External CD/DVD drive

A friend has a need for a high speed external drive to read CD's as fast as possible. It plugs into a Raspberry Pi based device and we are not confident of the usb power available.
He bought a non-usb powered LG GE24NU40 from Amazon UK, which was shipped from the USA. After about 2 weeks it has failed. He called Amazon, who said it would have to be posted back to Kentucky at his cost. If they agreed it was faulty, his costs would be refunded. The Post Office have told him the postage cost would be over ?20, so he is now considering his options.
He has tried an external usb powered drive, but that is nowhere the same speed and looking at the drive in it, it is the same model as in my ancient Lenovo T410 laptop. The LG drive is rated at 48x for CD's.
I have had him check the psu that came with the drive, and it is rated for 110 to 240 volts. The drawer opens and closes, but no CD's are detected. I have got him looking for his CD cleaning disk.
I suggested he looked for a UK source of a similar drive, but no-one seems to sell anything but usb powered ones now.
Does anyone have a suggestion for a decent high speed non-usb powered external drive? I don't want to suggest buying a case and internal drive, as I'd have to drive over to him to assemble it.

Presumably because the Raspberry Pi runs Linux and networking two Linux machines together is both simple and fast.

I wouldn't be surprised if the Pi can't run the drive at full speed anyway. It can't run anything else at full speed not even on the 3b+ I have. They are nice devices but quick they ain't.
anyway..

Thanks for the pointer to that enclosure. That didn't come up in my searches. I had seen one or two more expensive ones priced from over ?50 upwards, which seemed excessive.
Internal drives are not the problem and I know that many of the 24x writers will read CD's at up to 48x.
With his failed drive all I can say is that until it died he says it did read a CD in 3 minutes as against 10 to 30 minutes on his 2 smaller drives.
I am not sure why there is such a speed difference, maybe bigger cache or just better read quality. I don't know whether his device has any check of the quality of each rip. I do know that in tests on a laptop here, dbPoweramp is quicker than EAC, which I understand is because dbPoweramp just checks quality against a database, rather than making multiple passes to check for consistency.
He is going to post the drive back tomorrow, hope for the cash refund in the fullness of time, and probably will order another of the same type again from Amazon. He is hoping he just got a bad one.

If you can find one of the one of the Optiarc DVD/CD writers, then the are very quick handling CDs - also particularly so on audio extraction which lets down many of the drives which are quick reading data CDs.
I have some of the 7240S drives and they will rip an *audio* CD in about 3 mins using EAC.

About 6 minutes using iTunes and a portable USB2 Samsung drive on a reasonably quick computer.
Either way, it's going to be a long haul ripping (maybe) 500 CDs. Then there's hoping they're in decent condition and copy over nicely, catalogued and gaplessed correctly. And then there's the backup . . .
If pushed for time and not strapped for cash, or not wanting to do such a mind-numbing exercise, I'd think about posting on a local forum - see if anyone's interested and how much they want. I'd think it'd be 50+ hours.

We are told "He has about 1TB of flac files stored the last time I looked, and is about half way." Assuming a CD compresses to a FLAC of 400 MB on average I make that 2,500 done and the same to follow!

Though it doesn't take many CDs with problems which lead EAC to take an hour or more for the job to stretch.

I am presently re-ripping my CD collection as FLAC, having previously done them as MP3s (which was a mistake - I should have bought more disk in the first place). FLACs are roughly 10 times the size of MP3s. About 1% of my CD collection is proving to be unrippable, despite having previously been OK.

Commenting on the 3 previous messages in this thread :
Yes, the Optiarc 7240s internal drives seem to be about the same speed as the external LG drive that has failed, and would be ideal for him if they were external usb drives. I do notice that the Optiarc slim drives for which cheap usb cases are available are rated at half the speed of the 7240s's.
My tests here, ripping a CD into a laptop, showed that using dbPoweramp took something like 5 to 6 minutes, EAC took longer. The laptop drive, and my external drive are both slimline. My understanding is that dbPoweramp uses a database called Accuraterip to check rip quality, whereas EAC does repeat reads (and may also check with Accuraterip) to get the best quality possible. This may exceed the "quality" of the tracks in the AR database, or not.
My chum has in the tens of thousands of specialist CD's, some being non-commercial CD-RW's of music and events he has been involved with over the years. His aim is to get the best of this findable on this "Brennan" device and easily accessible via his lounge hi-fi system with control via a Surface tablet laptop from a comfy chair. He is nearly there, but has had disaster after disaster. I think he has about 3,000 done to date.
Over the years he has converted from open reel to DAT to CD, so he is used to having to move forward.

No!
He has already reloaded at least once from a backup following at least one of the disasters. He backs up to a portable hard drive and also to his main desktop PC. Backups can be incremental or full, and he is aware of how to initiate either.
This may not be ideal, but so far it has worked.

Ah, yes, well spotted! Well, that's just going to take months - I estimated a long working week on 500. Not that my estimates are much to go on ;-)

TBH, a friend took all of my 500 CDs (and nice pine storage cases) - she kept them on condition they were ripped to flac for me.

Probably also worth searching round people you know who may have already ripped a common subset of disks you own.

I found doable using a couple of machines and 4 drives.. run a couple of instances of EAC on each machine. It keeps you busy enough uncasing, loading, ripping, onloading and recasing disks etc... I did batches of about 90 disks at a time.
It helps if your music collection is something for which you can rely on the catalogue databases to identify and name the tracks etc. Something that can be less successful on some classical recordings.

If he bought the drive through Amazon UK then his contract is with them and he should send it back and get a refund. If Amazon choose to ship products direct from a manufacturer that is their problem not his. If he has someho w managed to make a purchase from Amazon US then it is "caveat emptor" I am afraid.
