USB 3.0 flash drive vs. SSD?

post #1 of 8
Thread Starter 
I found a Patriot Supersonic 64GB USB 3.0 on sale for $115 (today only) and I'm really thinking of grabbing it for my future laptop as my main boot drive. The specs seem to be up there compared to most SSDs in its price. The good thing is that I can easily use it with my desktop as well if I ever want to. I'll be running a light Gentoo setup with dwm.

Is there any real downside to it? Is it worth the cash? confused.gif

Thanks!

I would go with ssd as the write and reads are going to be high on that flash usb. Ssd is going to be made specifically to handle a OS on it.

Prices of ssd these last tow days you could probably pick up a 120gb ssd for the same price.

You can get a 60GB Vertex+ for $60 before rebate, and it has a faster read and write speed than that flash drive.

Most SSD's are capable of 3 to 4 times the read speeds (I'm assuming the listed speeds on that flash drive are sequential, of course). For example, the Crucial m4 64GB is capable of over 400MB/sec sequential. The specs I found for that flash drive on Newegg list it as 100MB/sec, based on their (Patriot's) internal testing. I doubt you'll see that speed very often in the real world.

If you want a portable, bootable device that will work on a range of computers, then do it. But don't expect it to have the performance of an SSD; it will probably be on the level of a mechanical hard drive.

See my last post for specs.

Ehhh, so I guess I should stay away? frown.gif The cheapest I could find was a first gen OCZ Agility 60GB for $100 though.

Go with an SSD. Flash drives have much fewer read/write cycles than SSDs, so it is much more likely that your drive will fail much sooner than if you got an SSD. Plus, SSDs have much higher random read/write, which will really make a noticeable difference in OS performance.

You're not looking in the right places then. tongue.gif

NCIX has great deals on SSD every single week. Add those to cart, and check NCIX out again tomorrow evening. Their new sales usually start around 6:30-8:30 PST, so if you're up around 11PM your time, you can check and see what they've got.

I love NCIX in part because their shopping cart locks in prices, so if the next sale is better or worse you can pick and choose what you pay. I use that to my advantage a lot - gathering the best prices from 2 or 3 weeks of sales, then checking out. (usually on a free shipping promo)

The two SSDs I linked are by no means the fastest ones out there - but they should beat the flashdrive you linked in performance and reliability.

Edit: Crucial M4 64GB for $111.00 smile.gif (one of the fastest SSDs out there)
