5 Reasons Against

Alienware Only Has Unexceptional Computer Reviews

Whilst Alienware is one of the ok PC brands according to average reviews from experts and owners, Alienware has good reviews specifically within its medium processor core personal computers range.

Only HDD Storage Medium

The storage speed of this PC is HDD, which is typical of many medium processor core personal computers that were released more than a year ago. A Hard Disk Drive (HDD) is the traditional storage method for computers. A HDD stores the information on magnetic disks. HDD drives are cheap, but they are slower than Flash and SSD bases storage systems.

We compared all the other HDD PCs to this computer and we think the DELL OptiPlex 9020[plb_2395416_price], and the Acer Aspire XC-705[plb_3121374_price] which is cheaper is also worth considering.

If the storage speed of this Alienware PC is not fast enough for you then you might also want to consider the OptiPlex 7020 MT[pl_2788976_price] (SSD), or the OptiPlex 3020 SFF[pl_2867167_price] (SSD) both from DELL or the Zoostorm Intel Core i5 Delta[plb_2756335_price] (SSD) which is also cheaper.
