Hi All,
Im trying to find out if it is a good or bad idea to get a SSD for my wife's computer. She manages her own web store so everyday see adds new products which means, downloading thousands of new/updated products from her suppliers web portal, editing them in excel then uploading to her site, She also does the same for images for each product. She usually downloads/edits/uploads/deletes aprox 30 gig's a day.
I dont know if that will kill the SSD in a very short time or not. She is currently using a old WD 640gig black edition 3gig/sec hard drive. I'm wanting to get her something faster but very reliable.
I have a Samsung 830 250 gig SSD in my gaming rig and love it, I would probably get her the same or maybe the 840 pro series.

I would appreciate it if you guys could steer me in the right direction. If the HD crapped out, that would be a very bad thing.

Thanks
Ken

A snappy 830, 840 or 840 Pro ssd won't hurt but the speed gains of an ssd reside in executables and with high read/writes. It appears the bottleneck will always be her network connection speed since the work case here is downloading, manual editing, then uploading. Is she hardwired on gigabit or connected via wifi? If the latter, wire her instead and hopefully you're on cable broadband service and are sporting a router that you can crank up the juice on. Here's how! But before you begin, run Speedtest to find your existing baseline and then your optimized result. You can always buy more bandwidth from your ISP too.

I'm going to try to approximate the useful life of the SSD on a naive approach. MLC flash has an average lifespan of about 10,000 P/E cycles. So for a 256GB drive, you can theoretically write about 2.56PB over its life. Average 30GB a day and you're looking at over 233 years of usable life. However, this assumes that the drive is always constantly shifting in data, which of course, is never the case.

If you choose a TLC based flash, which about 2500P/E cycles, this brings you down to 640TB, or about 53 years. Again assuming data is constantly shifted around.

So in all honesty, I don't think you have to worry. Even if you had 30GB of actual usable memory (the rest spent on data that is more or less permanent), you're looking at 6 years before 30GB poops out with TLC based flash.

She is wired and we are on DSL not cable :( its not available here.
The upload/download speed for her work is fine, were getting about 14gig DL.
she uses Microsoft excel, Bimp, Photoscape, Quick books misc. I wanting the programs to open and work faster and a SSD would fit the bill, I just wasn't sure if it would poop the bed in a year.
Thanks for the longevity figures ;)

Sounds about right!

@ OP, you'll upgrade your SSD for speed and/or size before EOL will ever be a remote risk factor.

No problem. But again, I have no effin' clue how accurate that really is.

14Mb/s is excellent for DSL. But what about your upload? That is where I bet her work just crawls. Broadband should 50% of download, DSL is often 10-15%.

I'm in no way anti-SSD, but it's not going to help speed up her office app work and that's all she's doing based on the programs you just shared. You gotta speed up the human interface, or run batch scripts and auto templates for the editing that she is doing. A not too crazy option may be to offshore her work, if it's truly a daily frequency. You might be shocked at the cheapo rates in AsiaPac for such busy work. Which would in turn free her up for other tasks and business needs.

All said, still get her an 840 Pro (128= $120, 256=$200) for Valentine's Day...why not show her just how much she means to you.

We only get around 1mb/sec upload
Great idea for a Valentines day gift, the SSD will last a lot longer then roses lol
