HD with higher max transfer than 16.4Mb/s?

[Retrofan]

Hi:
This will be a short thread, but I want to know:
 
Why to put a HD with more than a transfer speed of 30Mb/s (that's the one of my CF HD)? Even the Fast Ata MKIII can't give higher transfer speeds than a theoretical maximum throughput of 16.4MB/sec
 
Does it make any sense to have higher transfer speeds on the HD?
 
I've found that if you want something faster than a CF and cheaper than it (for that speed) there's this:

ItemKingfast consumer grade 2.5inch PATA SSDInterface 44PINS IDE/PATA (1.5Gbps)Nand flash type MLC Capacity16GBPerformance Max transfer speed 1.5Gbps (150MB/s) Max read transfer 70 MB/s Max write transfer 40 MB/s Electrical Power voltage 5V ±5%
 
It costs only GBP 49,99 , the same that a Sandisk 16Gb one (with 30Mb/s), and it's IDE, 44 pins.
You woudn't have to buy the Cf-Ide adapter even.
 
What do you think?

You woudn't have to buy a Cf-IDE adapter even...

It's just fine and you're right about it.
Only disadvantage over CF is the size that's the same as an 2.5" IDE HD!

Btw... you should learn to edit posts instead of posting 1 line after another post

Sure? I though not, seeing the size of the 44 pins in the card
 
Edit: I didn't realice. I just though it and wrote it. Done
 
What about the max transfer over 16.4 Mb/s?

Pretty sure mate.
Check a normal 2.5" HD


...plus the screw holes under your SSD are the standard holes for mounting them.


As for speed...
I have never seen in my Amigas a speed test over 9.3MB/s and that's with BPPC's SCSI --> IDE via an ACard Bridge. HD is an 16GB CF.
Ofc with an UWSCSI HD on a Cyberstorm you could get a better performance... but NOTHING more than you can get with these SSDs.

For A1200's native IDE... I wouldn't expect something more than 2-3MB/s (without FastATA or Idefix Express) but even with the fastest IDE = (theoretically) FastATA.... I would be very surprised if you would succeed in achieving the MAX transfer rate at a PIO5 mode by using this SSD!

[Retrofan]

Yes, I see what you say about the size. Do you know the transfer rate though SCSI?

[Retrofan]

Ok, thanks. So, there's nothing better than the Ide-Cf adapter and using a CF like mine with 30mb/s (or less), as the max you can get using Scsi/Idefix/Fast Ata never will be higher than those 16.4mb/s, is it right?

[mfilos]

Yep, at least I believe so mate. I haven't seen speed over 16.4MB/s tbh, but then again, I never actually tried a real 10k SCSI drive to my former CSPPC's UWSCSI bus to be sure
AFAIK you'll be just fine with this SSD for every setup available (whether you'll insert it to an ACard SCSI to IDE Bridge, or use it plain IDE in Native/FastATA/Idefix Express)

only 50GBP? thats not cheap at all. you can get CF adapter and, say, 4Gb CF card for far less.
yes, 4Gb is a lot for some of us.
granted that ssd, might be more 'robust' as its designed to work as hdd.

another problem is that they are not easy to find. well at least not for me, and additional costs like postage and customs are not small. such a shame, I'd use one in laptop.

I agree they aren't cheap, but search a Cf with that transfer speed and compare prizes... It's 16Gb, not 4 ones. But it doesn't matter, I won't buy it. They are bigger and Why do I want it faster if the system doesn't use such speed? I just wanted to know, and it's a lot bigger than a CF...
If you want them, you can find them here:

All this speed info you give in your post is very interesting. I will keep it.
An Acard Bridge... that's really expensive. If you can't get more with that...
Everyday I discover something new: UWSCSI bus, what's that?

UWSCSI would be Ultra Wide SCSI (if I'm not mistaken) with a theoretical maximum transfer rate of .40 megabytes per second.
Not too defferent from theSCSI SPI-2 LVD drive controller I use under MorphOS.

UWSCSI would be Ultra Wide SCSI (if I'm not mistaken) with a theoretical maximum transfer rate of .40 megabytes per second.

At best it does on CSPPC about 30 MB/s raw read or a little over and real read/write operations about 20-25 MB/s. Pretty beneficial when doing backups with big drives. On small scattered files the copy speed can yet stay below 10 MB/s.
