Originally posted by GreyGeek View PostI checked out the Samsong Pro 256GB drive on Amazon. A couple thousand reviews with 3% of those giving it a one star. The firmware update accounted for a lot of the negative reviews, but there was too many who stated it just failed to boot without previous warnings. A lot of the failures which occurred before two years had passed. That's for a $155 drive. A cheaper one won't be better. IMO.
I'm sure most of us realize that most people don't take the time to post comments or reviews if we're satisfied with a product, only if we have trouble. Therefore in my view, bad reviews from retail customers are taken with very large salt grains - and an exponential reduction in weight. IMO, the 87% 5-star on Amazon is much more significant than the 3% 1-star. Interesting comparison: The Western Digital (my preferred HD brand) 750GB "Black" (performance) model 2.5" drive has a review ratio (5-stars to 1-stars) of 82:4 (780 reviews) and the model closest to your current HD, the 320GB "Blue" drive is even worse at 76:5 (1300+ reviews). Therefore, one can logically conclude that if Amazon reviews are a primary decision factor; the SSD is the correct choice. When you factor in the "free" benefits: power savings (better battery life), reduction in heat (better overall component life), and reduction in accidental damage from dropping, the SSD stands out as the best choice.
My anecdotal experience with SSDs vs HDDs: I bought my first SSD (cheapest I could get) about 8 years ago to play around with it. It died in a couple months and was replaced under warranty. The replacement lasted several years of light use. During that time, I had 4 HDD failures at almost exactly 3 years - just past their warranty expiration. These were heavily used and the first one gave off warnings so I pulled the others (they were a set of 4 used for RAID) all off-line and re-purposed them as backup drives. They all died within 4 months of each other (that's what you call quality control - nearly simultaneous death just past warranty dates ).
Since then, I have purchased Adata (2), Samsung (3), and Kingston(1) SSDs and WD(4) HDDs, none of which have failed or had bad sectors. If it means anything, my sister works for a media distribution company that has servers all over the world. They use Samsung SSDs by the tens of thousands and no platter drives.
The point to all this: There's a lot of FUD about SSDs most of which is debunkable. Computers in general are a fast moving target and SSDs are developing at a higher rate than that. The only reason to buy a platter drive is the GB-to-$ ratio. All other factors have diminished in deviation as to be inconsequential.
EDIT: My oldest Samsung SSD is a 840 Pro model: Power_On_Hours = 24262, Uncorrectable_Error_Cnt = 0, Total_LBAs_Written = 21346150209

Another interesting note: Samsung 850 PRO series drives have a 10 year warranty. Most HDs are 3-5 years. That says a lot.

So, do you have to reparation them to eliminate the Windows exe's and security junk so you can use Btrfs? What about "trim" to maintain speed. Available under Linux?"A nation that is afraid to let its people judge the truth and falsehood in an open market is a nation that is afraid of its people.”

Personal preference and completely unnecessary unless you're just into saving all the disk writes you can, but since mine are single-user machines I also set 'noatime' in fstab.we see things not as they are, but as we are.

Mmmmm ... I've already ordered an identical replace drive, which arrives tomorrow. Also, even though my HD is 640GB the Btrfs scrub checked only 58GB, which is what "show" also shows. I may get a 128GB SSD just to experiment with."A nation that is afraid to let its people judge the truth and falsehood in an open market is a nation that is afraid of its people.”

If I may offer one more piece of advice; I've seen significant improvement in a SATA 1 netbook with an SSD; since on a home computer sustained throughput generally isn't a requirement there's no sense in going for a SATA interface your machine doesn't support. F'rinstance, if your machine can only do 1.5 or 3.0 Gbps SATA there's no advantage to spending extra money an SSD that will talk faster than your interface willLast edited by wizard10000; Aug 10, 2016, 09:22 AM.we see things not as they are, but as we are.

IMO, the added value of better firmware and more current mem chips would outweigh the additional $5-30 or so you'll spend. Furthermore, in this case - the SSD has a better than average chance of outlasting a 2010 model laptop.

Since all SATA III drives are backward compatible, you're actually recommending buying an older (in terms of production date) than what's current. Using Samsung and Amazon again: The only available SATA I drive is 120GB at $60, their SATA II drives have been discontinued and are only available used, but the 128GB 850 Pro w/10 year warranty is the most expensive option at $90. You can get the EVO model (5 year warranty) for $65.

My point is that if your SATA port will only do 300MB/s on paper there's no need to spend *extra* money on a drive that'll run twice that fast. So with a SATA 2 controller if you're choosing between two drives, one that'll do 400MB/sec and one that will do 600MB/sec either will do because both of them will talk faster than your interface and there's no reason to make the extra speed a factor in your purchase decision.we see things not as they are, but as we are.

My anecdotal contribution to the discussion:
In late 2010 I built a new desktop system and I wanted an optimum combination of performance and reliability. I consulted with oshunluvr who suggested a PCI bus SSD would be really fast and not use SATA connections, giving me good expansion capability for large hdds. In the succeeding 6 years I have replaced the motherboard, the graphics card, and the pair of 1T hdds that I use as a BTRFS data storage system, but I have kept the rest of the system including the SSD. Here it is at almost 6 years of running pretty much continuously. I did not remember that there have been 187 power failures -- not sure what that's all about, but I really like the uncorrected error count, out of almost 10 million. It's an ext4 filesystem running a Linux OS.

My point is that if your SATA port will only do 300MB/s on paper there's no need to spend *extra* money on a drive that'll run twice that fast. So with a SATA 2 controller if you're choosing between two drives, one that'll do 400MB/sec and one that will do 600MB/sec either will do because both of them will talk faster than your interface and there's no reason to make the extra speed a factor in your purchase decision.
Additionally, my quick Amazon search shows you may benefit from these other factors without actually spending more, thus negating the dollar argument. Two years ago, I might have agreed with you, but the prices of SSDs have fallen faster than (to quote a Kansas old timer) "a stream-lined sewer lid."
I agree with the gist of your comment, but IMO the reality would likely be one would might up with the faster drive anyway because of the other factors. I guess my comparative retort to your point would be: There's no need to buy a slower SSD just because your interface won't do SATA III speeds.
I think we'd both agree that dollar-to-performance is what we're talking about. I just think the "performance" is not interface speed alone, but also longevity, future compatibility, and modern firmware - all of which are often enhanced with a faster speed rated over a slower model - regardless of interface.
I also now think I've flogged this dead horse enough. It appears we are not far apart in opinions, just viewing it from a different angle. So, I will allow you the final word as we close this discussion <bows gracefully>

If I recall, those PCI/SSD boards were rather "spendy" back then. Sounds like you've gotten your money's worth tho...
