looks like you have a 500GB (hdd?) drive split into 2 partitions. i would suggest you go for a similar 512 GB or higher capacity SSD. maybe even consider NVMe drives, if they're supported. kung kaya ng budget, syempre... o konting ipon pa, di pa naman puno ang hdd mo, eh.
at kung ito ang main computer mo, stick to the well known brands - samsung, kingston, crucial, at mga katulad nito. mas mahal for sure, pero 'yung lost data mo could be priceless.
