Ridata Launches New 32GB SATA SSD
Advanced Media, manufacturer of the popular Ridata brand is making news today with the announcement of its 32GB 2.5" solid state disk (SSD). The new 32GB SSD is an ideal option for mobile computers and has a MTBF of four million hours. Read speeds for the new drive are up to 60MB/sec while the write speeds are up to 48MB/sec. The new Ridata lightweight SSD will be offered in both ATA and Serial ATA interfaces. The 32GB model will be available in the coming weeks, while a 64GB variant will come to market in late November. Pricing has not been announced for either part, but expect pricing of around $400 USD and $1,000 USD respectively.

Maybe we'll see a manufacturer with $200 pricing in the near future. I'd certainly pick up a pair of 32's at that price :D
It has a MTBF of 400+ years :p.
Speaking of which, how do they test that?
Its just expensive. Speed could be a little faster though.
4,000,000h=166667days=456years, but that's not true at all, here's some reading
www.storagereview.com/guide2000/ref/hdd/perf/qual/specMTBF.html
Depends really how much it's got warranty, it should last that period, but as we all know even that isn't granted. Read somewhere someone using a Flash to IDE adapter and the Flash card as swap only lasted few weeks (can be wrong, but very short time anyways). We don't know until someone actually uses one intensely, how much punishment they can take.
Those flash cards are an indication how long the drive would last, if it didn't use error correcting mechanisms and writing on different parts of the memory all the time. Don't know if they help if the drive is almost full and it can write the new data on only a small part of the drive. Anyways I'm not convinced that these will last longer than regular hard drives. Sure they don't have anything mechanical braking, but the read/write cycles are limited still.
EDIT: here some more info from wiki
"Flash based SSDs also have several disadvantages:
Limited write cycles. Typical Flash storage will typically wear out after 100,000-300,000 write cycles, while high endurance Flash storage is often marketed with endurance of 1-5 million write cycles (many log files, file allocation tables, and other commonly used parts of the file system exceed this over the lifetime of a computer). Special file systems or firmware designs can mitigate this problem by spreading writes over the entire device, rather than rewriting files in place."
en.wikipedia.org/wiki/Solid_state_drive
For a laptop this propably isn't a problem, read/writes are wery limited, but take a gaming machine and couple hours game session might do days worth of wear and tear to the disc (don't have any idea how much data is written, but as loading times are really long in Battlefield for example, I bet alot).
Also, I doubt those flash cards were using the top grade flash like the Wiki mentioned. Most are intended for camera or portable storage use.
I dont think even the high performance flash cards intended for cameras reach anywhere near 60mb/sec
I was commenting on how the quote from storagereview.com was trying to compare an SSD intended for drive use (like the Ridata drives) vs. a card in a flash to IDE reader (in other words, "camera grade" CF, SD, etc).
That flash card could been low-grade, high-grade, etc, but probably not the endurance grade flash going into "hard drive" SSDs.
If it was that easy I could RAID-0 (4) 16GB CF cards for about $600 (with adapters) and end up with about the same speed and 64GB.
