    What is the price of the RAID controller? It seems like in this setup, you’re only including the cost of the SSDs themselves; and there isn’t any discussion of the RAID controller.

    Most desktops and home computers do not come with a built-in RAID controller. In that case, you would have to use software RAID. Software RAID is substantially slower than hardware RAID, enough so on some systems to abate a noticeable portion of the performance benefit of SSD. It’s also strewn with OS-specific caveats.

    Also, Software RAID controllers on many operating systems are not aware of TRIM. TRIM is what makes the data distributed across the NAND Flash SSD, so that one block does not get over written constantly. If you have a hardware raid controller that is not TRIM-aware, or, a software RAID setup that is not TRIM-capable; you will drive your SSD into the ground within a year or two of normal use. Your corruption will be duplicated to both drives. Excellent!

    Many machines have RAID controllers, or support software RAID already. Apple’s OS X for example supports RAID-0 via software, and the performance benefit is significant enough to benefit users without a hardware RAID controller.

    You may disagree, but we’ve been doing it for years, and our experience makes it a sound recommendation in our opinion.

    Software RAID also passes through TRIM commands, though the Sandforce controller in the Intel 330 does a good job of garbage collection, even when TRIM commands are not passed.

    The assertion that not using TRIM will “drive your SSD into the ground” is not correct. Vendors like OWC actually encourage users to disable TRIM on platforms like Mac, and have not encountered the widespread failures you are stating.

    Most consumers machines do not have hardware RAID controllers. It’s about $200-$500 extra for a standard RAID controller. Only high-end laptops such as the ThinkPad W series contain these, and most desktops omit it. For example, Dell charges $200-$500 for a PERC Controller.

    OCZ is an exception on the TRIM support since their internal controllers handle the garbage collection with the understanding that . Intel does this as well a tthe controller level, but in my experience, it is not a best practice to leave TRIM off if you have TRIM support when using Intel SSDs.

    I’ve sent back about a half a dozen intel SSDs between 2010-2012 that were used with XP or Mac systems without TRIM that needed to be returned under warranty since they crashed and were inaccessible and unmountable in other systems (we had backups..). I’ve also seen performance degrade orders of magnitude — from 35,000 iOPS to around 7,500 iOPS; as a result of usage of an intel 320 series SSD with a database like MS-SQL, constantly updated, with no TRIM support.

    One great thing about software RAID 0 — loose one SSD, you loose the whole array, unrecoverably so.

    I’m sure you have had anecdotal experience where you haven’t had issues. But, among myself and colleagues who work in Enterprise IT, this is certainly seen as being a hack of sorts and not a ‘best practice.’

    It would strengthen your article greatly to give your readers more information on RAID support with SSDs, as you’ve done in reply to my comments, and include some of the caveats there. At the very least, it would be a best practice to point out that users should be backing up their data if going with such a setup.
