Areca vs softraid
For now, some 6TB drives? And when it comes to SoftRAID 5 mirrors, use three drives for a mirror not the minimum of 2.įor the PCIE upgrades here's a partial plan based on your responses:
PS: You need something much much more reliable and stable than TimeMachine!! CCC definitely but also a mirror RAID6, two arrays of your proojects and media when the size and value and access/speed is critical and you get into larger volumes. And there are other boxes of course that can run non-Mac OS but have plenty to offer. The 6,1 nMP is looking "old" at nearly two years.

Highest density drives like 6TB are fast, especially if you cut them in half! and use part of the drive (and can grow into using full drive later if needed). GPU: GTX 980 EVGA using two 6-pin power connections.Ī couple blades and use SoftRAID 5.x for all your drives. I would think 64GB is not ideal in your environment. And no to OWC controllers! or their SSD device.ĭual 3.4GHz 6-core maybe? 56xx support for 1333MHz RAM as well as people have found there is support for 160GB RAM.
External RAID6: then yes with Areca or ATTO or whoever has the crown currently. No support for 4TB and above, lots of -problems, and not a good use of your PCIe slot. I have no respect for the Apple (Pro) RAID card. I would drop the idea of using SATA II with SSDs unless you want large SSD volume (JBOD) for some reason. The cMP will be held back by not having PCIe 3.0, and sometimes balancing two blades (using slot #2 and #3) does not double thruput.

_PCIe adapters instead of controllers can send and shuffle data into and back from memory faster.īlade type SSDs in classic Mac Pro offer 1500MB/sec. The PCIe-SSD blade (Apple-Samsung 1TB, XP941 or SM951) devices are "game changers" and the easiest way to get past the current IO bottlenecks. Take a look at site references, he is VAR but also high-end photographer and has excellent ideas to optimize and configure I'd like internal redundancy and external Time Machine Backup. I would also like very fast access to my photo libraries. Genomic data sets can be up to a terabyte. I'd like blazingly fast access to genomic data for I/O, both sequential reads and writes as well as random I/O. I'd like all my highly accessed data organized well and onboard my home directory. I am a scientist and photographer and my use case is basically 50% big data (genomics, remote sensing) workstation with parallel processing and disk I/O important (possible use of CUDA in future but not a priority now) and the rest a very large digital photography collection, photo programs include the aging Aperture and a future forced switch to alternative products. Thanks for your thoughts and sorry for the long post! Maybe use all the extra 2TB drives I will have laying around in some sort of cold-storage idea. Get a faster externally facing PCIE Sas Card to connect to a raid exclosure + future proof data? Some combination of above + PCIE blade like Samsung XP941 SM951?īuy a new video card for parallel processing (which one would be a great price / cuda performance).
*4x4TB platters in raid 01 in standard bay with known vendor solution *Areca PCI mini-sas RAID card with two internal sas to sata ports connected to both Speed and expand the internal I/O + storage I would love suggestions on these potential choices:
#Areca vs softraid upgrade#
Short of buying a new MacPro and maxing it out I'd like to really upgrade the current machine to last for at least another 3 years (maybe even 4 which would put it close to a 10 year lifespan!). I do notice my disk I/O is particularly slow with about 200 MB/S read/write on the 4TB spinning platter RAID and some severe wait times loading and unloading Genomics data or large Aperture Libraries so I'm definitely going to get rid of the Apple Raid card! My question is given a particular starting point, what is the best bang-for-the-buck for my particular use case (see below "USE CASE"). I've looked at these and other forums for CPU, SSD, PCIe Host adapter and PCIe Blades. Many external hard-drives !!! in enclosures or bare with a NewTech Voyager Q reader Quad Hitachi Hds722020ala330 2TB Hard Drive, 7200rpm, SATA 3.5 - connected to Apple Raid Card as 4 terabyte RAID 0-1*Įxternal Drobo S currently with 5 2 TB commodity drives My current configuration is as follows (* next to what I am contemplating upgrading / replacing).ĭual OWC Mercury EXTREME Pro SSD RAID 0 - Optical Bay using Softraid* I'm leaning towards an internal PCIe RAID card + a bunch of SSD and spinning disks. I would love some input on what to upgrade for my Mac Pro 4,1 to squeeze the most out of it performance wise for a fixed budget of about $3K.
