Mods, if this is the wrong forum my apologies and please move it.

 

Hi all,

 

I'm looking for a PC card that will plug into a regular motherboard PCI-E 1X slot and provide a "hole" in the rear for a Compact Flash card (see attached concept image).

 

I've searched Amazon and Google and can't seem to find what I'm looking for. If anyone can point me toward a card like this I would greatly appreciate it.

 

Thank you!

Not exactly what you want but close, CompactFlash to SATA adapter.  You should have extra SATA ports.  But if not, you could easily find a second PCI-e to SATA card to pair with it.  https://www.apro-tw.com/apro/2.5...

Don't forget google image search. Your image is shown there as appearing xx minutes ago.  Several front panel drive bay units with cable to PCI-E appear.

Thanks for the suggestion, but it won't work because the machine I want to use it in has all 6 SATA ports used.

 

It's a RAID-6 file server with six 2TB drives in it providing 8TB of storage (RAID-6 "uses up" two drives, but can withstand up to 2 failed drives without data loss).

 

Currently the server boots from a 16 GB USB thumb drive. The entire OS is on the thumb drive, and all the data is on the RAID array.  But, the thumb drive is S-L-O-W and I figured that a Compact Flash card (on a fast PCI-E bus) would be much better.

 

What I really want is the ability to pull out the OS storage and work on it on my own computer (update the OS, make a backup, whatever I might need to do).

 

A long time ago I used to do all that stuff remotely via SSH and one day I made a boo-boo and blew away all the data on the array.  Working on the card physically removed from the server will limit the chances of another disaster.

 

Everyone asks "What? You didn't have a backup?"  Yeah, right... how do I "back up" 4TB or more of data?

Tried that - no success.

 

And, the image I posted is a "composite" with a CF card cut-n-pasted onto some other PCI-E card. It's just an image... doesn't really exist.   smiley

Does it have to be PCI-E ?

 

There are plenty of USB-connected card readers ...

  2. "Garbage" characters on a serial terminal are (almost?) invariably due to wrong baud rate - see: https://learn.sparkfun.com/tutorials/serial-communication
  3. Wrong baud rate is usually due to not running at the speed you thought; check by blinking a LED to see if you get the speed you expected

If yes then add a PCI-e to USB 3.0 SuperSpeed hub xHCI 2-port card.

Blu-Ray BD-R quad layer is about 120GB.

In addition, maybe the BIOS or UEFI can boot from DVD; otherwise, update the server's motherboard.

I think you would be better off looking for a faster thumb drive...  I've noticed a significant difference even among the low-end drives I tend to buy, and assorted benchmarks show over 50:1 read speed differences:  http://usb.userbenchmark.com/

(I don't see benchmarks for using it as a boot device, though.   That may be dependent on your BIOS as well as the flash drive.)

 

Some of the "PCIe Flash readers" I found look like they probably go PCIe->USB->CF rather than direct to CF.

I did see some PCIe to ExpressCard adaptors that look like your picture, and then you can get ExpressCard to CF.  $$$, though, for uncertain performance.

 

 

how do I "back up" 4TB or more of data?

I "splurged" for a 10TB drive just for Time Machine.  It's currently using about 8G, so I still have breathing room.

I noticed 5TB Portable (2.5inch) USB hard drives as costCo today.  That's a bit ... boggling.

Long time ago in a galaxy far, far..... (nope... this galaxy) in 1970-something, a friend of mine and I build a digital identifier for one of the local 2 meter repeaters.  The repeater used to use a tape loop to send the audio morse code for "DE WR2ACA" for periodic station identification as required by the FCC.

 

Well one day the tape thing died and we at the club decided the new one should be digital.

 

So my buddy and I built a 10 X 10 (100 bit) diode matrix ROM which used (if I recall) 7490 decade counters, 7445 BCD to Decimal open collector decoders and a 556 (dual 555), one for the clock and the other for the audio tone.

 

There were ten "X axis" bus wires on one side of the perf board and ten "Y axis" on the other and we soldered 1N4148 diodes across each crosspoint where we wanted a "dit" (or three consecutive crosspoints for a "dah") and no diodes for silence.

 

There was also if I recall 7402 quad nor gates... some to form a set/reset latch and the others to combine the crosspoint logic into an output that drove the "beeper" half of the 556 timer.

 

All we had to do was momentarily pull a line low, the S/R latch would flip (keeping it on) and it would clock through all 100 bits then when a 7490 overflowed, it reset the S/R latch. Worked like a charm.

 

Anyway... why am I telling you this? Because my buddy and I spent a lot of time on the phone discussing how exactly to design the thing and we realized that it was a 100 bit ROM.  So I jokingly said (at the time) "Someday they'll have multi megabit memories" which I thought sounded beyond belief (and the M-M-M words had a funny ring to them).  This was at the time that we had 1024 bit 2102 memory chips and anyone seeing an entire KILOBIT of memory in one package made their jaws drop open with amazement.

 

Now we have gigabytes to terabytes (remember - bits times 8!) ecthed on a little 3x3 mm silicon chip embedded in a small piece of plastic with 4 gold fingers and that's a "thumb drive".

 

Amazing as that is. Moore's law hasn't shown any sign of faltering. What will we have in the next 10, 20, 30+ years?  It's mind blowing.

Well..... the problem with that idea is that the motherboard (an old Intel Socket 775 board with a Q6700 Quad core CPU) only has USB 2.0 ports on it.

 

There is a USB 3.0 adapter card plugged into the mobo, but it isn't active until Linux boots and loads the card's driver (therefore can't boot from the card using a faster USB 3.0 thumb drive because, to the motherboard, it doesn't "exist" yet).

 

If I ditched the old mobo and built a newer server, then I would end up buying larger hard drives and lots more parts and spend a lot more $$$ than the problem is worth.

 

That's why I thought a simple PCI-E card plugged into the mobo with an externally accessible CF card slot would be ideal. CF cards are WAY faster than USB thumb drives. 

 

I could even splurge and buy one of those "industrial" CF cards that use SLC flash memory (which is supposedly faster and much more durable, data-wise) and it would cost a lot less than a whole new computer.
