yes Windows tunning

help a lot or if you use external RAID card which have integrated RAM, this RAID card fix problem...

Yes it have better write performance. Few firmwares which have been on test units have better result in ATTO at 4.0k if I remember it has been around 10000...

As few users tell write speed in carpc is not so important(only when you do hibernate). I can tell that in windows 7 I use hibrid sleep and it turn off motherboard in ca. 3-4sec with 2GB RAM, I don't know If W7 copy whole 2GB RAM into file or only used space...

It's important to have decent write speeds otherwise your windows bootup will suffer. I was quite surprised to see my MLC SSD drive take longer to boot up Windows than a regular HDD even though the SSD drive had faster read speed throughput (117 MB/sec) -- I find it's more important to look at the small read and write performance numbers. When windows boots it makes a few small writes and this killed the performance. For fun I buffered all the writes into RAM and this fixed the long boot up times.

I had to send my MLC SSD drive back for a refund because it would not work with my carpc. It worked fine on my notebook, but none of the two carpc motherboards I had at the time (D201GLY2A and D945GCLF). My MLC SSD drive would lose it's partition table data on multiple occasions -- even during Windows installation. However it worked just fine on the notebook, just strange.

You can never go wrong with a SLC SSD drive as a choice. Keep in mind that SLC drives should cost twice the price of a MLC SSD drive when shopping around.

It seems to me that if you get quality MLC it should be fine for 99% of consumer applications.

I did a video with Intel on this topic here:
