How reliable are SSD drivers if do a lot of software development (incl. database) and test in virtual OSes on Parallels?

I've read stories that oh heavy writes it last 1-2 years.

Many SSD's have been having higher failure rates than HDD's and on top of that, you generally cant tell when it is going to fail because it offers no signs, no clicking or anything else, they are simply working normally one second then not working the next.

With a HDD, that does not happen often unless a surge or something else causes the controller board to die

but generally when a hard drive is failing, you will notice mechanical issues such as additional noise, poor read access times, issues spinning up, higher error rates on the error correction.

On both HDD's and SSD's the SMART rarely ever kicks in.

With SSD's since there is a known range of write cycles each chip can handle, the drive can keep track of it and after a certain point, switch to a read only mode allowing you to backup your data. You can test this by running spinrite or some other write intensive program on an SSD, you wil kill it fast, since most SSD's tend to fail after around 40-50TB of data has been written to them.

Currently SSD's are not at a reliability level where they can be trusted for very important data. Especially the MLC ones, the SLC drives can handle more data written to them but they are insanely overpriced.

Most of the reliability reports due to wearing out of the drive are based on the work load of a very basic user, and not the user likely to buy an SSD.

Many SSD companies tend to claim that their drives may last about 5 years

But for heavier users, eg ones who may use it for workstation related tasks where they may have their video editor and cache on a SSD in order to speed up that process, they may be pushing upwards of 300GB+ per project, especially if they edit 1080p+ content

they will be lucky if their MLC lasts more than a few months.

If you are going for an SSD, make sure it only contains the OS and data you can easily replace, everything else goes onto a standard hard drive, with an additional backup to another hard drive where you will update regularly.

For most people where their SSD's may fail before the write cycles are exhausted, they will encounter a issue of the drive simply failing instantly and their data will be gone

Every SSD is more reliable than an HDD because you can actually determine exactly when it's going to fail. Nowadays modern SSDs are adapted for heavy use and lasts a lot longer. Normal geeky use is about 40-50 years until wearout. Don't know how much you're writing to it.

Since you're into software development, it is needed that your drives are capable of running resource intensive applications. A friend of mine is a geek and is using Strontium's solid state drive which delivers a substantial performance boost over conventional mechanical hard drives. It gives ultimate storage solution, preferred for the high performance, low power consumption, reliability and small form factor. If you are planning to opt for one then go for it...

Well, most people on a budget use SSDs to store their operating systems and maybe some programs that take a while to load on a conventional hard drive. Everything else goes on an actual hard drive, for the sake of that price per GB efficiency as we usually don't care about the speed of the drives we store data in.

there is a limited number of writes but even constantly adding a deleting large files it'll take you a looooong time to reach that maximum. especially in like a 512 GB drive. it'll outlast the computer its in for sure. they're way more reliable too. you don't have to worry about a head crash destroying your drive. they can become corrupt though, but still i would say more reliable than a HDD. plus much much faster. you'll never have to defray. no seek time = extremely fast.

SSD are only good if your not going to be wrting to them that much, the more you write data to them the quicker they wear out.

if your going to be doing a lot of data writing, then go with a HDD.
