Going to buy an iMac by the end of this month (whether there's a new one released or not) and I'm going a little nuts on possibilities for storage to have attached to it. I was planning to run everything I could from my NAS, but with all of the SMB problems I'm having on Mojave (semi-fixed on 10.14.1 but still not where it should be) I'm thinking I need to keep some direct attached storage around (at least 1TB flash). I've been going back and forth and will probably go with one of these options: 1. Two SATA SSDs in RAID 0 (obviously keeping a backup). Micro Center currently has 512GB Intel 545s drives for $75, coupled with some USB enclosures it would probably come in under $200 for 1TB. Figured I could have them both connected at all times to the USB-A ports and have Disk Utility create the striped volume and theoretically in certain instances I'd get 10Gbps across the volume. 2. M.2 NVMe SSD in a USB-C 10Gb enclosure. Would be roughly double the cost (probably around $400-$450 with the enclosure), but then it's a smaller device to keep attached. But then I'm also wasting the bandwidth of the drive by a few hundred MB/s. Wouldn't go for a Thunderbolt enclosure because I'd like for it to be bus powered (all I've seen need external AC power). 3. Option the iMac with a 1TB SSD from Apple. The most expensive, but also the fastest. But for my needs, I wouldn't really be exploiting all of the bandwidth that the drive has to offer anyway. Also then it would be quite difficult (if even possible) to repurpose the drive in the future. When I order, at least a 256GB SSD will be specified instead of a Fusion Drive. These are kinda just the thoughts running through my mind about it, but thought I'd post to see if anyone has some input.
