SSD Thread (Benchmarks, Brands, News, and Advice)

Well I couldn't get the set password to work in Ubuntu for the security erase because I was getting:
Issuing SECURITY_SET_PASS command, password="Eins", user=master, mode=high
SECURITY_SET_PASS: Input/output error

I went ahead and executed the command for the security erase anyway, and it seemed to have done the trick. Brought up the whole 37GB in disk management, and I was able to initializie it.

 

Can you recover accidentally deleted files from an ssd like on a hdd, or does trim permanently erase them?

 

You should be able to until TRIM gets them. So you'll have a small window of time after deletion

 

I would think that even after TRIM it's possible to recover files if you have the right tools. But I haven't tried it.

 

Hi guys! I'll try to be short..

Finally I've setup the SSD I bought a while ago (OCZ Agility 2 120 GB), installed Windows 7 Professional 32bit and did (hopefully) all of the optimization for the SSD (no indexing, max performance etcetc)
Created a Ramdisk of 750 MB (though I realized later that my laptop has 3GB, thought it was having 4). I redirected here the TEMP and TMP folder and set the only paging file (200MB) here too.
Then I decided to switch browser (always used FF), since in my not-so-new laptop of my father, Chrome was running so fast!
Installed it and directed the cache on the Ramdisk.
Chrome is really slow in loading pages, worse than me using FF earlier on the same connection ofc. But every once in a while has its glory moment and loads fast a couple of pages.
So, disappointed, I decided to go back to FF and setup everything to be everytime copied between Ramdisk and SSD.
Needless to say, even FF sucks.
Then I opened the default profile in FF (hence physically stored on the SSD) and - whoa!
really fast and good!

so, what am I missing? shouldn't be RAM even faster then SSD? why is FF (and supposedly even Chrome) lagging cos it is 'stored' on the RAM disk?

The reason why I redirected those stuff to RAM disk is not to have even more speed than SSD (than allegedly doesnt come) but to try to 'preserve' the SSD a bit from all the writing cycle that browsers do.

Thanks for anyone who can give me a hint!

 

Hello,

As much as I would like to help, your scenario appears pretty unclear to me...

Is what you so call a RAMDISK a part of the disk (HDD or SSD) that you instruct your system to use as RAM ?

RAM is ALWAYS faster than ANY SSD, indeed...

Do you REALLY need a pagefile ?

Ever tried to just use your SSD as an SSD and see what it's worth ?


I humbly think that if you provide us with ALL your system's specs, it'll be easier to help you out...

Cheers !

Actually I lied, the TRIM command is sent immediately after the delete command, so when you delete something from a TRIM-enabled SSD on a TRIM-enabled OS, your file is gone forever.

The "right tools" in this case probably don't exist, and if they did, they would be very expensive hardware, not software. But in my limited forensics experience, there are no tools capable of retrieving data overwritten or TRIM'd on an SSD (which is actually the same thing).

 

nope, RAMdisk is a part of the RAM that I instruct the system to use as a disk so I can tell the system to redirect there files that are continuously being written and hence the OS will do that on the RAM (preventing wear, that is my main aim) and not on the SSD. (said that, this should let the PC reacts faster, as it is loading on RAM, but being faster is not my main concern; else being slower it pisses me off a bit..)

that's is what I knew that RAM is faster than a SSD, but still I cant understand why the Firefox profile loaded from RAM is slower than the profile loaded from the SSD.

I don't know whether I really need a pagefile thus I set it up to the minimum.

I'm using the SSD as an SSD, I just want to prevent excessive wear.

well, my sys specs are the following: (maybe I should put them in signature though)
Samsung Q320
Win7 Professional 32bit
3GB DDR2 RAM
SSD OCZ Agility 2 120 GB
Intel Pentium Dual Core t3400
VGA nVidia G105M but I doubt it is really necessary!

thank you for your help!

 

Wait, you put the page file on a RAMdisk? That seems a little counter productive to me.

Also, putting temp into a ramdisk will one day make you sad. You'll be extracting a large .rar or something and you'll get an error saying something about running out of space on your HDD.

 

yes, actually it is a bit.
as I wrote in my first post, i was convinced to have 4GB ram, and that wouldn't be counterproductive, as you can use the half gig that is not being used by the OS.
Still I may disable it but I dont think this is the reason explaining this behaviour!

==

not much as changed, really still slow

 

I have question:
Can I use Acronis Disk Image 2010 to copy (disc C which has 3 paritions (OS, Recovery and Tools)?
After I do that will the recovery option and everything else work on my new SSD?

 

Been absent from the SSD scene for a while. If you all could give me a few updates it would be great. Looking to get the new Intel 300-600GB SSDs. Any news on when they're coming or for how much?

Also is Intel still the best?

 

Intel G3 is expected in feb 2011. There are several faster SSDs than Intel at the moment. Sandforce SSDs are particularly fast during medium heavy multi tasking.

 

OK...

You pagefile is a part of your disk that is used by windows to "prolong" your RAM, so windows use it like if it was more RAM. Therefore, the only reason I can see your computer would behave the way you describe would be that...

What you instruct your system to do on your Ramdisk is actually done on your Disk because windows switches your Ramdisk's stuff to the pagefile because you do not have "too much" RAM; see the paradox here...

Thus, it's actually taking longer to proceed because stuff has to be writtten in RAM, then on the pagefile, and maybe then back to RAM, so this would explain that...

It's only my point of view, but doing the following should clear that point:

Just get TOTALLY rid of the pagefile, and see if it's faster; ifyes;goto:you-solved-your-problem.com; ifno;goto:we'll-go-from-there.org

Make sense ?

PS: My advice to you is to use your SSD as an SSD, which means to stop worrying about wear and stuff; your SSD is made to endure such writes (random and lottsa 4Ks); just make sure you backup your data on a regular basis, and you should be enjoying your SSD without having to babysit it !

 

Some good SSD bargains:
OCZ Agility 2 90GB Sandforce SSD for $140 AR
Patriot Inferno 60GB $129 AR
Intel X25-M 80GB $169.99 After $30 MIR
http://forums.storagereview.com/index.php/forum/14-storage-and-tech-bargains/

 

Well it looks like I spoke too soon. The Intel X25-V SSD is giving me the same I/O error and failure imminent message. I called Intel and they are going to RMA it. So thats good.

 

Agility 2 90GB is 3.5" (just a note).

And what's that with 90 GB capacity?

 

So i was thinking of buying an ssd.. Is the INTEL X25-M 160GB SSD GEN 2one that you can recommend. And is 340 bucks a fair price for this??

 

I'd guess it works well in competition against Intel X-25v 80GB.

 

REGARDING RECOVERY OF INFORMATION WIPED BY TRIM....

I did some checking with an industry expert who is very close to RAISE technology and he stated as such:


"If the OS sends the TRIM down to the drive, each drive may process the information differently, but in general it will mark that data “invalid” so it would be very unlikely you could get that data back since the SSD would have already “unmapped” it."

Hope this helps...

 

If it is marked as "invalid" it sounds like the data is still there...

 

Once I managed to recover around 80% from 2 GB of pictures after three days of light usage, but I have TRIM turned off so only GC working.

 

And i think there's also a difference between what we can get back as to what the FBI can get back, for example.

 

Types of deleted files:


Deleted: Can be easily recovered from Recycle Bin.

Shift + Deleted: Can be recovered somewhat easily by commercial programs [Undelete - Restorer Pro - Etc.].

Deleted AND Multiple Overwritten: MIGHT be recovered ( NOT easily) by special high-end products (electronic microscope and other pretty expensive stuff).

Intel's 3rd Generation X25-M SSD Specs Revealed - AnandTech :: Your Source for Hardware Analysis and News

 

Dammit: no word about ATA/ATAPI- 8 compliancy..

TO ALL SSD's MANUFACTURERS: WE WANT TO TRIM IN RAID, PLEASE !!!​

and THANKS in advance !​

eYe​

​

 

if intel sells it < $1.5 per GB, I think we will start seeing ssd's going mainstream. 300GB drive around $400 would be awesome.

 

YAY! Thanks.

Interesting tidbit here from the article:

Standard MLC will last for 12 months after all erase/program cycles have been consumed.

Is this true for all SSD's? They do state enterprise drives last only 3 months. Sounds like these things actually degrade once no longer able to be written to, that's odd.

And yeah, if I can get a 300GB for < $400 I'm sold.

I'll be buying a new laptop next spring most likely and should be a good time to buy at least technologically speaking. New/cheaper/faster SSD's, Sandy Bridge, EFI BIOS, USB 3, SATA 3 (hopefully).

 

"The SATA implementation has been updated to support ATA8-ACS so it’s possible we may see official 6Gbps support once Intel has a chipset with native support."

 

Yup, read that...

This is SATA-3 implementation in the ATA arsenal...

But my concern is more to TRIM in RAID than SATA-3 implementation, as I can't (as of now) benefit from it, my system being SATA-2, and nowhere did I see anything about ATAPI- 8→TRIMin RAID in what I read...

Because the ATAPI-8 compliancy I am (we're all) waiting for is for the SSDs themselves to become such ATAPI-8 compliant, which is the only obstacle for us to TRIMin RAID...

sad as that can be...

 

I hope it's a simple mistake!

Code:

   	                              X25-M G2 (34nm)  	 X25-M G3 (25nm)
Max Power Consumption Active/Idle  	 3.0/0.06W     	 6.0/0.075W

 

ya, saw that too, but wasn't surprised, don't know why...

 

Still going to wait until Gen 5, but Gen 3 sounds hot.

 

gen 5? lollll damn i wish i had your patience

 

Gen 5 should be out at the same time as Intel's 22nm Haswell cpu's, meaning 2013 is when I upgrade to a new laptop and new ssd.

 

Wow, that's a long time away, start saving up yet? ;P

A dollar a day.... a dollar a day. if you walked around a city looking at the ground for loose change when you go out you'd find more than enough to buy a laptop by then

 

The way ssds work is that you can only change entire blocks to 1s, but you can change pages to 0. Thus if you want to write over a used page, you have to reset the block to 1s then rewrite the old data and write new dara. Trim does this on deletion rather than on writing, and in the background. Using trim literally securely deletes everything you delete. And unlike a magnetic drive, there is no faint magnetic signatures to find that have been left behind.

 

So does this mean that no Recovery Software will ever work on a trim enabled drive? WOW! Gonna think twice about emptying that recycle bin

Nope, SSDs are very different from HDDs.

 

I think I landed somewhat to you-solved-your-problem.com thanx!
but indeed im having other problems not-SSD related in win7, so I might switch definitely to Ubuntu.

PS: actualy Im treating my SSD as such, hence a very delicate a new piece of technology!
btw, what is the point of backuping data? wasn't it that when a SSD is worn you just can't write anymore, but you will still able to read???

 

Hi guys,

I find it interested to read most of the thread regarding to solid state drive benchmarks.

In fact, I've just bought my Asus G73-JW with 128GB Crucial C300 SSD and 500GB 7200rpm in RAID0..As far as i know chipset HM55 is hooked up in that lappy.. However, I'm getting annoyed of SSD durability which is recited in here recently for not giving a high-end performane for 4k!!.. could someone inform me if this stumbling block has been fixed by Intel's hardware or not.. i really do appreciate it.

Hope there is a good news from Intel according to HM55 stability.

P.S: as soon as I recieve my device, i will post my metrics up in here

catch you later

 

Happy to hear you found the land of problem-solved, MY pleasure

Since you do not describe the other problems, I have to inform you I can't help on those

Since I know nothing about Ubuntu, I just wish you the best with this guy

You are right, and the point of backing up you data is simply to make sure you still have them if your lappy get stolen, or immerged in water, or...


Cheers !

eYe

 

Please see here with regards to Intel Chipsets and SSDs.

Also, when this gets finally resolved, don't forget to thank this guy for all his work !

Patriot Inferno 120GB SandForce-Based SSD - HotHardware

For a time, Intel’s X25 series of solid state drives stood head and shoulders above the rest of the SSD pack. But with the influx of new players along with the rapid pace of innovation in the SSD space, Intel’s aging offerings—while still very good—are no longer a cut above. In fact, in enthusiast circles, it’s drives based on upstart SandForce’s controllers that currently garner the lion’s share of interest. And you don’t have to take our word for it. Just take a look at SandForce’s current list of partners; it reads like a list of” who’s who” in the memory market with names like OCZ, Corsair, Mushkin, G.SKILL, and Patriot, among others.

It’s a Patriot drive that we have on tap for you today. Patriot has employed SSD controllers from a number of manufactures including JMicron and Indilinx in a few of their product lines, but in the newest Inferno series of SSDs, Patriot went with SandForce’s SF-1200 series controller. The specifications for the Patriot Inferno 120GB drive we’ll be testing here are listed in the table below. If you’re familiar with other enthusiast-class SandForce based offerings, many of the features and specifications should come as no surprise. Check them out below and then read-on for the full scoop.

While ssds are rugged and have a long mtbf, you could always get manufacturing defects, get hit wth malware, or any number of situations in which a backup is good. But since most people dont store data on ssds, it might not be a problem.

 

I thought an Asus g73 jw can't support raid 0

 

You also can't put unidentical drives into RAID 0 but you don't see that stopping him...
