That was just something I found while searching. If you want to see the whole deal, you can look here on page 89....

Is anyone planning to but a Z-Drive R2 p88?
8-way RAID-0? DUDE! Not for sale anywhere ATM. Any declared MSRP? I'm all over that....

$4500 for 1TB at the moment. I'll wait until a reputable vendor carries it.

Can you spot the oxymoron?

Something very similar happened in about 2002, when everybody everyone started putting USB 2.0 stickers on products without elaborating that you can implement USB 2.0 without the 480Mbit Hi-Speed part of the spec.
Now in that case the literature does say 3Gbps, but who the hell knows what was going on with that. As I said, with an X25-M in a Thinkpad, it's plenty fast regardless.

Has anyone here had a failed SSD yet? Besides, in this world of cheap storage, backups are plentiful.

"Super Talent today announced the launch of a brand new compact digital storage product line-CFast storage cards. Just like the traditional SD card and its enhanced version, SDHC, the CFast storage card, with SATA interface, has improved, unmatched write/read performance speeds. Super Talent CFast has a bandwidth of 375MB/s which is four times more than the fastest High Speed 600x (90MB/s) CompactFlash card while still keeping the small original CF mechanical form factor. The new CFast storage card breaks the speed bottleneck between the SSD and the device by using a SATA interface. Super Talent has clocked these CFast cards at up to 200MB/sec read speeds. With Super a Talent CFast storage card installed, there will be no waiting time for the camera to catch up, and it will be much swifter to view pictures on a camera or to copy them to computer. "
Hadn't seen this before. SATA data/power whilst retaining the CF form factor. If those speeds are actually true (200MB/sec) that really would be something.
Also we have some new HD camcorders that will record 50mbit/sec mpeg2 at 4:2:2 direct to Compact Flash storage:

A big save compared to previous efforts which used SxS type cards.

^too expensive 4 what u get...Red Scarlet 4 the win!
I can't keep up with the ever changing models OCZ keeps putting out on a daily basis
They're all too expensive any...just got to wait for memristors to come to market in 3+yrs for some significant cost competition.

SSDs are exploding like crazy this year. There are so many brands but only a limited number of controllers and flash memory manufacturers. Is there a list of what is what? I have low confidence in the weird ones.

I have the same problem. I'm pretty sure the Vertex and the X-25 aren't the best available, or the cheapest, but they do work as advertised so I'm just going to stick with them. From what I've read, the C300 is decent as well.

I'm pretty sure the OCZ Z-Drive I have will beat it. Is there a particular test you would like to see?

I don't have a C300 or I would try it out.
ddrueding

Yep, those. I don't have any yet, but if anything commonly available is close to an X25-E, it would be one of those.
Who are these guys?
ddrueding
Fixture
They are one of the very few chip designers for SSD controllers, theirs are supposed to be the new hotness. IIRC, the Vertex LE was the only one out there last time I looked.

That is a Marvell controller (Marvell 88SS9174-BJP2 SATA-III)

Their SF-1500 controller can do some very interesting things in terms of on the fly data compression etc, it appears to switch between different methods depending on workload. From what I understand it's expense generally will relegate it to enterprise roles but it seems to have no peer.

One of the side effects is that it can have issues with already compressed files (might not bode well for .NEFs and JPEGs etc).

My speculation is that we won't see much of the SF-1500 outside enterprise devices, or that limited edition run of Vertex drives. A way to package MLC and get years of enterprise life out of it.
They have the SF-1200 for "Consumer" apps, but I don't think that's going to cut the mustard for performance seekers like ourselves.

I think we will see more of the Marvell controller in forthcoming products. In my view a good thing to get these things fleshed out in mass market quantities.

And we have our first failure! No warning or SMART notifications I assume? Any word from Intel?

I can't even figure out where on Intel's site to submit an RMA for a storage device.

Yeah. Guess I'll call tomorrow. Their web-based systems don't appear to be able to deal with storage stuff yet.

Which one did you use? I had a transcend PATA SSD and got fed up with the Jmicron stuttering and yanked it.

Bummer.
The user shipped the machine to me. I'm going from the date he started bitching that it wasn't booting.
Which, hm, actually is a month. Weird.
I'm almost positive the drive is a G2. I took steps to keep SSD performance up, like moving the swap file and Documents and Settings directory off of it. I can't say for sure at this point that this is a premature death or if my user killed it somehow with overuse.

This one: http://www.ocia.net/reviews/kingspecssd
I am not noticing any stuttering. I am seeing about 78MB/s reads with it. Not bad given the interface.
Huh? Isn't having a fast page file and temp files one of the main reasons for having an SSD? Mine are constantly reading, writing, wiping etc. The 32GB X25-E is near 12TB written in 15 months or so of use. The X25M is much newer and more lightly used.
