SCSI2SD Speed Benchmark

Thanks to PCBWay.com
The SCSI2SD is a solid state alternative to mechanical SCSI hard drives. Focused mainly around the use in vintage Macintosh computers, this benchmarking video finds out just how fast the SCSI2SD really is!

"I did it so you wouldn't have to" - and I'm very grateful indeed!

[@lagmagnet]

Absolute legend, thank you, Bruce! Fellow Australian 7600/200 + G3 upgrade owner here, and you've just convinced me to spend the extra on a V6 to replace an ageing drive. Greatly appreciate the effort you've gone to and the way you presented the data.

[@TheAMGReviewers]

I neither own nor intend to own anything with SCSI or "dated" tech, yet I thoroughly enjoyed this content and delivery. Many thanks :)

Love This Video and It really Answers all the Questions, Fantastic Bruce!

[@nathanfulton]

Thanks for the hard work on this!

[@michaelweare9839]

Another quality review - clear and concise. Thanks Bruce

[@MrKrimstah]

Love the video Bruce , please do more content like this

[@rjpeterson1]

Great analysis Bruce!

[@1magazine]

Oh wow really looking forward to this. Glad I didn’t yet order new ones until I have all the benchmarks 😊

[@edretrotech7559]

Nice comparison video, Bruce! I loved the * spoiler alert * classic FPS cameo at the end :)

[@mingohagen]

Nice job!

[@RonsCompVids]

Can't wait!

[@michaelsworkshop9031]

Thank you, Bruce!

[@glonch]

Well done... a ton of work here...

[@threethousandyen]

This was great. Would love to see a tutorial about how to transfer stuff from a SCSI2SD back to a modern Mac in the future.

[@CrazyTechReviews]

Nice Bruce! Like the smash that like button touch!

[@jameswhite2792]

Thank you for another really interesting and thorough video. Your videos are always excellent and have taught me a huge amount! For me, the SCSI2SD is about convenience. Here in the UK, I've picked up some newer 10k 2.5" SCSI drives, terminators and adaptors that work well in all Macs for less than a third of the price of the cheapest SCSI2SD. And the spinning drive outperforms my SCSI2SD 5.1 on nearly everything that matters (boot times, read/write speeds etc). Of course, the spinning disk adds more strain on the power supply, adds heat and a little noise as well. The SCSI2SD is an absolutely great product, but at the price it's not the only solution. If you have a lot of Macs, it gets very expensive, very quickly. I love mine as an external device for moving files between systems.

[@paulie-g]

Out of curiosity, what were those newer 10k scsi drives? It's a bit tricky figuring out which ones will work on the 8-bit Narrow SCSI in 68k Macs.

[@PCBWay]

You did it pretty great, bruce, cheers 🍻👍

[@achimboers]

Love how everybody says pcb waayyyyy

Thank you for saying out loud that SD cards are not SSDs, spent way too much time shouting at KZbin when I hear SDs being used as a "solid state upgrade"

[@angrydove4067]

Wow, you put a LOT of work into this video, I have the V6 and now want a V5.5! Hey, if you put your cat in all your videos, you'll hit 100k subscribers in no time! Thanks.

[@therenderer4726]

Hi, you stated that on the SCSI2SD v6, the first drive is only mounted on the Mac. Which revision of V6 do you have and do you know if they changed this on the 2021 revision and all drives can now mount from the one SD card? Thank you.

[@W62315]

For comparison, some v6 benchmarks on SGI workstations forums.sgi.sh/index.php?threads/scsi2sd-v6-performance-report.110/post-1020 TL;DR -- Even when matched up against a top-tier 15K RPM disk the SCSI2SD is faster. Also substantial performance improvement with Sandisk Xtreme cards in the tested systems.

[@johnkyd3977]

Great watch Bruce. Now grab another v6 and another extreme card and raid em up

[@ARGON023]

Hello, I bought SCSI2SD v6. I have ATARI TT and FALCONA030. Is it possible to supply power to SCSI2SD via the output of ATARI floppy disk power supply with SCSI2SD floppy disk input. Currently, I can only connect via usb computer - SCSI2SD v6 2020c, I have two more power adapters to charge the phone also with a 5v usb output. one has 460mA and the other 1.2A. The SCSI2 instruction states that the power supply cannot exceed 500mA and 5V, especially the problem with the 500mA current - no one on YTub addresses this problem, hmm, how to connect SCSI2 from a loved ATARI floppy drive or from a converted USB output from with 2A and 5v current? Can I ask for help with the solution NOT to burn SCSI2SD chips.

[@suadcokljat1045]

And now when SCSI2SD is no longer available, it would be great to compare it to ZuluSCSI and BlueSCSI. Cheers, S

[@cube1us]

I'd have been interested in seeing *write* tests as well.

[@BranchusCreations]

The final score includes reading and writing.

[@cube1us]

@@BranchusCreations The score is nice - but I wanted to compare write speeds with what I see for the BlueSCSI F4 adapter - score doesn't help there.

[@JoeGoesx]

Hi, Power Macintosh 8600/250 with SCSI2SD V5.2 is there any way to format the SD card over 4GB to use with Mac OS 9.x? alternative to HD_SC_Setup_7.3.5_Patched

[@BranchusCreations]

I would recommend using the OS9 Drive Setup rather than the old HD SC setup. You should be able to format bootable partitions all the way up to 128GB.

[@JoeGoesx]

@@BranchusCreationsThank you for the reply Bruce, I get "Cannot initialise disk on unsupported drive" hence the reason I’m using the patched older version. And on windows 10 when I save a config using Scsi2sd utility the next time I plug the adapter in everything is back to default.

[@thorstenrehling2668]

Hi you can use the FWB Disk Tools to format nearly every kind of drive . I use Version 3.0 but 2.5 works although fine. It was „THE“ disk tool in the 90s like a Swiss Army knife 🥳

[@megaimg]

What about 5.1 with the DB25 Connector to use it externally...Will be interesting if it better that 5.5

[@BranchusCreations]

It was my intention to test this, but I broke my v5.1. As soon as I fix it, I'll do this test.

[@megaimg]

@@BranchusCreations Thanks sir! Will be interesting is the performance is better externally than the 5.5. By the way Excellent job like always!

[@AnonymousFreakYT]

You didn't show the write speeds of the later SCSI2SD models, only when first showing the benchmark. The write speeds are what really interest me - could you either just post screenshots of the whole results for each model, or at least list the write speeds?

[@BranchusCreations]

Sure, I'd be happy to. Do you have MacBench v4.0? I can just send you all the result files if you like.

[@AnonymousFreakYT]

@@BranchusCreations I do indeed, that would be good! Email my KZbin user name (with no space/period/break) @ Apple's-consumer-email-cloud-service. Or send to me on MacRumors Forums (same user name/icon.) I'll even compare to a few more vintage hard drives and post the results. (I only have a SCSI2SD V5.1, and was specifically wondering if the V6 is fast enough write speed for what I want to use it for.)

[@W62315]

Not on Apple systems, but lots of write data for the v6 here: forums.sgi.sh/index.php?threads/scsi2sd-v6-performance-report.110/post-1020

[@cursedfox4942]

I mean all we want to know is mb/s sustained not all these score shenanigans
