2x250GB Vertex SSD's in Raid performance is crazy

Hi All ,

I recently upgraded to 2 250GB Vertex SSD HDD's and I wanted to share the speed of these monsters..

This is 504MB read and 404MB write ...... needless to say i can copy a 4.3GB file into itself in 25 seconds..

Anyone else messing with SSD's yet?

that is pretty impressive

the only thing that worries me about SSD is limited writes . i wonder if test has been done writing to same area of disk over and over to see how long it causes a failure

Same here, I don't know how long they could last yet. They are implementing a writing method in which they write all along the drive, I'm not capable of fully describing it though. We've yet to see much more of these awesome drives.


For now I have to cope with 20 minutes to copy an 8GB file :p

Well depending on the capacity it would seem that the "wear-leveling" algorithms would make the time to the next write of the same cell longer if the capacity is greater.

without the wear leveing features an ssd would die wayy to soon. not sure how short , but short nevertheless..

Heh yeah and last time they tried that it made an absolute mess of itself. SSDs are still a new technology - I'll buy in once the write capacity and wear leveling problems are smoothed out :)

So i am new to the raid area and all, but i thought RAM is what runs the programs not the hard drive ? Also what is raid and how does it work ?

RAID is an acronym to describe a Redundant Array of Inexpensive Disks,[1] a technology that allowed computer users to achieve high levels of storage reliability from low-cost and less reliable PC-class disk-drive components, via the technique of arranging the devices into arrays for redundancy.

For servers you need SLC ssd's otherwise an MLC would die pretty quick. I've been lurking on overclock.net and am very excited

The vertex are amazing, there aren't really any numbers yet on Vertex vs Summit though

If I was rich I would raid some intel X-25E's or the Vertex EX's. They are NICE. Anyways lucky you got some vertex's, however, Get windows 7! It has a built in ssd defragger that doesn't pump your ssd with voltage and kill it

I'm trying to wrap my head around that.. It reminds me of this:

SSD's don't need to be defragged, they have virtually zero seek time. In fact they purposely fragment themselves internally as a part of "wear leveling" so no one sector gets accessed too many times, wearing it out. No amount of defragging the filesystem will ever speed things up, since the SSD will purposely put things out of order again.

Pseudolobster, check pcper.com or a few other review sites, you'll see ssd's acting STRANGE. For example a new firmware will boost performance by 100 percent. Or another SSD degrades so soon after regular use its as fast as any old hard drive. Don't believe that crap everyone says, numbers don't lie, and when you consider intel took pcpers advice in designing their new firmware (might have been ocz I can't remember) its obvious something is up.

So yes I am excited about windows 7 and ssd's and for some reason it does make them go faster, hopefully new firmware will fix the need

I got 2 600GB HD, each on 100MB read/write not bad :D

This is pretty wild, it's like mechanical Ram. I still thing SSD will win this battle but only time will tell.

DataSlide

The magnetic hard disk's tenure as a critical part of the storage technology mosaic is entering its sixth decade, and it shows no sign of ending any time soon. However, certain limitations imposed by rotating media have been coming to the fore lately, and SSDs, which can in theory resolve all these problems, have long been hailed as the eventual successor technology for mass storage. If UK-based startup DataSlide has its way, though, magnetic recording media will get at least one last hurrah, in the form of a new technology called Hard Rectangular Drive.
