The external PCIe will be cheaper and easier because it will be hosted directly by the mobo chipset, or the CPU by tapping into already existing hardware. but we have not seen that happen over the copper version that was released. It can send PCIe, it can send DP, it was supposed to be able to send USB 1/2/3, as well as Ethernet, all over the same wire. You think the specification will somehow make things cheaper? Nope.thunderbolt is a medium that allows for multiple interconnect protocols to be transmitted over the same wire. However, LaCie's Little Big Disk is more effective with its two SSD 320s than Promise's R4 armed with four SSD 520s when it comes to random performance.
Achieving better random throughput is important for certain applications that a hard drive-based solution simply cannot address. In theory, sequential performance should speed up by 5-10% (50-100 MB/s), while random I/O improves by an order of magnitude. Next to the R6, its benefits are likely to be limited. What this quad-SSD R4 variant might offer will depend on what you compare it to. A single 240 GB Intel SSD 520 runs just north of $300, so a four-SSD variant of the current R4 could conceivably weigh in under $2000. Using the current 4 TB R4 as a baseline, we assume the 1 TB Hitachi 7K1000.D Deskstar hard drives are about $100 each, with the chassis and components totaling about $750. We don't have an estimate for what the R4 with solid-state storage will cost, either, so we were forced to create our own estimate. I do prefer the form factor of the G-Speed with the built-in handle but it's not a dealbreaker for me.Promise does not anticipate selling an SSD-based R6, stating the added cost of six SSDs would would push the price of the R6 beyond what the market will bear.

It would be unreadable on the mac until this was done, so if you only have a mac, I would add that to the list of things to be cautious about.

This then needed a very laborious fix where I would have to plug in in to a PC (I mainly work on a Mac) then fix the errors on the PC, then re-attach it the the Mac. I also had a few occasions where the G-Speed would completely corrupt itself if it was accidentally unplugged whilst the machine was still on. I found the G-Speed to be constantly "clunking" as the heads moved about whereas the Promise was overall, much quieter. Noise-wise, the tower sits on my desk so the quieter the better. I had a few cases open with G-Tech but nothing came of it, they were no help. Although I realise that most of these type of RAIDs are optimised for larger files, the Pegasus did a better job. For example I found that copying things like TIFF sequences or multiple smaller video files (like GoPro or other minicam etc) would slow the G-Speed to a crawl.
The main reasons I prefer the Pegasus over the G-Speed are the lower noise and the better performance when dealing with smaller files. If you do decide to do this then you can see my posts on their forum that describe and link to the process of doing it. The process of replacing the drives was very straightforward. I bought 24 of these and 3 more for spares in case I needed to swap out a failing drive (so far, all good).

I think the largest on the list is 16TB.įor me, I replaced the 4TB drives that mine shipped with, with 8TB Toshiba drives, specifically Toshiba Enterprise MG Series SATA drives - item code is MG05ACA800E - I believe this is similar to what I bought. It hasn't been updated in a while but that shows you the drives they've tested it with. Hi, so I used the Promise compatibility document on their website to make sure I was using supported drives.
