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.

Here is an issue I think deserves to be adressed: could an conventional HDD (with 2-3 or 4 platters) slow down the performance of a PC , even if that PC boots from an excellent SSD drive, like an Intel X-25M? Let's say that on the SSD lies only the operating system, and that onto the conventional HDD lies the movie and music archive. But both drives run at the same time, and it is a well known fact that the PC runs at the speed of the slowest component (in our case the conventional HDD).I did not found ANYWHERE in the Web a review, or even an opinion regarding this issue.
I would appreciate if I get a competent answer.
Thanks a lot!

That's a good question, and I too would like to see a report from someone who has done it.Some of your assertions/assumptions are not quite accurate. A PC doesn't "run at the speed of the slowest component", but rather it's performance is limited by the slowest component. Depending upon your usage patterns, a slow component may have very little effect on performance or it may make the machine nearly unusable. I think that's probably what you meant, I'm just clarifying it.
As for putting the OS on an SSD and user files on a HD, you would want to have not only the OS, but also your applications (at least your frequently used ones) installed on the SSD. Put user data (especially large files such as .jpg, music, video, etc.), and less frequently used applications and data on the HD. Typical user documents (.doc, .xls, .pdf) can be on either drive, but access might be better with them on the SSD so that you don't have to wait for the HD to spin-up. In that case, the HD might stay spun-down (low power idle) most of the time, which might improve battery life a bit.
Databases are a bit trickier. It depends upon how large the database is, how much space you have available on the SSD, how complex the data relations are, how complex the queries are, how important performance is, how much RAM is available, how well indexes are used, and how well the database program can take advantage of caching. Performance should be as good or better with the database on the SSD, but the difference may be so small that it's not noticeable, or it might be dramatically faster. That one is basically "try it and see".
Where to put the paging file/swap space? That's a tough one to answer. Putting it on the SSD might be slightly faster if your SSD has high write speeds, however,that will increase the amount of writing the the SSD and could potentially shorten it's usable life. It also seems like a waste to use expensive SSD storage for swap space. You should be able to minimize those by using a permanent swap space of the smallest practical size for your environment.
However, putting the swap space on a less costly HD means the HD will be spun-up (active idle) and/or active more often, possibly costing you some battery life. Also, while the HD may have very good streaming write speeds, it's streaming read speed and random access (read or write) speed will be slower than most SSDs, so you're likely to have slightly slower overall response and slightly shorter battery life than you will by putting the swap space on the SSD.
On a desktop machine with a very fast HD, it might make sense to put the paging file on the HD (or to put a small swap space on the SSD and some more on the HD), but on a machine where battery life is an important consideration, it might be better to have the swap space on the SSD, even though it's "expensive".

just turn the page file off, and get yourself 4 or 8 gigs of RAMgstrickler - Monday, August 31, 2009 - link
Windows doesn't like to operate without a page file.smartins - Tuesday, September 1, 2009 - link
Actually, I've been running without a page file for a while and never had any problems. Windows feels much more responsive. You do have to have plenty or ram, I have 6GB on this machine.mtoma - Thursday, September 3, 2009 - link
In my case, it's not a problem of RAM (I have 12 GB RAM and a Core i7 920),it's a problem of throwing or not 300 dolars down the window (on a Intel SSD drive). Currently I have a 1.5 TB Seagate Barracuda 11th generation, on wich I store ONLY movies, music and photos. My primary drive (OS plus programms) is a 300 GB Velociraptor.Do you think diffrent types of Windows behave difrent if you remove the page file? It seems to me if I remove this page file, I walk onto a minefield, and I don't want to do that.
Besides that, my real problem is to use (when I purachase the Intel drive) the Seagate Barracuda in a external HDD enclosure OR internally, and thus, possibly slow down my PC.

Adding a slow hard drive to your system will not slow your system down (well, apart from a slight delay at POST when it detects the drive). The only difference in speed will be that when you access something on the HDD instead of the SSD, it will be slower than if you were accessing it on the SSD. You won't notice any difference until you access data from the HDD, and if it's only music, movies and photos, and you're not doing complex editing of those files, then a regular HDD will be fast enough to view and play those files without issues.If you don't plan to remove it from your system, then attach it internally. Introducing a USB connection between the HDD and your system will only slow things down compared to using SATA.
Removing the pagefile can cause problems in certain situations and with certain programs (Photoshop, for example). If you have enough RAM, then you shouldn't be hitting the pagefile much anyway, so where it's stored won't make so much of a difference. Personally, I'd put it on the SSD, so that when you do need it, it's fast.

Won't Windows write to the page file regardless of how much RAM you have? I was under the impression Windows will swap out memory that it determines isn't being used / needed at the moment.If you absolutely need to have a page file, I would use available RAM to create a RAM disk, and place your page file on this virtual disk. That way you're setting aside RAM you know you don't need for the page file, since Windows will write to that file anyway.
If you can, just turn it off.

Would someone please have the courtesy to test those things in a business environment? I'm talking about servers. Database, webapplication, Java, etc. Reliability? Maybe even enrich the article with a PCI-E SSD (Fusion-IO)?ciukacz - Monday, August 31, 2009 - link
