40 or 80GB SSD

Raptors. Best fast case scenario...


FYI STORAGE FANS:

SNDK - SanDisk Corp. – Bulls are picking up in- and out-of-the-money call options on the maker of flash-based storage products once again today with shares in SanDisk Corp. trading 1.5% higher this afternoon at $50.35 just before 1:00 pm. Earlier in the session, SanDisk’s shares jumped 2.75% to hit an intraday- and new 52-week high of $50.97. Near-term bullish players purchased more than 2,000 in-the-money calls at the December $50 strike for an average premium of $1.35 apiece. Investors holding these contracts are prepared to make money should SNDK shares rally another 2.00% over the current price of $50.35 to trade above the average breakeven point at $51.35 ahead of expiration on Friday. Longer-term optimistic traders looked to the July 2011 $55 strike where some 2,000 call options were picked up at an average premium of $5.05 a-pop. Call buyers at this strike are poised to profit in the event that SanDisk Corp.’s shares jump 19.25% in the next seven months to surpass the average breakeven price of $60.05 by July expiration.

just read this report these days - infos about failure-rates for new hardisks

not working or not long working SSDs are nearly as often as broken harddisks, only Intels SSDs ( 0,6 % ) had much better failure-numbers here.

this means when having new SSDs its still a "normal" risk to get a bad one ( 2-3 % ) , like standard HDs also.

also the report say there are much more bad HDs if they have more than 1 TB.
the smaller the better they are it seems.

Intel ist den Zahlen von hardware.fr zufolge der einzige SSD-Hersteller, der besser dasteht als Festplattenhersteller. 0,6 Prozent beträgt die Ausfallrate. Die vier anderen SSD-Spezialisten (Kingston, Crucial, Corsair, OCZ) befinden sich im Bereich zwischen 2 und 3 Prozent und damit im Mittelfeld der Festplattenhersteller.

SSD Opening Multiple Work Spaces?


I'm considering a SSD in an effort to manage multiple workspaces (w/ up to 6 chart each). It would be nice to open 4-6 of these workspaces (into the cache?) and toggle them from the NT7 file menu or MA. Am I expecting too much out of a SSD here w NT7 in 32 bit mode on a 64 bit system (see below)?

System Config: WIndows 7 Pro, 64 bit, Dual Quad Core 2.27GHz, 16 Gig Ram

Looking fwd to NT7.0.1000.4 as it is said to run in full 64 bit mode on Windows 7 with Service Pack 1 and I can use all my RAM and Processor potential!!!

SSD is becoming cheaper now..
I have bought a 64G SSD at around US$90.
I have 4G RAM, AMD x4, installed with win7+NT7+TS9.

SSD will reduce load time, but not "toggle" time as most likely this is in-memory at that point and is cpu dependant.

AnAnd just did a good review of the Vertex 3, best SSD to date:

OCZ Vertex 3 Preview: Faster and Cheaper than the Vertex 3 Pro - AnandTech :: Your Source for Hardware Analysis and News

Drives will hit shelves soon. They are expensive, but this is what I am looking at personally to replace my aging 4x750gb raid 10 3ware setup.

Due to time constraints, please do not PM me if your question can be resolved or answered on the forum.

Need help?
1) Stop changing things. No new indicators, charts, or methods. Be consistent with what is in front of you first.
2) Start a journal and post to it daily with the trades you made to show your strengths and weaknesses.
3) Set goals for yourself to reach daily. Make them about how you trade, not how much money you make.
4) Accept responsibility for your actions. Stop looking elsewhere to explain away poor performance.
5) Where to start as a trader? Watch this webinar and read this thread for hundreds of questions and answers.
6)

Another option is the RevoDrives. These are SSD on a PCIe card. I just ordered one of these for a new system I am building. I went this route because there are no cables, so I can build a sys with a mobo, a graphics card, and an SSD. Done.

REVOs are 740MB/s transfer .... 8-O

I am still contemplating for REVO since I primarily run a Linux box. Only 2.26.35 kernel onwards support TRIM.

How would REVOs go under Linux is a big question?

Not sure on Linux support, but I am very happy with the Revo drive I got.

One caution though, make sure your video cards and the revo all fit in the slots you have if you have more than one video card. I used Nvidia NVS 295 cards, which are passive and only use a single slot, so no issues. My old video cards would not have worked because the passive heat sync actually took up a second slot.

For anyone interested...there are some big time Black Friday deals going on for another 2 days at Newegg on a number of SSDs...

I am probably going to be springing for one.

In some cases, I believe a SSD would, in fact, increase your actual platform's speed. Or at least increase the amount of data that it can handle at the same speed.

Case in point: Sierra Charts.

Information is written to the disk first, then read off of it to draw the charts/post data wherever you want it to be shown. (this is spelled out in their documentation, and is done on-purpose, so that multiple simultaneous representations of a market can be run off of a single data file).

My style is not that data-intense, so this is never a problem at all for me. And I notice no lag when I sometimes use a different platform right next to it (if anything, Sierra seems to be the faster of the two).

But if you needed say 6-10 different markets, each with volume and Depth of Market, your HDD would be crying for mercy & overheating alot as it wrote all of that data in real-time (I tried it just for fun, & my HDD is still mad at me).

Intuitively, it would seem that a SSD would speed up this process if you were stuffing large amounts of data into it in real time. Anyone with real expertise, feel free to chime in here & correct me if this notion is way off-base.
