The SSD Relapse: Understanding and Choosing the Best SSD

All Indilinx Drives Are Built Alike
G.Skill, OCZ, Super Talent and Patriot all sent their Indilinx MLC drives in for review. If you take the drives apart you see that most are the very same on the inside, despite differences externally:
From Left to Right: OCZ Vertex Turbo, OCZ Agility, Patriot Torqx, G.Skill Falcon and Super Talent UltraDrive GX. Only the Super Talent drive uses a different PCB design.
Even the packaging doesn’t appear to vary much between manufacturers; that part I don’t really understand. All that seems to change is the artwork on the outside.
There are some minor differences between drives. Patriot ships its Torqx with a 2.5” to 3.5” drive bay adapter, a nice addition. The Torqx also comes with a 10 year warranty, the longest of any Indilinx based manufacturer. OCZ is next with a 3 year warranty, followed by Super Talent and G.Skill at 2 years.
Indilinx is still a very small company so it relies on its customers to help with validation, testing and even provide feedback for firmware development. As far as I can tell, every single Indilinx customer gets the same firmware revisions. Some vendors choose to rename the firmware revisions, while others do not. OCZ calls its latest stable firmware 1.30, while G.Skill, Super Talent and Patriot call it 1571.
The Indilinx Barefoot controller (right), powered by an ARM core.
Of all the Indilinxites, OCZ and Super Talent work closest with the controller manufacturer. In exchange for their help in manufacturing and validation, OCZ and Super Talent also get access to the latest firmwares earlier than the rest of the manufacturers. Ultimately all manufacturers will get access to the same firmware, it just takes longer if you’re not OCZ or Super Talent.
You no longer need to use a jumper to upgrade your firmware, provided that you’re already running fw revision 1275 or later. If you have a previous version you’re pretty much out of luck as you need to upgrade to 1275 first before upgrading to anything else, and none of the manufacturers make it easy to do. Some don’t even offer links to the necessary firmware you’d need to jump to 1275. Thankfully pretty much anything you buy today should come nearly up to date, so this mostly impacts the original customers of the drive.
Performance, as you’d expect, is the same regardless of manufacturer:
There's normal variance between drives depending on the flash/controller, that's why the OCZ Vertex is slower than the Patriot Torqx here but faster than the Super Talent UltraDrive GX. The manufacturer and size of the flash has more to do with determining performance. Samsung is used on all of these drives but the larger the drive, the better the performance. The 256GB model here will always be faster than a 128GB drive, which will always be faster than a 64GB, etc...
All of the drives here use the same firmware (1571) except for one of the Super Talent drives. That drive is using the beta 1711 firmware with TRIM support that was pulled.
When it comes to the best overall package, I’d say Patriot’s Torqx is the nicest for a desktop customer. You get a 3.5” adapter bracket and a 10 year warranty (although it’s difficult to predict what Patriot’s replacement strategy will be in 10 years).
The Patriot Torqx bundle, complete with a 2.5" to 3.5" adapter.
Prices vary a bit between manufacturers, although most of the more expensive drives here have a $30 rebate to bring their prices in line:
| Price for 128GB | |
| Corsair Extreme Series | $384.00 |
| OCZ Agility | $329.00 |
| OCZ Vertex | $369.00 |
| OCZ Vertex Turbo | $439.00 |
| Patriot Torqx | $354.99 |
OCZ does do some unique things that the other manufacturers don’t such as deliver an overclocked drive (Turbo) and a drive with slower flash (Agility). There’s a Mac Edition of the Vertex, unfortunately it’s no different than the regular drive - it just has a different sticker on it and a higher pricetag.

Another great article. You making me drool over these SSD's!I can't wait till Win7 comes to my door so I can finally get an SSD for my laptop.
Hopefully prices will drop some more by then and Trim firmware will be available.

I use them both because they are damn good and explanatory suffixes. It is 2009, soon 2010 I think we can at least get the suffixes correct, if someone doesn't know what they mean, wikipedia has answers.AnnonymousCoward - Saturday, September 5, 2009 - link
As someone who's particular about using SI and being correct, I think it's better to stick to GB for the sake of simplicity and consistency. The tiny inaccuracy is almost always irrelevant, and as long as all storage products advertise in GB, it wouldn't make sense to speak in terms of GiB.Touche - Thursday, September 3, 2009 - link
Both articles emphasize Intel's performance lead, but, looking at real world tests, the difference between it and Vertex is really small. Not hardly enough to justify the price difference. I feel like the articles are giving an impression that Intel is in a league of its own when in fact it's only marginally faster.smjohns - Tuesday, September 8, 2009 - link
This is where I struggle. It is all very well quoting lots of stats about all these drives but what I really want to know is if I went for Intel over the OCZ Vertex (non-turbo) where would I really notice the difference in performance on a laptop?Would it be slower start up / shut down?
Slower application response times?
Speed at opening large zipped files?
Copying / processing large video files?
If the difference is that slim then I guess it is down to just a personal preference....

I've made it a habit of securely deleting files by using "shred" like this: shred -fuvz, and accepting the default number of passes, 25. Looks like this security practice is now out, as the "wear" on the drive would be at least 25x faster, bringing the stated life cycles closer to having an impact on drive longevity. So what's the alternative solution for securely deleting a file? Got to "delete" and forget about security? Or "shred" with a lower number of passes, say 7 or 10, and be sure to purchase a non-Intel drive with the ten year warranty and hope that the company is still in business, and in the hard drive business, should you need warranty service in the outer years...Rasterman - Wednesday, September 16, 2009 - link
watching too much CSI, there is an article somewhere i read by a data repair tech who works in one of the multi-million dollar data recovery labs, basically he said writing over it once is all you should do and even that is overkill 99% of the time. theoretically it is possible to even recover that _sometimes_, but the expense required is so high that unless you are committing a billion dollar fraud or are the secretary to osama bin laden no one will ever try to recover such data. chances are if you are in such circles you can afford a new drive 25x more often. and if you have such information or knowledge wouldn't be far easier and cheaper to simply beat it out of you than trying to recover a deleted drive?iamezza - Friday, September 4, 2009 - link
1 pass should be sufficient for most purposes. Unless you happen to be working on some _extremely_ sensitive/important data.derkurt - Thursday, September 3, 2009 - link
I may be wrong on this, but I'd assume that once TRIM is enabled, a file is securely deleted if it has been deleted on the filesystem level. However, it might depend on the firmware when exactly the drive is going to actually delete the flash blocks which are marked as deletable by TRIM. For performance reasons the drive should do that as soon as possible after a TRIM command, but also preferably at a time when there is not much "action" going on - after all, the whole point of TRIM is to change the time of block erasing flash cells to a point where the drive is idle.

That's on a Linux system btwAs to aligning drives...how about an update to the article on what needs to be done/ensured, if anything, for using the drives with a Linux OS?
