LaCie 2big Dock RAID, 20TB, externe HDD, for PC Mac iPad & iPhone, Data Rescue Service (STLG20000400)

I've been looking for a SSD based storage box to replace my SAN for some time but the cost was just too high so I bought this instead as a stop gap. 10TB is reasonable amount of storage but there are two things which have surprised me.Firstly it works really well with Apple Mac Mini (and therefore probably all Macs) - I don't get those annoying errors saying the device wasn't ejected properly - regardless of if I reboot the Mac or use the sleep function, the drive is available and connected when the Mac comes to life, no errors or delays.Secondly the speed ! It's much faster than any other external hard drive I've had. My Mac Mini has a Thunderbolt 3/USB 4 port being an M1 Mac Mini and although this drive doesn't support USB4 or Thunderbolt connections, it does enable it to run at full 10Gbit/s of USB 3.2 gen 2, which is the same headline speed at 10Gbit Ethernet, which is not really directly comparable, but does mean the the interface is never going to be the limiting factor, the speed limiter will be the disk and Lacie have fitted a fast disk which is giving me well over 220 MBytes/s read and write mixed file sizes. This is impressive for a spinning disk.Given the speed, the price and the build quality which is great (and I can't hear a fan) this is very good value for money.

It is really good itself. Quiet. Does not get warm. Does not vibrate etc. It comes in with all possible plugs I could think of as well which can be easily changed which is AMAZING. The software is simple to understand and so far, worked well.It has 1 semi-con and one real con.Semi-con - It is really heavy for how small it is. Not that you wont be able to lift it but surprisingly heavy.REAL con is the BLUE LIGHT on the front. It is extremely strong and cannot be turned off. You either have to cover it, paint it over or disassemble the device and somehow remove the led. Not only its constantly ON but it also rapidly flashes every now and then and when PC/Laptop is off, it will be off BUT it will still do that occasional flashing for no reason.So far it worked without any problems and the storage is big so that is fine. It mostly just comes to that damn light. It has its own software but you cannot disable the light which is sort of silly. Would be little better if it was not for the BRIGHT BLUE colour of it...

I bought this to use as a Time Machine/Acronis backup for an Apple M1 iMac. Generally it works well and is fast. I have had problems with a previous LaCie d2 professional that was disconnecting but I have had no problems with this one. Perhaps a firmware update has solved this? Having said that I have found this drive constantly cycles between power up and standby when seemingly not being accessed which is annoying seeing as I need almost silence in order to work. I therefore have resolved this by turning it off and backing up manually as and when needed. I don't generate many files so regular backups not really needed as I also use iCloud. Additionally I dislike the supplied cable. It is rather stiff, so rather than sitting on the desk and flowing to the drive it bends and twists up and down all over the place and looks messy. Shame because the drive is nice and well thought out.

There's a constant whine from the unit when idle, that I think is mostly from the cooling fan, but may be the hard drive itself spinning, or quite possibly both. It never sleeps. It never spins down and shuts the **** up. The usage pattern I have is that I may be using the computer it's connected to for hours without needing it, but then I go away and that computer becomes a server where I'm using content on that drive remotely. So, having it shut up when not being used would be nice.It may be macOS (Monterey)'s fault. I've told Spotlight to not index it, I've told it it can put idle disks to sleep, I've made sure nothing user-visible is looking at it. And yet, every few seconds, there's an access (by the sounds of it), and that's probably keeping it awake. If it is the fan, it's not as automatic as it's made out to be, as even when the drive is idle and the room it's in is frankly chilly, it keeps going. The only option is to actually eject the volume; that works, but then must be manually remounted using disk utility when I want it to be available for use.Apart from that it works great. It's just that it's almost as insomniac as I am. (I don't have an eject icon.)Edit:Naturally minutes after posting I figured it out. Clearly I needed to embarrass myself by making a public complaint first. Edited review in case it helps someone coming after:It does sleep. The thing that was preventing it sleeping, in my case, was CleanMyMacX, which generally speaking is a good thing, but either its menubar utility or the health monitor daemon was prodding the disk frequently enough to keep it awake. I'd forgotten about it until I ejected then remounted the disk and it offered to delete the trash on it.Disable background monitoring and quit all CleanMyMacX processes, and after a reasonable delay, the drive went to sleep just fine. Watch out for other similar utilities/processes that might be doing that kind of background monitoring, like antivirus tools, etc. At some point I'll get back to trying to figure out how to have CMMX working but not keeping that drive awake, for the time being, it's just disabled entirely.As that was the only problem I was having, added a star to the rating.
