I understand the concept. I'm just saying that I've never seen a RAID controller that actually does it.
6 TB 24 drive SSD raid
Well, you all now know what David looks like;-)
I'm going to be putting one in my old Dell laptop which has 2GB of RAM. For what I do with it I could probably turn the pagefile off though I'm not sure that will really lengthen the life of the drive significantly.No idea on hibernation, it works well for me. I leave the pagefile on as well (no choice, the laptop only has 4GB of RAM).

What laptop has more than one drive?I put the pagefile on another drive. If your laptop only has one drive you could try turning the pagefile off, but some applications with refuse to run under this setup.

All I can say is this thing rocks. I haven't used this notebook much since installing it, or tweaked anything for it yet, but it's way faster than the conventional HD that was in here.
That pegged my CPU for a bit, but I didn't see anything abnormal beyond that. What does the computer do when it starts stuttering?Have you noticed any stuttering? If not, open up Firefox and then open up 20 tabs in a row and see what happens.

That's certainly not what happened in my test. It was completely usable. The only thing I' did was the partition alignment thing referenced on the OCZ forum before copying the old drive to the new one. I could be CPU limited though. This thing only has a Pentium-M 1.7gHz in it.Generally, your hdd light will stay lit continually until the drive can finish all of its writes. You will not be able to click on anything until it's finished. Normally under heavy writing with a mechanical drive you can still switch programs, open the Start Menu, etc. Under a long stutter with a SSD you might be able to hit ctrl-alt-delete, but that's about it.
Win XP SP2 (32-bit).What OS are you running?

Anyone have a SSD recommendation for a ATA 6, or whatever, SSD?
The SanDisk® G3 SSD: Revitalizing Existing Laptops:
Now there's a great way to extend the life of two to three year old business laptop computers, simply by replacing their hard disk drives (HDDs) with SanDisk's G3 2.5’’ PATA SSDs. By boosting the laptops' performance and increasing their reliability, SanDisk G3 SSDs help to improve end users' overall computing experience at a fraction of the cost of a new laptop. This results in greater satisfaction on their part, along with cost savings and enhanced productivity for the organization.
SanDisk has announced a new batch of solid-state drives that couples low prices with surprisingly decent rated performance. The new SanDisk G3 SSDs start at just $149 for 60GB of capacity, and the company claims "anticipated sequential performance" of 200MB/s for reads and 140MB/s for writes. Not bad at all.
The G3 series also includes a 120GB variant priced at $249 and a 240GB flavor with a $499 price tag. According to the press release, all three models should be available in either 2.5" or 1.8" form factors and with 300MB/s Serial ATA interfaces. SanDisk also intends to release 2.5" G3 SSDs with parallel ATA interfaces in mid-2009.
As one might expect in light of those prices, the G3 SSDs use multi-level-cell flash memory instead of the more durable (but higher-priced) single-level-cell variety. That said, SanDisk claims the 240GB drive should be able to withstand 160TB of data writes, which is supposedly "sufficient for over 100 years of typical user usage."
Generally, your hdd light will stay lit continually until the drive can finish all of its writes. You will not be able to click on anything until it's finished. Normally under heavy writing with a mechanical drive you can still switch programs, open the Start Menu, etc. Under a long stutter with a SSD you might be able to hit ctrl-alt-delete, but that's about it.
What OS are you running?
If you have time to screw around, pull a backup image and then install SteadyState and see if it feels faster. I was amazing with how much faster my system was after I installed it.
Another Publications Reports Unrepeatable Numbers from Repeated SSD Benchmarks
February 13, 2009 - an article published on PCPerspective.com reported declining performance in successive benchmarks of Intel's fast SSD.
The article mistakenly (in my view) attributes this to fragmentation. But the more likely cause is halo effects and poor garbage collection performance.
After nearly two years of testing Hard Disk Drive (HDD) and Solid State Drive (SSD) products, you might presume that most of the bugs have been ironed out in regard to test tools and SSD firmware. This is not the case, even by a long-shot, as any early OCZ Core series owner will tell you. Problematic firmware aside, testing SSD technology has become a real challenge... at least if you're trying to do it 'right'. That's the point of this article, and to get you to better understand the problem, I must take you through some of my own experiences.
Regardless of your position relative to SSD products, whether you test them or use them, every page of this guide will detail the problem behind our favorite technology. Most of it isn't pretty, I'll warn you now; but every single word is worth reading.
In this article, Benchmark Reviews sets out to detail the performance differences between SSD products attached to the JMicron JMB322 host-based controller and the Intel ICH10R, but instead discovered a larger problem. While read and write performance can sway unpredictably between SATA controllers, the most disturbing subject is the inconsistency between test tools. One version of ATTO Disk Benchmark can record result different from another, while HD-Tach gives different results on the same version and driver. Please read more to learn of the pitfalls and perils when testing SSD's between platforms.
Please join me as I confess my frustrations in detail, and educate you on my test miseries before you are forced to experience them yourselves.
New Improved SSD Formula!
news flash - Fast symmetric R/W IOPS high endurance, MLC SSD, with 3 levels of wear-leveling, massive over-provisioning, write attenuation and fast garbage collection provides competitive alternative to RAM SSDs...
do you understand the list of ingredients in the solid state drive headlines?
SSD Garbage Collection is an important background process in flash SSD controllers.
Some editors and software vendors (who don't understand flash technology) mistakenly attribute a long term slow down in some SSDs to fragmentation - when really the issue is the ratio of resources allocated to Garbage Collection.
In well designe products which have reserved enough CPU power, internal R/W bandwidth and over-provisioning this "performance degradation" does not occur - or is minimal. For example systems from Violin Memory.
The term Garbage Collection was 1st used in 2002 - in an article we published about flash SSD reliability. Here's the definition below from that article.
The "Garbage Collection Process" eliminates the need to perform erasure of the whole block prior to every write. The "Garbage Collection process" accumulates data marked for erase as "Garbage" and perform whole block erase as space reclamation in order to reuse the block.
The performance impact of fragmentation on HDD performance is well known. Flash SSDs don't suffer from a dropoff in performance due to fragmentation - but there can be a similar performance droppoff over time due to the lower availability of pre-erased blocks. So when benchmarking a new flash SSD (which is initially erased) it's important to take this factor into account.
The 64GB Transcend PATA SSD I put in my old Dell laptop seems quite nice so far. How big of a drive are you looking for?I really mean ide, but PATA is somehow the new name?
I was actually wondering if a RAID controller with some onboard cache could give SSDs good small-file performance.
