Sandisk Extreme Pro 240 GB SSD.

[Protools5LEGuy]

The Sandisk Extreme Pro 240 GB SSD  cost me 104 EUR

How did you partitioned it?

Volumes over 190 Gb ... are imposible to defragment.

Is defragment needed on SSD?

[MacTron]

How did you partitioned it?

With the standard Apple Drive Setup 2.1, as any other drive ...

Is defragment needed on SSD?

No, it's not so needed as an ordinary hard disk, but you can always defragment it by the "simple way" (reformat and carefully copy back the content in the proper order)

Is defragment needed on SSD?

As stated before, all blocks on an SSD read/write at the same access speed so defragmenting is..
1) Useless
2) Will shorten the SSD life (over time) with unnecessary read/writes

[OS923]

so defragmenting is..
1) Useless

File fragmentation always wastes memory and speed.
When your Mac starts up, it copies the entire directory into memory plus the info about the first 4 fragments of each file.
If it needs to know something past the fourth fragment of a file, then it has to access the disk.
If it accesses the disk, then it will swap pages in the cache.

OWC Mercury Electra 3G 60 GB,Internal,2.5" (OWCSSDEX3G060) Portable

I Just bought 5 of these new SSD drives for $25 each...lol

Specs on these are very good (should be the exact same kit used by OWC for Legacy G4s

I suggest you get yours too     Why are you still reading, get one now !

[mrhappy]

OK DieHard...I ordered four of them!

[DieHard]

Well, you gotta be happy about that

[mrhappy]

Yes indeed!

[OS923]

An SSD isn't ideal either.
They can become unusable because of a simple power outage.
As they get fuller, they become slower to find a free block.

I read about SSD on Wikipedia and became very pessimistic about them.

I read also about harddisks with a glass platter.
They can store 365 TB on a 1" drive.
The data is preserved for 10000 years.
They will be extremely reliable and extremely cheap (price per GB).

Most of today's Laptop Hard drives platters are coated glass already...

[OS923]

I mean glass without coating.

Are you referring to the ones that use a laser to do holographic etching into glass for storage?
If so have they improved the performance.  Last I heard the write speed was somewhere in the less that 512 Bytes per second.  Read was a bit faster.

240 GB Patriot drives are reasonably priced here, after the mighty 27% sales tax (can claim it back!) they cost probably less than in the U.S.
I think I will get six of them in next few days among a pair of 1TB Samsung EVO 970 Plus and get that 27% back before the holidays.

According the fee-Bay my PCI-X SAS card for the upcoming G4 project was shipped today form Russia and the 2 GB memory (4x512MB) from the States.

What I miss now is "just" a video card for MDD which can drive a 30" monitor. Will assign a pair of "Patriots" to that machine, the rest for all kind of boot-OS on the 2009-2010 "Cheese Grater"-s.

It's quite nice being able to swap the drives for the test quickly.

As for "9"... looked at it today, after 15+ years again. The poor MDD has only 256MB memory. And the video card can't even drive the monitor I want.
Still, it looks quite refreshing compared with the 10.13.6 I am using with a "trash can". I sure will miss the 42" monitor on the MDD... 30" would be nice.

As for 27% sales tax... There is only one country in the world with that groovy tax.

You are the hackers, for half of decade you tried to crack my firmware... And you still do not know? It's all there, inside!
Just pay attention to small detail. It's also part of the copy protection.

i just bought the Samsung 860 EVO
 

256Mb ram on an os9 machine isnt as bad as it sounds
os9 doesnt need much ram compared to osx or windows (xp, 7)

ram for a g4 is cheap as hell if not Free at this point

Got 2 GB RAM from the States and the SAS card from Russia.
The 2 GB RAM works fine, the SAS card unfortunately is for G5 only.

 Stupid me, did not pay attention that the card voltage is not compatible with G4, only with G5.
Otherwise the card is good - but the bad news: no SAS driver for MacOS 9, unless there is somewhere an LSI SAS card which fits the G4.

The number of such 64-bit cards is quite limited:

- All Marvell 6042, 6084, 6081 based cards. The best chip is 88SX6042
- SImage 3124
- "Frodo" Broadcom 5770, same chip as sold inside of G5 under nickname of "K2"
- The known and very much limited in numbers Intel / Vitesse 7184
- Many LSI Fibre cards! They do not have MacOS 9 SIM, but the LSI architecture is very open, writing a SIM is feasible

The most common 64-bit card is either SImage 3124 or the Frodo. Frodo is even cheaper and I have the full programmer's manual for Frodo, flashing included.

For starters anyone can buy a Frodo card of eBay

https://www.ebay.com/itm/Broadcom-RAIDCore-BC4000-Series-SATA-RAID-Controller-Card-BC4452/183381200702

and modify the K2 driver's plist (for hackers) or just change and compile one from open source (Darwin) for programmers.

Try the above card for offering the seller 15 Bucks.
You can't get wrong on that.

The FCode would be easy: it has both advanced SATA and regular quasi-ATA interface.
For FCode the quasi-ATA interface is perfect, I think Apple does use it in their K2 code, they don't go more "native" than that.
For MacOS-"9" a quasi ATA still better than nothing.

Frodo is perfect for an extra 2 drives inside and 4 going outside.

noones going to buy that stuff unless they know its possible to get it working
noone has the skillset or experience that you have

Thanks - but looking today at my 3124 code from 2005 I see how bad it is.
I do have a Frodo and luckily I found the entire documentation in an old email.

Since 3124 is in very advanced state (it needs few days of update and clean-up on "X", nothing in FCode and porting "X" to "9") it makes the biggest sense now.

3112 and 3114 would be even easier - if not the problem with the Micrel regulator. That regulator spoils all the fun.
Even 3112 cards made by Adaptec have the regulator problem.

I will "open" both 3112 and 3114 ultimately but they will be maybe even after Frodo: Frodo is cheap, there is plenty, it is 64-bit and has at minimum 4 ports, at maximum 8.


So the plan for this year is 3124 first, than Frodo.

Thanks for keeping us mere mortals in the loop... you have our support 1000% !!!

this could be a godsend; literally; for the retro mac g3/g4 users of the world
