I haven't tried with exactly the same, however I can tell that I tried with MK1214GAP, MK4032GAX and MK6021GAS (this should be closesed to yours and that's the one I made most testings with) and I didn't notice any problem.

Thanks you for the information.

Werner, have you measured a time of loading from 1G card with HD MK6021GAS ?

In case of external battery; already few online stores offer Nexto CF OTG, but no one offer a battery. Let us know, if you find an info from Korean side please.

Martin
 
Will do. I've already asked the question, I'm waiting for a reply from NextoDI.

Your in Japan Martin? With any luck maybe someone there will have already got a shipment or something, but I asked to know wherever their may be a retailer with them.

About 8 MB/s with the 4200 rpm Toshiba (using a reasonable fast CF card like Sandisk Ultra II) - about the same like with all other hard disks. So transfering a full 1GB card takes about two minutes

There is not so much difference in speed, with the fastest 7200 rpm drive I got about 9 MB/s. Transfer is mainly limited by CPU speed at the Nexto OTG and only slightly affected by hard disk speeds (access time).

My last questions,
I plan to use Nexto CF OTG like back up for PD70X.

Can Nexto be powered by PD70X only, means if Nexto is not recharged, it will work both together and copy data from PD70X to Nexto?

Do you think there is a crucial reason why to coupled Nexto CF Ultra (after it release) with Nexto CF OTG or there is a second, also a good possibilities coupled PD70X + Nexto CF OTG (since I think it would be better have at least one drive powered by common AA batteries.)

Thank you.
 
No... the Nexto-CF OTG can not be powered by the PD70X. The PD70X should not put out any voltage from it's USB, it would act as a client where the Nexto-OTG is the host. The Nexto will have to have some power source.

The Nexto-CF can be fully recharged from four AA alkaline cells. All you need is a four cell battery holder, with wiring going to the appropreate sized jack. Four AA NiMH cells can easly power the Nexto-OTG, but again, you need a four cell holder with the correct jack to fit in the Nexto-OTG...

I'm not sure what voltage the PD70X's AC adapter is... probably more then 6 volts, so it's unlikely you can use it's AC adapter for the Nexto-OTG.

If you really want the ultimate in AA power... You'd probably be better off with a 8 cell pack, build in a DC-DC step down converter, and put out the 5 volts nesssasary to power a Nexto-CF that way.... You'd probably be able to get about 6 hours of operation from 8 AA alkaline cells, maybe 9 hours from 8 Lithium Iron Disulphide cells... but you'd need a bigger hard drive before you'd run out of power.

Curerntly you can't do a data 'snyc' from the PD70X to the Nexto-OTG, you can do this with the Nexto-CF, and will also be able to do it with the 'ultra' product... NextoDI says they will try to implment a 'sync' to generic PSD in a future firmware release, but who knows for sure. You should however be able to copy data between the PD70X and the Nexto-OTG using the current browse and/copy functions of the Nexto-OTG.

The Ultra's real advantage over current products will be proformance. Based on early info, I'd expect it to be around 50% faster then the current NextoDI products, however it's still to early to say for sure. No one outside of NextoDI has actualy had one yet.

Beta testers have been told maybe two months before we would get a beta sample. It's hard to say for sure how much time would be needed for beta testing. Likely close to a month?? I don't know for sure. Given that, I'd say maybe in the 3 months, give or take a month or two. If it's like what happend with the Nexto ND-2300 the Ultra could go on sale in Korea during beta testing. I guess the reasoning for that is, that NextoDI may feel confident in the hardware, but less so in the firmware, and could offer local support to the Korean market and therefore be willing to risk early release in Korea.

Do you have an idea, when they are going to release Nexto Ultra?
Is it like next month or end of the year.

Glenn, I guess there is another reason too: many additional beta testers for free ;-)

Hi Martin,

Just wanted to warn you about that hard drive. I had exactly the same model in my laptop for 2.5 years, and it has failed a week ago. I found many reviews online, that 2 years is exactly the time when you can expect this toshiba to fail. Too bad. Anyway, do not trust your valuable data to single storage place.
 
Thank you for the warning, however I plan to buy one more PSD. I will wait for Nexto Ultra or I will buy HyperDrive-actually, I like to have one drive powered by AA batteries since AA batteries is possible to by everywhere. Also there are no extra batteries for Nexto Ultra.
 
Great information in this thread so far guys!

Question:

Nexto with the internal cell + the external battery stick (the one that goes into the sleeve on the side). How many Gigs can be transferred in normal day to day use? I’m very interested in a real life scenario where you go on vacation and transfer 2-4 GB a day to the Nexto. How many days will it last given the shutdowns and power-ups every day and probably some normal power loss of the pack over time? I’m trying to figure out how many external packs should I buy for a trip where recharging might not be possible.

The Nexto-CF ND-2500 will transfer data for about 45 minutes or more on a single charge of it's internal LiPoly based battery. How much data you can transfer during this time depends on what memory card(s) your copying from. A Sandisk Ultra II card will transfer most common photo files at about 8 ~ 9MB/sec which would mean you could transfer about 22.5G per charge. A slower card will transfer less, faster card more...

My PQI cards transfer at about 4.5M/s, my ATP ProMax 150x transfers at 10.8MB/second...

The original ND-2500 external cell has 1800mAh capacity, which is 3 times the capacity of the ND-2500's internal battery, so you should be able to get an addtional 135minutes of operation with a single external cell of this capacity. Using this cell alone could add another 40-70G of transfer.

Apparently there are newer 2200mAh external packs now available, these should add 165 minutes or so of operation to a ND-2500, so this would add maybe 45-80G of tranfer...

All depending on card speed of course... and to some degree on the Harddrive used, and even the power consumption of the individual memory cards, etc...

Self discharge rate? I'm not up on this, but it should be realtively low, almost not noticable during a short (month or so) trip. I'd have to do more research into LiION cells to give a more definitive answer, I've been meaning to research it, I just never got around too it.

If your speaking of the newer Nexto-CF/OTG model ND-2300, things are a bit differnt. The internal cell will yeild probably at least 60 mintues, I've seen 72 minutes with during a OTG transfer, which pulls more power then a CF slot transfer. The copy speed are slightly lower, but not really much differnt. The external pack for the OTG product , I'm not clear what it's total power capacity will be.
