    Be happy to provide that as soon as we have reached 5+ year in the wild life spans of a sufficient sample size of SSDs. In the meantime, you can take Intel, Samsung, and Seagate's documentation including the idea that specific engineering measures had to be taken, including such technologies as wear balancing, over subscription of cells to meet loing term storage minimums, and changes to SMART as admission of lifespan restrictions of the technology.

    If the drives did not have cell failure issues, why did we need this technology?

    Something else to considder: individual megnetic bits in HDDs fail all the time. These do not cause block failure or data loss due to parity used at the block level. in an SSD, when a block fails, we loose the whole block. There is no such thing as bit failure. So, as they admit block failure is not only common, but they've actually designed in EXPECTING it, what happens to the data in the block when we loose it???

    Block failure in spinning disks is uslaly considdered critical if more than 5 blocks fail in the lifetime of the drive, and a smart alert is issued on each failure. SSDs expect to loose as much as 0.1% of their blocks over that timeframe, which is why additional blocks are built in as a reserve.

    Long term, yes, SSDs may prove to have longer total shelf life, but that is NOT the same as data resiliancy and usable reliability. If we loose a critical block in the OS sectors, boot sector, or application code, you get to re-install from backup. Sin ce that's about 50 times more likely to happen in an SSD than a spinning disk, I'm not putting my money on that technology for any critical application unless I'm also data mirroring. (and I have a LOT of critical apps running on laptops).

Over 10-15 years, 10-20% of the light getting to the panel also won't be. If you don't believe me, look at the headlight covers on a 10 year old car...

    You also have to account for battery/capacitor degredation (they need to be replaced every 10 years or so). Also the AC inverter only has a general 10-15 year lifespan. These are maintenance costs that the solar company usually won;t disclose except in fine print, and they're not warantied.

    Then there's the insurance costs. Sure, you might only PAY $36K for solar panels, but they cost $80K. (subsidies and discounts apply, but do NOT count towards repair/replacement). Therefor, your insurance company sees this as a $80K valuation improvement. For a $300K home, that's a 25% increase in home value, and one that's highly suceptible to storm damage, so the insurance hike will either be 30-40% anually, or the coverage will be pathetic.

    The concerns are not "baseless" and in fact, there's substantial data to validate.

    The return rate on defective SSDs for Dell was reported at nearly an order of magnitude more than HDDs (12% vs less than 2%) in late 2008. Newer SSD models offer "wear balancing" (it;s NOT clearly documented which do and don't, so one must be very cautions). A single cell is good for about 50,000-100,000 write cycles. This shoudl NOT be confused with writes for a typcial HDD however as an SSD cell my be written to multiple times due to block sizing difference vs HDD platters. Write amplification further exacerbates this issue. Wear balancing basically referes to writing to random parts of the disk, continually changing the locations data is used in to balance load across the entire availabel cell count as opposed to HDDs which write continually to the same locations repeatedly.

    Many will say that "wear optimized" SSDs can have 3X the longevity of traditional drives. Well, in terms of "spin life" that may be true, but if we're accounting for the fact that MOST people who buy SSDs will be doing so for performance, and that these users experience dramatically higher IO loads than normal users, even with wear pattern analysys the drive will not typically not outlast a typical mid-range drive. In enterprise, especially where high performance data is in use, SSDs are practically doomed to premature failure vs enterprise class traditional drives.

    Further, SSDs have far narrower environmental ranges, and are suceptible to heat and rapid temperature changes in ways that HDDs are not. They're also susceptible to data loss due to unexpected power failure to a higher degree than platter drives. They're also DESIGNED to expect block failure over time, and changes to SMART were necessary so that SSDs don;t report themselves as failed to SMART controllers where a HDD with that many bad blocks would be considdered failed. In fact, to account for this, numerous additional "unusable" blocks are included in the base size of an SDD such that capacity is guaranteed to meet a minimum level accounting for those bad blocks. If that bad block contains critical data, it's gone... HDDs generate far fewer bad blocks under normal use (many generate few or zero over their operational life).

    Fact is, it's not a simple question of reliability, but the fact that manufacturers are deveoping and advertising NEW DESIGNS and NEW TECHNOLOGY to COUNTER the admited questionable long term availability of the flash drives. some of these design changes are also causing backwards compatability issues with SATA (many of the newest SSDs "require" SATA II due to how the drive's internal systems can backfill a queue that doesn't employ NCQ). Other technologies, like hybridizing the drives using larger cache's that appear as part of the normal disk, have been dropped from Windows OS development for Windows 7, meaning drives that do have that capability won't be able to use it on Windows 7 or on some older SATA systems they may "function" on but don;t have 100% compatabiltiy with. The drive may have great reliability, but only if you run on a pre-SATA III bus using Linux and custom drivers... What good is that?
