SSD Replacement

[ceehoppy1st]

??? The ad copy lists 4K SEQUENTIAL R/W (not random r/w)? what up with that? You need a pretty good cf slot on your camera/pc /reader to use that through put speed (not the one on UX) I have yet to see a "normal" flash memory device that had decent 4k random specs.

More ??? - the samsang ssd spec page shows R/W power useage as .04/.19W, but on the unit it reads .2A at 3.3V = .66W

nice, excellent for a digicam! or a modded ux cf slot

Well I "borrowed" one of the samsung MCCOE64GEMPP-01A slc ssd & benched it. By the numbers it tests near identical to the stock Sony TZ samsung 64 GB (which is also very close to the UX490 48 GB ssd). 64gb_ssd2.txt
Other than the metal shell on the 01A vs bare circuit board on the Sony units, I can't tell any difference. Like the other samsungs it is also UDMA 4, so decent speed, looks be as power efficient, & has similar random R/W as a mtron,too. (such a deal!)

Ok i am NOT PUTTING THE CF CARD IN THE CF READER. It is going into a cf to 1.8" converter

That is pin to pin with no convertion

That is pin to pin with no convertion. Remember both zif and cf are ide based

Thinking of upgrading to one of those Renice K3VLAR SSD's anyone get a chance to see/play with one in person?

[bigs]

there seems to be many models of K3VLAR SSDs. The one that I would consider is the K3VLAR-E as it sports the Eastwho controller which seems to be the one found in Photofast V4. Performance based on web site comparisons seems very similar. And we all know Photofast V4 is a pretty good SSD. Extremely good read speeds with adequate write speeds, the 64Mb SDRAM helps in this department. Most importantly SSD's using the Eastwho controller, seems to have the garbage collection feature, which for me is a life saver for those who don't want the hassle of running a Trim approved operating system like Windows 7.

I tell you now, you do need some sort of trim or garbage collection on SSD, otherwise once the drive has been filled, the write speeds will drop so significantly that it will write slower than a conventional hard drive. This effect is sometimes known as the freeze or stutter effect, most pronounced when using SSD with the J micron controller in it.

Hope this helps

Hi

I've got a lead on one of these. do I require an adapter or can it be connected directly to the the FPC cable in the UX?. I assume that the metal covers on the SSD wound have to be removed to fit in the UX? And is there anything else that is needed to get this SSD to work in the UX?

Cheers

That Samsung ssd is a direct replacement for the stock Toshiba hdd. It connects to the FPC with a zif socket. Leave the shell on & it'll fit in the rubber isolators & frame like the hdd. If your UX has a stock "bare" ssd (UX390 / UX1XN,etc), then you'll want the hdd caddy like this. Win7 is a good choice for the os. If you want to use XP, then be sure to google "partition alignment on ssd" in order to avoid performance problems after setup. Win7 & Vista don't have this problem.
