Smile What is your experience with SSD?


Are they reliable for many years? I learned that traditional, older 2.5 inch HDD start to break in a couple of years.

I've had my SSD for at least 4 years (if not closer to 6/7 years) and mine is still working as well as it was, when I bought it. I've only ever had Linux install on it tho.

An SSD drive is basically a bunch of chips instead of a spinning platter (where the data itself is stored). Where as the "traditional" platter HDD has the read and write heads, that read/write the "platter", rather than chips.

This is mine:

My experience with various low end SSDs is that they are nice and reliable. We have a fleet of about 200 kiosk scanners with low end 30GB Toshiba SSDs. In five years of use, only one of those SSDs has gone bad. Be aware that when an SSD goes bad, though, it may not give any sort of warning that it's going and POOF it's completely dead. So, backup any data you care about!

I also have a few other SSDs of various sorts, and none of them have failed on me after 3-5 years of use.

I've also had pretty good luck with low end USB2.0 drives used as normal OS drives (not LiveCD style - normal hard drive style install, so there's frequent writing to it). Some of these are used on machines as primary OS drive on 24/7. So far, only one of them out of about half a dozen has gone bad. The first 5GB of it is still good, though.

In contrast, I've had pretty poor luck with (very old) Compactflash cards and SD Cards. I can't say precisely how much failure I've experienced, but it's enough that I don't ever really trust them. My usage with them is very different from my use of SSDs and USB2.0 drives, though. I've used them as FAT32 drives for digital cameras mainly.

SSDs are rated for terabytes of writes. You can read as much as you want. I have several Samsung 800/850 drives which are rated for 150TB writes. At 4GB/day of writes, which would be excessive, the drive should last for around 100 years.

And SSDs can handle mechanical shock much better than HDDs. Although, in storage, the data is preserved much longer on HDDs than SSDs.

I doubt they will last as long as claimed, many rated for home use 5 years. Enterprise level mechanical drives would last longer/be more reliable.

SSD's are fast!

By the time you need a new drive, you will want a larger faster model anyway so if you are considering a ssd, might be time to get it.

Been using a few SSD for a couple of years now without any mishaps, much faster boot ups with them, & not as unstable as a spinning disk when moving around with the laptop system running.

Been using here for a few years as well. AFter I switched my first laptop over, I had moved all my laptops over to SSD's within a year. In desktops, they're great for performance, but don't really give you any other advantage, but in Laptops, they're usually a little lighter, use less power, AND increase the performance, so they're IMO absolutely essential in laptops anymore.

I have an SSD on my laptop; almost 2 years old with no problems so far. It's a Crucial SSD that I installed myself because the SSD that came with my laptop was way too small for my needs.

In a small office or home study I enjoy the silence.

Hmmm, yeah, I guess if you build fanless/low rpm fanned desktops that might be something. Hadn't ever thought of that. My desktop you certainly can't hear the 2nd drive (platter) over the raging CPU & GPU fans.

Guess I must be lucky as the noise made by the two fans in my desktop case are barely noticeable. You have to stop and listen for them to notice them.
Plug in the HD I use for a backup and all that changes.
