Solid State Hard Drives
I didnt even realise you could get Solid State drives big enough to actually use as a normal hard drive until a few minutes ago when I saw that Klienma was using one for his Windows 7 PC but now that I have discovered this... I want one!
But then I only want one because they are apparently a lot quicker than your standard hard drive. However, on the Crucial website it states that their SSD drives have a transfer rate of up to 200 MB/sec but I thought normal hard drives had a transfer rate of much higher than that?
So I have a couple of questions:
1. Is an SSD drive really going to be much/any faster than my 10,000 RPM SATA hard drive?
2. Do you need any special controller or connectors to use an SSD drive or will just a normal SATA cable do the job? Also, what about Windows, does that require special drivers (like you do for a RAID hard drive setup) ?
3. I'm sure I had another question but I've forgotten it now...
Thanks
Chris

Re: Solid State Hard Drives
SSDs have been around for many years, and were mostly sold by storage vendors such as Bitmicro and others. However, non-volatile memory, usually flash, has been far too expensive to create storage products that can
a) offer sufficient capacity for desktop or mobile use and
b) be reasonably priced. Although flash-based drives now have capacities between 8 GB and 32 GB, they are still a bit away from the sweet-spot capacity points, which are 160-200 GB in the desktop space and 80-120 GB in the notebook market. A 32 GB flash drive is also three to four times more expensive than a conventional hard drive with three to four times the capacity.
While googling, I found these interesting links which you might want to go through...
Instead of storing data on traditional hard disks, solid-state drives use large blocks of flash-based NAND memory, which means these drives have no moving parts to malfunction over time. With no physical platter to spin like traditional hard drives, SSDs are faster at accessing data, and they also use less power and generate less heat.

Re: Solid State Hard Drives
I've also just ordered Windows 7 and from reading this article http://hothardware.com/Articles/Wind...alyzed/?page=3 it looks like now may be a good time to get an SSD drive as Windows 7 makes better use of them than Vista...
After reading the reviews on this SSD drive http://www.ebuyer.com/product/167203 I'm very tempted to get it, its just hard to justify spending £250 on it

Re: Solid State Hard Drives
Koolsid, that article you linked to that says they are not much different in performance compared to normal hard drives is from 2007. Everywhere else I have looked has said that they are a lot faster than platter based hard drives so I'm assuming they have improved over the last couple of years?

Re: Solid State Hard Drives
Ah yeah sorry, I just saw the bit that said "no clear winner"
I'm tempted to just go for like a 64 GB one that is much cheaper, then I can just have that as my primary hard drive that Windows boots from and still use my current 2 hard drives as data storage. Sound like a good plan?

Re: Solid State Hard Drives
168.4625 GBP
1AUD = 0.561545 GBP
1 AUD = 0.915780 USD
Which makes it 274.734 USD which is approximately 25$ less from the base price of $300.00
I still feel it is very expensive but then good things don't come at a cheap price nowadays

Re: Solid State Hard Drives
You can find 64GB SSDs for about AUD220+ or you can pay over 1k for an Intel drive of the same capacity. It all depends on what you are willing to spend and why you need the SSD (for performance, or just for a silent PC)...

Both use the same flash chips internally, however SSD's take a SATA/SATA2 connector and are plugged directly to the HDD controller on the inside of the comp. whereas flash drives/pen drives are plugged in via usb of which the usb bus is significantly slower than SATA (or even IDE for that matter).
SSD's are physically bigger than flash drives but can still be carried in your back pocket should you want to carry it around.
Slightly off topic, they do have 256GB flash drives out now, I'm currently thinking of getting 32GB flash drive because the price should lower to less than $50 US soon.

Re: Solid State Hard Drives
Toms Hardware is always a valuable resource for this:
http://www.tomshardware.com/reviews/...ware,2461.html
Oh and for data recovery question, TRIM is something you may want to read up more on:
The TRIM attribute of the ATA data set management command synchronizes the operating system’s view of deleted files with those that are deleted, but not erased on the drive. TRIM tells the SSD which data blocks are no longer in use. This helps stabilize the performance and health of the SSD over time.
I should be getting 2 SSD's in January for my new system.Hopefully when VS 2010 is RTM'd I will have it finished for a Windows 7 + VS 2010 + Office 2010 system running on a quad core with 8gb ram

I didn't address this because I don't know, I'm not overly familiar with how the T-Flash chips work other than they retain data without power for roughly 100 years and if you send a static shock through them then they're toast with no change of data recovery whatsoever.
I have no clue if they/how to perform forensics on a working chip for "deleted" data recovery.

Re: Solid State Hard Drives
There are lots of reviews on the CustomPC/BitTech site
http://www.bit-tech.net/hardware/storage/
TRIM support definitely seems to be an issue for certain drives.
According to their tests, not all SSDs are made equally either so be careful what you buy!

Re: Solid State Hard Drives
i wonder if power usage increases as capacity does.
And they have specialty controller chips on them that make sure you aren't reading and writing to the same place all the time on the drive, as flash memory has a finite number of read/writes available.

Re: Solid State Hard Drives
Yeah everywhere says they are more reliable and last longer than normal hard drives but then they also say that they can only perform a certain amount of read/writes and then they just die... I guess it depends on just how many reads/writes that is.
Anyway, I think I'll probably get a 64 GB SSD drive as they are not that expensive, then Windows can just boot from that and my applications can run from that so I'll get all the speed benefits... until I come to load something from one of the other hard drives. Ah well, should still be noticably faster
So can anyone confirm if you need anything other than just a normal SATA cable to use these things?
Cheers

Re: Solid State Hard Drives
When I last was researching then there was a mounting/adapter case that allowed them to be installed in desktops as they are originally for laptops. The adapter cases hard issues with the contact pins aligning so I put off purchasing a SSD drive until that was worked out. Hopefully things are better now.

Went for the Corsair 64 GB Performance SSD drive

It should arrive the same day as my Windows 7 disc (if the delivery estimates are accurate anyway) so my PC is going to get a major speed boost that night
I'll post my thoughts on the SSD side of things in this thread when I get it all installed.

Re: Solid State Hard Drives
Wow, $100. Thats cleap but its only cloning the drive. Now if you have drive failure of a physical media type instead of the components that spin the platters then maybe it would be more.
I have 2 drives to recover data from as they both stopped spinning. So that recovery would be to change the platters to a new drive so they spin. Hopefully will be less then 200 ea. Thats $ I could use to get my SSD's

at an 8 hour day, that implies one million writes. Last i heard they were good for 100,000 writes.

Re: Solid State Hard Drives
100,000 writes doesnt seem like much to me though... it seems like too little for them to actually be used as a normal hard drive for your OS to run from etc. Surely they would last less than a year if that is true?

it's the smart controller that saves the day. It randomly writes to different locations so it takes a long time for a single block to be written to that many times, and reading doesn't damage them at all. I only know this about them, and i know something about flash memory. There are different types. Older lower capacity models last longer because to save space some manufacturers are switching to 4-state flash memory which can actually hold 0,1,2,3 instead of 0,1. The problem is this memory wears out faster. The unit linked to above has a 64mb cache! This probably also severely lowers the writes to the drive. Kind of odd they list speed for a "sequential read" considering there's no moving parts.
I've seen sd to ide adapters. I wonder how well they work? a usable-size for an sd card to boot from is in the hundred dollar range.

i watched a thing on System about this. You know how you boot to your desktop and windows is still not really useable for a minute or so while all the background crap is going on? This doesn't happen with ssd drives. Couple this with faster booting and it's a win-win.
