Hard Drive Raids obsolete for most projects?

The $/GB still favors spinning disks. My Synology 1821+ with 10GigE, NVME cache drives and 100TB of spinning disks still gets 1000MB/s read & write speeds so I can edit uncompressed 4K video.

Migrating from PC to Mac, what to do about hard drive file system formats?

Do NOT use exfat for extended use on both systems. It is not journaled, and is therefore very easy to corrupt. I lost many terabytes during my Mac to PC switch by using exfat drives. I believe the only appropriate use for exfat is to write data once, read it once, and format the drive for the next u

NAS setup for small team, hybrid workflow

Good morning. Your "Synology rep" - really ? using an iSCSI LUN has nothing to do with remote editing. For your simple application - all you need to do is connect via the built in SMB network protocol, which is both on your Mac (and any office PC) and the Synology. To do professional video editing,

State of UGreen vs Synology

Yeah, i got a 4800+ at the kickstarter. It really is kinda basic hardware compared to computers out today, but its so much faster than the synology in every measurable way. The 10gbe network is a must have. I genuinely think that Synology management has never used their own products. Its been great,

Current favorite external SSDs for cache?

Crucial X9 is working great for me connected to M2 Mac Studio. Using in concert with Synology 1821+ HDD RAID NAS. That said, it appears you may need more speed than me. I’m totally content with 1,050 MB/s. I believe the X10 is 2,000 MB/s.

What NAS are you all using?

Synology DS1821+, 32GB memory, 10GBe card and 8 x 18TB WD Red Pro HDDs. Run dozens of Docker containers on it and haven't felt the need for anything more powerful yet. Worth noting, no transcoding is done.

Looking for NAS Recommendations

What are you doing to those poor NAS's? I still use my 13yo DS413j for TimeMachine backups alongside my DS1817 (8yo) and DS1821+ (4yo) which are my primary storage and mirror. The two newer machines have been maxed out with RAM and 10GB cards and the DS1821+ has two M.2 cache drives. They have been

Stick with 6Ɨ4TB SSDs or move to large HDDs for a Plex NAS?

SSDs are wasted on a NAS, don't bother. The bottleneck is your network connection. Its like taking a 5 gallon bucket and dumping it into a drinking straw. Its not going to go through any faster than a regular water bottle. If you have SSDs laying around then use them, but you will get the same speed

Large storage (20-30TB) external HD recs?

I have a Synology DS1821+ with 8x 20tb Exos drives and a Chelsio 2 port SFP+ 10Gbps network card. It is friggin fantastic. Probably overkill based on what you said, but I think if you find a Synology with the network and storage capacity you need it's really hard to go wrong with them

Regretting 256 GB Storage A Year Later

I'm using my NAS as main storage, 10GbE connection between my Mac Mini M4 and my Synology DS1821+ with plenty of storage (80TB) and it always has a full backup in my vacation home so im gouing with the base model and doesn't use iCloud.
