    Good performer, but makes me nervous

    • Written by from Denver

    I'm a long time user of Promise RAID systems. This is my first purchase of a Pegasus RAID, which isn't quite as full featured as their server class equipment, but it saves a ton of money since it uses Thunderbolt and forgoes the need for an expensive fiber-channel card.

    The one missing star is because this RAID only supports a very limited number of hard drives and those drives are fairly low-rated for reliability. For example, if you need to replace a 2TB drive, the only officially supported option is the Toshiba DT01ACA200. Check out the reviews on Newegg and you'll see why it makes me nervous.

    The only other options would be a 3TB or 4TB Seagate drive (ST3000DM001 and ST4000DM000 respectively). The former is also poorly rated and the latter is a waste of money and capacity, considering it will only use 2TB when added to your existing level 5 RAID.

    And what happens when these drives go EOL? Hopefully Promise will provide some more options, but this is an expensive purchase to base on hope.

    Overall, performance has been pretty good, but it's hard to wholeheartedly recommend a RAID with such limited drive support.

    -Promise Pegasus2 RAID 50 730mb write / 659mb read.

    Purchased one for testing and to help me decide whether or not to have more ordered for my students to use in my Final Cut Pro editing lab.

    So far, so good. Honestly, I'm very impressed with the ease of use and performance of this Pegasus2.

    Bought one of these for home use: photos, movies, etc. As the doc says, it does need some time to get itself ready for use. The management program is on the storage itself and works fine. Called support once (to see if unit can be laid on it's side - the answer is yes, it can) and they responded quickly.
