This is of course in addition to the standard manufacturer replacement warranties. This means you can test drive the product in the convenience of your home. We will give you a 30-day, money-back guarantee on all our products. The Customer Guarantee lets you know what you can and should expect from Macfixit Australia -and what we’re doing to hold ourselves accountable every day.ġ. Caveat: the JVM for M1 Macs has to have native hashing implemented, or performance will be far lower.Our goal is to provide you with a consistently superior customer experience-whether at the initial purchase, during the shipping of your product and during the course of usage of your product. If so, icj will easily max-out the 7.4 GB/sec SSD I/O potential. FAST SSD FOR MACBOOK PRO PROJust how much computing 'juice' those 8 performance cores on the MacBook Pro M1 Max have remains unknown to me until testing, but I’m guessing somewhere in the 1100MB/sec range for raw hashing speed. It can also max-out a 2019 iMac 5K Intel Core i9 8-core SSD ~3.3 GB/sec SSD (each core can hash at ~733 MB/sec). FAST SSD FOR MACBOOK PRO MACIntegrit圜hecker Java (icj) can hash at over 12GB/sec on a 28-core Mac Pro. FAST SSD FOR MACBOOK PRO CODEStill, the code was improved and it’s a lot faster than in the past-it might benefit. In the past though, Photoshop took poor advantage of fast SSD speeds, well below what is possible. Programs that read or write very large files could benefit.But it won’t make your backups go faster reading at 7.4 GB/sec and writing to the same slow 200MB/sec hard drive. Gated by the slowest of the to/from drives. This was already the case in some Mac iterations, so it is not idle speculation. “Might” because paing is typically 32K writes and reads, and it’s possible that the faster SSD could be slower or no faster than the “slower” 3.3 GB/sec SSD for small reads and writes. Virtual memory paging speed when memory gets low might improve.Exceptionally well-engineered programs like Integrit圜hecker Java (icj), which utilize all CPU cores while overlapping I/O independently of computation (worker queues, multi-threaded file system scanning, multi-threaded parsing, etc).The good news is that there are at least some cases where the faster speed will help: Very few tasks can process data at more than 3.3 GB/sec, so 7.4GB doesn’t mean things would go faster in any appreciable way. Adequate CPU processing power for the data stream.And most such apps read in very small chunks. that app is crude from a performance perspective. A poorly written app that reads then computes and repeats-until-done. A well-written app is already overlapping I/O and computation for an effective zero-time disk I/O (rarely could data be processed anywhere close to 3.3GB/sec, so the I/O time is effectively free). Most disk I/O is intermixed with computation of some kind.Cutting the I/O time in half might might mean very little in the overall picture, where most of the time is computational overhead of other kinds: memory allocation, data structure setup, parsing, etc.Apps that make stupidly small reads/writes might still benefit, but nothing like maximum I/O speed. using very large transfer buffers, just for starters. Whatever application is reading or writing had to have special attention paid to maximizing disk I/O speeds, e.g. Several things have to be the case for 7.4 GB/sec SSD to outperform a 3.3 GB/sec SSD on real world tasks: Transfer speed depends heavily on transfer size Application behaviors FAST SSD FOR MACBOOK PRO FULLAnd since most apps use absurdly small buffers (1MB or smaller), they can never get full speed from the SSD. You need only glance at any of MPG’s test charts to see that transfer size matters hugely to speed. Next, a top speed of 7.4 GB/sec is *only* achieved for very large transfers. Once that cache is full, the overhead starts killing performance. How badly things are affected depends on the amount of memory 64GB will be worse than 32GB memory. That 7.4 GB/sec quickly gets cut back by this bug, unless macOS Monterey has fixed it. What is required for 2X faster I/O to matterįor starters, macOS has a performance bug that cuts ultra-fast SSD speed in half for the very jobs that could most use the speed. The next closest thing next is a ~2.7 GB/sec Thunderbolt SSD, like the OWC Thunderblade or OWC Envoy Pro SX. To know for sure, you’d have to compare using a 3.3 GB/sec SSD, and there is no way to do that (no external can go that fast, and no other internal SSD is possible). Does it mean much of anything will run a lot faster? Nope-a little faster for some things, notably faster for a few things, and not much faster for most things. Does that mean your Photoshop files will save twice as fast? Nope.
