## Description

LaCie 2big Dock RAID, 20TB, externe HDD, for PC Mac iPad & iPhone, Data Rescue Service (STLG20000400) : desertcart.co.uk: Computers & Accessories

Review: Failed right from the start. - This is the third seagate 'raid' device that I have bought and used over the last few years. All of the previous ones have worked flawlessly. This one unfortunately was bad right from the start. It appeared to create a back-up but then 'told' me that the drive was inaccessible. (See the photo). I tried to set it up several times and each time got the same result- not much use if you need the drive to protect your files! An entire afternoon on-line to Seagate couldn't sort the problem out so the drive was eventually returned to the supplier who couldn't fix it either! They are now refunding the purchase price to my account. Thanks you.
Review: Highly Recommended - I already have a LaCie 2Big Dock Raid 16TB ThunderBolt 3 and this has been running for 5 years without a glitch. I have 2x 27" Monitors and using this drive allows my MacBook Pro to run 3 screens utilising the built in Hub. I have the Old Drive running Time Machine via Daisy Chain to the New Storage. No Glitching and No Speed dropouts noticed. I have everything connected via ThunderBolt 5 and the speed is amazing. I would Highly Recommend this product especially if your a Mac User. I just plug one cable in and everything fires up with no issues. One thing I have to note is you need to UnMount all the drives before unplugging but this is the norm for Mac. Both drives are Mirror Raid Just incase. I have partitioned the old drive so there are 2x 4TB Time Machine Drive, One is used for my Son and One for my Self these are password protected so on start up we just enter our password and eject the others unwanted Time Machine. the 32TB of this New HDD is Mirror for our Photo Sharing. I have every confidence in this product and Highly Recommend it, I would advise you consider the size and how you will use it before purchasing but I would assume anyone would do that.

### ⭐ FAILED AFTER ONLY 3 WEEKS!!
*by J***S on 26 June 2024*

Do not buy!! I had high hopes but this drive failed after only 3 weeks and lost all my data! On top of that to return it for a replacement or repair with Seagate, they expect you to pay postage and wrap it in very specific wrapping (in an ESD (electrostatic discharge) bag or in an anti-static plastic shell). AVOID AT ALL COSTS!!
