With all the recent discussions about the 2013 Mac Pro, I was tempted to open my wallet and grab one for £180 GBP - including shipping.
Congratulations on the purchase. I had given some thought to purchasing one of the ones I linked to as they have a slightly higher configuration (D500 versus D300, 32GB RAM versus 16GB, and 512GB / 1TB SSD versus 256GB) then my current one. Since I don't use my current one I don't see any point to buying another one even if it is to obtain a higher configuration.

I’m more into anodised blue than red but those are freakin‘ gorgeous. :D

Yes, the blue editions are amazing, too! As is green:

This one has, almost, a robin’s egg mood:

Given the way the 1980s slab period was right during when pastels and de-saturated hues were having their moment, I would have loved to see more vivid blue and green variants. (The frequency of solid red appearing for several of Sony’s limited edition variants is, of course, self-evident.)

A blue, for instance, might have more closely resembled the much later anodized blue of the Handspring Visor Edge:

A peculiarity with the TB1 dock is that the FL1100 gets one 2.5 Gbps PCIe 1.0 lane there (even though it’s a PCIe 2.0 device) which may help explain the abysmal performance. If it connects using PCIe 2.0 in the TC I‘d expect it to be faster there (5 Gbps; 400~450 MB/s or so?).

You are correct (as ever) it uses 2.0 in the TC with 500 MB/s max according to what's written here and quoted below but very likely 400-450 MB/s in practice. :)

The 8th PCIe lane off of the PCH is used by a Fresco Logic USB 3.0 controller. I believe it’s the FL1100, which is a PCIe 2.0 to 4-port USB 3.0 controller. A single PCIe 2.0 lane offers a maximum of 500MB/s of bandwidth in either direction (1GB/s aggregate), which is enough for the real world max transfer rates over USB 3.0. Do keep this limitation in mind if you’re thinking about populating all four USB 3.0 ports with high-speed storage with the intent of building a low-cost Thunderbolt alternative. You’ll be bound by the performance of a single PCIe 2.0 lane.

Do you have a USB 3.0 SSD to see how fast it will go on the TC?

Absolutely! There's the spare 870 EVO that can be attached to a USB 3.0 to SATA adapter.

What do you have in mind?

The TB3 dock‘s USB 3.0 controller (which one is it? System Profiler will tell under PCI cards) probably uses a single PCIe 2.0 lane and shares that 5 Gbps bandwidth among all of its ports too.

Ventura offered zero information on my 13" 2012 MBP, so I switched to the TC and High Sierra where slightly more details became available.

This is all that I could find within PCI information...

...is that the TC's onboard Fresco Logic controller or the TB3 dock's?

Edit: just spotted your update. :D

You can always install Windows 10/11 or any Linux distribution... if you want.

I've already got Win 11 on a PC and Linux could be an option as a dual boot but the idea of buying a Mac to primarily run another OS instead of macOS has never appealed to me.

Congratulations on the purchase.

Thanks. :)

How come you're not using the current one? Apparently they can be upgraded cheaply if you want to improve the spec. Just throwing that possibility out there.

I feel the same way.

I just don't use my Macs as much as I used to, the only one which sees occasional use is my 5,1 Mac Pro and possibly my 2012 13" MacBook Pro. I bought the 6,1 as I like its design but it was replaced with an M1 Studio Ultra (which also rarely see use). I recently acquired a 7,1 Mac Pro as, IMO, it represents the last of the truly expandable Macs (unless Apple rethinks their current strategy).

Sadly Apple is no longer the company which makes products I used to love using.
 
They look like your USB to SATA adapter is limited to 3 Gbps (which chipset does it use? Try System Profiler‘s USB section).

This is what I found:

USB 3.0 Bus:

Host Controller Driver: AppleASMedia1042USBXHCI
PCI Device ID: 0x1142
PCI Revision ID: 0x0000
PCI Vendor ID: 0x1b21

Ext. HDD:

Product ID: 0x0611
Vendor ID: 0x1f75 (Innostor Co., Ltd.)
Version: 0.06
Serial Number: 20240222
Speed: Up to 5 Gb/s
Manufacturer: Innostor
Location ID: 0x01100000 / 1
Current Available (mA): 900
Current Required (mA): 800
Extra Operating Current (mA): 0

They appear to be these chipsets:

The TC‘s FL1100 performs better than in the TB1 dock though. :)

Here's the results that were achieved with the TC's FL1100 and the following USB 3.0 enclosure hardware:

Product ID: 0x1337
Vendor ID: 0x152d (JMicron Technology Corp.)
Version: 5.08
Serial Number: 7F833EEF5DC0

Much better but not great.

I tried to carry out a test with the Kanex TB dongle and the JMicron based USB 3.0 enclosure but the pair wouldn't get along - Ventura's Finder reported in a loop that the SSD was being ejected unsafely and remounted. The behaviour was identical in High Sierra. This was a shame but I managed to test read/write speeds with the TB3 dock:

Slower read/write speeds via USB on the TB3 dock than the TC's internal USB ports. :confused:

There's one more TB3 dock that I could test but it won't work on a TB2 equipped Mac unless its daisy-chained at the end of another dock... As a matter of thoroughness, I could test the 870 EVO in my 5-bay USB 3.0 enclosure if you're curious. :)

Fair enough. Out of interest, how much did you manage to the obtain the 7,1 for?

Unfortunately, the odds of Apple changing direction appear to be slim. They're quite content to sell disposable products in the vein of seasonal fashion pieces.

Sadly Apple is no longer the company which makes products I used to love using.

I wholeheartedly agree with you and it's highly likely that the same applies to most of the other PPC/Early Intel Mac forum members.
 
This says the Innostor IS611 is indeed limited to 3 Gbps SATA. :(

Such a shame but it remains useful for working with PATA/IDE stuff. In future I'll pay closer attention to chipset specs.

384 MB/s isn’t too bad.

Then I won't whine too much about the TC's USB capabilities. :)

Does the JMicron enclosure perform better on a Mac/PC with native USB 3.0 (if you have one)?

Excuse my obtuseness here. I'm confused, as I have a PC and Macs with USB 3.0 - including my new toy.

I bought it for $1,650 configured as follows:

  • 16 Core processor
  • 96GB RAM
  • 2TB NVMe SSD
  • Radeon Pro 580X
I got it from iPower Resale which has a bunch of these systems. I saw it on Ebay (I think I posted about them in the Mac Pro forum) but bought it directly from their online store:


Mine was a Grade-A quality Mac so it looks as if prices for that grade have increased somewhat (though in order to get the $1,650 price I negotiated with the online sales assistant so anyone thinking of buying one should give that a try). A Grade-B looks to be selling for $1,450.

I meant to ask if the SSD in the JMicron enclosure is faster when connected to a system that has USB 3.0 ports provided by the chipset (rather than by an external PCIe controller).

That will require a marathon of testing. The candidates would consist of my following gear:

  • 15" 2012 MBP.
  • 13" 2012 MBP.
  • ERGO i7 PC w/ Win11.
  • 2013 Mac Pro.
They all qualify as they have onboard USB 3.0 chipsets, right? This would exclude my 2006 MBP as it has a PCIe card.

It'll take me a while to work through them all. I'll get back to you on this one. :D
 
I‘d just test using the newest system to hopefully get the highest results. (The TC doesn’t fit the bill as it needs the Fresco Logic thingy for USB 3.0.)

Thanks for making things easier for me. That was very merciful of you. ;)

Alright, that means the best candidate will be my 15" 2012 MBP.

Actually, no - it's the i7 Win11 PC! (I'm too biased towards Macs. :oops:)
 
The FL1100 USB 3.0 is a PCIe gen 2 x1 controller. USB 3.0 is limited to 4 Gbps (after 8b/10b encoding). PCIe gen 2 x1 is also limited to 4 Gbps (after 8b/10b encoding) but it maybe has more overhead than USB so you won't get full USB 3.0 speed from the FL1100. If you have a Thunderbolt 3 dock, than a USB port that supports 10 Gbps (such as the downstream Thunderbolt port) will probably get you better USB 3.0 performance than a USB 3.0 port.

Understood.

Ok, if I'm following everything properly, a Thunderbolt 3 dock with USB 3.0 ports connected to the Mac Pro will outperform its built in USB 3.0 ports? In the above tests, the TB3 dock yielded worse results. I do have a HP TB3 G2 dock but it won't function with my Macs unless its daisy chained after another dock.

I should probably spin this topic off into a separate thread because it's no longer eBay bargains related and has become a specific technical issue. :)
